The goal of this prospective, randomized study is to compare the outcomes of patients undergoing primary total knee arthroplasty (TKA) after photographing final knee range of motion immediately postoperatively and sharing these photographs with patients at their first follow-up appointment versus a group that does not see a photograph. The knee will be photographed in maximum flexion and extension. The primary objectives will be to compare the range of motion of the operative knee at 2 weeks and 6 weeks postoperatively. In the investigator's institution, patients who have failed to achieve 90 degrees of flexion at a postoperative period of 6 weeks undergo manipulation of the knee under anesthesia (MUA). The investigators will also measure how many patients require MUA in the photograph group and non-photograph group. MUA will be performed if patients fail to achieve 90 degrees of flexion at 6 weeks post-op.
