Summary
The mini trivector approach improves minimally invasive total knee replacement for knees with significant deformity or stiffness. This technique allows better joint exposure by reducing extensor mechanism tension.
Area of Science:
- Orthopedic Surgery
- Minimally Invasive Procedures
- Total Knee Arthroplasty
Background:
- Minimally invasive total knee arthroplasty (TKA) faces challenges with major knee deformity or stiffness.
- Current methods require excessive soft-tissue tension for adequate joint exposure in complex cases.
Purpose of the Study:
- To introduce and describe the "mini trivector approach" for TKA.
- To expand indications for minimally or less invasive TKA in challenging knee conditions.
Main Methods:
- The mini trivector approach involves a limited double snip of the VMO and quadriceps tendon.
- This technique aims to reduce tension on the extensor mechanism.
- Facilitates easier patellar verticalization and improved joint visualization.
Main Results:
- The mini trivector approach enhances joint exposure in cases previously unsuitable for less invasive TKA.
- It effectively reduces tension on the extensor mechanism.
- Allows for successful application of minimally invasive techniques in complex knee deformities and stiffness.
Conclusions:
- The mini trivector approach is a viable and effective technique for total knee replacement.
- It broadens the applicability of minimally invasive TKA to a wider range of patients, including those with significant knee issues.
- This method offers improved exposure and reduced extensor mechanism tension.
