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.

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.

Many authors have studies to relieve the pain after arthniscopic knee surgery. We undertook a randomized, double-blind trial to compare the efficacy of intraarticular morphme and bupivacaine between arthroscopic meniscus surgery group and cruciate ligament reconstruction group. As an results, intraarticular injection of morphine-bupivacaine combination is effective to control pain after minor athroscopic surgery such as menisectomy and meniscal repair ancf intraarticu]ar injection of mor- phine-bupivacaine combination is not effective to relieve pain after major arthroscopic surgery including cru- ciate ligament reconstruction. So, more potent analgesics should be adminishated.

OBJECTIVE: To compare to type and size of rotator cuff tear (RCT) in the transverse view before and after arthro-3D sonography. METHOD: Total 24 cases with rotator cuff tear were diagnosed according to ultrasonographic finding. All of patients were performed by a posterior-lateral approach for sono-guided intra-articular injection and underwent by both before and after arthro 3D sonogrpahy. We measured size (transverse, longitudinal, area) of RCT on the transverse scan in search of the largest lesion and the difference to type and size of RCT after arthrography. RESULTS: 3D ultrasonography detected full-thickness tear in 18 cases, partial-thickness tear in 6 cases before arthro-3D sonograhy. Change in the diagnosis of rotator cuff tear after arthro-3D sonogrphy; 3 partial-thickness tear were diagnosed as full-thickness tear. The size (transverse, longitudinal, area) of RCT was increased significantly after arthro-3D sonography compared with that before arthro 3D sonography. CONCLUSION: Arthro-3D sonography is useful for evaluation the configuration of RCT. Using this method, we can provide the objective and steric image of RCT.

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.
