Purpose: We investigated the effect of isometric resistance exercise on the vastus medialis oblique muscle with inelastic tape and EMG biofeedback training applied to the patello-femoral joints of patients with patella malalignment. Methods: The 39 elderly subjects that had patella malalignment but no neuromuscular disorders were divided into a control group, taping group, and EMG biofeedback training group. Evaluations of function improvement performed before and after the treatment, as well as 4 weeks after treatment. Results: Change in pain in the knee joint were significantly different among groups (p<0.05). Maximum voluntary isometric contractility in the quadriceps muscle was significantly in the EMG biofeedback group (p<0.001). The WOMAC (Western Ontairo & McMaster Questionnaire) index showed a significant change (p<0.05) in pain, function, and total score. Taping and EMG biofeedback training showed a lasting effect until measurement 4 weeks after treatment. SF-36 (Medical outcome short form-36), which assesses the quality of life, did not significantly change. Conclusion: In osteoarthritis patients with a loss of patello-femoral joint function, isometric resistance exercise of the vastus medialis oblique muscle with taping seems effective.

Objective: The purpose of this study is to investigate the effect of treadmill gait training with patellar taping on gait abilities in chronic stroke patients. Design: Randomized controlled trial. Methods: Thirty chronic stroke patients who have been diagnosed at least six months or before were recruited in Gyeongin Rehabilitation Center Hospital, located in Incheon. Patients who were enrolled in this study were randomized to experimental group (n=15) or control group (n=15). Treadmill with patella taping training group patients were applied with patellar taping when they were being trained on a treadmill. Control group patients were being trained on a treadmill without any kind of taping. Gait parameters were measured with a GAITRite$^{(R)}$ system which evaluated gait performances. Gait trainings were done for 30 min/day, 5 days/week, for 4 weeks. Results: After treadmill training, treadmill with patella taping training group showed a significant improvement in gait abilities, including velocity, cadence, paretic and non-paretic step length, and double support period (p<0.05). However, in general treadmill group, there were no significant differences in gait parameters except velocity and cadence. There was a significant difference in gait performance in the experimental group compared with the control group, except for the gait symmetry ratio (p<0.05). Conclusions: According to this result of this study, it seems that application of patellar taping in treadmill gait training for chronic stroke patients significantly improved gait abilities of these patients. Also, we can conclude that patella taping is thought to be useful in real clinical settings where there are many chronic patients who are in need of improvement in their gait abilities.

PURPOSE: This study investigated the relationship among hip adduction angle, tibial rotation, and ITB length during an Ober test to determine the most appropriate position for performing the test. METHODS: The study included thirty-nine asymptomatic participants (23 males, 16 females). Their hip adduction angles were measured using the Ober test during three tibial rotation conditions (internal tibial rotation, external rotation, and neutral position). ITB length was calculated by measuring the position of the patella to lateral femoral condyle using ultrasonography (patella-condyle distance; PCD). RESULTS: The relationship among hip adduction angle, tibial rotation, and ITB length was analyzed under the three conditions using the Pearson correlation. The hip adduction angle of the internal tibial rotation, the external rotation, and the neutral position were significantly related to ITB length. Moreover, the hip adduction angle measured during the internal tibial rotation had the highest correlation with ITB length among the three conditions (r=.58, p<.001). CONCLUSION: Internal tibial rotation caused by the Ober test led to increased iliotibial band (ITB) tension and a decreased adduction angle. These findings support that tibial rotation influences the flexibility of ITB. Therefore, therapists should consider the position of the internal tibial rotation when taking measurements using an Ober test.

A 73-year-old man presented with a chief complaint of progressive left knee pain for two months. He had a history of total thyroidectomy and central lymph node dissection due to papillary thyroid carcinoma three months ago. MRI images revealed a solid mass in the left patella. A solid mass demonstrated low signal on T1 weighed image, and high signal on T2 weighed image. And whole body bone scan showed focal photon defect in same lesion of left patella. The histologic result of left knee lesion was adenocarcinoma, consistent with metastatic papillary thyroid carcinoma. Although patellar metastasis of papillary thyroid carcinoma is very rare, when knee pain and radiologic abnormality are noted, differential diagnosis of metastasis is necessary.

Chondroblastoma of the patella is a uncommon benign neoplasm in the middle aged person. Furthermore, a hemorrhagic cystic change associated with chondroblastoma is extremely rare. We experienced a case of chondroblastoma which underwent hemorrhgic cystic change. A fiftyyear-old female patient has suffered from right knee joint pain for 1 month before. Dominant gross feature was hemorrhagic cyst which was not involved into the joint space. Soft tissue was curetted and it was diagnosed to be chondroblastoma. The case was treated with curettage and bone graft.

This study was performed in 41 dogs with unilateral or bilateral medial patella luxation (MPL) and/or cranial cruciate ligament rupture (CCLR). These dogs were classified into 4 groups according to MPL grading system. Radiographic evaluation was performed for pelvis and stifle joint in the dogs. Norberg, inclination, quadriceps and femoral varus angle were measured and analyzed with MPL grading and the existence of cranial cruciate ligament rupture. The Norberg and inclination angle showed no differences between 4 grading groups and between CCLR and no CCLR groups. However, quadriceps and femoral varus angle were statistically different between grade 1, 2 and grade 3, 4 groups. They also have shown the statistical difference between CCLR and no CCLR group. Further studies for how these parameters affect the prognosis and the results of surgical treatment of MPL should be needed.

Purpose: To evaluate the results of percutaneous lateral release and arthroscopic medial plication for patients with recurrent patella dislocation. Materials and Methods: This study includes the thirty-one cases of patients who have had a surgical operation from March 2001 to March 2008. All the patients had recurrent patella dislocation after trauma history. The average age was 24.2 years old and the average follow up was 47.4 months (minimum 24 months). Results: The preoperative congruence angle, lateral patellofemoral angle, Lysholm score was $24.8^{\circ}$, $-6.2^{\circ}$, 75 points on average respectively. However, the postoperative congruence angle, lateral patellofemoral angle, Lysholm score was improved to normal range: $-2.8^{\circ}$, $10.2^{\circ}$, 95 points on average. Five cases showed the recurrent dislocation after operation. Among them, three cases showed femoral trochlear dysplasia. Conclusion: Percutaneous lateral release and arthroscopic medial plication showed satisfactory results for recurrent patella dislocation with low complication rate. However, in cases with femoral trochlear dysplasia, another surgical treatment may be considered.

To evaluate the effect of lead biomarkers including bone lead on neurobehavioral test in lead workers, 652 lead workers without any occupational exposure to organic solvent, mercury and arsenic were agreed to participate this study. For the control subjects 102 non-occupationally lead exposed blue collar workers in general manufacturing industries were also joined this study. All study subjects joined this study with written informed consent. The study variables of lead exposure were blood and patella lead. For the general characteristics of study subjects, standardized questionnaire regarding age, sex, past disease history, job duration, body mass index (BMI), drinking and smoking habit were provided. For the past history of neurotoxicity related diseases, all study subjects were interviewed by qualified occupational health physician. The results obtained were as follows: 1. Compared with controls without occupational lead exposure, lead exposed subjects had worse performance on all tests(p<0.05). 2. After adjustment for covariates (age, sex, job duration, education level, BMI, smoking and drinking status), the signs of the regression coefficients for blood lead were negative for 13 of the 14 tests. Blood lead was a significant predictor of poorer scores on 8 tests (simple reaction time(ms & root MSD), Trail-Making Test B, Digit Symbol Substitution, Purdue Pegboard assembly, Digit Span Test, Benton Visual Retention, and Purdue pegboard both hand). 3. After adjustment for covariates (age, sex, job duration, education level, BMI, smoking and drinking status), the signs of the regression coefficients for patella lead were negative for 12 of the 14 tests. Patella lead was a significant predictor of poorer scores on 8 tests (simple reaction time(ms). Purdue Pegboard assembly, Digit Span Test, Benton Visual Retention. Pursuit Aiming rest (no. of correct & no. of incorrect), Purdue pegboard non-dominant hand and both hand). With above results, blood lead and patella lead were associated with poorer performance of neurobehavioral tests. In addition, patella lead was confirmed to be better predictor of manual dexterity test in neurobehavioral test battery in lead workers
