  •   Objective  To analyze and compare the joint function and the improvement of joint pain in 26 patients with knee pigmented villonodular synovitis (PVNS) before and after arthroscopic synovectomy, evaluate the therapeutic value of arthroscopic treatment in patients with PVNS, and evaluate the effect of combined local treatment on the therapeutic effect of patients.  Methods  Twenty-six PVNS of the knee joint patients underwent arthroscopic synovectomy from January 2008 to December 2019 were analyzed retrospectively. Among them, 15 patients were treated with knee arthroscopy alone, and 11 patients were treated with local radiotherapy of diseased joints after operation. All 26 patients were followed up 88.6 (3-132) months. The joint pain score VAS score and knee function score Lysholm score were recorded before arthroscopic treatment and at the last follow-up, and the changes of VAS score and Lysholm score were statistically analyzed by t-test. The recurrence was determined by the joint swelling and pain and MRI evaluation results, and compared between the two groups.  Results  All 26 patients were followed up. The postoperative pathology showed that they were consistent with PVNS. The VAS score decreased from (4.60±0.88) points before surgery to (1.35±0.82) points at the last follow-up (P < 0.001), and Lysholm score increased from (41.00±7.45) points to (80.27±4.53) points (P < 0.001). The recurrence rate was 26.67% in the group receiving arthroscopy alone, and 9.09% in the group receiving arthroscopy combined with postoperative local radiotherapy (P>0.05).  Conclusion  Arthroscopy synoviectomy can relieve the pain and improve the joint function of the PVNS, and postoperative combined with local radiotherapy has a better therapeutic effect.
