UNICOMPARTMENTAL OSTEOARTHRITIS OF KNEE
The Professional Medical Journal
Osteoarthritis is more common in females because inpostmenopausal state, it is linked with high body weight, higher subcutaneous fat, deficiencyof calcium and weakness of muscles associated with changes in harmones. Objectives: Toassess the outcome of high tibial osteotomy in unicompartmental osteoarthritis of knee in termsof pain and improvement in function. Study Design: Prospective study. Setting: King AbdullahTeaching Hospital, Mansehra. Period: 1st January 2016 to 31st December 2017.
... ecember 2017. Materialsand Methods: Two hundred and forty eight cases were included in which twenty cases wereoperated by the use of modified coventry technique, twenty cases were operated by openwedge osteotomy with non locking plates as well as bone graft and remaining 208 cases wereoperated by medial open wedge osteotomy and iliac graft secured by locking plate. In all casesat eight weeks, six weeks and third post operative day respectively allowed full weight bearing.Post-operative changes in tibio femoral angle included in radiographical analysis. 2 years meanfollow-up of all these cases. Results: Function score and pain of knee improved considerably asthe p value <0.001 in our study. Maximum pain score is 50, pre-operatively average pain scorewas 18±7 and 44±5 was postoperatively. There was a significant improvement at two years inthe function of cases 244 (98.38%) according to grading used for judgment of function in kneescore. Pre-operatively mean functional knee score in 110 cases (88.70%) cases were 28.86,(100 is the maximum functional knee score) and 70.45 was post-operatively. In tibiofemoralangle there was a correction of 5.2±1.5 degree varus preoperatively and postoperatively aswell as valgus 5.8±1.3 degree respectively. Conclusion: In function and pain of the knee,there was significant improvement after the deformity correction (p value <0.001). In 88.23%outcomes of high tibial osteotomy in knees rated as excellent. Due to associated comorbidityand excessive over correction, there were poor outcomes in two cases. There is significantassociation between the obtained postoperative valgus and relief in pain.
