Researchers evaluated 235 patients from the Multicenter Orthopaedic Outcomes Network who underwent both unilateral primary ACL reconstructions and concurrent meniscal repair between 2002 and 2004. Of the meniscal repairs, 154 were medial, 72 were lateral and nine underwent both.
Validated patient-oriented outcome data (KOOS, WOMAC) scores, Marx activity scores and IKDC scores were recorded at two and six years follow-up. Failure of meniscal repairs was determined by subsequent ipsilateral repair.
“This represents the largest cohort combining meniscus repair and ACL reconstruction follow-up for a minimum of six years,” Robert W. Westermann, M.D., said.
Overall, 86 percent of meniscal repairs were successful at six-year follow-up; of these, 86.4 percent were medial meniscal repair, 86.1 percent were lateral meniscal repairs and 77.8 percent were in cases where both were repaired, according to Westermann.
Of the 33 repair failures, nine (27.3 percent) were related to revision ACL surgery. On average, medial meniscal repairs failed sooner than lateral repairs (2.1 years vs. 3.7 years).
KOOS Symptoms, KOOS Pain, KOOS KRQOL, WOMAC Pain, and IKDC values all improved significantly when comparing baseline scores to six-year follow-up, according to Westermann. Marx Activity levels gradually declined from time of injury to six-year follow-up.
