The purpose of this study was to investigate the arthro-sonographic appearance of the chronic anterior talofibular ligament (ATFL) injury. Twenty-nine patient, who were identified to have partial or complete ATFL tears by conventional ultrasonography were included. Intraarticular injection of 5 mL of fluid (2.5 cc lidocaine+2.5 saline) was performed under ultrasound-guidance, which was followed by arthrosonography. Among 23 patients with partial tear which was detected by the conventional ultrasonography, 11 patients were identified to have complete tear by the arthrosonography. Among 6 patients with complete tear was detected by conventional ultrasonography, all of them identified to have complete tear by the arthrosonography. Arthrosonography is helpful in evaluation the configuration of ATFL complete tear and detecting complete tear by making them appear larger and apparent after instillation of fluid.

PURPOSE: To assess the feasibility of ultrasound-guided shoulder joint injections by the anterior and posterior approaches for performing a MR arthrography. MATERIALS AND METHODS: Between April 2007 and June 2008, 28 patients underwent ultrasound-guided intra-articular contrast injections for a MR arthrography. This study was approached using the antegrade method. As well, all injections were performed by one radiologist. The patient selection criteria for the anterior and posterior approaches were randomly for the anterior approach and alternatively for the posterior approach. Each approach included 13 cases and each were injected by the anterior or posterior approaches exclusively . The patients were classified into three groups as follows: 1) the successful intra-articular injection group, 2) the small leakage group, and 3) the injection failure group. RESULTS: Of the 15 patients that underwent the anterior approach, two were unsuccessful for the MR arthrography. Whereas, two other cases experienced small leakage. The two failed MR arthography cases using the anterior approach were later injected using the posterior approach. The 15 patients subjected to the posterior approach to perform a MR arthrogram were successful in all cases, without any leakage. CONCLUSION: The ultrasound-guided intra-articular injections were feasible with a high success rate by both the anterior and posterior approaches. However, better results were achieved from the posterior approach than the anterior approach in this study.

OBJECTIVE: To investigate the usefulness and indications of arthrosonography by testing if the new technique could provide additional information on the degrees of rotator cuff tears when compaired to the findings of conventional ultrasonographic examinations. METHOD: Thirty six patients, who were identified to have partial or full-thickness rotator cuff tears by conventional ultrasonography, were included. Intraarticular injection of 15 ml of fluid was performed via posterior approach under ultrasound-guidance, which was followed by arthrosonography. RESULTS: Among 26 patients with partial-thickness tear which was detected by the conventional ultrasonography, eight were identified to have full-thickness tears by the arthrosonography. Although the difference was not significant, the grade 3 partial-thickness tear in the conventional sonography had a higher rate of being identified as full- thickness tear in the arthrosonography than the grade 2 partial-thickness tears. The size of partial-thickness tear was increased after instillation of fluid in the arthrosonography. CONCLUSION: Arthrosonography would be useful in differentiating partial- and full-thickness tears. When a tear of the rotator cuff tendon, especially a grade 3 partial-thickness tear, is detected in the conventional sonographic examination, an obscured full-thickness tear should be suspected and subsequent arthrosonographic procedure could be administered to clarify the extent of the lesion. Moreover, arthrosonography might be helpful in detecting partial-thickness tears by making them appear larger after instillation of fluid.

OBJECTIVE: To evaluate the efficacy of intra-articular hyaluronic acid and steroid injection in osteoarthritis of the knee. METHOD: Among 653 patients with osteoarthritis, 531 patients were participated in this study. They were divided to three groups; A, treated with hyaluronic acid 2.5 ml intra-articular injection once a week for 5 times; B, hyaluronic acid 2.5 ml once a week for 5 times with triamcinolone 20 mg once at the first time; C, only triamcinolone 20 mg at the first time. Before injection, X-ray with standing view were checked and divided according to Kellgren's grade of osteoarthritis. The amount of pain relief was assessed by pain rating score (PRS) and visual analogue scale (VAS) 1 week before and 1 month after the treatment. RESULTS: The degree of pain relief by PRS and VAS were all improved at 1 month after injection compared with pre-injection status (p<0.001). Intra-articular hyaluronic acid injection was more effective in Kellgren's grade I, II than in III, IV in pain relief and hyaluronic acid with steroid injection was more effective in III, IV. CONCLUSION: The results suggest that intra-articular hyaluronic acid injection would be effective for the treatment of patients with osteoarthritis.

OBJECTIVE: To evaluate the effect of tear after passive ROM exercise during distension arthrography in patients with frozen shoulder. METHOD: Fifteen patients (male: 7, female: 8, mean 57.5 years old) who had complained of shoulder pain with decreased ROM at least 3 months prior were enrolled. Distension arthrogrphy of 35 ml of fluid which contained 10 ml of 1% lidocaine, 1 ml of depomedrol (40 mg), 19 ml of normal saline, and 5 ml of radiocontrast material was injected by a single physician. Then if there was no capsular tear, passive ROM exercise was performed for two minutes. RESULTS: In seven of the thirteen patients, the occurrence of capsular tear was observed after only distension arthrography. In five of the six patients without capsular rupture, the occurrence of capsular tear was observed by passive ROM exercise after distension arthrography. Two patients were interrupted because of severe pain. Clinical outcomes of occurrence of capsular tear by conventional distension arthrography and by passive ROM exercise after distension arthrography were similar. CONCLUSION: Passive ROM exercise after distension arthrography could serve as an effective method of capsular tear in patients with frozen shoulder.

PURPOSE: To evaluate the treatment results of intraarticular injection according to the frequency of hyaluronic acid with mesenchymal stem cells on the osteochondral defect of rabbits' medial femoral condyles. MATERIALS AND METHODS: A 5 mm diameter and 4 mm depth osteochondral defect was made on the medial femoral condyles of 18 rabbits, divided into six groups. One week after osteochondral defect, group B was injected intraarticularly with hyaluronic acid (HA), group C with mesenchymal stem cells (MSCs), and group D, E and F with both HA and MSCs. Group E and F received second HA injection a week after. Further, group F received third HA injection in the third week. RESULTS: In a macroscopic evaluation, groups B (6; range, 5-8), C (6; range, 6-7), D (7; range, 6-7), E (6.5; range, 6-8) and F (7.5; range, 6-8) showed statistically significant improvements in osteochondral defect healing, compared with that of group A (4; range, 3-5) (p=0.002). In histological evaluation, groups B (11.5; range, 11-13), C (13; range, 12-18), D (16; range, 13-18), E (17.5; range, 13-20), and F (19.5; range, 12-22) showed statistically significant differences in osteochondral defect healing, compared with group A (8; range, 6-9) (p=0.006). CONCLUSIONS: The intraarticular injections of MSCs or HA can play an effective role during the healing osteochondral defects in rabbits.
