Osteoarthritis is a common but often difficult problem to manage. Nonsurgical management, consisting of lifestyle modification, physical therapy and pharmacologic therapy (e.g., analgesics, anti-inflammatory medications), is often ineffective or leaves residual symptoms. Viscosupplementation is a newly available option for patients with symptomatic knee osteoarthritis that involves a series of intra-articular injections of hyaluronic acid. The exact mechanism of action is unclear, although increasing the viscoelasticity of the synovial fluid appears to play a role. The exact indications for viscosupplementation are still evolving, but it currently can be considered for use in patients who have significant residual symptoms despite traditional nonpharmacologic and pharmacologic treatments. In addition, patients who are intolerant of traditional treatments (e.g., gastrointestinal problems related to anti-inflammatory medications) can be considered for these injections.

PURPOSE: Controversies remain surrounding the choice of hyaluronic acid products and patient selection. A study was conducted to report the long-term survivorship of intra-articular injection effect of high molecular weight hyaluronic preparation hylan GF-20 (Synvisc-One) for patients with symptomatic knee osteoarthritis. MATERIALS AND METHODS: A retrospective observational analysis of a single therapeutic series was carried out. The analysis was conducted to determine therapeutic effect survivorship taking arthroplasty and any other surgical interventions as endpoint results. RESULTS: Seventy-seven consecutive patients (82 knees) were followed up for five years. At one-year follow-up, 71 knees (87%) responded to treatment and only 8 knees (10%) were offered arthroplasty due to persistence of symptoms. At five-year follow-up, 41 (50%) were still considered responders. During the study period, repeat injection was given in 9 knees (11%). Arthroplasty (either total or unicompartmental) was required in 26 (31%). Kaplan-Meier survivorship analysis of therapeutic effect demonstrated 67% survival at 5 years with arthroplasty as endpoint and 58% survival at 5 years with all secondary interventions as endpoint. CONCLUSIONS: This study demonstrates a significantly longer duration of clinical benefit of hylan GF-20 injection. Present results may suggest a notion of an ideal delay therapeutic strategy for patients not ready to receive an arthroplasty. Further studies will be required to help characterise these subsets of patients.

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.

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.
