Arthroscopic meniscal repairs have been found to deliver good outcomes at long-term follow-up, according to a study presented at the American Orthopaedic Society for Sports Medicine´s annual meeting.

For the purpose of the study, scientists gathered and analysed data from 206 patients who had experienced meniscal repairs. Repair failures were defined by subsequent meniscal surgery (either re-repair or meniscectomy) or if the knee was converted to total knee arthroplasty (TKA). Researchers also took note of demographic data, SF12 physical component scores and mental component scores, Lysholm score, WOMAC score, IKDC score, the Tegner activity scale and patient satisfaction. The average follow-up was around 14 years.

Results showed that 64 knees were considered failures. Out of those, 47 were with meniscectomies, 14 had meniscal re-repairs and three were converted to TKAs. The average SF-12 physical component and mental component scores were 54 and the average Lysholm value, as indicated in final follow-up, was 86. The average WOMAC value was 6 and average IKDC value was 73, said Karen Briggs, MBA, MPH, during her presentation. The results also showed that the median Tegner activity scale value was six and the median patient satisfaction score was nine, on a scale of one to ten.

Most patients did not have subsequent surgery until five years or more after their initial repair, Briggs pointed out.

It was also interesting to note that older patients did not experience an increase in repair failure, Briggs concluded.
