The Korean Journal of Sports Medicine.2012;30(2):148-151. doi:10.5763/kjsm.2012.30.2.148

Knee arthroscopy is generally considered a very safe operation with very high success rates. Few reported cases of complications arising from only arthroscopic partial meniscectomy include deep vein thrombosis and pulmonary embolism. In this study, we present the case of a 44-year-old female patient with complications of deep vein thrombosis arising after undergoing an arthroscopic partial meniscectomy. Eight days post-operation, the patient presented with pain and swelling of the lower limb and inguinal area of the same side as the operation and was diagnosed by computed tomography scan with deep vein thrombosis. Apart from obesity, the patient presented with no other risk factors for deep vein thrombosis. The patient was given heparin treatment and discharged once her symptoms were relieved.

The Korean Journal of Sports Medicine.2012;30(2):144-147. doi:10.5763/kjsm.2012.30.2.144

We performed modified Z-plasty (N-plasty) in the patients with snapping hip syndrome arising from the iliotibial band whose pain and clicking sensation persisted despite conservative treatments. We analyzed clinical results to evaluate the effectiveness of this new technique. Among 51 patients (65 cases) who still felt pain and reported clicking sensation during daily life despite hospitalization for at least 2 months from January 1999 to November 2011, we evaluated a total of 32 patients (37 cases) who underwent N-plasty and followed up for more than 6 months. All patients were male whose average age was 24 years. Initial symptoms developed an average of 10 months before hospital visit. Surgery was defined success by postoperative 6 months at which time the patient could be able to carry on with daily life and to exercise without clicking sensation and pain, and defined failure when either clicking sensation or pain was present. We observed that the posterior portion of the iliotibial band was thickened by an average of 8.4 mm. Tenotomy of the iliotibial band lengthened the band by an average of 23mm and narrowed the width of the iliotibial band anterior to posterior. Success was in 33 cases (89%) after surgery. Failure was observed in 4 cases. Three were improved after resurgery and 1 was treated conservatively. We found that N-plasty performed in external type snapping hip patients was an effective method yielding a high success rate.

Eun Kuk KIM ; Tae Gyu KIM

The Korean Journal of Sports Medicine.2012;30(2):137-143. doi:10.5763/kjsm.2012.30.2.137

The healthcare for elite athletes has the potential to create many ethical issues for sports practitioners. And the relationship between a sports practitioner and an athlete differs significantly from the traditional doctor-patient relationship. However, there has been little discussion of them to date. To investigate the ethical awareness and concerns in sports medicine field, we surveyed the responses of Korean medical team to a questionnaire during the Summer Olympic Games 2012. The questionnaire was developed to access a wide-range of common ethical issues in sports medicine; conflict of interests, confidentiality, pediatric athletes, performance-enhancing substances, infectious disease, innovative therapies, medical advertising. Twenty-nine out of 32 sports practitioners responded to the questionnaire (90.6%). Respondents identified many ethical matters concerning the unique characteristics of athletes-as-patients in sports medicine. This study has started the process of identifying contemporary ethical problems with regard to the sports medicine, and there should be further studies dealing with these problems.

The Korean Journal of Sports Medicine.2012;30(2):130-136. doi:10.5763/kjsm.2012.30.2.130

Recently, rising curiosity on remnant preservation technique of anterior cruciate ligament (ACL) reconstruction, there is much interested in being and distribution of the mechanoreceptor of ACL. So, we performed histologic analyzing and mapping of sensory nerve fiber of the human ACL in this study. Total of 20 anterior cruciate ligaments were obtained from total knee replacement. Each ACL samples was divided into seven specimens; tibial insertion site, mid transitional site, femoral insertion site, and in between the sites, and total of 140 tissue samples were stained with hematoxylin-eosin and immunohistochemical, and observed with light microscope. Five hundred thirty-four fine neuroparticle structures, Ruffini corpuscles, and free nerve endings were observed in 20 ACL samples. The mean of fibers observed were 1.88, 1.71, 1.15, 1.08, 1.15, 1.55, and 1.82, respectively from tibial insertional site to femoral insertional site. With immunohistochemical stain, S-100 protein was strong positive at nerve cells, but was weak positive or negative at neurofilament. Mapping of sensory nerve distribution were done based on the results. We identified the mechanoreceptor of the human ACL using optical and immunohistochemical methods and mapped the histologic distribution of that.

The Korean Journal of Sports Medicine.2012;30(2):123-129. doi:10.5763/kjsm.2012.30.2.123

The shoulder injury was resulted from muscle imbalance between acceleration and deceleration during the throwing. The agonist-antagonist muscle strength relationship for throwing was formerly described as functional ratios of eccentric external rotator to concentric internal rotator moments and eccentric internal rotator to concentric external rotator moments. The purpose of this study was to measure the ratio of concentric and eccentric strength of the shoulder rotators by isokinetic muscle performance in Korean throwing college athletes for descriptive data. On 10 dominant shoulders of asymptomatic throwing college athletes applying Cybex II isokinetic dynamometer, concentric and eccentric muscle strength of the rotators were measured at the speed of 90degrees/s, 180degrees/s, 240degrees/s. Maximal torque ratio of the eccentric strength of the external rotator against the concentric strength of the internal rotator was 1.25, 1.13, 1.21 at the each speed. The functional external eccentric-to-internal concentric ratio was similar with previous published studies. There was no significant difference between each speed. Eccentric strength of the external rotator was higher than concentric strength of the internal rotator during internal and external rotation at all speeds. This functional assessment of strength testing that reflected the importance of eccentric external rotation strength for the dynamic shoulder joint stability during the throwing. Therefore, the increase of the eccentric strength of the external rotator would be helpful to prevent the shoulder injury and to treat for rehabilitation of injured shoulder.

Sung Hoon KANG ; Young Hyeon BAE

The Korean Journal of Sports Medicine.2012;30(2):116-122. doi:10.5763/kjsm.2012.30.2.116

The purpose of this study was to evaluate the efficacy of a aquatic exercise program (AEP) compared with a land exercise program (LEP) in children with spastic cerebral palsy on motor function and balance. Thirty children with spastic cerebral palsy receiving edgewise treatment were randomly assigned to two groups, a AEP and a LEP. AEP and LEP were applied to two groups of children with spastic cerebral palsy for 30 minutes, three times a week for 8 weeks. Range of motion (ROM) of ankle dorsi flexion, Modified Ashworth Scale (MAS) while ankle dorsi flexed, Pediatric Berg's Balance Scale (PBS), and Gross Motor Function Measure (GMFM) were used for pre and post comparison. There were significant differences of ROM while ankle dorsi flexed, PBS and GMFM between pre and post treatment in all the two groups (p<0.05). But as a measure of MAS while ankle dorsi flexed did not show a significant differences. And the was significant difference in the amount of change of the ROM while ankle dorsi flexion between the two groups (p<0.05). The results would suggest that both of the exercise program are equally effective.

Kwang Mee KIM ; Joung Kyue HAN ; Young YI ; Churl Hong CHUN

The Korean Journal of Sports Medicine.2012;30(2):100-109. doi:10.5763/kjsm.2012.30.2.100

The purpose of remnant preserving technique in anterior cruciate ligament (ACL) reconstruction is to preserve mechanoreceptor and accelerate revascularization. In this study, we compared a group who underwent remnant preserving technique using Achilles tendon allograft with the other group of conventional ACL reconstruction in terms of proprioception, kinematic analysis, knee strength test and dynamic postural stability. Twenty-four patients were followed up for longer than 12 months after ACL reconstruction. They were separated into two groups; remnant preserving group (n=12) and non-remnant group (n=12). Proprioception test was conducted through joint position sense (JPS) and threshold to detection of passive motion. The remnant preserving group showed significantly less difference from the normal side than the non-remnant group. In kinematic analysis, there was statistically significant difference in peak flexion angle during the swing phase. However the 60degrees JPS, knee strength test, performance capacity test and dynamic postural stability did not showed the significant difference. Remnant preserving technique of ACL reconstruction was meaningful in preserving proprioception and the result showed akin to the unaffected gait.

The Korean Journal of Sports Medicine.2012;30(2):92-99. doi:10.5763/kjsm.2012.30.2.92

The purposes of this study were basic data collection and evaluation of the risk factors regarding rowing injuries through an epidemiologic study. We performed a questionnaire survey from rowers who participated in the 91th Annual Sports Festival in Jinju, Gyeongnam, in October 2010. 145 rowers (male: 84, female: 61) responded to the survey. The t-test was used for comparisons for the type of injury, age, and gender. The multiple linear regression analysis and the logistic regression analysis was used for the evaluation of risk factors. Overall, 100 (69.0%) rowers had a history of injury. The incidence of overuse injuries was significantly higher than the incidence of traumatic injuries (2.07+/-2.59/rower vs. 1.46+/-2.08/rower, p=0.027). The incidence of injuries for the adult group was significantly higher than those in the youth group (4.42+/-4.45/rower vs. 2.61+/-3.63/rower, p=0.008). There was no significant difference between males and females (3.85+/-4.33/rower vs. 3.08+/-3.87/rower, p=0.275). Also, the incidence of cross-training related injury was significantly higher in traumatic injuries rather than in overuse injuries (0.92+/-1.54/rower vs. 0.5+/-1.07/rower, p=0.008). In addition, rowing injuries were more related with overuse injuries. Risk factors regarding overall rowing injuries were training time, and training using stairs. Traumatic injuries were related with diverse cross-training and time spent cross-training. Therefore, in order to reduce the incidence of rowing injuries, time and the number of cross-training sessions should be reduced. Moreover, highly risky training such as using stairs should be replaced with other low risk training methods.

The Korean Journal of Sports Medicine.2012;30(2):85-91. doi:10.5763/kjsm.2012.30.2.85

The aim of this study was to examine the effect of phase I cardiac rehabilitation program (CRP) on physical capacity in patients with coronary artery bypass graft (CABG). Eighty seven patients who underwent CABG in our hospital were enrolled on the study. Among them, excluding 17 during the study, the results of 70 patients were included in the final data. Subjects were classified into two groups according to the participation in the phase I CRP; participation group (n=35) and non-participation group (n=35). The CR was executed for the participation group until patients' discharge. The variables including resting heart rate (RHR), oxygen saturation, walking distance in 6 minutes, and forced expiration amount were measured at initial phase, discharge and follow-up at 1 month after discharge. From the data, descriptive statistics (mean, standard deviation) were calculated, and differences in each variable before, during, after the treatment and between groups were tested using repeated measure analysis of variance using SPSS ver. 18.0 statistics program for Window. For the effects and results with a statistical significance, post-hoc test was made using t-test. There was statistically significant difference (p<0.05) in the RHR and the walking distance in 6 minutes. While there was no significant difference in the oxygen saturation and the maximum expiration amount. As conclusion, the Phase I CRP after CABG showed a effect on the significant improvement of physical capacity by decreasing the RHR and increasing the walking distance in 6 minutes, exerting a positive influence on the recovery after the CABG operation.
