Anterior cruciate ligament is a very important structiure for stablility of knee joint. Because injured aterior cruciatre ligamentedled to the instahbility of knee, tear of meniscus, degenerative arthritis and decreased life activity, varios
operative
treatment have been described for the treatment of chronic anterior cruciate ligament insufficiency.
We analyzed the 31 case who had taken the reconstruction surtgery of anterior cruciate ligament using bone-patelar tendone-bone graft under arthroscopy from Septeber 1988 to October 1992,. The average follow up period was 26 months. The results
were as follows:
1. Of the 31 Knees, 21(69%) knees were caused by sport injury. 28(90%) patients were male and average age was 24.9 years old.
2. Duration of the interval from injuries to operation was average 27.4 months. In the physical examination for instability in preoperative period, 29(94%) knees were positive in anterior drawer test, 31(100%) knees Lachmannm´s test and 27(87%)
knees
in pivot shift test. Sin the last follow up, 27*87%) knees were negative in anterior drawer test, 19(61%) knees negative and 6(20%) knees trace in Lachmann´s test test and 27(87%) knees negative in pivot shift test.
24(77%) knees were combined with meniscal injury. 4 knees were treated by arthroscopic meniscorrhpy and 17 knees by arthroscopic meniscectomy.
4. The patients were evaluated by Marshall´s knee rating scale.
15(81%) of 31 Knees were estimated as excellent or good result. Average Marshalol scoring scale was 33.8 point at preoperative and 45.9 point at the last follow up.
Average Lysholm knee scoring scale was 74 point at preoperative and 94 point at the last follow up. According to KT-1000 arthrometer, 25(81%) of 31 knees were estimated below 2mm by side to side difforence with manual maximum values at last
follow
up.
