Abstract：[Objective] To provide a comprehensive evaluation of arthroscopy in mini-invasive surgery of knee osteoarthritis at different stages. [Methods] 99 patients of osteoarthritis were divided into three stages (namely, early, medium and late stages) in relation to the Kellgren-Lawrence Scale and the Outerbridge Scale, among which 36 patients were at early stage, 40 patients at medium stage and 23 patients at late stage. All patients were given mini-invasive surgery with arthroscopy. The Lysholm Scoring system was adopted to grade and analyze the knee function before surgery, one month after surgery and one year after surgery respectively. [Results] All patients were received more than one year follow-up. The Lysholm scores of all patients were 52.7±4.7 before surgery, 80.0±5.5 one month after surgery, and 71.3±13.5 one year after surgery; the scores after surgery (both after one month and one year) were significantly higher than that before surgery（P＜0.05). The Lysholm scores of early-stage patients were 55.4±4.0 before surgery, 83.3±4.8 one month after surgery, and 80.9±4.9 one year after surgery; the scores after surgery (both after one month and one year) were significantly higher than that before surgery（P＜0.05). The Lysholm scores of medium-stage patients were 52.3±4.3 before surgery, 79.6±4.7 one month after surgery, and 74.9±6.2 one year after surgery; the scores after surgery (both after one month and one year) were significantly higher than that before surgery（P＜0.05). The Lysholm score of late-stage patients was 49.2±4.1 before surgery; the score of one month after surgery was 75.7±4.7, significantly higher than that before surgery（P＜0.05); however the score of one year after surgery was 50.1±7.6, showing no significant difference from that before surgery (P＞0.05). [Conclusions] Arthroscopy presents positive effect in mini-invasive treatment of early- and medium-stage osteoarthritis, but its effect in treatment of late-stage osteoarthritis is undesirable.
