Hypothesis

The study hypothesized that opening-wedge high tibial osteotomy would achieve a high rate of return to high-impact sports in active patients.

Conclusion

Postoperative factors such as mTFA greater than 3° valgus, an opening gap greater than 10 mm, and KL grade 4 were identified as risk factors that impair the return to high-impact sports.

Supporting Evidence

  • 63 patients were included in the study, all of whom were highly active before surgery.
  • 50 out of 63 patients (79.4%) returned to high-impact sports at their presymptomatic level.
  • The mean time to return to sports was 8.0 months after surgery.
  • Significant improvements were observed in KOOS and IKDC scores postoperatively.
  • Factors such as postoperative mTFA >3° valgus were significantly associated with poor outcomes.

Takeaway

The study looked at patients who had knee surgery and found that most were able to return to their favorite sports, but some factors could make it harder for them.

Methodology

The study included 63 patients who underwent unilateral high tibial osteotomy and evaluated their return to sports using KOOS and IKDC scores.

Potential Biases

Selection bias may exist due to the specific cohort of highly active patients included in the study.

Limitations

The study was retrospective, had a small sample size, and included two different surgical procedures, which may introduce bias.

Participant Demographics

The study included 63 patients, 44 males and 19 females, with a mean age of 55.8 years.
