Correlation Between Deficits in Knee ROM Recovery and Difficulty in Dorsiflexing the Tibio-tarsal Joint in Patients Undergoing Total Knee Replacement Surgery.

To demonstrate that the deficit in dorsiflexion-tibia-talar joint range of motion can have an effect on the knee operated by arthroplasty by limiting full extension and, in general, the recovery of a full range of motion.

The study is of a prospective, prognostic, observational nature and involves all patients who are candidates for admission to the Rizzoli Orthopaedic Institute for primary knee replacement surgery, recruited in the Orthopaedics department and subsequently followed in the Rehabilitation Medicine department of the DRS. The recruited patients will be subjected to pre-operative measurement of the ankle ROM; if they present a limitation of the same, they will be included in the exposed group, alternatively they will be included in the non-exposed group.
