The anterior cruciate ligament is a very important structure for functional anterior stability of knee joint. If a knee with complete ACL rupture is not treated properly, progressive knee instability will occur. Therefrom the reconstruction of ACL is required to correct deformity and to prevent secondary degenerative osteoarthritis and the injury of meniscus caused by anterior instability.
We treated 48 cases of isolated chronic ACL rupture with ligament reconstruction between Jan. 1989 land Dec. 1994. We reconstructed ACL using patellar tendon augmented with and without Kennedy-ligament augmentation device(LAD). All operations
were performed arthroscopically. The 38 ones of 48 cases were followed up over 2 years. Twenty-seven of 33 (82%) performed by nonaugmented procedures and eleven of 15(73%) by LAD augmented reconstructions were reviewed.
@ES The clinical result were as follows;
@EN 1) The average age of the ACL kreconstruction using patellar tendon without ALD (Group 1) was 26 years old and one of the ACL reconstruction using patellar tendon with LAD (Group 2) was 29 years old.
2) For the increment of Lysholm knee score, the group 1 had average 37.8 points and the grjoup 2 had average 234.4 points.
3) According to Lysholm knee score on pain, swelling and stair-climbing, the group 1 got better results than the group 2. On instability, the group 2 got better ones than the group 1.
4) Using the K-T 1000 arthrometer, when 20lbs(89N) anterior drawer force was applied, the preoperative average anterior displacement of tibia kin affected side was 5,8mm more than normal side in group 1, and was 6.0mm more in group 2.
5) using the K-T 1000 arthrometer, when 20lbs (89N) anterior drawer force was applied, the postoperative average anterior displacement of the tibia in affected side was 2.3 mm more than normal side in group 1, and was 1.2 mm more in group 2.
6) Postoperative ROM(range of motion) of knees was nearly normal and there was no extension lag in any cases.
7) Postoperaitve complication was occurred in one case of group 1; extra-articular deep infection and in one case of group 2; synovitis.
It was concluded that there was no difference between the two groups in a clinical comparative results.
