Hypothesis
Does prior high tibial osteotomy affect the results and complications of total knee arthroplasty?
Conclusion
Total knee arthroplasty after high tibial osteotomy is technically more challenging, but the clinical outcomes are similar to those of primary knee arthroplasty.
Supporting Evidence
- Patients with prior high tibial osteotomy had more perioperative blood loss.
- Mid-term functional scores were less favorable for the index group but not significantly different.
- The tibial slope was significantly decreased after high tibial osteotomy.
Takeaway
If someone has surgery on their knee to fix a problem and later needs a new knee, it can be trickier, but the results are about the same as if they had never had the first surgery.
Methodology
Matched case control study comparing outcomes of total knee arthroplasty in patients with and without prior high tibial osteotomy.
Potential Biases
Selection bias may exist due to the non-randomized nature of the study.
Limitations
The study cannot address unknown or immeasurable prognostic factors.
Participant Demographics
Median age of participants was 60 years, with a BMI of 31.3 kg/m2; 10 women and 2 men in the index group.
