Summary
Biodegradable polyurethane meniscus scaffold implantation (BPMSI) reduced pain and improved knee function within 36 weeks. While muscle strength recovered, knee stability did not significantly improve post-procedure.
Area of Science:
- Orthopedic surgery
- Biomaterials science
- Sports medicine
Background:
- Irreparable medial meniscus defects pose challenges for knee function and stability.
- Biodegradable polyurethane meniscus scaffolds offer a potential solution for meniscus regeneration.
Purpose of the Study:
- To evaluate the impact of biodegradable polyurethane meniscus scaffold implantation (BPMSI) on muscle strength and balance.
- To compare outcomes with the healthy contralateral knee in patients with irreparable medial meniscus defects.
Main Methods:
- Prospective observational case-cohort study involving arthroscopic BPMSI for irreparable medial meniscus defects.
- Assessment of pain (VAS), function (KOOS, Lysholm score), muscle strength (peak torque), and knee stability at 12, 24, and 36 weeks post-surgery.
Main Results:
- Significant reduction in pain and improvement in range of motion, Lysholm, and KOOS scores by 36 weeks.
- Concentric quadriceps and hamstring peak torque, and peak torque-to-body weight ratios showed improvement.
- Knee stability indexes (anterior-posterior, medial-lateral, overall) demonstrated a slight, non-significant improvement.
Conclusions:
- BPMSI effectively reduces pain and enhances knee function at 36 weeks post-implantation.
- Muscle strength largely recovered, but knee joint stability did not show significant improvement within the study period.
