From 1989 to 1994, authors have reconstructed the posterior cruciate ligament(PCL) in 51 knees with an autogenous central one-third of the patellar tendon by transtibial two tunnel technique, but there were not a few cases of unfavorable results. So from January 1995, we have reconstructed the PCL deficient knees by "modified tibial inlay technique" to avoid the grafted tendon abrasion at the posterior opening of the tibial tunnel(killer turn). Purpose of this study was to compare the results of two surgical techniques and what its advantages and disadvantages are. We could follow up 39 cases of transtibial two tunnel techique group(group A) more than one year, average being 23.7 months and 21 cases of modified tibial inlay technique group(group B) more than 12 months, average being 14.7 months. The clinical results were evaluated by the OAK knee scoring system ($M{\ddot{u}}ller$'s criteria) and the posteror stress roentgenography (push view) with Telos stress device compared with the uninjured knees. The arthroscopic second-look findings were also evaluated. In group A : The $M{\ddot{u}}ller$'s knee score was average 80.1 points, the posteror displacement in push view was average 4.4mm at the last follow up. There were 17 cases(44%) of unfavorable results which showed unstable posterior displacement more than 4mm compared with the uninjured knee in push view. Among the 19 cases of arthroscopic second look examinations, nearly normal PCL appearances of the grafted tendons were noted only in 9 cases(47%). In group B : The $M{\ddot{u}}ller$'s knee score was average 86.7 points, the posterior displacemnet in push view was average 3.6mm at the last follow up. There were 5 cases(23.8%) of unfavorable results which showed unstable posterior displacement more than 4mm compared with the uninjured knee in push view but 4 out of 5 cases showed 6mm posterior displacement in push views. Among the 7 cases of arthroscopic second-look examinations, 6 cases(86%) showed nearly normal PCL appearances of the grafted tendons. In modified tibial inlay technique of PCL reconstruction, it was easier to pull out the BPTB and in cases of remained laxed meniscofemoral ligament it was easier to preserve the remained structures than transtibial two tunnel technique. We expect the "modified tibial inlay technique" may solve the problem of grafted patellar tendon abrasion at the posterior orifice of tibial tunnel and may contribute to the successful PCL reconstruction.

목적: 전방십자인대 단일 다발 재건술에서 경경골 터널과 전내측 삽입구를 이용한 대퇴골 터널의 기울기를 방사선학적으로 비교하였다. 대상 및 방법: 2006년 1월부터 2009년 12월까지 시행한 전방십자인대 재건술 132예 중 단일 다발 재건술의 대퇴골 터널 형성에 경경골 술기를 이용한 30예와 전내측 삽입구를 이용한 재건술 20예를 전후방, 과간 절흔상 및 측면 방사선 사진을 통해 관상면 및 시상면에서의 골 터널 기울기를 측정하였다. 결과: 관상면에서 대퇴 터널이 대퇴과간 관절면의 연결선과 이루는 각도는 경경골 술기의 경우 평균 $71^{\circ}$ (범위: $65^{\circ}{\sim}77^{\circ}$), 전내측 접근법은 평균 $51^{\circ}$ (범위: $39^{\circ}{\sim}60^{\circ}$)였으며 두 군간의 유의한 차이를 보였다(P<0.05). 관상면에서 경골 터널이 관절면과 이루는 각은 경경골 술기에서 평균 $55.7^{\circ}$ (범위: $49^{\circ}{\sim}68^{\circ}$), 전내측 접근법은 평균 $52.1^{\circ}$ (범위: $37^{\circ}{\sim}58^{\circ}$)를 보였다. 시상면상경골 터널이 관절면과 이루는 각은 경경골 술기에서 $62.6^{\circ}{\pm}5.4$, 전내측 접근법은 $60.1^{\circ}{\pm}2.7$로 유사한 값을 보였고, 대퇴 터널이 대퇴 후방 피질골의 연장선과 이루는 각은 경경골 술기에서 $22.7^{\circ}{\pm}7.8$, 전내측 접근법은 $30.2^{\circ}{\pm}6.9$로 통계적으로 유의하였다(P<0.05). 결론: 전방십자인대 단일 다발 재건술에서 전내측 삽입구를 이용한 대퇴터널 형성은 경경골 술기에 비해 관상면에서 보다 수평적이었고 후방 피질골로 부터의 기울기 증가를 보였다.
