Abstract Objective To evaluate and analyze the mid-term efficacy of multi-channel arthroscopic clearance in the treatment of diffuse pigmented villonodular synovitis of knee joint.Methods From July 2013 to December 2015,31 patients with diffuse pigmentation villonodular synovitis of knee joint were treated,including 12 males and 19 females.The average age was (49.4±15.4) years old.There were17 case of the right knee and 14 case ofthe left knee.All patients had varying degrees of knee swelling,pain and limitation of movement before surgery,and all patients received multi-channel arthroscopic lesion clearance and histopathological examination for diagnosis.The assessment was conducted by comparing the visual analogue score of pain,Lysholm knee score,international knee documentation committee (IKDC) score,and knee range of motion (ROM)before surgery and at the last follow-up.Results All the patients had stage I wound healing,the mean operation time was (79.0±26.1) min,the mean postoperative hospital stay was (5.5±2.3) days,no postoperative infection and complications.All the 31 patients were followed up for 61 to 90 months,the mean follow-up time was (74.0±8.9) months.All patients had no significant Knee swelling and pain at the last follow-up,and the range of motion of the Knee was significantly improved.The visual analogue scale (VAS) of pain decreased from (6.5±0.8) to (1.3±0.9) at the last follow-up,and the Lysholm knee score increased from (47.9±6.4) to (88.5±3.0).The IKDCscore was increased from (51.7±4.6) to (89.4±4.5),and the ROMof knee joint was improved from (88.9±9.7) ° to (126.1±7.9) °,the differenceswere statistically significant (P<0.001).In the last follow-up,4 of the 31 patients had postoperative recurrence,with a recurrence rate of 12.9%.Conclusion Multi-channel arthroscopic clearance is a minimally invasive,safe and effective treatment for pigmented villonodular synovitis of the knee joint,which has the advantages of less trauma,quick postoperative recovery,fewer complications and low recurrence rate.
