The Effect of Body Mass Index on Short-term Results of HTO

Summary

The knee joint plays a major role in weight transmission of the body in day-to-day activities. The biomechanics of the knee and malalignment in lower limb anatomy are major risk factors for chronic knee pain, leaving Total Knee Arthroplasty (TKA) as the best and most successful option for patients with end-stage osteoarthritis (OA)

Eligibility

Inclusion Criteria:

* No serious underlying medical disease
* Conservative treatment is ineffective and there is a willingness for surgery
* X-ray shows degeneration limited to the medial joint space (Ahlback grade ≥ grade II)
* Knee flexion range of motion \> 90°, varus deformity \< 15°, flexion contracture \< 5°.
* Clinical examination shows intact anterior cruciate ligament and collateral ligament, tenderness point is limited to the medial joint space, and the lateral compartment and patellofemoral joint are intact.

Exclusion Criteria:

* knee osteoarthritis caused by infection, blood-related or autoimmune diseases.
