Meniscal lesions treated with suture: a follow-up study using survival analysis
1Department of Orthopedics and Traumatology, University of Bergen, Haukeland Hospital, Norway.
Summary
Meniscal refixation using arthroscopic outside-in suture techniques showed a 50% survival rate at 5 years, with smaller posterior lesions healing better. Reoperation for rerupture occurred in 39% of patients.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Knee Surgery
Background:
- Meniscal tears are common knee injuries.
- Surgical repair (refixation) aims to restore meniscus function.
- Arthroscopic techniques offer minimally invasive options.
Purpose of the Study:
- To evaluate the long-term outcomes of arthroscopic outside-in meniscal refixation.
- To identify factors influencing the success of meniscal repair.
Main Methods:
- Retrospective review of 57 patients undergoing arthroscopic outside-in meniscal refixation with PDS sutures.
- Follow-up evaluation of 51 patients over a median of 1.5 years.
- Kaplan-Meier survival analysis to assess cumulative survival rates.
Main Results:
- A 50% cumulative survival rate at 5 years was observed.
- Twenty patients (39%) required reoperation due to meniscal rerupture.
- Smaller posterior meniscal lesions demonstrated better healing outcomes compared to larger lesions.
Conclusions:
- Arthroscopic outside-in meniscal refixation has a moderate long-term survival rate.
- Meniscal rerupture remains a significant complication.
- Lesion size, particularly posterior location, impacts healing success.
