Physical Therapy after TKR

- See: Function and Activity after TKR 

- Post Operative ROM:
    - most important factor predicting ultimate ROM is range of motion before surgery; 
           - ref: Range of Motion Correlates with Patient Perception of TKA Outcome.
    - patients with significant stiffness before surgery will have the most difficulty gaining range of motion;
    - lateral retinacular release & sacrifice or retention of posterior cruciate ligament, do not significantly affect knee range of motion after surgery;
           - final ROM after knee arthroplasty is fairly similar among various prosthetic designs, and usually approximates 100 to 115 degrees; 
    - Knee Extension: - Flexion Contracture Post TKR
           - closed chain - press against the wall exercise;
           - patient places his/her back and buttocks agaist the wall - standing and slight crouched;
           - the operative leg is extended as much as possible with the foot on the floor;
           - the patiet then extends the knee, trying to fire the quadriceps as much as possible;
           - references: 
                 - Flexion Contracture Persists If the Contracture is More Than 15° at 3 Months After Total Knee Arthroplasty

    - Continuous Passive Motion: 
           - may decrease DVT/PE in TKR: 
           - use of CPM may result in faster recovery of motion immediately after surgery, but appears not to
                    ultimately increase ROM at one year post surgery;

                    - Knee flexion significantly reduces blood loss and transfusion rate after uncemented total knee arthroplasty

- Early Loss of ROM:
    - manipulation may be indicated in some cases of limited postoperative knee flexion (up to 7% of patients);; 
    - manipulation: 
         - in the study by Esler CNA, et al, manipulation under anesthesia was performed on 47 knees;
               - patients were considered for manipulation if their flexion was less than 80 deg at at mean of 11 weeks postop;
               - goal was to overcome intra-articular adhesions.
               - the authors felt that delaying manipulation well beyond the timing of earlier studies was important in maintaining gains in flexion;
               - it was found that the mean gain in flexion at one year was 33 deg;
         - complications of manipulation:
               - hemarthrosis;
               - supracondylar femur fracture;
               - wound dehiscence
               - patellar tendon rupture;
         - reference:
