Purpose : The purpose of this paper is to analyze the clinical results after meniscal repair using meniscal arrow. Materials and Methods : Between May 1997 and Aug 1998, we repaired 22 tom menisci in 22 patients using meniscal arrows. There were nineteen males and three females with an average age of 27 years. There were longitudinal tear in 14 cases, Bucket-handle tear were 7 cases and horizontal tear was in 1 case. In 22 meniscus tears, 16 cases were associated with anterior cruciate ligament tear. Average number of meniscal arrow that was used were 2.5(ranged 1 to 4). Average follow-up period was 14.7 months(ranged 6 to 22 months). We evaluated the clinical results by the Tapper and Hoover's grading system. Results : There were excellent in 16 cases, good in 4 cases and fair in 2 cases on the clinical results. At the last follow up, the range of the motion of the knee joint were average 135 degrees(ranged 125 to 140 degrees). Mean time elapsed for meniscal repair were 25 minutes(ranged 15 to 40 minutes). Conclusion : Meniscal arrow has many advantages such as short operative time, easy fixation technique, and less neurovascular injury. We think that arthroscopic meniscal repair using meniscal arrow is effective treatment method in selected patient who have longitudinal, bucket-handle tear at the posterior hom associated with anterior cruciate ligament tear.
Arthroscopic anterior cruciate ligament(ACL) reconstruction using four-strand hamstring tendon with looping around transfixing screw in femoral tunnel requires osteointegration between the grafted tendon and bone for stability of the knee. Authors have experienced a histologic finding of osteointegration between the grafted autogenous hamstring tendon and bone in femoral tunnel after arthroscopic ACL reconstruction. A patient received arthroscopic ACL reconstruction with autogenous four strand hamstring tendon for the ACL injury. Traumatic re-rupture of mid-substance of ACL graft was developed at thirteenth week after operation. During the procedures of arthroscopic revision at fifteenth week after initial ACL reconstruction, biopsy was performed at the site of interface between grafted tendon and bone in femoral tunnel. Integration between the grafted tendon and bone was evident by demonstrating the continuity of collagen fiber between bond and tendon. This histologic finding and the low incidence of early graft failure suggest that free tendon autograft attached to bone by looping around a transfixing screw in femoral tunnel undergoes adequate osteointegration between 12 and 15 weeks after surgery and authors thought that insertion of bone chip into the femoral tunnel would accelerate osteointegration procedure.

The coverage of soft tissue defects around the knee joint or upper one third of lower leg presents a difficult challenge to the reconstructive surgeon. Various reconstructive choices are available depending on the location, size and depth of the defect. The authors present their clinical application of a medial sural artery perforator island flap as a useful alternative method for upper one third of lower leg and knee reconstruction. From 2002 to 2004, we operated total 4 patients (total 4 flaps) using the medial sural artey perforator island flap for coverage of the defect on upper one third of lower leg and knee, of 4 patients, 3 patients was men and one was woman. Average patient age was 54.6 years. The largest flap obtained was 10x8cm2. Postoperative follow up of the patients ranged from two to 33 months. In two cases, defects was located on upper one third of lower leg and in other two cases, defects were on the knee. All four cases had bone exposure open wound. In angiography, 2 cases had injured in the anterior tibial artery, 1 case had injured in the posterior tibial artery. There were no diabetes or other vascular disease. All 4 flaps were survived completely, without minor complications such as venous congestion and hematoma. Donor morbidity was restricted substantially to the donor linear scar. There were no functional impairment. As the main advantages of the medial sural perforator island flap, it ensures constant location and reliable blood supply without sacrificing any main source artery or damaging underlying muscle. This procedure is valuable extension of local flap for defect coverage with minimal functional deficit donor site and good aesthetic result on the defect. We consider it as one of the useful methods of the upper one third of lower leg and knee reconstruction.

Background: This study aims to examine the effects of sling exercise and common exercise on the pain level of various body parts. Methods: This study divided the subjects into a sling-exercise group and a common exercise group to for each group across the measurement times after practicing exercises twice per week for 8 weeks (total 16times). To compare the means of the experimental group and the control group on each variable, the ANOVA for repeated measure was used and if there was any significant difference across the measurement times, post-hoc comparisons were conducted for the difference. The T-tests for group difference according to exercise type on each of the variables showed the results as follows. Results: The results of this study suggest that there were significant difference in pain in shoulder pain, but no significant difference could be found in the Thoracic pain & Knee joint pain. There was no significant difference to distinguish between the sling exercise and the common exercise. Conclusions: Currently the sling exercise is not spread out widely in Korea, so that the recognition and studies of the sling exercise is still lacking. Hence, this study can hopefully facilitate popularity of the sling exercise and systematic prospect studies on it in the near future.
Purpose : This study shows the movements of the ankle and the foot in walking stages, and helps to diagnose and treat the problems of the ankle and the foot. The foot in human is a mean of the transportation, body support, and shock absorber. However, the slightest changes in the anatomical position can cause a significant increase of the stress and force in the ankle and the foot. The regular compressive force in the ankle of the normal person is generated by the contraction of the gastrocnemius and popliteus muscles, and transmitted to the achilles tendon. The plantar flexion about 10 degrees occurs immediately after the heel strike, getting ready for the weight acceptance. The shear force about 80 % of the body weight is generated immediately after the heel off of the mid stance phase. In those who have a problem in the ankle, the compression force at the ankle decreased to 1/3 of the body weight, and the shear force decreased, and the compressive force was reached at their maximum level earlier than the normal people. Conclusion : Analysis of the movements at the ankle and the foot in walking phase can make the effort to diagnose and treat the ankle and foot with the problems. However, the further study is necessary.
Purpose: The purpose of this study was to evaluate the mechanism of injury in the anterior cruciate ligament tears sustained in participation in soccer. Materials and methods: 50 patients whose knees were injured during playing soccer were enrolled in this study. The mean age was 27 years old, 47 were male and 3 female. 15 of them were either professional or amateur soccer players, the rest were non-professional. The injury mechanism was investigated by evaluation of the medical records or by telephone interview. Results: The injury mechanism involved contact injuries in 17 patients and non-contact in 33. 41 patients were bearing weight on the involved side at the time of injury, and 9 patients were not. In cases of contact injury, 9 of the 17 patients had sustained a valgus force to the knee, and 5 patients had varus force, 11 patients had their foot planted, and 6 did not. Among those patients with a planted foot, 3 patients were injured by the rotation of the thigh, 1 patient was injured by hyperextension, and there were no deceleration mechanism injuries. In non-contact injuries, 30 out of 33 patients had their foot planted at time of injury and only 3 patients did not. Of these 30 patients, 16 were injured by the rotation of thigh, 6 sustained a varus force on the knee joint and 5 had a valgus force, 5 were injured by hyperextension, and 2 by deceleration. 3 patients, who did not have their foot planted, were injured while kicking with the involved leg. Conclusions: For soccer players in this series, the most common mechanisms resulting in anterior cruciate ligament tears were non-contact, most often by rotation of the torso over a planted foot. In contact injuries, the most common mechanism was the application of valgus force by tackle.
During sports activity, rectus femoris muscle can be commonly injured as the quadriceps contracts forcefully to extend the knee and flex the hip, and rectus femoris muscle has a high percentage of type II muscle fibers which enable it to produce rapid forceful activity and the muscle is the only biarticular muscle of the quadriceps. Avulsion fractures by the traction of rectus femoris from the anterior inferior iliac spine in children are often reported. Rarely, complete rupture of proximal musculotendinous junction of rectus femoris muscle in adult may occurs by chronic repetitive stimulation and may mimic soft tissue neoplasm in the case of no history of antecedent trauma. However, there has been no report of acute complete rupture of origins of the rectus femoris muscle during relay race till now. So, we report a case of acute complete rupture of origins of the rectus femoris muscle occurred during relay race in middle-aged man, diagnosed by magnetic resonance image and treated by surgical repair with review of current literature.

Purpose: To investigate MRI findings of the repaired anterior cruciate ligament (ACL). Materials and Methods: Seventeen of arthroscopic ACL primary repair with sutures pull-out technique were followed for 21.4 months (range: 12 to 60 months). Stability was assessed with physical examination and KT-1000 arthrometer (MED metric, San Diego, CA) and postoperative MRI checked with time. The patients were divided into 2 groups according to the location of tear which was defined with the location of remained synovial sleeve. Group I (11 patients) comprised that the tear was located within proximal 1/3 of ACL substance and group II (6 patients) comprised below proximal 1/3. MRI findings of the repaired ACL were evaluated by its course, sharpness, thickness and signal intensity using 3 grade system and correlated with its location of tear. Results: In all cases, Lachman test and flexion-rotation drawer test were negative, pivot-shift test was less than grade 1 and the mean side-to-side difference by use of KT-1000 arthrometer was 1.4 mm (range: -1.0 to 2.5 mm). The overall continuity of the repaired ACL was well maintained in all cases. However, mild sagging was observed in 10 cases(58.8%), mild obscure contour in 6 cases (35.3%), increased thickness in 8 cases (47.1%) and slight increased signal intensity in 5 cases (29.5%). There was no statistical significance in all parameters between 2 groups. And a focal defect at the femoral attachment site in sagittal image was observed in 7 cases (41.2%) of all patients which comprised 2 cases (18.2%) of group I and 5 cases (83.3%) of group II. It was observed more frequently in group II with statistical significance (p=0.035). Conclusion: Some abnormal MRI findings such as mild sagged course, obscure contour, increased thickness and signal intensity, the focal defect at femoral attachment site could be observed even though the stability was well maintained clinically. We thought that the focal defect was affected by the location of tear of ACL.
Purpose: To report modified technique of inside-out suture in repair of tear of postero medial corner of medial meniscus. Operative technique: Arthroscope is placed through anterolateral portal. Suture hook is delivered through anteromedial portal. By rotating the suture hook, it penetrates the inner portion of the torn meniscus from femoral surface to tibial surface of the meniscus for vertically oriented suture. A PDS suture is delivered through the lumen of suture hook, and the suture hook is withdrawn. The both ends of the suture are retrieved through anteromedial portal by a retriever, either grasper or crochet hook.A Zone-specific cannula is positioned below the inferior surface of the meniscus through anterolateral portal. The Looped Needle designed by the authors is delivered through the lumen of the Zone-specific cannula. The suture end of the tibial surface is placed in the loop of the Looped Needle and pulled out to the surface of posteromedial joint line. The suture end of the femoral surface is pulled out in same manner. A transverse skin incision of 1cm size is made adjacent to pulled out suture and the suture is tied. Discussion: Even though modified inside-out suture technique requires longer operation time than conventional inside-out technique, it provides vertically oriented suture and good tissue coaptation. The authors recommend this modified inside-out suture technique to be good alternative in repairing tear of the posteromedial corner of medial meniscus.
