Summary
Minimally invasive surgery-total knee arthroplasty (MIS-TKA) uses a small incision for knee replacement. This article details the MIS-TKA technique, focusing on the mini midvastus approach.
Area of Science:
- Orthopedic Surgery
- Surgical Techniques
Background:
- Minimally invasive surgery-total knee arthroplasty (MIS-TKA) involves a skin incision of 5 inches or less.
- A mini midvastus approach is utilized to minimize soft tissue trauma.
Purpose of the Study:
- To describe the technique for minimally invasive surgery-total knee arthroplasty (MIS-TKA).
Main Methods:
- The procedure involves a lateral subluxation of the patella without eversion.
- Specialized instrumentation, including cutting guides, sizers, and retractors, is essential.
Main Results:
- MIS-TKA presents technical challenges requiring advanced instrumentation.
- Further research, including prospective randomized controlled trials, is needed.
Conclusions:
- The mini midvastus approach for MIS-TKA aims to reduce patient morbidity.
- Outcomes of MIS-TKA should be compared to traditional total knee arthroplasty.
