Summary
This study evaluated all-inside meniscal repair devices in cadaver knees. While 83% of Rapid Loc devices were correctly placed, popliteus tendon and MCL entrapment occurred.
Area of Science:
- Orthopedic surgery
- Biomedical engineering
- Sports medicine
Background:
- Meniscal tears are common knee injuries.
- All-inside meniscal repair devices offer potential advantages over traditional methods.
- Evaluating the safety and efficacy of new surgical devices is crucial.
Purpose of the Study:
- To assess the accuracy and safety of the Rapid Loc all-inside meniscal repair device.
- To identify potential complications associated with Rapid Loc device placement in a cadaver model.
Main Methods:
- Arthroscopic insertion of Rapid Loc devices into posterior menisci of 8 fresh-frozen cadaveric knees.
- Placement of 48 devices at 5- to 7-mm intervals.
- Dissection to evaluate device location and identify any complications.
Main Results:
- 83.3% (40 of 48) of Rapid Loc devices were inserted correctly.
- No issues with fixation loss on the meniscal periphery were observed.
- Complications included popliteus tendon entrapment (3 of 8 knees) and superficial medial collateral ligament entrapment (2 of 16 meniscus repairs).
Conclusions:
- The Rapid Loc device demonstrates a high rate of correct placement in a cadaver model.
- Potential risks include entrapment of surrounding soft tissues, such as the popliteus tendon and MCL.
- Further investigation is warranted to refine surgical technique and minimize complications.
