Prospective randomized study. Compare two techniques for high tibial osteotomy (HTO) for treatment of medial knee osteoarthritis. Opening wedge osteotomy using Puddu plate vs Closing wedge osteotomy using cramp fixation. We will compare functional results and patient satisfaction with repetitive evaluations from preoperatively to 2 years postoperatively.
Determination of the time course of patient-relevant functional outcome and the time course of Range of Motion (ROM) following HTO. Comparison of the Opening wedge and Closing wedge methods. Time-dependent improvement in functional outcome following High tibial Osteotomy. Medial opening wedge vs Lateral closing wedge. A two-year prospective randomized study involving 70 patients. In a prospective randomized study, we plan to include 70 patients aged 30-60 years operated with valgus high tibial osteotomy. 2 groups: 35 opening wedge, and 35 closing wedge osteotomies. Data are collected by independent investigators (physiotherapists) preoperatively and at 3 months, 6 months, 1 year, and 2 years postoperatively. Knee injury and Osteoarthritis Outcome Score (KOOS) and ROM are determined at all follow-ups.

Kne injury and Osteoarthritis Outcome Score (KOOS)
The change in KOOS score are followed at several time points the first 2 years. Patients will be evaluated with KOOS, 3 months, 6 months, 1 year and 2 years postoperatively.
Time frame: 2 years postoperataively
Range of motion (ROM)
The change in ROM are followed at several time points the first 2 years. ROM will be measured 3 months, 6 months, 1 year and 2 years postoperatively.
Time frame: 2 years postoperatively
