Poster 242: Predictors of the Ten-Year Patient-Reported Outcome Measures After Collagen Meniscus Implant (CMI) for Partial Meniscus Deficiency

Objectives: Collagen Meniscus Implant (CMI) is considered an effective procedure for reducing knee pain and improving function after previous meniscectomy. Nevertheless, the current knowledge regarding clinical results of CMI are limited to small case series at short- mid-term follow-up studies. The goal present study was evaluate outcomes, reoperations, failures a minimum 10 years follow-up. Methods: Consecutive patients who underwernt single institution were screened elegibility. Inclusion criteria (1) Medial or Lateral CMI, (2) Isolated combined with ACL reconstruction, osteotomy cartilage treatment, (3) between 15 years. Demographics surgical details obtained via chart review. Patients asked if they satisfied evaluated Lysholm score, Knee injury Osteoarthritis Outcome Score (KOOS), visual analog scale (VAS) pain, Tegner score final Survival analysis performed Kaplan-Meier curve, scores analyzed based on Patient Acceptable Symptom State (PASS). Results: A total 92 (mean age, 42.8 years) included in analysis. significant improvement all reported preoperative evaluation last chondropaty outerbridge grade ≥III associated significantly overall lower while timing from meniscectomy implant ≥5 determined more rest KOOS quality life. Overall, 25% did not achieved PASS percentage variable 19% (KOOS Pain) 40% Symptoms) subscales. Chondropaty higher Risk achieving subscales, age surgery ≥45 resulted risk subscale.

Finally, 80% Conclusions: provided satisfactory terms function, symptoms, sports life 60% than still compared evaluation. status time have shown impact negatively >45 less pain.
