Abstract

We reviewed the post-reconstructive results and complications of arthroscopic anterior cruciate ligament reconsbuction using the patellar bone-tendon-bone autograft in 91 patients who underwent the index surgery at least one year ago. The changes of Lysholm knee score, limitation of motion, instability of the reconstructed ACL, musc)e strength, presence of anterior knee pain and other complications were evaluated at final fol- low-up(mean, 2.6 year). The results were as follows. 1. The mean Lysholm knee score was 65.5+-15.5 preoperatively and improved to 88.5+-7.4 postoperatively(p<0.05), 2. Of all, nine(9.9%) complained anterior knee pain. 3. Three patients(3.3%) showed limited range of motion. 4. Five(3.5%) showed instability of reconstructed ACL during the followup. Two were caused by trauma. Ln other three, no definite causes were found. 5. In 23 patients, cybex isokinetic thigh muscle strength test was perfornied preoperatively and at post-up. One year. The strength of quadriceps of the operated side at the angular velocity of 60 degrees per second showed mean 41.7% deficit of the normal side at postoperative one year. 6. Other complications were one case of chronic click sound in motion, and one case of the fracture which occurred at the autograft donor site of the proximal tibia.
