Arthroscopic partial meniscectomy: a long-term follow-up.
1Department of Orthopedic Surgery, University Hospital, Arhus, Denmark.
Summary
Arthroscopic meniscus resection can lead to long-term knee issues, with a high reoperation rate. However, bucket handle tears showed better outcomes, with less pain and fewer degenerative changes after 8.5 years.
Area of Science:
- Orthopedics
- Sports Medicine
- Knee Surgery
Background:
- Arthroscopic meniscus resection is a common procedure for meniscal tears.
- Long-term outcomes and risk factors for degenerative changes following this surgery require further clarification.
Purpose of the Study:
- To evaluate the long-term clinical and radiological consequences of arthroscopic meniscus resection.
- To identify risk factors associated with poor outcomes after the procedure.
Main Methods:
- A follow-up study involving 136 patients who underwent unilateral arthroscopic meniscus resection.
- Clinical interviews, physical examinations, and radiological assessments were performed.
- Average follow-up duration was 8.5 years.
Main Results:
- The overall reoperation rate was 22.8%, with bucket handle tears having the lowest rate (13%).
- Patients with bucket handle tears reported less post-exercise pain.
- 53% of operated knees showed degenerative changes (Fairbanks criteria); malalignment (valgus < 4° or > 10°) was a significant risk factor.
Conclusions:
- Arthroscopic meniscus resection has significant long-term consequences, including degenerative changes.
- Bucket handle tears appear to have better long-term prognoses compared to other meniscal lesions.
- Knee malalignment is a critical risk factor for developing osteoarthritis after meniscus resection.
