Investigators found significant improvements in scores from preoperative values to 2-year follow-up in patients who received a lateral collagen meniscus implant for the treatment of irreparable lateral meniscus tears or partial lateral meniscal defects and linked high BMI, chronic injuries and concomitant surgery with worse results.

Researchers prospectively evaluated 43 patients after they underwent treatment of partial lateral meniscal defects using the collagen meniscus implant.  For 6 months, all patients received the same rehabilitation treatment until they returned to tolerable activity levels. They were followed up at 6 months, 12 months and 24 months after the procedure. During the follow-ups, researchers evaluated patients using Lysholm, Tegner Activity Scale and VAS scores as well as a functional and satisfaction questionnaire. Researchers also recorded any serious adverse events and reoperations.

After 6 months, the investigators found functional improvements for the group. After 12 months, knee swelling and strenuous activities reach satisfactory results, according to researchers.

Highest pain ratings from strenuous activity, routine activity and rest improved significantly from preoperatively to the 2-year follow-up. There were 58% of patients who were able to return to similar activity levels prior to injury, with 95% of patients satisfied with their results. Serious adverse events were observed in 6% of patients, according to researchers. ‒ by Monica Jaramillo
