Arthroscopic treatment and high tibial osteotomy with fixation of staple made of retention alligation for the treatment of osteoarthritis of the knee / 中国矫形外科杂志

ABSTRACT

[Objective]To evaluate the results of treatment with arthroscope and high tibial osteotomy with fixation of staple made of retention alligation for osteoarthritis of the knee,and to discuss the indication for this technique.[Method]From March 1999 to May 2003,42 arthroscopic treatment and high tibial osteotomies were performed in 34 patients.There were 6 men(8 knees)and 28 women(34 knees,with a mean age of 54.2 years(ranged,42～67 years.The average postoperative follow-up was 36 months(ranged,16～44 months.The indications for high tibial osteteotomy were unicompartmental osteoarthritis and varus malalignment.After arthroscopic treatment,a lateral closing-wedge osteotomy was performed with fixation of staple made of retention alligation.The arthroscopic examination showedplica synovialis in l0 knees,medial meniscus injuries in 12 knees,lateral meniscus injuries in 6 knees,articular cartilage injuries in 20 knees,body loose in joint in 7 knees,intercondylar fossa stenosis in 9 knees.Common peroneal nerve was not exposed and the periosteum opposite to the insicion position was left intact for sake of stability and acted as a hinge around which the wedge osteotomy was closed.The patients were reexamined to obtain a knee score,to make lateral andanteroposterior radiograph of the involved knee with the patient standing.[Result]During the follow-up,the patients showed satifying pain relief,improvement of joint function,correction of yams deformity.The average preoperative knee score was 53.714?6.7,The average postoperative knee score at the time of the latest follow-up was 91.02?7.7.Comparing preoperative with postoperative,there were significant differences(P
