Hypothesis
The sub-vastus approach is significantly superior to the standard medial parapatellar approach in terms of short and long term knee function.
Conclusion
The study aims to determine which surgical approach leads to better knee function after total knee replacement.
Supporting Evidence
- Previous studies showed that the sub-vastus approach resulted in quicker recovery times and less pain.
- Patients using the sub-vastus approach had better quadriceps strength in earlier follow-ups.
- Long-term follow-up is needed to confirm if short-term benefits lead to better long-term outcomes.
Takeaway
This study is trying to find out if one way of doing knee surgery is better than another way.
Methodology
Patients undergoing primary total knee arthroplasty will be randomly assigned to either the sub-vastus or medial parapatellar approach, with outcomes measured at multiple time points.
Potential Biases
The previous studies were not truly randomised and had issues with blinding.
Limitations
Previous studies had small sample sizes and short follow-up periods, which may affect the validity of their findings.
Participant Demographics
Patients undergoing primary bi or tri compartmental knee replacement.
