Abstract:
[Objective]To explore the value of the application of the arthroscope in unicompartmental knee arthroplasty(UKA)for the patients with medial osteoarthritis of the knee.[Method]A clinical retrospective study has been done on 30 knees in 21 patients.The patients were evaluated in preoperative X-rays,physical examination,the knee society score(KSS)evalution,the presentation of arthroscopical examination as well as the ultimate operation method.[Result]Arthroscopic examination showed that the osteoarthritis were mainly located in medial compartment of the knee.Tibia terrace cartilage and condyle of femur showed outbrige Ⅲ～Ⅳ degrees degeneration.26/30(87%)of the patients showed medial menisci injury in different degree,and 4/30(13.3%)of the patients showed lateral menisci degenerated,and pathological changes of osteoarthritis were located at front medial compartment.And 19/30(63%)of the patients combined Ⅰ～Ⅳ degrees of localized or broad patellar cartilage degeneration,the lateral compartment normal or localized patellar cartilage degeneration less than Ⅱ degrees for all patients.The result of the arthroscopic examination was consistent with the preoperative clinical examination and the imaging examination.All the patients received Oxford Ⅲ prosthesis UKA by microinvasive approach and there was no case that had to change operation method due to arthroscope detection.[Conclusion]1.The main purpose for the application of the arthroscopic in UKA is to deal with other disease inside the knee rather than to confirm the indication of the operation.2.Arthroscopy is an effective way for the patients combined lateral menisci injury and other compartmental mild osteoarthritis.
