This study examined the effects of 8-weeks hip muscle training on the hip joint abductor muscle isokinetic strength and foot pressure distribution in elite players with chronic ankle instability (N=19). A total of 19 subjects had chronic ankle instability from at least 2 ankle sprains, and were given 8-weeks hip muscle training exercise. The hip muscle strength of the elite players with chronic ankle instability increased significantly, but the foot pressure distribution and ratio of the foot pressure distribution of the elite players with chronic ankle instability did not reach statistical significance and the ratio of the foot pressure distribution showed a similar trend. These results suggest that the strength and foot pressure distribution of the affected-side might increase to that of the unaffected-side. The 8-weeks hip muscle training helped improve the chronic ankle instability of the elite players. Therefore, the hip muscle strength and foot pressure distribution are the primary factors of a rehabilitation program on ankle sprains.

Chrisman-Snook 술식은 광범위한 절개 및 비복 신경 손상 우려 등과 함께 기술적으로 복잡하다고 여겨지고 있으나, 단비골건을 전부 희생하지 않고 전거비 인대와 종비 인대를 함께 재건하면서 동시에 이식건의 등장성을 확보할 수 있어 술 후 환자의 만족도가 비교적 높고 재발 가능성이 적은 훌륭한 술식으로 사료된다.

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.

The purpose of this study was to investigate the effects of a acute ankle mobility exercise (AE) program on the range of motion and pain levels associated with chronic ankle instability (CAI). Twenty adult women with an average score of 24 or less on both sides in the ankle instability questionnaire were selected and divided into two groups: the Ankle Mobility Exercise Program group (AE, n=10) and the control group (CON, n=10). The AE treatment involved a one-time, 20-minute exercise session for each ankle, conducted separately on the left and right ankles, to examine the response to a acute exercise. Measures of ankle instability, pain, and ankle range of motion were evaluated before and after the treatment. In the AE group, which underwent the AE program, a significant decrease in pain was observed post-AE compared to pre-AE (p<.01). In addition, an increase in dorsiflexion was observed in the AE group post-AE compared to pre-AE following the AE program(p<.05). These results suggest that a acute AE program can effectively alleviate some aspects of ankle instability by improving ankle pain and range of motion in adult women with chronic ankle instability (CAI).

Persistent instability following an acute lateral ankle sprain eventually require ligamentous reconstruction in some cases. Over 50 surgical procedures have been described to reestablish lateral ankle stability varying from direct in situ repair of the anterior talofibular ligament and the calcaneofibular ligament to augmented reconstructions with either autograft or allograft tissue. The author describes the rationale and the technique of anatomic ankle ligament reconstruction with the 4th extensor digitorum longus tendon.

본 논문에서는 만성 발목 불안정성이 있는 환자의 발목 재손상을 예방하고자 한다. 이를 위하여 발목의 안쪽 굽힙(Dorsiflexion)과 바깥쪽 굽힘(Plantarflexion)의 각도를 측정한다. 각도가 일정 범위 내에 있고 고통을 호소하지 않으면 정상으로 간주한다. 하지만 각도가 일정 범위에 못 미치고 고통을 호소하면 이상이 있는 것으로 간주하여 그에 대한 치료법(therapy)을 찾아낸다.

In an attermpt to aviod the deleterious effects of cardiopulmonary by pass such as pulmonary complication neurologic complication and renal failure off-pump CABG has been rediscovered and developed. We experienced off-pump CABG in 2 cases with unstable angina complicated with COPD and report herein the cases with review of literature.

The modified Brostrom procedure is first considered for the treatment of chronic ankle instability (CAI). Recently, ankle arthroscopy is also recommended for the treatment of concomitant intra-articular lesions during the open repair of the lateral ligaments. We arthroscopically repaired the anterior talofibular ligament with a use of bio suture anchor for CAI as well as performing the multiple drilling procedure for combined osteochondral lesion of talus. We report the cases with a review of the literature.

PURPOSE: This study examined the effects on muscle activation and ankle instability following sudden ankle inversion of the closed kinetic chain exercise using visual feedback to evaluate chronic ankle instability in adult males. METHODS: In this study, 28 subjects with chronic ankle instability were recruited and randomly divided into a closed kinetic chain exercise using a visual feedback group(n=13) and an open kinetic chain exercise group(n=15). Each group underwent 30 minutes of exercise three times a week for 8 weeks. The electromyographic(EMG) values of the rectus femoris, biceps femoris, tibialis anterior, peroneus longus, peroneus brevis, and lateral gastrocnemius muscles were measured to analyze muscle activity. The Cumberland ankle instability tool(CAIT) was used to measure ankle instability. RESULTS: Both groups showed improvements in tibialis anterior, peroneus longus and CAIT score(p<.05). In the experimental group, there were significant improvements in the rectus femoris, biceps femoris, and lateral gastrocnemius muscle activation(p<.05). CONCLUSION: The results suggest that closed kinetic chain exercise using visual feedback can be a useful treatment method for patients with chronic ankle instability.

Purpose: This study was retrospectively performed to compare the clinical outcomes of modified Brostrom procedures using the single suture anchor and the double suture anchor for chronic lateral ankle instability. Materials and Methods: Thirty-seven patients were followed up for more than 1 year after the modified Brostrom procedures using suture anchor. Single surgeon treated seventeen cases with single suture anchor and 20 cases with double suture anchor. The clinical evaluation was performed according to the Karlsson scale and Sefton grading system. Radiologic measurement of the talar tilt and anterior talar translation was performed through anterior and varus stress radiographs using Telos device. Results: The Karlsson scale had improved significantly from preoperative average of 45.2 points to 89.4 points in single suture anchor group, and from 46.4 points to 90.5 points in double suture anchor group. According to the Sefton grading system, 15 cases (88.2%) in single suture anchor group and 18 cases (90%) in double suture anchor group achieved satisfactory results. The talar tilt angle and anterior talar translation had improved significantly from preoperative average of $13.6^{\circ}$ and 8.6 mm to $5.4^{\circ}$ and 4.1 mm in single suture anchor group, from $14.1^{\circ}$ and 8.4mm to $3.9^{\circ}$ and 4 mm in double suture anchor group. Double suture anchor technique was significantly superior in postoperative talar tilt. Conclusion: Single and double suture anchor techniques produced similar clinical and functional outcomes except for talar tilt, which was significantly superior in double suture anchor group. Both modified Brostrom procedures using the single and double suture anchor appear to be effective treatment methods for chronic lateral ankle instability. Further evaluation of clinical outcomes and biomechanical studies in athletes are needed.
