Abstract:
OBJECTIVE: To investigate the clinical effects of individualized repair and reconstruction surgery for multiple ligament injury and dislocation of knee joint based on stage classification diagnosis. METHODS: From January 2018 to January 2019, 42 patients with multiple ligament injury and dislocation of the knee joint were treated. There were 27 males and 15 females, aged from 30 to 63 (47.35±11.90) years old, including 17 left knees, 23 right knees and 2 bilateral knees. All patients with multiple ligament injuries and dislocations of the knee joint were classified by stages and improved Schenck diagnosis. Among them, 23 cases were in acute stage (≤3 weeks), 19 cases were in old stage (>3 weeks), 27 cases were type Ⅲ dislocation and type Ⅳ dislocation. There were 9 cases of dislocation and 6 cases of type Ⅵ dislocation. The corresponding repair methods such as closed manipulation and open release reduction, direct suture of ligament, anchor suture, bone penetrating suture, and routine ligament reconstruction were performed. The corresponding "progressive progressive excitation" rehabilitation program was adopted after the operation. After 2, 4, 6, 8 weeks and 3, 6, 9, 12 months after operation, the outpatient consultation and evaluation of knee joint function and stability were completed. The knee joint stability, excellent and good rate, disability rate and complication rate were compared before and after operation. Internation Knee Documentation Committee (IKDC) grade, IKDC subjective score, Lysholm score and Tegner score were used to evaluate knee joint function. RESULTS: All patients completed the outpatient follow-up and follow-up on schedule. All patients had gradeⅠwound healing, 4 patients had lower extremity venous thrombosis after operation, and there were no serious complications after anticoagulant treatment; 5 patients with common peroneal nerve injury were treated with release surgery and active postoperative rehabilitation, and neurological function gradually recovered. At 12 months after operation, the muscle strength of the affected limb reached grade Ⅴ and the active and passive range of motion recovered to more than 120 degrees. In the acute stage, the IKDC subjective scores were 20.46±12.61, 22.58±16.83, 0.71±1.14, 69.55±16.57, 77.73±15.14 and 3.14±1.67, respectively. One year after operation, IKDC subjective score was 67.04±19.07, Lysholm was 74.87±14.58, Tegner was 3.06±1.70, and 6 of them were grade A. After 12 months, the knee function scores of all patients were significantly improved compared with those before operation(P<0.01). CONCLUSION: According to the classification of multiple ligament injuries and dislocations of the knee joint, the corresponding surgical repair and reconstructiontreatment were adopted, and the corresponding rehabilitation program was adopted after the operation. The patients achieved good clinical treatment effect 12 months after operation, and the patients' satisfaction was high, which improved the excellent and good rate of treatment and reduced the disability rate.
