Osteoarthritis (OA) stands out as the most prevalent joint disease. It manifests as a progressive degradation of articular cartilage, new bone growth and often synovial tissue proliferation, resulting in pain and compromised joint functionality, ultimately leading to disability. Misalignment of the lower limb (varus or valgus knees) are recognised as a risk factor for osteoarthritis onset and progression. High tibial osteotomy (HTO) is a surgical technique that allows to shift the load from the affected area to other areas with intact cartilage. Similarly to HTO, braces realign the lower limb, without the need for surgical intervention. These corrective treatments are recommended for the youngest group of patients as it allows them to stay active, as opposed to Total Knee Replacement (TKR). Until today, the effects of braces and HTO on the subchondral bone microstructure and cartilage are not well understood. Investigating these aspects to better understand treatment failures is becoming more and more crucial because global prevalence of knee OA is expected to increase with the ageing of populations.

Patellofemoral joint (PFJ) pain is a common, often chronic, aching pain behind or around the kneecap, frequently called "runner's knee". It occurs when the kneecap does not glide smoothly over the thigh bone, often due to muscle weakness or overuse. It makes sitting for long periods, climbing stairs, or kneeling painful. Symptomatic knee osteoarthritis (OA) is a common, long-term condition where the protective cartilage in the knee joint wears away, causing the bones to rub together, leading to daily pain and stiffness. In simple terms, it is a "wear-and-tear" disease of the entire joint that makes walking, climbing stairs, or bending the knee difficult. The PFJ is where the patella (kneecap) meets the femoral trochlea (front part of the lower thigh bone) at the front of the knee. Patellar tracking refers to the movement of the patella that begins to engage in the distal femoral trochlear groove (smooth, U-shaped groove at the bottom of the thigh bone). By doing this study, we hope to advance clinical knowledge of the PTJ features in a more natural position by using weight-bearing computed tomography (WBCT) images while the leg is straight and slightly bent. Determining links between specific knee symptoms and the PTJ structure on WBCT images could enable providers to effectively target the underlying causes and to develop targeted treatments.

Osteoarthritis (OA) is a major public health problem, and involvement of the knee is especially disabling. Symptomatic knee OA has an incidence rate between 40 to 1,020 per 100,000 person years1 and is among the most common causes of disability worldwide. Knee arthritis pain and disability are highly comorbid wiht depression (30-50%). Currently available treatments offer only limited relief. The Pilot project aims to establish feasibility of the rTMS neuromodulation of response to Tai Chi and improvement in pain and comorbid depression in patients with knee OA. There are several ways in which the pilot project will improve scientific knowledge, and clinical practice: 1) The sequential stimulation of two targets (M1 and l-DLPFC) has not been systematically examined for the treatment of comorbid MDD and knee OA. We hypothesize that using a multi-target rTMS strategy combining M1 and l-DLPFC- active targets will be well tolerated and more effective to treat comorbid symptoms than single site rTMS to M1+l-DLPFCsham. This hypothesis will be tested in Aim 1 of this proposal by comparing two experimental conditions: A) M1active and l-DLPFCactive; and B) M1active and l-DLPFCsham. 2) Identifying the relationship between improvement in pain and depression to improvement in pro-inflammatory cytokines would be novel. Adding an rTMS as a neuromodulation technique with novel stimulation sites to assist in the reduction of symptoms of pain and depression is another scalable to clinical use opportunity that will provide pilot data for future clinical trials. We will perform a pilot feasibility trial of rTMS for those presenting with knee osteoarthritis related pain and moderate to severe depression in 30 volunteers who are undergoing Tai Chi intervention. Tolerability and safety of rTMS added to Tai Chi will be assessed along with changes in symptoms of pain and depression, in preparation to future R-01 applications.
NCT07460466
This study aims to compare the effectiveness of eccentric and concentric quadriceps femoris strengthening exercises in patients with knee osteoarthritis. Knee osteoarthritis is a common musculoskeletal condition that causes pain, reduced joint movement, muscle weakness, and functional limitations. Participants will be assigned to perform either eccentric or concentric unilateral open kinetic chain quadriceps exercises using isotonic loading based on a 10-repetition maximum (10-RM). The exercise program will be conducted three times per week for six weeks. The primary objective is to evaluate differences in quadriceps muscle strength between the two exercise approaches. Secondary outcomes include changes in knee range of motion and functional capacity measured using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). The results of this study are expected to provide evidence to guide exercise prescription in rehabilitation programs for patients with knee osteoarthritis.
NCT07456254
Knee osteoarthritis (OA) is a common degenerative joint disease that leads to pain, reduced mobility, and functional limitation. Quadriceps femoris weakness plays a significant role in disease progression and disability. Isotonic strengthening using the N-K Table allows adjustment of load angles to optimize muscle activation; however, the effect of different load angles on quadriceps activation in patients with knee osteoarthritis remains unclear. This study aims to compare quadriceps femoris activation at 0° and 50° N-K Table load angles in patients with knee osteoarthritis using surface electromyography (sEMG). A randomized cross-over experimental design is applied to determine whether adjusting the load angle improves maximum voluntary contraction (MVC) during isotonic knee extension exercise.
NCT07224958
The aim of this study is to conduct a comparative evaluation of the ROAM OA Single Upright Brace and the Ossur Unloader One Knee Brace in subjects with medial compartment osteoarthritis. The focus is on comparing the immediate and short-term biomechanical effects of these braces on knee adduction moments and spatiotemporal gait parameters, as well as assessing the long-term efficacy of the ROAM OA brace in improving pain and functional outcomes for individuals with osteoarthritis.
NCT03706521
The purpose of this study was to evaluate the safety and efficacy of lorecivivint (LOR) injected in the target knee joint of moderately to severely symptomatic osteoarthritis (OA) subjects. Efficacy was primarily evaluated via magnetic resonance imaging (MRI).
NCT07442812
This prospective observational cohort study aims to evaluate the association between perioperative dexamethasone administration and early postoperative recovery following primary total knee arthroplasty. In routine clinical practice, dexamethasone may be administered orally, intravenously, or not administered, depending on the surgeon's established perioperative protocol. The primary objective is to assess early postoperative recovery in terms of pain intensity, functional mobility, and knee joint range of motion. Secondary objectives include evaluation of inflammatory response, postoperative metabolic changes, opioid requirement, and the severity of postoperative nausea and vomiting (PONV). Group allocation is non-randomized and determined solely by the standard perioperative management approach routinely applied by the surgeon selected by the patient. No additional interventions are introduced for research purposes. All outcomes are assessed prospectively during the early postoperative period.

The Effect of a Novel Joint Distraction Knee Orthosis for Treating Medial Knee Osteoarthritis
NCT03564730
The purpose of this study is to assist surgeons and patients in answering the question "Should I have both knees replaced at the same time, or should I just do one and wait to do the second one?"
NCT06721897
We live in an increasingly aging society in which the incidence of osteoarticular diseases increases, among which osteoarthritis (OA) stands out. OA is a degenerative disorder of the different components of the joint leading to a progressive destruction of the same. The hip and knee being the most affected joints, OA presents multiple symptoms such as pain, stiffness and functional limitation, also causing psychological disorders such as anxiety, depression, quality of sleep and poor perception of quality of life. Conventional treatment is aimed at alleviating symptoms, but when conservative therapies fail in the more advanced stages of the disease, total joint replacement surgery or arthroplasty is the therapeutic option of choice. Strength physical exercise (PE) and aerobic training have been shown to be effective in OA, obtaining positive effects on the symptoms and on variables that deteriorate this disease. The concept of pre-habilitation or preoperative rehabilitation has been shown through other studies in different pathologies (cardiopulmonary and musculoskeletal) to have positive effects at a clinical and functional level, however, the planning of a pre-habilitation protocol in hip or knee arthroplasty is still controversial. The purpose of this study is to determine the effect that a prehabilitation program will produce and its possible usefulness in those subjects who are waiting for a hip or knee arthroplasty. It is expected to find favorable results that support this therapy when it comes to reducing postoperative recovery times, functional capacity and other psychological variables of interest. This powerful tool could represent a non-pharmacological and non-invasive therapy, as well as being useful and economical in the management of patients with OA in advanced stages.

Knee osteoarthritis is a degenerative condition that is prevalent in older population and is associated with pain, stiffness, decreased range of motion and impaired function. Physical therapy techniques, such as Mulligan's Pain Release Phenomenon and Kaltenborn Mobilization are used to alleviate patient's symptoms. A Randomized Clinical Trial was conducted at SAP Rehab Center (Saira Memorial hospital) and Pak Health Care, Lahore. 44 participants age between 40-65 years with Knee Osteoarthritis were randomly assigned into 2 groups. Both groups underwent treatment three times a week for total of six weeks. Group A received treatment through Mulligan's Pain Release Phenomenon along with conventional exercises. Group B received treatment through Kaltenborn mobilization and conventional exercises. Convectional treatment started with hot pack for 10 minutes followed by ultrasound for 8 minute, the program indcluded a series of exercises (Hamstring stretch, Gastrocnemius Stretch, Soleus Stretch and Rectus femoris Stretch all for 3 set with 10 repetitions and 10 seconds hold. Quadricep setting exercises 1 set with 10 repetitions, Full arc extension and Straight leg raises 1 set and 10 repetitions. the exercises program ended with cycling for 2 minutes. Outcome measures were conducted through NPRS for pain, WOMAC for functional disability, Universal Goniometer for range of motion at baseline and after 6 weeks. Data was analyzed through SPSS software version 27. The aim of the study is to compare the effects of Mulligan's Pain Release Phenomenon and Kaltenborn Mobilization on pain, disability and range of motion in patients with early Knee Osteoarthritis.
NCT06600958
Knee osteoarthritis (OA) is an heterogeneous disease, both symptomatically and structurally, with very different evolving profiles. Although several serum, urinary or synovial biomarkers have been developed in knee OA, their interest as potential predictive factors of clinical and structural progression remains poorly known. Similarly, to date, no biological predictive markers of response to OA treatments have been validated, particularly for intra-articular treatments \[corticosteroids (CTC), hyaluronic acid (HA), platelet-rich plasma (PRP)\]. Finally, although cohorts of OA patients have already been established in the past, none of them has made it possible to establish a biobank of serum and synovial fluid obtained from the same patient at inclusion but also during the follow-up of the OA disease, up to the joint replacement. The investigators hypothesize that some biomarkers in serum, PRP and synovial fluid in knee OA: * are be correlated with the clinical symptoms and radiological lesions, thus allowing to define distinct clusters of patients whose clinical and radiological evolving profile could be different * are correlated with the clinical evolution (pain and functional limitation) * can predict the radiographic progression but also in the long term the necessity of joint replacement * could constitute predictive factors of response to intra-articular treatments (CTC, HA and PRP). To validate theses hypothesis, investigators will conduct a longitudinal cohort study with long term follow-up until joint replacement in patients with knee OA. In parallel to this longitudinal study, a cross-sectional ancillary study will be conducted to compare the levels of different serum and synovial biomarkers between subjects with knee OA and subjects with chronic inflammatory rheumatism (rheumatoid arthritis, spondylarthritis) A/ Main objectives: \- Longitudinal study To study the correlations between changes in clinical symptoms (pain, function, quality of life, effusion, flare-up) / radiographic progression during the follow-up on the one hand, and the levels of biomarkers in serum, PRP and synovial fluid at inclusion / their variations at different times of the study on the other hand. B/ Secondary objectives * Longitudinal study 1. To study the correlations between clinical (pain, function, quality of life, effusion, congestive flare) / radiographic phenotype on the one hand, and serum, PRP, and synovial biomarker values at each follow-up visit. 2. To assess the prognostic value of clinical, biological or clinico-biological clusters on the ultimate outcome of OA defined by joint replacement. 3. To assess the prognostic value of different serum and synovial biomarkers on the structural progression during the follow-up. 4. To assess the prognostic value of different serum and synovial biomarkers on the efficacy of different intra-articular treatments (CTC, HA, PRP) 5. To assess changes of clinical symptoms, radiological grades and biological markers after different intra-articular treatments (CTC, HA, PRP) 6. To study the distribution of cellular populations in the joint fluid (synoviocytes, macrophages, lymphocytes, mesenchymal stem cells) according to the clinical and radiographic phenotype 7. To assess the correlations between the level of different biomarkers in serum, synovial fluid and their levels on tissue samples from OA joint obtained during joint replacement. 8. To study in vitro the effect of purified glycosamninoglycan (GAG) from synovial fluid and PRP on the metabolism of synoviocytes, macrophages and mesenchymal stem cells from autologous synovial fluid 9. To study in vitro the effect of purified GAGs from synovial fluid and PRP on the metabolism of synoviocytes, chondrocytes, mesenchymal stem cells obtained from human joint tissue samples (synovial membrane, cartilage) obtained during joint replacement. * Cross-sectional study 1. To assess the correlations between clinical symptoms (pain, function, quality of life, effusion, congestive flare) and radiographic phenotype and serum and synovial biomarkers at inclusion. 2. To compare serum and synovial biomarkers between subjects with knee OA and those with chronic inflammatory rheumatism (rheumatoid arthritis, spondyloarthritis) at inclusion. Method: 300 patients with knee pain related to knee OA (n=200) or chronic inflammatory rheumatism (spondylarthritis and rheumatoid arthritis) (n=100) requiring arthrocentesis and/or intra-articular injection will be enrolled in the Rheumatology department from Henri Mondor Hospital. A longitudinal follow-up will be proposed to patients with knee OA in addition to the participation in the cross-sectional study. The follow-up will include at least one visit each year or more in case of painful flare-up or new intra-articular injection. The follow-up will last a maximum of 10 years or less in case of joint replacement.

Osteoarthritis (OA) is a chronic, degenerative joint disease associated with aging and is recognized by the World Health Organization as a primary health condition. It is one of the leading causes of chronic disability worldwide. Structural changes occurring at the bone and joint margins in OA lead to a variety of symptoms and clinical findings associated with the deterioration of articular cartilage integrity. Clinical guidelines recommend a combination of exercise therapy tailored to individual needs, weight loss, and patient education prior to considering arthroplasty. However, achieving satisfactory long-term outcomes remains challenging, as patients are often unmotivated to adhere to training programs involving functional strength and mobility exercises unless they are supervised by a physiotherapist. Basic Body Awareness Therapy (BBAT) may serve as an alternative exercise method with a higher potential for sustained effects. BBAT is a movement-based therapy applied to daily life activities, focusing on body alignment and movement quality. Through the learning process of BBAT-by doing, reflecting, and transferring body awareness into everyday movements-it is hypothesized that patients gain self-efficacy and skills essential for maintaining independent and continuous exercise. BBAT is a body-mind therapeutic approach that emphasizes awareness of body sensations and movement patterns, aiming to restructure body awareness and motor control through individual experience. Increased attention to movement and bodily experiences enhances awareness of both physical and mental aspects. Through specific exercises, BBAT helps to reveal and improve the interaction and synergy between body and mind, thereby promoting postural stability, movement fluidity, and awareness of bodily reactions and internal resources. By encouraging reduced energy expenditure during daily activities and improving movement quality through self-exploration and experiential learning, BBAT contributes to improvements in postural imbalance, muscle tension, and bodily dysfunction. BBAT movements are simple, comfortable, balanced, and based on repeated experiential learning. Exercises are performed in various positions, including lying, sitting, standing, and walking. Physiotherapists guide patients using both physical and verbal cues to facilitate improved postural control, balance, and breathing during movement. Central sensitization may lead individuals with osteoarthritis to perceive normal bodily functions as painful, resulting in compensatory and dysfunctional movement strategies. It has been reported that mindfulness-based and body-mind therapies can reduce pain and symptoms while improving physical function in clinical management. Moreover, as emphasized in the recommendations of the Osteoarthritis Research Society International (OARSI), active patient involvement in health management is a core component of body-mind therapies such as BBAT. Despite these potential benefits, there is a limited number of studies investigating the effects of BBAT in individuals with osteoarthritis. Given that BBAT requires no equipment, can be practiced in any setting, promotes social engagement through group-based sessions, enhances relaxation and mind-body awareness, and reduces stress and anxiety, it may represent a favorable alternative exercise model. Additionally, BBAT may improve exercise adherence and contribute to reducing healthcare burden and associated costs. Comparing the effects of different therapeutic programs across multiple outcome parameters may help identify the most effective interventions for individuals with osteoarthritis, thereby improving clinical outcomes. In this context, the present study aims to compare the effects of Basic Body Awareness Therapy, applied in addition to conventional physiotherapy and a home exercise program, on pain, muscle strength, range of motion, balance, active joint position sense, functional outcomes, pressure pain threshold, kinesiophobia, and quality of life in individuals with knee osteoarthritis.
NCT07386600
This randomized, double-blind, controlled trial is designed to compare the analgesic efficacy and safety of perineural dexamethasone versus perineural dexmedetomidine as adjuvants to ropivacaine for ultrasound-guided interspace between the popliteal artery and the capsule of the posterior knee (iPACK) and adductor canal blocks in patients undergoing primary unilateral total knee arthroplasty (TKA). Elderly participants scheduled for elective TKA will be randomized into three parallel groups: ropivacaine alone (control), ropivacaine combined with perineural dexamethasone, or ropivacaine combined with perineural dexmedetomidine. The primary objective is to determine whether the addition of either adjuvant reduces postoperative opioid consumption compared with ropivacaine alone and to assess potential differences in analgesic efficacy between the two adjuvants. Secondary outcomes include pain intensity at rest and during mobilization, time to first rescue analgesia, quality of early functional recovery, and the incidence of adverse events, including postoperative nausea and vomiting, motor impairment, and hemodynamic instability.
NCT06290336
The goal of this multi-center randomized controlled trial is to investigate the effect of pre-operative exercise therapy and education for patients awaiting knee replacement surgery on subjective knee function, patient satisfaction and enablement compared to standard care. The main questions it aims to answer are: * Does pre-operative exercise therapy and education lead to better subjective knee function compared to standard care one year after surgery? * Does pre-operative exercise therapy and education lead to a higher level of patient satisfaction compared to standard care one year after surgery? * Does pre-operative exercise therapy and education lead to better patient enablement compared to standard care six weeks after surgery? * Does pre-operative exercise therapy and education lead to better objective knee function compared to standard care six weeks after surgery? Participants will be randomized stratified by age (≤ 67 years, \> 67 years) to either pre-operative supervised individualized exercise therapy combined with education two sessions/week (intervention group) or to standard care (control group). The intervention will be continuously ongoing for at least eight weeks from the point of decision for surgery until as close to the surgery as possible.
NCT07288970
This study will compare two regional anesthesia strategies for pain management after total knee arthroplasty in adults. Both strategies use an adductor canal block (ACB) to provide analgesia while preserving quadriceps muscle strength. The ACB is then combined with either a sacral erector spinae plane block (S-ESPB) or an iPACK (infiltration between the popliteal artery and the posterior capsule of the knee) block to improve posterior knee analgesia. All patients will receive an ultrasound-guided adductor canal block with 20 mL of 0.2% ropivacaine. They will then be randomly assigned to one of two groups: Group 1: ACB combined with a sacral erector spinae plane block (S-ESPB) using 20 mL of 0.2% ropivacaine. Group 2: ACB combined with an iPACK block using 20 mL of 0.2% ropivacaine. Both techniques aim to provide effective postoperative analgesia while minimizing motor blockade and allowing for early mobilization. It is not known whether combining ACB with S-ESPB or with iPACK provides superior pain control, reduces opioid requirements, or results in better functional recovery after total knee arthroplasty. The main purpose of this study is to compare the time to first rescue analgesia and overall postoperative pain control between the two regional anesthesia strategies. The study will also evaluate opioid consumption, motor function, functional mobility, side effects, and block-related complications. We hypothesize that both combinations will provide effective analgesia, but their impact on pain intensity, duration of analgesia, and functional recovery may differ.
