The effect of meniscal status on knee stability and function after anterior cruciate ligament reconstruction.

The purpose of this study was to examine the relationship of meniscal status at the time of anterior cruciate ligament (ACL) reconstruction with the ultimate function and stability of the knee joint. Seventy-one patients were studied prospectively following bone-patellar tendon-bone ACL reconstruction. Subjects were divided into six subgroups relative to the integrity (intact, partial meniscectomy, complete meniscectomy) of the two menisci. After a minimum of 2 years of follow-up (range 2-4.1 years), 56 subjects were available for subjective, objective, and radiographic assessment. Meniscal status at the time of ACL reconstruction proved to have no significant bearing on the ultimate stability of the knee. However, individuals who had undergone meniscal excision reported subjective complaints and activity limitations more commonly than those with intact menisci (p < 0.05). Radiographic changes also were more common in the meniscectomized subset.
