Abstract

Purpose: To estimate the initial and early phase fixation power of the human bone interference screw in reconstruction of the anterior cruciate ligament with bone-patellar tendon-bone allograft. Materials and Methods: The results of twenty eight knees of reconstruction with bone-patellar tendon-bone allograft were analysed in 6 weeks, 12 weeks, 6 months and one year following operation. Physical examination including Lachman test, flexion rotation drawer test and jerk test were performed. The KT-1000 measurement was performed at the same time. In Lachman test 0 $\~$2mm anterior displacement of the tibia was considered normal. The KT-1000 measurement of normal side was compared with operation side and the difference of the two was recorded. The MRI was checked at final follow-up. Results: All but one knee showed normal in physical examination. The failed case showed proximal migration of the graft due to insufficient number of interference screw fixation in widened tibial tunnel. Conclusions: The human cortical bone interference screw showed sufficient initial and early phase fixation power in reconstruction of the anterior cruciate ligament.

목적: 동종골-슬개건-골을이용한전방십자인대재건술시인간골간섭나사못의초기및조기고정력을알아보려고하였다. 대상및방법 : 동종골-슬개건-골을이용한전방십자인대재건술을28 슬관절에대해수술후6주, 12주, 6개월, 1년에추적조사하였다. Lachman test, flexion rotation drawer test, jerk test등의이학적검사를시행하였고KT-1000 측정을동시에시행하여경골의전방전위정도를측정하였다. Lachman test는 0$\~$2mm 전방전위까지를정상으로하였고KT-1000 측정은정상측과비교하여 2mm 이내는정상으로하였다. 마지막검사시M RI를시행하였다. 결과: 단일예를제외하고는모두이학적검사와KT-1000 측정상정상범위에속하였다. 실패한일례는수술소견상이식물이경골터널에서의근위전위되었으며이는넓어진터널을감안하지않고단하나의간섭나사못을사용한기술적실수로평가되었다. 결론: 인간골골피간섭나사못은전방십자인대의재건술을시행하는데충분한초기및조기고정력을보여주었다.
