详细说明

The management of medial compartment osteoarthritis of the knee in middle-aged patients is challenging. High tibial osteotomy (HTO) is a joint-preserving procedure that can relieve symptoms and return patients back to an active lifestyle. However, both total and uni-compartmental knee arthroplasty can provide good pain relief, but there is concern about the durability of the components in this younger population.

High tibial osteotomy (HTO) is a procedure with proven short-, medium- and long-term efficacy for treating isolated medial tibiofemoral knee osteoarthritis in young subjects with varus knee deformity.

Several studies have shown that the HTO lasts on average 10 years. After this, 74% to 96% of patients require total knee arthroplasty (TKA).

HTO can delay or sometime even avoid the need for arthroplasty. Better functional results have been seen in younger patients. HTO can also be performed to treat medial femoral condyle osteonecrosis or as part of the treatment of ligament injuries with varus malalignment.

The goal of high tibial osteotomy in knees with medial compartment OA is to shift the weight bearing axis from the medial compartment into the lateral compartment. This unloads the damaged medial articular cartilage. To achieve this, two main surgical techniques have been utilized, the lateral closing wedge and the medial opening wedge high tibial osteotomy (MOHTO). The lateral closing wedge HTO has the advantage of early bony healing at the osteotomy site.

参与者组/臂
干预/治疗
实验性的：Early weight bearing group
this group underwent High tibial osteotomy and started early partial weight bearing post-operative at week 2 using crutches. Quadriceps strengthening exercises, continues flexion and extension of the knee were added also to this protocol of post-operative rehabilitation.
其他：Early weight bearing post operative
this group underwent High tibial osteotomy and started early partial weight bearing post-operative at week 2 using crutches and restricted 20 kg of load for 4 weeks. Quadriceps strengthening exercises, continues flexion and extension of the knee were added also to this protocol of post-operative rehabilitation.
有源比较器：Non weight bearing group
this group underwent High tibial osteotomy and started weight bearing post-operative at week 6. Quadriceps strengthening exercises, continues flexion and extension of the knee were added also to this protocol of post-operative rehabilitation. this is a control group
其他：Non weight bearing Post-operative
the group underwent High tibial osteotomy and started weight bearing post-operative at week 6. Quadriceps strengthening exercises, continues flexion and extension of the knee were added also to this protocol of post-operative rehabilitation.

大体时间
Clinical outcome
大体时间：All patients of both groups underwent a clinical evaluation at 6-weeks, 3-months and 6-months post-operatively to assess knee range of motion and return to daily activity life.
We used The nternational Knee Documentation Committee (IKDC) score as a validated, patient-reported outcome measure designed to quantify functional limitations, symptoms, and sports activity levels across a broad range of knee pathologies. IKDC scores are utilized to objectively assess a patient's ability to perform activities of daily living and to establish data-driven benchmarks for Return-to-Sport (RTS). Furthermore, by providing a longitudinal perspective on recovery, the scale allows us to monitor the progression of clinical improvement and determine the overall efficacy of surgical and rehabilitative interventions. The IKDC utilizes a normalized scale ranging from 0 to 100. A score of 0 represents the lowest possible level of function, indicating severe physical limitations and significant symptomatic distress. Conversely, a score of 100 represents the highest possible outcome, a total absence of symptoms and no limitations in either strenuous sports activities or daily living.
All patients of both groups underwent a clinical evaluation at 6-weeks, 3-months and 6-months post-operatively to assess knee range of motion and return to daily activity life.

Radiological outcome
大体时间：Assessment of both groups was performed using weight-bearing standing radiographs to evaluate the degree of varus correction and screen for potential complications at 2-weeks (group1), 6-weeks, 3-months and 6-months postoperative.

Preoperative radiological evaluation of all patients included conventional radiography.

Assessment of group 1 was performed using weight-bearing standing radiographs to evaluate the degree of varus correction and screen for potential complications at 2-weeks, 6-weeks, 3-months and 6-months postoperative.

Assessment of group 2 was performed using weight-bearing standing radiographs and long film at 6-weeks, 3-months and 6-months postoperative.
Assessment of both groups was performed using weight-bearing standing radiographs to evaluate the degree of varus correction and screen for potential complications at 2-weeks (group1), 6-weeks, 3-months and 6-months postoperative.
