Summary
Bioabsorbable meniscus repair devices can cause issues if they don't fully resorb. Removing undissolved materials relieved symptoms in three patients, highlighting a need for improved implant design.
Area of Science:
- Orthopedic surgery
- Biomaterials science
Background:
- Bioabsorbable meniscus repair devices offer advantages like quick application and lower neurovascular risk.
- The Biostinger device is one such implant used for meniscus repair.
Observation:
- Three patients with persistent meniscus tear symptoms after Biostinger repair underwent second-look arthroscopy.
- In all cases, the meniscus had healed, but some Biostinger material remained unresorbed.
Findings:
- Removal of the unresorbed bioabsorbable material led to symptom resolution.
- Delayed resorption of meniscus implants can lead to intra-articular inflammation (synovitis) and cartilage damage (chondral lesions).
Implications:
- Meniscus implant designers and researchers must address the issue of late resorption.
- Further research is needed to develop bioabsorbable materials with predictable resorption profiles for meniscus repair.
