Abstract
Fourteen patients were retrospectively reviewed to examine the role of arthroscopy in the diagnosis and treatment of the problem total knee arthroplasty (TKA), and to define parameters for indications, techniques, and results. All patients had undergone a previous TKA, and postoperatively had problems with pain and/or range of motion. Routine evaluation failed to reveal sepsis or aseptic loosening. Arthroscopy was used to evaluate and treat certain specific conditions. The arthroscope was successful in removing loose bodies, correcting patella subluxation with an arthroscopic lateral release, excising a symptomatic pseudomeniscus, and releasing intraarticular adhesions to improve motion and relieve pain. The postoperative knee score improved 73%. Arthroscopy is a valuable tool to evaluate a painful TKA, and can be used to treat certain conditions that would otherwise require an arthrotomy. The rehabilitation time is easier on the patient and much quicker. Arthroscopy of a TKA does not compromise any future procedures. However, it remains a technically demanding procedure whose indications and expectations are still being defined.
