Hypothesis
What factors influence the results of manipulation under anaesthesia (MUA) for improving knee flexion after total knee arthroplasty (TKA)?
Conclusion
Manipulation under anaesthesia is effective for improving range of motion after TKA, but its effectiveness varies based on the number of previous surgeries and pre-MUA flexion.
Supporting Evidence
- The prevalence of stiffness after TKA was found to be 4.54%.
- Patients with two or more previous surgeries had significantly worse results after MUA.
- Stiffer knees with flexion below 70° showed worse results in absolute flexion but better gain in flexion after MUA.
Takeaway
If your knee is stiff after surgery, a special procedure can help you bend it better, but it works best if you haven't had too many other surgeries before.
Methodology
The study analyzed data from patients who underwent manipulation under anaesthesia to treat stiffness after total knee arthroplasty, focusing on factors like BMI and previous surgeries.
Potential Biases
Potential biases include the retrospective nature of the study and unmeasured factors affecting outcomes.
Limitations
The sample size may be too small for meaningful analysis, and the follow-up period of six weeks might be too short to draw lasting conclusions.
Participant Demographics
The average age of participants was 64.15 years, with 82.1% female and 17.9% male.
