Abstract
Background: Varus knee in adults is fairly common and considered the most predisposing factor for early medial compartment osteoarthritis of the knee joint. Patients and Methods: Fifteen patients underwent a medial open wedge high tibial osteotomy (MOWHTO) combined with arthroscopic evaluation for medial compartment osteoarthritis or intra articular pathology lesions. Measurements included mechanical axis of lower limb, hip knee ankle angle (HKA), posterior tibial slope angle, and medial proximal tibial angle (MPTA). Clinical evaluation was applied with Lysholm knee scoring scale and Knee Injury and Osteoarthritis Outcome Score (KOOS). Results: There were remarkable differences between the mean of pre and postoperative measurements at all angles including the preoperative mean varus angle 10.5◦ (range, 7◦-14◦), the postoperative mean correction angle 13◦ (range, 10◦-17◦), the preoperative mean posterior tibial slope 8.5◦ (range, 7◦-10◦), and the postoperative mean posterior tibial slope 8.8◦ (range, 7◦-10◦). A pathologic intra-articular lesion was detected in 13 of 15 patients during arthroscopic evaluation. Lysholm knee scoring scale was 68.8 preoperative and 93.7 postoperative, each subscale of Knee Injury and Osteoarthritis Outcome Score (KOOS) was calculated independently resulting in an improvement of 30-40%. Conclusion: Patients with varus knee, medial unicompartmental knee osteoarthritis, intra articular lesion, medial open wedge high tibial osteotomy combiend with arthroscopic evaluation is an excellent treatment option.
