  • Objectives : This study was performed to evaluate the clinical effect of acupuncture on microtraumatic injuries of the knee joint. Methods : Among the outpatients with knee joint pain who visited to Department of Acupuncture & Moxibustion, National Medical Center from February 2000 to September 2000, we selected 15 cases that showed normal finding in both X-ray and neurological examination, and that were categorized into microtraumatic injuries by the physical examination based on the Cyriax's orthopedic medicine. During acupuncture therapy, the patients were ordered to move involved side actively. The effect was assessed through questionnaires of CNRS(Cincinnati Knee Rating System). Results : We investigated 11 female and 4 male patients. The most common distribution of age was 30's(40%). The most commom duration of symtoms was from 3 to 5 months(40%). The most common microtraumatic injury was pes anserinus bursitis(33.3%), and followed by iliotibial band friction syndrome(20%), and patellar tendinitis(20%). In the CNRS, the mean number of before treatment was 60.6 and after was 66.5. 10 cases among the 15 patients were improved(66.6%). Conclusions : These results suggest that the acupuncture therapy combined with active movements of involved side was effective treatment modality on microtraumatic injuries of the knee joint.

  • Objectives The objective of this study is to report the evidence that continuous passive motion (CPM) therapy combined with Korean Medicine is effective for knee injuries. Methods We searched 2 Korean medical electronic databases, and 2 Chinese electronic databases to find randomized controlled clinical trials (RCTs) that treat knee injuries with Korean Medicine combined with CPM therapy. We selected studies by screening. We extracted data from selected RCTs, and analyzed RCTs by using Cochrane's Risk of bias criteria. Results 386 studies are searched, and 7 RCTs are selected. According to the study, several kinds of Korean Medicine such as hydrotherapy, decoction, acupuncture, moxibustion, and manual therapy are used with CPM therapy for the knee joint postoperative rehabilitation. We found the encouraging evidence that Korean Medicine and CPM combined therapy is more effective than single CPM therapy by alleviating pain, increasing range of motion, and improving knee function, etc. However, the risk of bias in most RCTs was judged to be uncertain. Conclusions Combination of Korean Medicine and CPM therapy can compensate the defect of single CPM therapy, and promotes the recovery of knee joint function.

  • In volleyball, the most common injuries are anterior cruciate ligament (ACL) tears. For this reason, volleyball players frequently use knee brace as prophylactic and rehabilitation measures. The purpose of the study was to investigate the effects of knee brace on anterior cruciate ligament injuries risk factors during spike take off in female volleyball players. Fifteen female volleyball players were recruited and performed randomly spike take off with and without knee brace. Kinematics and ground reaction data were collected to estimate the anterior cruciate ligament injuries risk factors. The ACL risk factors are knee maximum flexion angle, thigh maximum adduction angle, thigh maximum internal rotation angle, shank maximum abduction angle, shank maximum external rotation angle, knee maximum extension moment and knee maximum abduction moment. Data were analyzed with paired samples t-test with Bonfferoni collection. Female volleyball players with knee brace had no significant results in knee maximum flexion angle, thigh maximum adduction angle, thigh maximum internal rotation angle, shank maximum abduction angle and shank maximum external rotation angle compare to without knee brace. Female volleyball players, however, with knee brace showed more reduced knee maximum extension moment and knee maximal abduction moment than without knee brace. In conclusion, Female volleyball players with knee brace reduced anterior cruciate ligament stress.

  • The ACL(Anterior cruciate ligament) is the smallest of the four main ligaments of the knee, but it is the primary stabilizer. Injuries have a tendency to occur when the foot is firmly planted and the knee is twisted. Any sports that requires acceleration, change of direction and deceleration can increase the chances of suffering an ACL tear. The incidence of severe knee sprains that involve the ACL are at an all-time high. Since 1980, the number of these injuries have increased at least three-fold. Although the rate of increase has been much less dramatic since the middle 1980s, even the ultra-modem releasable ski binding has not been able to start reducing the incidence of ACL injuries. An ACL injury prevention program developed for downhill skiers by the Vermont Safety Research group emphasized increasing awareness of situations that can potentially result in an ACL injury and pre-planning strategies if events, leading to these situations, begin to fall in place. As part of the above study by Ettlinger et al., an educational prevent program was developed to teach these principles and thus reduce the rate of serious knee injuries. Four thousand instructors and patrol at 20 ski resorts who received the training had a 62% decline in serious knee injuries compared to a similar group that did not receive this training. Whenever you fall, try not to fully straighten your legs. Don't try to get up until you've stopped sliding(unless you are try to avoid an obstacle or other skier). When you're down, stay down. And don't land on your hand. So, if you feel yourself falling: arms forward, ski plates together, hands over knee. Then you will be able to save your ACL.

  • Objective: This study aimed to investigate the influence of landing foot orientations on biomechanics of knee joint in order to identify vulnerable positions to non-contact knee injuries during single-legged landing. Method: Seventeen men (age: $20.5{\pm}1.1 years$, height: $175.2{\pm}6.4cm$, weight: $68.8{\pm}5.8kg$) performed single-leg drop landings repeatedly with three different landing foot orientations. They were defined as toe-in (TI) $30^{\circ}$ adduction, neutral (N, neutral), and toe-out (TO) $30^{\circ}$ abduction positions. Results: The downward phase time of TI was significantly shorter than those of N and TO. The flexion and valgus angle of N was greater than those of TI and TO at the moment of foot contact. At the instance of maximum knee flexion, N showed the largest flexion angle, and TO position had the largest varus and external rotation angles. Regarding ground reaction force (GRF) at the moment of foot contact, TO showed the forward GRF, while others showed the backward GRF. TI indicated significantly larger mediolateral GRF than others. As for the maximum knee joint force and joint moment, the main effect of different foot positions was not significant. Conclusion: TI and TO might be vulnerable positions to knee injuries because both conditions might induce combined loadings to knee joint. TI had the highest mediolateral GRF with a shortest foot contact time, and TO had induced a large external rotation angle during downward phase and the peak forward GRF at the moment of foot contact. Conclusively, N is the preferred landing foot orientation to prevent non-contact knee injuries.

  • Recently, the incidence of anterior cruciate ligament injury is rapidly increasing because many young Korean are actively participating in sports activities including basketball, skiing and soccer. Sometimes acute ACL injuries arc misdiagnosed as sprain because of pain and muscle spasm. An accurate physical examination and careful history taking are very important to diagnose the ACL injuries. Therefore author described the skill of history taking and the technique of physical examination to diagnose ACL injuries. The most sensitive test is the Lachman's test, which is performed with the knee in 200 of flexion, the femur stabilized with full flexed examiner's knee placed behind patient's distal thigh and one hand of examiner, and the proximal tibia grasped with the other. The pivot shift test is a passive motion test that attempts to subluxate the tibia anteriorly, then have it reduce rapidly. The pivot shift test is very sensitive test to diagnose the chronic ACL injuries.

  • Objective: The purpose of this study was to investigate the possibility of injuries and the types of movement related to damage by body parts, and to prepare for prevention of injuries and development of a training program. Method: For this study, the experiment was conducted according to levels of 60 percentages (ST) and 85 percentages (MA) and 10 subjects from the Korean elite national weightlifting team were included. Furthermore, we analyzed joint moment and muscle activation pattern with three-dimensional video analysis. Ground reaction force and EMG analyses were performed to measure the factors related to injuries and motion. Results: Knee reinjuries such as anterior cruciate ligament damage caused by deterioration of the control ability for the forward movement function of the tibia based on the movement of the biceps femoris when the rectus femoris is activated with the powerful last-pull movement. In particular, athletes with previous or current injuries should perceive a careful contiguity of the ratio of the biceps femoris to the rectus femoris. This shows that athletes can exert five times greater force than the injury threshold in contrast to the inversion moment of the ankle, which is actively performed for a powerful last pull motion and is positively considered in terms of intentional motion. It is activated by excessive adduction and internal rotation moment to avoid excessive abduction and external rotation of the knee at lockout motion. It is an injury risk to muscles and ligaments, causing large adduction moment and internal rotation moment at the knee. Adduction moment in the elbow joint increased to higher than the injury threshold at ST (60% level) in the lockout phase. Hence, all athletes are indicated to be at a high risk of injury of the elbow adductor muscle. Lockout motion is similar to the "high five" posture, and repetitive training in this motion increases the likelihood of injuries because of occurrence of strong internal rotation and adduction of the shoulder. Training volume of lockout motion has to be considered when developing a training program. Conclusion: The important factors related to injury at snatch include B/R rate, muscles to activate the adduction moment and internal rotation moment at the elbow joint in the lockout phase, and muscles to activate the internal rotation moment at the shoulder joint in the lockout phase.

  • Purpose: We investigated the natural history of acute, isolated posterior cruciate ligament injuries treated conservatively. Materials and Methods: Between February 1999 and October 2006, we evaluated retrospectively the results of acute, isolated posterior cruciate ligament injuries treated conservatively. The subjects consisted of 21 patients. At initial and follow up visits physical examination, $KT-2000^{TM}$ arthrometer and MRI were performed to assess improvement on the knee stability and continuity of the posterior cruciate ligament. IKDC (International Knee Documentation Committee) knee scoring and quadriceps muscle strength were also checked in all population. Comparing the results of initial and follow up examinations we assessed the natural history of acute, isolated posterior cruciate ligament injuries treated conservatively. The mean follow up period was 22.7 months. Results: The posterior drawer test showed 14 cases of Grade I, 6 cases of Grade II and 1 case of Grade III progressing 18 cases of Grade I and 3 cases of Grade II. The mean difference of 5.7mm by $KT-2000^{TM}$ arthrometer was changed Into 2.7mm and the continuity of posterior cruciate ligament initially checked by 48.1% on MRI increased to 69.7%. The mean quadriceps muscle strength was grade 'Good' and mean IKDC knee score was nearly grade 'A'. Conclusion: Our study suggests that patients with acute, isolated posterior cruciate ligament injuries treated conservatively may get good clinical outcomes on clinical situation and MRI.
