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 had a preoperative Tegner activity score of five or more.
- 50 out of 63 patients (79.4%) returned to high-impact sports at their presymptomatic level after surgery.
- The mean time to return to sports was 8.0 months.
- Statistical analysis identified postoperative mTFA >3° valgus, opening gap >10 mm, and KL grade 4 as significant risk factors for poor outcomes.
Takeaway
This study looked at patients who had knee surgery to help them get back to sports, and found that many could return, but some factors could make it harder.
Methodology
The study included 63 patients who underwent unilateral high tibial osteotomy and evaluated their outcomes using KOOS and IKDC scores, along with radiological assessments.
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.
