Objective  To investigate the short-term effectiveness of joint distraction by Ilizarov combined with arthroscopic debridement in the treatment of knee osteoarthritis (KOA). Methods  Between January 2014 and January 2015, 15 patients (15 knees) with KOA were treated using arthroscopic debridement assisting with the Ilizarov distraction technology. There were 7 males and 8 females, aged from 45 to 64 years (mean, 55 years). The left knee and the right knee were involved in 6 and 9 cases respectively. The disease duration was 2.0-9.5 years (median, 6 years). They all had received conservative treatment for 6 months and got poor clinical improvement. The preoperative visual analogue scale (VAS) score, the Western Ontario and McMaster University Osteoarthritis Index (WOMAC) score, the knee injury and osteoarthritis outcome score (KOOS), the range of motion (ROM) for knee, and the radiographic joint space width were 76.2±8.8, 59.3±5.7, 44.3±7.2, (75±21)°, and (2.5±0.4) mm respectively. According to Kellgren-Lawrence grade system, 11 cases were rated as grade III and 4 cases as grade IV. Results  There was no poor incision healing, infection, and deep vein thrombosis. All the 15 patients were followed up 12-18 months (mean, 15.5 months). Patients achieved pain relief. The knee activity was obviously improved. The postoperative VAS score, WOMAC score, KOOS score, and ROM at 12 months were 20.9±7.8, 38.2±5.5, 92.1±6.9, and (118±14)° respectively, showing significant difference when compared with preoperative ones (t=18.213, P=0.000; t=10.317, P=0.000; t=18.564, P=0.000; t=6.599, P=0.000). Postoperative X-ray film showed that joint space width at 12 months was (3.8±0.3) mm, showing significant difference when compared with preoperative one (t=10.070, P=0.000). Conclusion  Joint distraction by Ilizarov combined with arthroscopic debridement can effectively relieve pain, improve the function and quality of life. It was beneficial to cartilaginous tissue repair and delaying the degenerative process of KOA. The short-term effectiveness is satisfactory.
