Meniscal lesions and chronic anterior cruciate ligament deficiency. Meniscal tears occurring before and after reconstruction.
We examined the menisci in 47 patients at the time of anterior cruciate ligament reconstruction. Twenty-one patients had abnormal menisci at a mean of 34 months after injury, but there was no difference between the Lysholm scores of patients with intact or damaged menisci. Eleven patients had a new meniscal injury between reconstruction and review at a mean of six years later; only 15 patients had both menisci intact nine years after injury. If pivot shift had been cured, the incidence of meniscal injury was reduced, but remained higher than normal. If pivot shift returned after reconstruction there was a significantly higher incidence of meniscal injury. Meniscal lesions appear to be the result of instability and not the cause.
