Abstract：Objective: To explore the clinical effect of arthroscopic synovial debridement combined with anterior cruciate ligament (ACL) reconstruction for old ACL rupture. Methods: The clinical data of 76 patients with old ACL were retrospectively analyzed. All patients were given knee arthroscopic synovectomy, and patients who were combined with ACL reconstruction with remnant preservation were included in observation group (n=42), and patients who were combined with ACL reconstruction with remnant removal were included in control group (n=34). The knee stability, knee function (Lysholm knee joint score) and life affected degree [2000 International Knee Documentation Committee (IKDC) Subjective score] were compared between the two groups before operation and at 3 months, 6 months and 12 months after operation. The treatment effects at 12 months after treatment and the complications within 12 months were analyzed in the two groups. Results: At 3 months, 6 months and 12 months after operation, the anterior displacement relaxation of knee joints in the two groups was significantly lower than that before operation, and the index in observation group was significantly lower than that in control group (all P<0.05). The Lysholm knee score and the IKDC subjective score were significantly improved compared with those before operation, and the scores in observation group were significantly higher than those in control group (all P<0.05). At 12 months after operation, the effective rate of treatment in observation group was significantly better than that in control group (P<0.05). There was no significant difference in the incidence rate of complications between the two groups within 12 months after operation (all P>0.05). Conclusions: Knee arthroscopic synovectom+ ACL reconstruction with remnant preservation has prominent treatment effects, and it does not increase the risk of complications compared with the method of remnant removal, and it is beneficial to the early development of mechanism of knee stability and function recovery.
