Brief summary

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.

Detailed description

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.

Design outcomes

Primary

MeasureTime frameDescription
Kne injury and Osteoarthritis Outcome Score (KOOS)2 years postoperataivelyThe 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.

Secondary

MeasureTime frameDescription
Range of motion (ROM)2 years postoperativelyThe 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.

Other

MeasureTime frameDescription
Oxford knee score2 yearsThe change in Oxford score are followed at several time points the first 2 years. Patients will be evaluated with Oxford knee score, 3 months, 6 months, 1 year and 2 years postoperatively.
Lysholm score2 years postoperativelyThe change in Lysholm score are followed at several time points the first 2 years. Patients will be evaluated with Lysholm, 3 months, 6 months, 1 year and 2 years postoperatively.
UCLA activity scale2 years postoperativelyThe change in UCLA scale are followed at several time points the first 2 years. Patients will be evaluated with UCLA activity scale, 3 months, 6 months, 1 year and 2 years postoperatively.
Tegner Activity Score2 years postoperativelyThe change in Tegner score are followed at several time points the first 2 years. Patients will be evaluated with Tegner score, 3 months, 6 months, 1 year and 2 years postoperatively.
