Purpose: The purpose of this study is to find out the normal results in ankle on varus stress, valgus stress, and anterior draw stress in young men in korea. This would be helpful as the basic data of measuring of ankle instability for operational indication. Materials and Methods: Varus and Valgus stress anteroposterior radiographs and Anterior drawing stress lateral radiographs of 600 normal ankles were reviewed. First, A line parallel was drawn parallel to the articular surface of the distal tibia, and another line was drawn parallel to the articular surface of the talus on anteroposterior radiographs. The interior angle that subtended by these two lines was measured. Second, the reference point is located at the posterior border of the tibia, and the shortest distance from this point to the proximal posterior articular surface of the talus is measured. Results: There were 300 males and 600 ankles. The mean age overall was 21 years (19-22 years) old. The mean length of ankle on anterior draw stress was $5.54{\pm}3.33\;mm$. The mean a interior angle of ankle on varus stress was $0^{\circ}-8.93^{\circ}$, and on valgus stress $0^{\circ}-7.78^{\circ}$. Conclusion: We can consider for operational indication at over the 8.87 mm on anterior draw stress, over the $8.93^{\circ}$ on varus stress, and over the $7.78^{\circ}$ on valgus.

Purpose: Anterior drawer and varus stress radiographs are commonly to diagnose chronic lateral ankle instability. We compared the preoperative stress radiographs with the intraoperative radiographs under anesthesia to determine the accuracy and efficacy of stress radiographs in an outpatient clinical environment. Materials and Methods: Data was collected from patients who underwent a modified $Brostr{\ddot{o}}m$ operation for painful chronic unilateral lateral ankle instability between January 2014 and June 2016. Subjects were divided into three groups-complete tear, partial tear, and instability without rupture-according to the status of preoperative MRI findings of the anterior talofibular ligament. The anterior drawer and varus stress radiographs were taken preoperatively and intraoperatively under anesthesia. Results: Ninety-six patients, with a mean age of 29.63 years, were enrolled. There were 39, 46, and 11 patients in the complete tear, partial tear, and instability without rupture groups, respectively. On the anterior drawer and varus stress radiographs of the affected limb, talar anterior translation and varus tilting were significantly increased by 2.56 mm and $2.0^{\circ}$. The gaps between the unaffected limbs were also increased by 2.47 mm and $1.32^{\circ}$ after anesthesia. Although the stress radiographs were taken under anesthesia, the results were often smaller than the diagnostic value. Conclusion: Stress radiographs for painful chronic lateral ankle instability taken at the outpatient clinic might be inaccurate for diagnosis.

The purpose of the study was to evaluation of the knee lateral collateral ligament (LCL) stability of normal males and females in twenties by using digital telometer. The volunteer subjects agreed the research goal and were 31 normal adults(16 male: $21.1{\pm}1.5$ years, 15 female: $21.2{\pm}1.2$ years) who have not got any illness regarding their knee. X-ray images were taken varus stress on medial femorotibial joint space using by digital telometer, and grade of pain was surveyed. We measured the joint space width (JSW) in the digital radiology. As a result, the JSW of male group were $5.60{\pm}0.76$ mm and JSW of female group were $5.05{\pm}0.55$ mm (p=0.022) on the neutral state of the knee. Based on the result of varus stress on the knee, female group showed much widen than male group but it was not significant difference (p>0.05). When increased varus stress on the knee, all groups were felt pain from 17 daN to 19 daN. The result could be valuable when the varus stress on the LCL by using the digital telometer.

Purpose: The purpose of this study was to describe the method of dynamic sonographic measurements in the evaluation of the MCL injury of the knee joint while applying valgus and varus stress. Materials and Methods: Seven cases of MCL injury from January to April of 2008 was used for the study. For the evaluation of the medial instability, sonography was used immediately after injury, 6 weeks and 12 weeks after conservative treatment with limited motion brace. The length between the foot of the medial femoral epicondyle and the most proximal point of the tibial cortex was measured in 30 degrees flexion with valgus and varus stress of the knee joint. Results: The foot of the medial epicondyle and the starting point of the proximal tibial cortex underneath the round portion of the articular cartilage were always able to be seen on ultrasonography, even in varus and valgus stress with gravity in 30 degrees flexion of the knee joint. The results of measurements were always constant. Conclusion: Sonography can be used in evaluation of medial instability under the dynamic valgus and varus stress of the knee joint without further injury.

Purpose: Anterior drawer and varus stress test are commonly used for radiologic evaluation of chronic lateral ankle instability. However, there are controversies regarding the method of measurement and the normal value. This study was performed to investigate radiologic normal values in normal Korean adults and to analyze differences by age and gender. Materials and Methods: Sixty Korean adults were recruited and divided in three groups (20 in their twenties, 20 in their thirties, 20 in their forties). There were 10 males and 10 females in each group. The selection criteria were no history of ankle injury and no evidence of instability on physical examination. Radiologic measurement of varus talar tilt and anterior talar translation were performed through anterior and varus stress radiographs using Telos device (150N force). The measurement was repeated twice by three researchers, and intraobserver reproducibility and interobserver reliability were analyzed. The average talar tilt and anterior talar translation were obtained. Results: Talar tilt and anterior talar translation on ankle stress radiographs had good intraobserver reproducibility and interobserver reliability. Talar tilt was average $3.7^{\circ}$ and $5.1^{\circ}$ in male and female of twenties of age, $3.9^{\circ}$ and $4.8^{\circ}$ in their thirties, $3.4^{\circ}$ and $4.5^{\circ}$ in their forties. Anterior talar translation was average 3.5 mm and 4.2 mm in their twenties, 4.1 mm and 3.8 mm in their thirties, 3.6 mm and 4.1 mm in their forties. There was no significant difference in talar tilt and anterior talar translation by age. However, there was significant difference in talar tilt by gender. Conclusion: Normal range of talar tilt angle in Korean adults was below $8.3^{\circ}$, and normal range of anterior talar translation was below 7.6 mm. It seems to be able to serve as a good reference for radiologic evaluation and for treatment of chronic lateral ankle instability.

Purpose: This study was performed to evaluate clinical and radiographical results of treatment of chronic lateral ankle instability with modified Brostrom procedure. Materials and Methods: This is a retrospective study of 22 cases in 22 patients treated with modified $Brostr{\ddot{o}}m$ procedure under the diagnosis of chronic lateral ankle instability from May 2000 to August 2004. Average age was 32.3 years. Average follow-up period was 23 months. Preoperative and postoperative radiographs of ankle anteroposterior view, lateral view and varus stress view were analyzed. The clinical evaluation was performed according to the Americal Orthopaedic Foot and Ankle Society scales. Results: After the modified $Brostr{\ddot{o}}m$ procedure, Americal Orthopaedic Foot and Ankle Society scales score was improved by average 28 points. Among the 22 cases, 13 cases were excellent, 3 cases good, 4 cases fair, and 2 cases poor with satisfaction of 73%. Five cases had intermittent ankle pain of whom 3 cases had difficulty during competitive sports activity. Lateral tilting of talus improved by average 5.4 degrees on varus stress view. Conclusions: The modified $Brostr{\ddot{o}}m$ procedure is one of the most effective methods for treating of chronic lateral ankle instability.

Purpose: The purpose of this study is to evaluate the surgical results of modified $Brostr{\ddot{o}}m$ procedure for chronic lateral ankle instability and to assess whether or not associated injuries may affect postoperative satisfaction. Materials and Methods: Twenty- four patients with chronic lateral ankle instability were evaluated retrospectively from August 1998 to March 2002. Average age was 29.3 years. All patients were performed pre & postoperative ankle anteroposterior and lateral view, stress anterior drawer and varus test using Telos device, MRI and intraoperative arthroscopic evaluations before ligament reconstruction. Results: Of the 24 cases, 23 cases was improved more than average 12 points on AOFAS scales. On modified scales of Hamilton, 3 excellent, 20 good, 1 fair results. On stress view, average 2.2 mm difference was improved on anterior drawer test and average 1.7 degree on varus test. Associated injuries were 8 osteochondral defects, 4 anterior impingements, 2 loose bodies, 2 os subfibulare, 2 os submalleolare and 2 partial ruptures of peroneus brevis. 8 cases with no associated injuries rated excellent or good. Conclusion: The modified $Brostr{\ddot{o}}m$ procedure is believed to be an effective and successful method for chronic lateral ankle instability that didn't respond to conservative treatment. Because associated injuries in chronic lateral ankle instability may affect postoperative satisfaction, appropriate detection and treatment may need for postoperative satisfaction.

Subacute Ankle Sprain patients, 3 tests have been acknowledge for diagnostic precision and thus most commonly used to test their soft tissues, muscles, and ligaments: ankle stress-valgus test, anterior-draw test, and MRI scan. Although not much different from the rest two in its diagnostic value, MRI costs patients some money and time. Also, we have reached the conclusion through an experiment with a group of patients in a certain hospital that the rest two methods is as efficient and useful as MRI in diagnosing ankle joint patients.

The purpose of this study was to introduce effects of Chukyu pharmacopuncture and Brainspotting on knee pain, headaches, and acute stress disorder of a patient with a traffic accident. We treated a patient with Chukyu pharmacopuncture and Brainspotting. Numerical rating scale (NRS), Range of Motion (ROM), Hyperextension Position (HEP), Effusion (Eff), Patella Compression Test (PCT), Frontal Flexion Position (FFP), McMurray (MCM), Lateral Joint Line Tenderness (LJLT), Medial Joint Line Tenderness (MJLT), Anterior Drawer Test (ADT), Lachman Test, Varus/Valgus stress, Beck Anxiety Inventory (BAI), Patient Health Questionnaire-9 (PHQ-9), Pittsburgh Sleep Quality Index (PSQI), Core Seven Emotions Inventory Short Form (CSEI-S), Subjective units of disturbance scale (SUDs), and Heart rate variability (HRV) were used to evaluate the patient. After the patient was treated by Chukyu pharmacopuncture and Brainspotting, the patient showed improvement in NRS, physical examination, and psychological symptom assessment. These results indicate that Chukyu pharmacopuncture and Brainspotting are effective on knee pain, headache, and acute stress disorder after a traffic accident.

Purpose: The aim of this study was to investigate the usefulness of mortise angle and fibular length measured in radiologic findings in predicting the ankle stability. Materials and Methods: One hundred cases fifty cases were randomly selected volunteers with normal ankle function and the other fifty cases were randomly selected patients whose ankle were treated in our hospital and who were followed for over 1 years with good results. A specific experimental fixture were made to get the even AP and lateral view and objective stress view. Results: The mortise angle and fibular length was not statistically significant to the degree of talar tilt angle under valgus or varus stress and that of displacement under anterior or posterior stress. Conclusion: The mortise angle and fibular length was not the objective predicting factors on the ankle stability. Maintenance of constrained talus in dynamic status is most important factors in determining the ankle stability.
