Summary
The patella inversion method provides adequate exposure for revision total knee arthroplasty (TKA) without damaging the extensor mechanism. This technique was safely used in 95% of revision TKA cases, avoiding patellar tendon avulsion.
Area of Science:
- Orthopedic Surgery
- Arthroplasty
Background:
- Adequate surgical exposure is crucial for successful revision total knee arthroplasty (TKA).
- Traditional extensile exposure techniques can compromise the extensor mechanism.
Purpose of the Study:
- To evaluate the efficacy and safety of the patella inversion method for surgical exposure in revision TKA.
- To determine if this method provides sufficient exposure without violating the extensor mechanism.
Main Methods:
- A retrospective review of 420 consecutive revision TKA cases performed between 1987 and 1999.
- The patella inversion exposure technique was utilized in 95% (397) of these cases.
- No attempt was made to evert the patella during the procedure.
Main Results:
- The patella inversion method provided adequate exposure for the majority of revision TKA procedures.
- No instances of patellar tendon avulsion were reported in the series.
- This technique successfully avoided violation of the extensor mechanism in most patients.
Conclusions:
- The patella inversion method is a safe and effective approach for achieving adequate exposure in revision TKA.
- It offers a viable alternative to more invasive extensile techniques, preserving the integrity of the extensor mechanism.
