Summary

Return to sports after H-CWHTO surgery, which is indicated when arthropathic changes have progressed, may be expected to be adequate.

Abstract

Purpose

There are many reports on return to sports after knee osteotomy, and the rate of return to sports after open wedge high tibial osteotomy (OWHTO) is particularly high. On the other hand, hybrid CWHTO (H-CWHTO), a variant of closed wedge high tibial osteotomy (CWHTO) indicated for more advanced knee osteoarthritis, has shown good results, but there are no reports on return to sports after surgery. Therefore, we report here the return to sports at 2 years after surgery.

Methods

In a retrospective cohort study, patients underwent radiographic evaluation before and after surgery and were asked questions using a questionnaire at 2 years postoperatively.

Results

Thirty-one patients with 39 knees were included in the study, with a preoperative Tegner activity score (all median values below) of 3.9, K-L grade 2.6, %MA 18.1%, mMPTA 83°, and age 63.1 years. Twenty-two patients (71%) continued to play sports 2 years after surgery as they did before surgery.

Conclusion

Return to sports after H-CWHTO surgery, which is indicated when arthropathic changes have progressed, may be expected to be adequate.
