Title : A study on functional recovery: Medial parapatellar versus Midvastus approaches in knee Arthroplasty
Abstract:
Total knee arthroplasty (TKA) is widely regarded as a highly successful joint replacement procedure, with many patients experiencing significant functional improvement post-surgery. The parapatellar approach is most commonly employed, although the midvastus approach is recognized as a viable alternative. However, it remains unclear which technique offers superior patient outcomes.
This study employed a double-blind, prospective, observational, and comparative methodology to assess the differences between these two surgical approaches. The findings revealed that the midvastus approach (MV) offers several advantages over the medial parapatellar approach (MPP) during the early postoperative period. Specifically, patients in the midvastus group were able to perform straight leg raises sooner and exhibited less extensor lag compared to those in the medial parapatellar group. Furthermore, the Knee Society Knee Score and functional scores were notably higher in the midvastus group immediately after surgery.
In conclusion, the midvastus approach, which minimizes disruption to the extensor mechanism and the peripatellar plexus of vessels, appears to alleviate pain and enhance range of motion during the initial rehabilitation phase following TKA.
