  • Purpose: This study was performed to evaluate the diagnostic usefulness of ankle stress radiograph for evaluation of chronic lateral ankle instability. Materials and Methods: Among patients undergoing the modified-Brostrom procedure, 42 cases with complete rupture of the anterior talofibular ligament were enrolled in this study. Sixty Korean adults (120 cases) were recruited as the control group. Radiologic measurement of talar tilt and anterior talar translation was performed through stress radiographs using Telos device. We obtained the normal range of Korean adults, and used as a standard value for judgment of mechanical instability. We analyzed the sensitivity, specificity, positive and negative prediction value of ankle stress radiograph. Results: On ankle stress radiograph, normal range of talar tilt angle and anterior talar translation was below $8.3^{\circ}$, below 7.6mm. Talar tilt angle on varus stress radiograph showed 57% of sensitivity, 97% of specificity, 89% of positive and 86% of negative prediction value. Anterior talar translation on anterior drawer stress radiograph showed 69% of sensitivity, 97% of specificity, 91% of positive and 90% of negative prediction value. Conclusion: Ankle stress radiograph had a good specificity, positive and negative prediction value for the evaluation of mechanical instability. However it underestimated the mechanical instability of ankle joint. It must be remembered that normal stress radiograph does not exclude ankle instability.

  • 전방십자인대의 일차수복술이나 재건술후에 장기간의 비체중부하가 필요한지를 결정하기 위해서 일차수복술을 시행한 96례와 재건술을 시행한 82례등 총 178례를 대상으로 술후 체중부하시기에따라 두군으로 나누어 비교분석 하였다. 모든 례에서 술후 보조기를 착용하였고 120례에서는 술후 첫6주간 점차적으로 관절운동범위를 증가를 시키고 다음 6주간은 완전운동범위 회복상태에서 유지후 술후 12주에 체중부하를 허용하였으며 나머지 58례에서 술후 완전신전상태에서 즉시 체중부하를 시켜서 정기적으로 Lachman검사, KT 2000을 이용하여 불안정성여부를 관찰하였다. 평균 추시기간은 4.2년(2년$\~$6년)이었고 불안정성에 대한 평가는 AMA 분류에 따랐다. 최종추시상 모든환자에서 1+이상의 불안정성은 발견되지 않았으며 술후 12주에 체중부하를 한군에서 1a+가 104례$(86.7\%)$, 1b+군이 16례$(13.3\%)$로 관찰되고 즉시 체중부하를 한 군에서 1a+가 51례$(87.9\%)$, 1b+가 7례$(12.1\%)$에서 보였으나 통계적으로 의미있는 차이는 없었다(P>0.05). 본연구의 결과로 전방십자인대 일차수복술이나 재건술후 신전보조기를 착용시키고 즉시 보행을 시키는 것이 술후 슬관절의 불안정성에 영향을 주지 않으며 안전한 재활방법으로 생각된다.

  • Posterolateral instability of the knee occurs more commonly in association with an injury to anterior and posterior cruciate ligament and combined injuries are severe injuries that result in significant functional instability and articular cartilage degeneration. Reconstruction of the anterior and posterior cruciate ligament without an appropriate treatment of posterolateral corner injury result in failure of the reconstructed cruciate ligaments. Meticulous physical examinations, imaging studies, lower limb alignment and gait pattern should be evaluated. Acute grade III isolated or combined injury of the posterolateral corner is best treated within three weeks by direct repair, or augumentation, or reconstruction. The appropriate surgical method or combined methods are selected among the several methods of posterior and posterolateal reconstruction, and all injuried posterolateral and cruciate ligament structures are anatomically reconstructed simultaneously or by stages. If a varus alignment and varus thrust is disclosed in chronic posterolateral instability of knee, soft tissue reconstructions laterally are highly unlikely to be able to correct tile problem. It is appropriate that valgus osteotomy should be done before soft tissue reconstruction and reevaluate the posterolateral instability about 6 months later.

Results of Anterior Cruciate Ligament Reconstruction with Unicondylar Arthroplasty for Medial Compartment Knee Osteoarthritis combined with Anterior Instability (전방 불안정성과 동반된 슬관절 내측 구획 진행성 관절염환자에서 전방십자인대 재건술 및 인공 관절 부분 치환술의 결과 - 3예 보고 -)

  • Three cases who had medial compartment osteoarthritis of the knee (Kellgrene-Laurence grade 3 and Outerbridge grade 4) and anterior instability of the knee due to rupture of the anterior cruciate ligament in relative young ages underwent staged anterior cruciate ligament reconstruction followed by medial unicondylar arthroplasty in 2 cases and simultaneous anterior cruciate ligament reconstruction and unicondylar arthroplasty. We evaluated clinical results some kinds of preoperative and postoperative International Knee Documentation Committee (IKDC), Lysholm score and last follow-up hospital for special surgery (HSS), knee society score (KSS). We consider that medial unicondylar arthroplasty with staged or simultaneous anterior cruciate ligament reconstruction is very good option of the treatment for the anterior instability and pain from advanced arthritis.
