Abstract | BACKGROUND: METHODS: From January 2008 to July 2011, TGCT was diagnosed incidentally in 10 patients (a total of 11 individual knees) undergoing posterior-stabilized TKA for an initial diagnosis of osteoarthritis. TGCT was confirmed by histopathology of biopsy specimens. Partial synovectomy was performed for localized-type TGCT (3 knees, 3 patients) and total synovectomy for diffuse-type TGCT (8 knees, 7 patients). RESULTS: All patients were female with a mean age of 61.7 ± 6.6 (range 50-70) years. No postoperative infection, nerve injury, or deep venous thrombosis occurred. All patients were followed up for a mean period of 60.9 ± 6.6 (39-83) months, and no recurrence of TGCT occurred. X-ray imaging showed no apparent radiolucent lines around the prosthesis, and no prosthetic loosening, subsidence, or osteolysis. The joints were stable, with a significantly improved range of motion following surgery (109.5° ± 8.8° vs 80.5° ± 16.8°, P < .01). The Knee Society scores for knee joint (90.0 ± 4.1 vs 40.5 ± 8.1) and knee function (81.8 ± 7.5 vs 35.0 ± 13.8) were both significantly improved after surgery (P < .01). CONCLUSION: Inactive TGCT could not be diagnosed preoperatively. TKA combined with synovectomy is effective in the treatment of advanced TGCT with degenerative lesions.
