Medial release is a commonly performed technique to improve surgical exposure and aid in joint balancing. It is thought to be linked to the postoperative incidence of pes bursitis. However, the effect of scalpel vs electrocautery techniques for subperiosteal release has not been examined for their potential effect on the rates of pes bursitis. This randomized clinical trial will assign patients undergoing TKA for osteoarthritis (OA) into either scalpel or electrocautery release groups for their operation and will be followed postoperatively at 3 weeks and 3,6, and 12 months in order to determine the effect of release technique on rates of pes bursitis. This study will take place at Emory Orthopaedics. Subjects will not be compensated. Patients presenting to the clinic for evaluation of TKA will be screened for their eligibility in this study and recruited as well as consented in the clinic. This study can advance current clinical knowledge by evaluating two common surgical techniques to determine which may lead to better outcomes for patients undergoing TKA, a common orthopedic procedure, and reduce dissatisfaction as well as pain following operation.
