Summary
Pes anserinus transfer surgery showed a high rate of knee instability and radiographic changes in long-term follow-up. While many patients experienced symptom improvement, a significant number still had functional limitations.
Area of Science:
- Orthopedic surgery
- Knee biomechanics
- Sports medicine
Background:
- Pes anserinus transfer is a surgical procedure used for various knee conditions.
- Long-term outcomes and potential complications require thorough evaluation.
Purpose of the Study:
- To assess the long-term functional outcomes and radiographic changes following pes anserinus transfer.
- To investigate the incidence of rotatory instability after this procedure.
Main Methods:
- A retrospective evaluation of forty-eight patients (fifty knees) who underwent pes anserinus transfer.
- Average follow-up period of nine years post-operation.
- Assessment of rotatory instability and radiographic changes.
Main Results:
- High incidence of anteromedial and anterolateral rotatory instability observed.
- Significant roentgenographic changes were present in 54% of cases at follow-up.
- Only 38% of patients reported no functional limitations.
Conclusions:
- Pes anserinus transfer can lead to long-term rotatory instability and degenerative changes in the knee.
- While symptomatic improvement is possible, functional deficits often persist after surgery.
