Comparison of the Clinical Results of HILT Versus ESWT in the Lateral Epicondylitis

PURPOSE: To compare the clinical results of High intensity laser therapy (HILT) versus Extracorporeal shock wave therapy (ESWT) in the lateral epicondylitis. MATERIALS AND METHODS: Fifty patients who suffer from lateral epicondylitis for more than six month duration were randomly assigned two treatment groups. Group 1 (n=25) was treated with HILT using a HIRO 3.0 laser(ASA srl, Arcugnano, Italy) and total energy was administered approximately 1200J following a standard protocol for each session; Group 2 (n=25) recieved with ESWT treatment using an EvoTron(Switech Medical AG, Kreuzlingen, Switzerland) for a total of 1000 shocks for each session. The patients were evaluated by assessment of pain using visual analog scale (VAS) and simple elbow test (SET). Comparision of overall clinical outcomes were evaluated by Roles and Maudsley score at 9 months. RESULTS: Average VAS and SET scores were significantly improved in two groups, also achieved significant improvement of symptoms at 9 months follow up according to Roles and Maudesley scores(P<0.05). The success rate in the HILT group was 76 % and in the ESWT group was 72 %. CONCLUSIONS: This study suggests that HILT could be considered as effective and noninvasive treatment modality for lateral epicondylitis.

Total Hip Arthroplasty with F2L Multineck Cementless Femoral Stem

PURPOSE: To analyze the results of cementless total hip arthroplasty with a F2L Multineck femoral stem. MATERIALS AND METHODS: A total of 64 patients (73 hips), who underwent cementless total hip arthroplasty with a F2L Multineck femoral stem, SPH acetabular cup and a ceramic liner from December of 1998 to October of 2001 were followed up for at least 4 years, were selected for the clinical and radiological evaluations. RESULTS: At the final evaluation, 63 patients had an improved average Harris hip score ranging from 51.4 preoperatively to 95.1. None of the patients had any significant leg length inequality. Thigh or inguinal pain was observed in 3 hips (1 hip of femoral stem subsidence and 2 hips of damaged ceramic parts), for which revision total hip arthroplasty was performed. Hip dislocation occurred in 2 hips within 2 weeks after surgery and conservative management was performed after a closed reduction. CONCLUSION: Total hip arthroplasty with a F2L Multineck femoral stem produced satisfactory results. Postoperative complications such as hip dislocation and leg length inequality could be minimized by modulating the anteversion angle, femoral offset and leg length with multineck femoral stem.

Comminuted Intercondylar Fracture of the Distal Humerus in Adults

PURPOSE: To evaluate the therapeutic results of communited intercondylar fractures of the distal humerus that were treated by surgical treatment. MATERIALS AND METHODS: From January, 1998 to December, 2004, we reviewed fifteen cases of intercondylar fracture of the distal humerus, which were treated by surgical treatment. The follow up period ranged from six month to 5 years. The functional results were evaluated using Broberg and Morrey's functional scale according to surgical approach, type of plate and location of plating. RESULTS: The functional results were as follows; seven excellent, six good, one fair and one poor. The mean range of motion in elbow joint was 7~106 degrees. The mean functional score was 86.6 points through olecranon osteotomy, 90.5 points through Campbell's posterior approach. The mean functional score was 91.6 points in cases using 2 reconstruction plate, 78 points in cases using 1 reconstruction plate and 1/3 semitubular plate, and 86 points in case using 1 reconstruction plate and lag screws. The mean functional score was 88.9 points in cases by posterior and lateral fixation, 86 points in cases by both posterior fixation and 97 points in case by both lateral fixation. CONCLUSION: There are no significant differences in treatment outcome according to surgical approach, different plate and location of plating.

Comparative Analysis between Patellar Resurfacing and Retention in Total Knee Arthroplasty: 5-year Follow-up Result / 대한정형외과학회잡지

PURPOSE: To compare the clinical and radiological results between patellar resurfacing, group and patellar retention group in total knee arthroplasty. MATERIALS AND METHODS: Of the 74 patients who underwent total knee arthroplasty on due to knee osteoarthritis since March 1996, and followed-up for at least for 5 years, there were 42 and 32 cases in the patellar retention and patellar resurfacing groups respectively. These subjects were evaluated preoperatively and at 1 and 5 years postoperatively using the pain score, Hospital for Special Surgery (HSS) knee score, walking and stair-climbing in knee function score and radiological analysis. The radiological evaluation was achieved by measuring the patellar tilt angle and displacement with a 45degreesmerchant view. The results were analyzed using the student's t-test. RESULTS: There were no significantly differences between the patellar resurfacing and patellar retention groups in the pain score, HSS knee score, walking in knee function score and radiological analysis (p>0.05), but the patellar retention group achieved superior results in stair-climbing (p<0.05). CONCLUSION: The clinical and radiological results were similar in the patellar retention and patellar resurfacing groups. The use of selective indications of patellar resurfacing is required in order to achieve better results for total knee arthroplasty.
