Abstract:
BACKGROUND:Surgical treatment for pigmented vil onodular synovitis can maximize the excision of synovial lesions and recovery of joint function.
OBJECTIVE:To investigate the knee joint function and relapse rate fol owing treatment of pigmented vil onodular synovitis with total knee replacement and arthroscopic synovectomy.
METHODS:We retrospectively analyzed 34 cases of knee pigmented vil onodular synovitis admitted for surgical treatment in the Department of Orthopedics, Xiangya Hospital of Central South University, China from December 2006 to December 2011. In these cases, 24 patients received arthroscopic synovectomy and 10 patients were subjected to total knee replacement. Adjuvant radiotherapy was conducted according to postoperative patient’s conditions. Lysholm scoring was employed in the arthroscopic synovectomy group, and American Knee Society scoring was used in the total knee replacement group. Knee function in two groups was compared before and after treatment. Fol ow-up observation was performed to compare knee function recovery and relapse rate between two groups.
RESULTS AND CONCLUSION:Thirty-four patients were effectively fol owed up for 12-66 months, mean 41.3 months. Statistical analysis showed that in the arthroscopic synovectomy group, the postoperative Lysholm score was (86.3± 10.3) points, significantly higher than the preoperative score which was (55.5±13.2) points (t=3.81, P=0.016, P<0.05). In the total knee arthroplasty group, the American Knee Society score was increased from (40.7±2.2) points preoperatively to (90.2±1.1) points postoperatively (t=6.27, P<0.01). In the arthroscopic synovectomy group, the American Knee Society score was increased from (34.2±3.9) points preoperatively to (80.8±1.9) points postoperatively (t=16.58, P<0.01). Arthroscopic synovectomy combined with adjuvant radiotherapy can achieve better outcomes in pigmented vil onodular synovitis patients, while the total knee replacement for advanced with advanced knee diffuse pigmented vil onodular synovitis is better to restore knee function and the recurrence rate is low.
