Arthroscopy following total knee arthroplasty

Conservative treatment had previously been used in our institution to treat the painful stiff knee joint following total knee arthroplasty (TKA). However, the result was not satisfactory. Arthroscopic surgery was then performed in 11 patients with painful knee joints with limited motion who had previously undergone TKA. Good results were achieved in eight patients. An average improvement of 56.3 degrees was achieved for knee range of motion. Flexion improved up to 90 degrees in all patients in the early postoperative period following arthroscopy. However, the benefits declined with time. To avoid the potential complications of manipulation and open arthrotomy, arthroscopic surgery is an option for treating the painful stiff knee joint.
