Abstract:

BACKGROUND: Total knee arthroplasty used for the treatment of knee joint deformity is difficult and involves multi-aspects, including the surgical approach, intraoperative osteotomy, order, method and extent of soft tissue release and soft tissue balance, There are a lot of controversies due to different scholarly opinions.
OBJECTIVE: To explore the surgical methods and clinical efficacy of total knee arthroplasty for the treatment of severe knee disease.
METHODS: A total of 42 cases (48 knees) with severe knee disease and knee joint deformity were selected, and all the patients were treated with total knee arthroplasty using posterior stabilized prosthesis. Through patellar medial approach and correct osteotomy, selective soft tissue release was performed to restore normal knee alignment and soft tissue balance to harvest knee stability. The targeted rehabilitation training was performed after replacement and the knee range of motion and maximum knee flex degree were detected regularly. The Hospital for Special Surgery score and the Western Ontario and Mcmaster Universities Arthritis Index score were performed.
RESULTS AND CONCLUSION: All patients were followed-up for 25 to 84 months, 35.5 months in average. The knee range of motion, maximum knee flex degree, Hospital for Special Surgery score and the Western Ontario and Mcmaster Universities Arthritis Index score of all the patients were significantly increased after replacement compared with those before replacement (P < 0.01). The wound was in stage Ⅰ recovery. No knee joint rigidity, blood vessel and nerve injury, patella fracture, patella low-site and prosthesis loosening were observed after replacement. The lower limb alignment was restored to normal level. The adult severe knee deformity can be corrected through total knee arthroplasty, and the function is improved significantly with satisfactory clinical results.
