Hypothesis
The study hypothesized that opening-wedge high tibial osteotomy would achieve a high rate of return to high-impact sports and that there would be prognostic factors affecting postoperative functional recovery.
Conclusion
Postoperative mTFA greater than 3° valgus, an opening gap greater than 10 mm, and KL grade 4 were identified as risk factors impairing the return to high-impact sports.
Supporting Evidence
- 50 out of 63 patients (79.4%) returned to high-impact sports activities at the presymptomatic level.
- The mean time to return to sports was 8.0 months.
- Significant improvements were observed in KOOS and IKDC scores postoperatively.
- Postoperative mTFA >3° valgus, opening gap >10 mm, and KL grade 4 were identified as significant risk factors.
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 functional recovery using KOOS and IKDC scores, along with radiological assessments.
Potential Biases
Selection bias may have occurred due to the specific cohort of motivated patients.
Limitations
The study was retrospective, had a small sample size, varied follow-up periods, and included two different surgical procedures.
Participant Demographics
The study included 63 patients, 44 males and 19 females, with a mean age of 55.8 years.
