Effects of Sodium Hyaluronate in the Treatment of Rotator Cuff Lesions: A Systematic Review and Meta-analysis. Orthop J Sports Med 2022; 10:23259671221115743. [PMID: 36051971 PMCID: PMC9425898 DOI: 10.1177/23259671221115743] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/22/2022] [Accepted: 05/17/2022] [Indexed: 12/05/2022] Open
Abstract
Background: Rotator cuff pathology is a common cause of pain and shoulder dysfunction. Several nonoperative treatment modalities have been developed for rotator cuff lesions, but their relative efficacy is not well-established. Purpose/Hypothesis: The purpose of this systematic review and meta-analysis was to evaluate the efficacy and safety of sodium hyaluronate (SH) in the treatment of patients with rotator cuff lesions. It was hypothesized that SH would be found to be more effective than other nonoperative regimens. Study Design: Systematic review; Level of evidence, 3. Methods: We searched various databases to identify eligible studies that evaluated the effects of SH on the pain and shoulder dysfunction attributed to rotator cuff lesions. Outcome measures were pain visual analog scale (VAS) score; Constant score; University of California, Los Angeles (UCLA) score; satisfaction rate; complications; and factors affecting the pain VAS score. Outcomes were reported as weighted mean difference (WMD) or risk ratio. Results: A total of 9 studies were identified for data analysis. Compared with patients treated with other nonoperative treatments (controls), those treated with SH had significantly improved pain VAS scores at 1 week (WMD = −0.95; 95% CI, −1.75 to −0.16; P = .019), 2 weeks (WMD = −1.05; 95% CI, −2.07 to −0.03; P = .044), 3 weeks (WMD = −1.49; 95% CI, −2.88 to −0.11; P = .035), and 4 weeks (WMD = −2.12; 95% CI, −4.05 to −0.19; P = .031). The Constant score was significantly improved in the SH group versus controls at 2 weeks (WMD = 3.25; 95% CI, 2.36 to 4.13; P < .001), 3 months (WMD = 20.28; 95% CI, 0.54 to 40.03; P = .044), and 6 months (WMD = 5.58; 95% CI, 0.94 to 10.21; P = .018). The UCLA score and satisfaction rate did not differ significantly between the 2 groups. No complications associated with SH were reported in the included studies. Metaregression analysis showed that, except for study design (coefficient = −1.64; 95% CI, −2.64 to −0.63; P = .002), none of the variables (sample size, tear type, control treatments) significantly predicted the difference in VAS pain score between SH and other treatments. Conclusion: The present meta-analysis demonstrated that SH was effective in treating patients with rotator cuff lesions.

The Effect of Intra-articular Injection of Hyaluronic Acid in Frozen Shoulder: a Systematic Review and Meta-analysis of Randomized Controlled Trials. J Orthop Surg Res 2022; 17:128. [PMID: 35241100 PMCID: PMC8896272 DOI: 10.1186/s13018-022-03017-4] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/16/2022] [Accepted: 02/16/2022] [Indexed: 02/08/2023] Open
Abstract
Background Frozen shoulder (FS) is a common progressive disorder that causes restricted motion and refractory pain undermining quality of life. Intra-articular hyaluronic acid (HA) injection is a widely adopted conservative therapy relieving symptomatic FS, whereas the effect of which were contradictory and unclear in current literatures. The aim of the present study is to investigate whether intra-articular HA administration facilitates symptomatic pain relief and functional improvements in patients diagnosed with shoulder FS. Methods The PubMed, Embase, Cochrane Library electronic databases and Google scholar were searched, from inception to 15th Jan 2022. Randomized controlled trials (RCTs) comparing intra-articular HA administration with any other non-surgical treatment in patients with FS were included. Risk of bias was evaluated using the Cochrane risk-of-bias tool and meta-analyses were undertaken to pool the data of visual analog scale for pain, range of motion (ROM) in external rotation, abduction, and flexion, as well as Shoulder Pain and Disability Index (SPADI), Constant score and American Shoulder and Elbow Surgeons (ASES). Results The present study included 7 RCTs involving 504 patients. The results provided no support for superior pain control in patients undergoing HA injection compared with any other treatment (p = 0.75). Furthermore, HA group failed to exert superior improvements to other treatments in ROM concerning abduction (p = 0.69) and flexion (p = 0.33). However, HA injection was observed to facilitate functional recovery in external rotation (p = 0.003). In addition, the pooled data showed a significant higher SPADI score in control group than in HA group (p = 0.01), while no statistical significance between two groups was observed in Constant score (p = 0.36) and ASES (p = 0.76). Conclusions The current meta-analysis suggested that HA is a beneficial treatment procedure in improving the ROM of the shoulder for patients with FS, whereas the effect in relieving pain may be equal to the existing therapy. In conclusion, Intra-articular HA injection is recommended for FS patients.

Abstract
Background Few studies have reported the effects of simultaneous injections of corticosteroid (CS) and hyaluronic acid (HA) on adhesive capsulitis (AC) of the shoulder. This study investigated the synergistic effects of simultaneous intra-articular injections of CS and compared them to those of CS or HA alone. Method Sixty patients with AC were enrolled in this randomized, placebo-controlled trial. The participants were divided into 4 groups: saline, CS, HA, and CS with HA groups. The primary outcome measure was changes in the Shoulder Pain and Disability Index (SPADI) scores at one month. The secondary outcome measures included changes in pain, range of motion, muscle strength, and additional shoulder functional scores at 1 day, 1 week, and 1, 3, and 6 months after injection. Results After 1 month, changes of the SPADI scores were significantly higher in the CS with HA group (−58.4%) than those in the saline (−7.7%) and HA (−14.4%) groups. The score changed more in the CS with HA group than that in the CS group (−43.7%), but there was no significant difference. In the changes in pain, the CS with HA group showed significantly better and faster effects than the saline and HA groups. In the changes of range of motion, functional scores, the CS with HA group showed better results than the saline and HA groups. Conclusion In the treatment of AC, the simultaneous injection of CS and HA was more effective in improving SPADI scores at one month after injection than a single injection of CS or HA.

What is the Evidence of Hyaluronic Acid and Polyacrylamide Hydrogel in Intra-articular Therapy in Equines? Systematic Literature Review. J Equine Vet Sci 2020; 86:102909. [PMID: 32067659 DOI: 10.1016/j.jevs.2019.102909] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2019] [Revised: 12/27/2019] [Accepted: 12/29/2019] [Indexed: 10/25/2022]
Abstract
A systematic review was conducted to investigate evidence to support or refute the use of hyaluronic acid and polyacrylamide hydrogel as intra-articular therapy in equines, which are frequent treatment options in the routine of veterinarians of equines in cases of osteoarthritis. In total, 19 studies were included, among clinical and in vitro studies, as well as a retrospective series of cases. The outcomes of the included studies provided fragile evidence supporting the recommendation for intra-articular use of hyaluronic acid. No study was included showing any clinical outcome in diseased synovial tissues of the polyacrylamide hydrogel. There is no concrete evidence of benefits, treatment protocols, and mechanisms of action of hyaluronic acid in the joint therapy in equines.

Adhesive capsulitis: review of imaging findings, pathophysiology, clinical presentation, and treatment options. Skeletal Radiol 2019; 48:1171-1184. [PMID: 30607455 DOI: 10.1007/s00256-018-3139-6] [Citation(s) in RCA: 42] [Impact Index Per Article: 8.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/25/2018] [Revised: 12/11/2018] [Accepted: 12/17/2018] [Indexed: 02/02/2023]
Abstract
Adhesive capsulitis, commonly referred to as "frozen shoulder," is a debilitating condition characterized by progressive pain and limited range of motion about the glenohumeral joint. It is a condition that typically affects middle-aged women, with some evidence for an association with endocrinological, rheumatological, and autoimmune disease states. Management tends to be conservative, as most cases resolve spontaneously, although a subset of patients progress to permanent disability. Conventional arthrographic findings include decreased capsular distension and volume of the axillary recess when compared with the normal glenohumeral joint, in spite of the fact that fluoroscopic visualization alone is rarely carried out today in favor of magnetic resonance imaging (MRI). MRI and MR arthrography (MRA) have, in recent years, allowed for the visualization of several characteristic signs seen with this condition, including thickening of the coracohumeral ligament, axillary pouch and rotator interval joint capsule, in addition to the obliteration of the subcoracoid fat triangle. Additional findings include T2 signal hyperintensity and post-contrast enhancement of the joint capsule. Similar changes are observable on ultrasound. However, the use of ultrasound is most clearly established for image-guided injection therapy. More aggressive therapies, including arthroscopic release and open capsulotomy, may be indicated for refractory disease, with arthroscopic procedures favored because of their less invasive nature and relatively high success rate.

Abstract
Purpose
The aim of this study was to evaluate the efficacy and safety of intra-articular injection treatment with high molecular weight HA (Hyalubrix, 30 mg/2 mL, molecular weight > 1,500 kDa) in patients affected by moderate to severe glenohumeral osteoarthritis (OA).
Methods
Seventy-eight patients, affected by shoulder OA grade II–IV were randomized in two groups. Patients included in case group were treated with three intra-articular injections of HA and a specific physiotherapy program, whereas patients included in the control group received the only physical therapy. The follow-up examination was 6 months for both groups. The evaluation of functional status of treated shoulder, range of motion, and pain was performed before treatment and at the final follow-up examination by means of the Constant score. The safety evaluation of the treatment was also performed recording any adverse events.
Results
Statistical analysis revealed a significant difference (
p
< 0.05) between the two groups in terms of pain reduction and improvement in the activities of daily living. In particular, case group subjects affected by grade III and IV OA had a significant improvement in the Constant score (18.2 ± 5.4 and 19.2 ± 5.9, respectively).
Conclusion
This study showed that the combination of intra-articular injection of hyaluronic acid (Hyalubrix, 30 mg/2 mL) with physical therapy program was more effective in comparison with the only physical therapy in reducing pain in patients affected by glenohumeral OA.
Level of Evidence

Abstract
PURPOSE numerous experimental and clinical studies in osteoarthritis (OA) have demonstrated that intra-articular (IA) administration of hyaluronic acid can improve the altered rheological properties of the synovial fluid and exert protective and reparative effects on the joint structure. The objective of this study was to evaluate the safety and performance of HYADD®4-G (Hymovis®) in patients with glenohumeral joint OA. METHODS forty-one patients with shoulder pain and limited shoulder function resulting from concentric glenohumeral joint OA were enrolled in a multicenter clinical trial. Patients received two HYADD®4-G injections administered one week apart. The main outcome measure was improvement in shoulder pain on movement at six months as assessed through a 100-mm visual analog scale (VAS), range of motion (ROM) values, and Constant-Murley Shoulder Outcome Score (CS). RESULTS two IA injections of HYADD®4-G (Hymovis®) significantly decreased pain and improved shoulder function for up to six months from the first injection. The VAS score decreased (from 66.1 mm to 37.7 mm at six months) and improvements were recorded in the total CS and in the ROM values ( rotation decreased from a mean value of 54.2° at baseline to 63.2° at six months and internal rotation from a mean value of 44.0° at baseline to 45.7° at 26 weeks). No serious adverse events occurred. CONCLUSIONS the study results demonstrated that two IA injections of HYADD®4-G (Hymovis®) may be a safe and effective treatment option for shoulder pain associated with glenohumeral OA and that the effects of the injections are still present for up to six months after the treatment. LEVEL OF EVIDENCE Level IV, therapeutic case series.

Abstract
With the aging of the world's population, the prevalence of age-related diseases is continually increasing, especially osteoarthritis, the most common form of joint disease. In addition to its high prevalence, osteoarthritis has been correlated with high medical and social costs. Among the treatment methods, viscosupplementation (intra-articular injection of hyaluronic acid derivatives) has been gaining more prominence. The substances used are high molecular weight polysaccharides that, in addition to mechanical functions of weight distribution and joint lubrication, have anti-inflammatory properties and physical-chemical action on a variety of joint characteristics. These effects are directly proportional to the molecular weight and concentration of the drug used and any cross-links that may be present in the drug. Viscosupplementation is a simple procedure and can be performed in outpatient clinics. It provides benefits regarding pain and function, and also favorably alters the course of the disease, through quantitatively and qualitatively improving the joint cartilage. It has a good safety profile and favorable cost-effectiveness relationship, and is indicated both for osteoarthritis cases and after an arthroscopic procedure.

Effectiveness of hyaluronic acid administration in treating adhesive capsulitis of the shoulder: a systematic review of randomized controlled trials. BIOMED RESEARCH INTERNATIONAL 2015; 2015:314120. [PMID: 25802845 PMCID: PMC4329841 DOI: 10.1155/2015/314120] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/11/2014] [Accepted: 01/18/2015] [Indexed: 11/24/2022]
Abstract
Introduction. Adhesive capsulitis (AC) of the shoulder presents with an insidious onset of pain and progressive limitation of shoulder movement. Objectives. To investigate whether intra-articular hyaluronic acid (HA) administration alone is superior to conventional therapies and whether the addition of intra-articular HA administration to conventional therapies improves clinical outcomes in patients with AC. Methods. The PubMed, EMBASE, CINAHL, and Cochrane Library electronic databases were searched without language restrictions in July 2014 with a priori defined inclusion and exclusion criteria. Results. Four randomized controlled trials (273 participants, 278 shoulders) were included in this review. Two trials compared intra-articular HA administration with conventional therapies and 2 trials evaluated intra-articular HA administration as an addition to conventional therapies. Pain and shoulder function/disability outcomes in the HA injection group were not superior to those achieved in the conventional therapy groups. No significant differences in pain or shoulder function/disability outcomes were noted between the groups with and without adjunctive HA administration. Conclusions. Intra-articular HA administration alone is not superior to conventional AC treatments, and the addition of intra-articular HA administration to conventional therapies does not provide significant added benefits. HA administration in AC patients who are receiving conventional therapies should be evaluated to avoid unnecessary medical expenditure.

Abstract
Background: Conservative treatments are especially in patients with glenohumeral osteoarthritis (GH-OA) important, since shoulder arthroplasty has its limitations. In this systematic review, we will evaluate the current evidence regarding the efficacy of intra-articular (IA) infiltration treatment options in patients with GH-OA. Materials and Methods: The following databases are searched: Pubmed/Medline, Cochrane Clinical Trial Register, Embase and the WHO clinical trial register. All IA injection products used for the treatment of shoulder OA in humans are included. Results: A total of 8 studies could be included in this review. Hyaluronic acid (HA) showed effect sizes of 2.07, 2.02 and 2.11 at 6, 12 and 26 weeks follow-up, respectively. Placebo (1.60, 1.82 and 1.68) also showed stable effect sizes at the same time points. The efficacy of corticosteroids (CS) decreased rapidly at follow-up (1.08, 0.43 and 0.19). Although statistical significant, the maximum difference in effect sizes between HA and placebo was only 0.43 with absolute values between 2.0 and 6.4 on a 100-point visual analogue score for pain. Conclusion: IA treatment with HA has a good efficacy at follow-up compared to baseline. However, the difference in efficacy between HA and placebo never reaches the minimal clinically important difference at any of the follow-up points. We are not able to give clear recommendations for the use of IA CS injections in patients with GH-OA. In future research, we recommend focusing on sufficiently powered randomized trials to compare the efficacies of HA, CS, placebo and other IA treatment options in patients with GH-OA.

Abstract
Background Subacromial impingement is a common cause of shoulder complaints in general practice. When the initial treatment with acetaminophen and low dose Non Steroidal Anti Inflammatory Drugs fails, triamcinolone acetonide injections are commonly used. Triamcinolone acetonide injections are effective at four to six weeks. Little is known about the pain relief effect of triamcinolone acetonide injections in the first days after injection and the effect of repeated injection. In this study we investigate the effect of triamcinolone acetonide injections compared to hyaluronic acid and NaCl injections using a pain diary. Methods 159 Patients recruited for an RCT comparing the effect of subacromial injections of triamcinolone acetonide, hyaluronic acid and sodium chloride (NaCl) were used in this study. They were blinded for their treatment and could receive up to three injections. Primary outcome consisted of the patient perceived pain on a VAS score recorded on a daily basis during 21 days following injection. Secondary outcome consisted of the amount of taken escape medication following injection and adverse effects. Results All patients received the first injection. 150 patients also received the second and third injections. 97% Of the paper and pencil pain diaries were returned for data analysis. The triamcinolone acetonide group showed the largest decrease in pain on the VAS scores after injection compared to the hyaluronic acid and NaCl group in the first week after injection. The reduction in pain was best achieved after the first injection, the second triamcinolone acetonide injection showed a further reduction in pain. The third triamcinolone acetonide injection only showed a slight improvement in pain reduction. Conclusions In this study we could show a booster effect in pain reduction after repeated triamcinolone acetonide injection. The triamcinolone acetonide group showed a faster reduction in pain after injection compared to the hyaluronic acid and NaCl group. The effect was best seen after the first and second triamcinolone acetonide injection, it is therefore questionable whether it is necessary to repeat triamcinolone acetonide injections more than two times.

Abstract
The goal of this study was to prospectively compare the early clinical results of intra-articular injection of hyaluronate or corticosteroid in patients with idiopathic adhesive capsulitis. The authors' hypothesis was that there would be no difference between groups. Sixty-eight patients with idiopathic adhesive capsulitis were equally randomized to receive either corticosteroid or hyaluronate injection. All patients underwent standard physical examination and magnetic resonance imaging. Intra-articular injection was performed through an anterior approach by the same orthopedic surgeon without image guidance. Patients were followed up 2 and 12 weeks after completion of the injection. The primary outcome was the Constant score at week 12. Secondary outcomes included the visual analog scale (VAS) pain score, the American Shoulder and Elbow Surgeons (ASES) score, and range of motion at each time point. No significant differences were noted in preoperative demographic features or baseline shoulder function between groups. After treatment, no significant differences were noted in early clinical outcomes (at weeks 2 and 12) with VAS, ASES, and Constant scores between groups (all P>.05). Evaluation of range of motion showed no difference in forward elevation or external rotation at each time point. Internal rotation was significantly lower at week 2 in the hyaluronate group compared with the corticosteroid group (P=.015). Internal rotation improved at week 12, with no significant difference between groups. Patients treated with intra-articular injection of hyaluronate and corticosteroid for idiopathic adhesive capsulitis showed significant improvement in early clinical scores and range of motion without significant differences between groups.

Abstract
Context: Intra-articular injections into the glenohumeral joint are commonly performed by musculoskeletal providers, including orthopaedic surgeons, family medicine physicians, rheumatologists, and physician assistants. Despite their frequent use, there is little guidance for injectable treatments to the glenohumeral joint for conditions such as osteoarthritis, adhesive capsulitis, and rheumatoid arthritis. Evidence Acquisition: We performed a comprehensive review of the available literature on glenohumeral injections to help clarify the current evidence-based practice and identify deficits in our understanding. We searched MEDLINE (1948 to December 2011 [week 1]) and EMBASE (1980 to 2011 [week 49]) using various permutations of intra-articular injections AND (corticosteroid OR hyaluronic acid) and (adhesive capsulitis OR arthritis). Results: We identified 1 and 7 studies that investigated intra-articular corticosteroid injections for the treatment of osteoarthritis and adhesive capsulitis, respectively. Two and 3 studies investigated the use of hyaluronic acid in osteoarthritis and adhesive capsulitis, respectively. One study compared corticosteroids and hyaluronic acid injections in the treatment of osteoarthritis, and another discussed adhesive capsulitis. Conclusion: Based on existing studies and their level of evidence, there is only expert opinion to guide corticosteroid injection for osteoarthritis as well as hyaluronic acid injection for osteoarthritis and adhesive capsulitis.

Abstract
Background: Rotator cuff disease is a common cause of shoulder pain. There are studies about the effectiveness of sodium hyaluronate injection on shoulder and knee pain, but few studies demonstrating the efficacy of sodium hyaluronate ultrasonography guided injection for rotator cuff disease. This study evaluates effectiveness of ultrasonography guided subacromial sodium hyaluronate injection in patients with impingment syndrome without rotator cuff complete tear. Materials and Methods: This prospective, double-blind, placebo controlled clinical trial study was performed among 40 patients with subacromial impingement syndrome without complete tear of rotator cuff. Patients randomly injected ultrasonography guided in 2 groups: Case group by 20 mg of sodium hyaluronate (Fermathron™) and control group by 0.9% normal saline. Both groups received 3 weekly injections. The pain score (100 mm visual analogue score [VAS]) was evaluated before first injection and one week after each injection. The constant score was evaluated before first and 12 week after last injection. Data was analyzed statistically by Independent t-test. Results: In both groups mean VAS has decreased, but more significantly in case group (P < 0.001). Mean constant score was significantly higher in case group 12 weeks after last injection (P < 0.001). The constant score improved 12 weeks after the last injection in both groups with a significantly better result in case group (P < 0.001). Conclusion: Subacromial injections of sodium hyaluronate are effective in treating rotator cuff disease without complete tears.

Abstract
Rotator cuff lesions are quite common and in some cases Hyaluronic Acid (HA) can play a role in pain relief and in restoring functions. The aim of the study was to point out the correct indications for HA injection therapy through a prospective study: firstly defining the safety and efficacy of HA in the different grades of cuff tears, then evaluating the maintenance at 90 days, as secondary endpoint. A prospective, open-label uncontrolled study was developed. One hundred patients diagnosed with different rotator cuff lesions were divided into 4 grade-related groups based on a modified Neer's classification. A cycle of 3 US-guided injections of medium-low weight HA was performed through the anterolateral way, one every two weeks. Follow-up was at 0, 15, 30, 45 and 90 days. VAS, Oxford-Shoulder-Score (OSS) and Constant-Murley were used for evaluations. In grade I and II, at day 45, a significant reduction of VAS and increase of Constant-Murley and OSS resulted. In grade IV VAS slowly decreased in the first 45 days, while OSS and Constant did not improve significantly. In grade III patients had no benefit from a clinical and subjective point of view. At ninety days the beneficial effect was still maintained in grades I, II and IV. Overall, the treatment showed a high tolerability profile. In conclusion, patients affected by bursitis or partial cuff tears benefit from HA, while in cuff arthropathy HA might only delay surgery or represent a palliative. In complete tears HA was not effective in pain relief or functional recovery.

Abstract
BACKGROUND Rotator cuff (RC) tendinopathy is a common cause of pain and shoulder dysfunction. The literature evidence suggests that a combination of overuse and extrinsic compression may induce chronic RC tendinopathy. Aim of the current study was to compare the results of subacromial sodium hyaluronate injections with rehabilitation therapy. MATERIALS AND METHODS We enrolled 48 patients (M/F: 26/22; mean age: 50 years; shoulder right/left: 29/19) with persistent shoulder pain for at least 4 months. Exclusion criteria were as follows: RC tear, calcifying tendinitis, glenohumeral instability, osteoarthritis, rheumatic diseases, physical therapy and/or injection in the previous 4 months, shoulder surgery, anesthetic nerve block, trauma, and severe medical diseases. The included subjects received either two ultrasound-guided subacromial hyaluronic acid (HA) injections (25 patients, HA group) at baseline and 14 days, or underwent rehabilitation therapy (23 patients, Physio group) including active shoulder mobilization, soft tissue stretching and humeral head positioner and propeller muscles strengthening for 30 days (3 sessions every week). Clinical assessment of shoulder function was performed with visual analog scale score for pain (0-100), Oxford Shoulder Score (OSS), and Constant-Murley Score (CS). Overall, patients were examined at baseline, week 2, week 4, week 12, and week 24. Statistical significance was set at 5 % (p < 0.05). RESULTS Reduction in overall pain in the HA group was statistically significant at week 2 (p < 0.05) week 4 (p < 0.05), week 12 comparing to baseline. Similarly, pain subscores (at night and with activity) were significantly lower at week 2 (p < 0.05), week 4 (p < 0.05), and week 12 (p < 0.05), respectively. In the Physio group, pain decreased significantly at week 2 (p < 0.05) but not maintained at week 4 (p > 0.05), week 12 (p > 0.05), and week 24 (p > 0.05). CS and OSS in the HA group increased significantly at week 2 (p < 0.05), week 4 (p < 0.05), and week 12 (p < 0.05). A non-statistically significant increase in clinical scores was found at week 24 (p > 0.05). A significant improvement of CS and OSS we found in the Physio group at week 2 (p < 0.05), but not at weeks 4, 12, and 24 (p > 0.05). CONCLUSIONS Subacromial HA injections could be an effective and safe alternative treatment for patients suffering from RC tendinopathy. We believe that the results of this study are encouraging but not lasting and we might suppose that a series of three to four subacromial sodium hyaluronate injections could provide good mid- and long-term clinical benefits.

Sodium hyaluronate for the treatment of chronic shoulder pain associated with glenohumeral osteoarthritis: a multicenter, randomized, double-blind, placebo-controlled trial. J Shoulder Elbow Surg 2013; 22:584-94. [PMID: 23333168 DOI: 10.1016/j.jse.2012.10.040] [Citation(s) in RCA: 32] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/15/2012] [Revised: 10/17/2012] [Accepted: 10/17/2012] [Indexed: 02/01/2023]
Abstract
BACKGROUND Nonoperative treatments for glenohumeral osteoarthritis (GH-OA) are limited. Intra-articular therapy with sodium hyaluronate (HA) has been effective in treating OA of the knee. Therefore, we sought to evaluate the efficacy and safety of HA in treating chronic pain associated with GH-OA. METHODS This double-blind, randomized, controlled multicenter trial enrolled 300 patients with GH-OA: 150 received HA and 150 received phosphate-buffered saline (PBS) in 3 weekly injections and were evaluated over 26 weeks. Primary and secondary outcome measurements were visual analog scale (VAS) for pain and the percentage of Outcome Measures in Rheumatoid Clinical Trials-Osteoarthritis Research Society International (OMERACT-OARSI) high responders. RESULTS In HA and PBS intent-to-treat (ITT) patients, there was a mean improvement from baseline in VAS of 19.88 mm and 16.29 mm at week 26, respectively. Similarly, the percentage of OMERACT-OARSI high responders in the HA group was higher (40.8% vs 34.9%); however, neither difference was statistically significant (P = .1121 and P = .0690, respectively). In a subset of patients without concomitant shoulder pathologies, the differences of VAS and OMERACT-OARSI high-responder rates between groups were 4.0 mm and 8.37%, respectively, which reached statistical significance. Safety analyses showed comparable rates of adverse events between groups, and neither group reported serious treatment-related adverse events. CONCLUSIONS A numeric advantage, but without statistical significance, was found for HA ITT patients with GH-OA. Although data for a subset of HA patients without concomitant pathologies reached statistical significance, additional randomized trials are needed to confirm the clinical implication of this outcome.

Abstract
A total of 159 patients (84 women and 75 men, mean age of 53 (20 to 87)) with subacromial impingement were randomised to treatment with subacromial injections using lidocaine with one of hyaluronic acid (51 patients), corticosteroid (53 patients) or placebo (55 patients). Patients were followed up for 26 weeks. The primary outcome was pain on a visual analogue score (VAS), and secondary outcomes included the Constant Murley score, shoulder pain score, functional mobility score, shoulder disability questionnaire and pain-specific disability score. The different outcome measures showed similar results. After three, six and 12 weeks corticosteroid injections were superior to hyaluronic acid injections and only at six weeks significantly better than placebo injections. The mean short-term reduction in pain on the VAS score at 12 weeks was 7% (sd 2.7; 97.5% confidence interval (CI) 0.207 to 1.55; p = 0.084) in the hyaluronic acid group, 28% (sd 2.8; 97.5% CI 1.86 to 3.65; p < 0.001) in the corticosteroid group and 23% (sd 3.23; 97.5% CI 1.25 to 3.26; p < 0.001) in the placebo group. At 26 weeks there was a reduction in pain in 63% (32 of 51) of patients in the hyaluronic acid group, 72% (38 of 53) of those in the corticosteroid group and 69% (38 of 55) of those in the placebo group. We were not able to show a convincing benefit from hyaluronic acid injections compared with corticosteroid or placebo injections. Corticosteroid injections produced a significant reduction in pain in the short term (three to 12 weeks), but in the long term the placebo injection produced the best results.

Abstract
BACKGROUND This study assessed the hypothesis that injection of high-molecular weight hyaluronate in the treatment of subacromial impingement syndrome is effective and safe, compared with corticosteroid injection in the shoulder joint. METHODS One hundred five patients were allocated randomly into 2 groups: 1 group was injected once a week for 3 weeks with hyaluronate and the other group was injected once with corticosteroid. All injections were guided to the subacromial space by an ultrasonogram. Eighty patients were followed up for 12 weeks after the injection: 38 patients in the hyaluronate group and 42 patients in the corticosteroid group. The functional outcome was measured using the American Shoulder and Elbow Surgeons standardized shoulder assessment form (ASES). RESULTS The Visual Analogue Scale (VAS) score at 12 weeks was decreased significantly from 58.6 ± 19.3 to 24.6 ± 23.1 in the hyaluronate group (P < .0001) and from 57.2 ± 19.9 to 36.9 ± 26.5 (P < .0001) in the corticosteroid group. There was a significant difference in the VAS score between the hyaluronic acid group and corticoid group (P = .0180) at 12 weeks. The functional ASES scores in the hyaluronate and corticosteroid groups were increased from 17.6 ± 4.8 to 22.4 ± 6.5 and from 17.3 ± 4.9 to 21.7 ± 5.8, respectively, at 12 weeks (P = .4825). There was no difference in the number of patients requiring rescue medication between the hyaluronate group and corticosteroid group at 12 weeks (P = .9254). CONCLUSION A subacromial hyaluronate injection to treat impingement syndrome produces similar pain and functional improvement to corticosteroid at a short-term follow-up.

Abstract
Shoulder osteoarthritis affect about 32% of patients over 60 years. Conservative treatment are recommended to restore shoulder function while shoulder arthroplasty remains the standard treatment for severe osteoarthritis. When conservative therapies fail and surgical approach is precluded, viscosupplementation with HA may be the treatment of choice. Currently, there is minimal information available comparing the results of Hylan G-F 20 and corticosteroid injections for the treatment of shoulder osteoarthritis. Therefore, the purpose of this study was to examine the results of these two treatments at specific time points with validated outcome measurements. Retrospective comparative cohort study. The study population included 84 patients, 51 of whom treated with Hylan G-F 20 and 33 with a corticosteroid. Gleno-humeral osteoarthritis was graded according to Samilson-Prieto classification and rotator cuff was assessed with MRI. Both groups received three injections 1 week apart and were evaluated using a Visual Analog Scale (VAS) for pain and satisfaction, the Shoulder Pain and Disability Index (SPADI) and the Constant-Murley scale. Outcomes were registered at 1, 3, and 6 months. The Hylan G-F 20 group showed a significant pain reduction (P < 0.05), improvement in the Constant-Murley, SPADI scores (P < 0.05), and satisfaction (P < 0.01) at all three follow-up times. Pain, clinical scores, and subjective satisfaction in the corticosteroid group improved in the first post treatment month only (P < 0.05) compared with the baseline. Overall, lower clinical advantages were found in patients with greater degree of osteoarthritis and rotator cuff tears. Intra-articular injections with Hylan G-F 20 are effective in reducing pain for up to 6 months in gleno-humeral osteoarthritis whereas corticosteroids injections resulte in improvement at 1 month only. In patients with severe osteoarthritis and/or full-thickness, RC tears results tended to be worse.

Abstract
Sodium hyaluronate injection into the glenohumeral joint is a treatment option in the management of adhesive capsulitis of the shoulder. We hypothesized that a systematic review would demonstrate that intra-articular sodium hyaluronate injections would result in significant improvements in passive range-of-motion, shoulder and general clinical outcome measures, and pain scales at short- and mid-term follow-up. Multiple medical databases were searched for levels I–IV evidence with a priori defined specific inclusion and exclusion study criteria. Clinical outcome measures used included Constant score, VAS pain scores, Cho functional scores, JOA scores, and range-of-motion measurements. Seven studies were included (four Level I and three Level IV; 292 subjects, 297 shoulders). Mean subject age was 59.1 years and mean pre-treatment duration of symptoms was 7.3 months. 140 subjects underwent one or multiple hyaluronate injections (120 glenohumeral joint; 20 subacromial bursa). Clinical follow-up was mean 9.0 weeks. Sodium hyaluronate injection into the glenohumeral joint has significantly improved shoulder range-of-motion, constant scores, and pain at short-term follow-up following treatment of adhesive capsulitis. Isolated intra-articular hyaluronate injection has significantly better constant scores than control. Isolated intra-articular hyaluronate injection has equivalent clinical outcomes and range-of-motion compared to intra-articular corticosteroid injection. Intra-articular hyaluronate injection was safe, with no reported complications within the studies in this review. Sodium hyaluronate injection into the glenohumeral joint is a safe, effective treatment in the management of adhesive capsulitis of the shoulder. Short-term evidence indicates that clinical outcomes are better than control and equivalent to intra-articular corticosteroid injection.

Abstract
Objective To investigate the additive effect of sono-guided subacromial bursa injection of hyaluronate with steroid in patients with peri-articular shoulder disorders. Method This prospective randomized controlled trial involved 26 patients who had shoulder pain. Group A, consisting of 13 patients, was treated with a sono-guided subacromial bursa injection containing a mixture of 0.5% lidocaine (5 ml) and triamcinolone 40 mg (1 ml), followed by injection with sodium hyaluronate (2 ml) once a week for 3 weeks. The other 13 patients (Group B) were treated with a sono-guided subacromial bursa injection containing a mixture of 0.5% lidocaine (5 ml) and triamcinolone 40 mg (1 ml) once a week for 3 weeks. The effects were assessed using a visual analogue scale (VAS) of shoulder pain, active range of motion (AROM), shoulder function assessment scale (SFA), shoulder disability questionnaire (SDQ) at study entry and every week from first injection until 4 weeks after the 1st injection (= 2 weeks after 3rd injection). Results (1) Demographic features and all parameters measured before injection did not show a significant difference between the 2 groups. (2) Statistically significant improvements were shown in VAS, SFA, SDQ during the 1st, 2nd, and 4th week after the first injection in both groups (p<0.05). (3) SFA showed significant improvement at 1 week after injection only in group A (p<0.05). (4) AROM of internal rotation showed significant improvement at week 4 after the 1st injection only in group A (p<0.05). Conclusion Subacromial bursa injection of hyaluronate with steroid in patients with peri-articular shoulder disorders has additive effects on functional improvement of the affected shoulder, including the AROM of internal rotation.

Abstract
OBJECTIVE To assess if ultrasound (US)-guided viscosupplementation can reduce pain and improve function in elderly patients with cuff tear arthropathy. PATIENTS AND METHODS Ninety-three patients aged over 65 with grade 3 or above cuff tear arthropathy were included in this prospective open-label non-randomized trial. Institutional review board approval and informed consent were obtained. Thirty-three patients received intra-articular injections of sodium hyaluronate under US guidance. Sixty patients constituted the control group. Shoulder joint function was assessed with Constant scores (CS) and pain with a visual analogue scale (VAS). RESULTS Compared with controls, treated patients reported a significant decrease in symptoms at 1 (mean CS 66±3.1 vs 37±6.9; mean VAS 1.9±1.2 vs 6.9±2.2), 2 (mean CS 65±3.2 vs 35±7.2; mean VAS 1.7±1.2 vs 6.8±2.5), 3 (mean CS 66±3.4 vs 33 6.1; mean VAS 2.3±1.2 vs 6.6±1.9), and 4 (mean CS 62±3.0 vs 34±6.5; mean VAS 3.3±1.4 vs 7.8±3.1) months, p<0.001. After 5 months there were no differences. CONCLUSION US-guided viscosupplementation is a beneficial therapeutic option in the first months of treatment.

Abstract
HYPOTHESIS A randomized, double-blind, placebo-controlled study of sodium hyaluronate (ARTZ Dispo) treatment was performed in 51 patients with rotator cuff lesions without complete tears. We hypothesized that ARTZ Dispo would render better results than the placebo. MATERIALS AND METHODS Twenty-five patients (ARTZ Dispo group) had injections of 25 mg/wk of sodium hyaluronate into the subacromial bursa for 5 consecutive weeks. Twenty-six patients (placebo group) were given 2.5 mL of normal saline solution with the same injection protocol as the ARTZ Dispo group. No significant difference in age, height, weight, gender, vocation, involved shoulder, duration of symptoms, baseline Constant score, or visual analog scale (VAS) score existed between the 2 groups. RESULTS The 2 groups did not significantly differ with regard to Constant scores, VAS scores, or global improvement assessments 1 week after injections. The ARTZ Dispo group had a better Constant score (P = .0095) and VAS score (P = .0018) than the placebo group 6 weeks after treatment. Patients in the placebo group were given 5 sodium hyaluronate injections, rather than placebo, after disclosure of the blind list, if they wished. Forty-one patients who underwent hyaluronate injection exhibited a significantly improved Constant score, from 64.0 +/- 11.7 at baseline to 88.9 +/- 10.4 (P < .0001), and a significantly improved VAS score, from 6.4 +/- 1.3 to 1.5 +/- 1.6 (P < .0001), at a mean follow-up of 33.1 months. No significant adverse effect was noted. CONCLUSIONS Subacromial injections of sodium hyaluronate are effective in treating rotator cuff lesions without complete tears.

Abstract
There is a growing body of evidence supporting the use of hyaluronan (HA) in patients with adhesive capsulitis of the shoulder, although the mechanisms of the effect have not yet been clarified. This in vitro study examined the effects of HA on glenohumeral synovial/capsular fibroblasts (GSCFs) from patients with adhesive capsulitis of the shoulder. The study subjects were seven patients with primary or secondary adhesive capsulitis of the shoulder (average age: 55 years; range: 42-65). Synovial/capsular specimens were obtained from the rotator interval of each patient during arthroscopy. Part of the tissue specimen was used for histological analysis. The remainder of the tissue was prepared for cell culture. Various concentrations of HA (0.0-4.0 mg/mL) were added to the monolayer-cultured GSCFs from these patients. Histological analysis consistently demonstrated chronic nonspecific inflammation with synovial hyperplasia, proliferation of vessels and fibroblasts, and increased amount of extracellular matrix. Treatment with HA at various concentrations significantly and dose-dependently inhibited cell proliferation and decreased the expression levels of mRNA for adhesion-related procollagens and cytokines. Pretreatment with OS/37 did not reverse the inhibitory effect of HA. These results suggest that HA modulates cell proliferation and expression of the mRNA of adhesion-related procollagens and cytokines in GSCFs, preventing the progression of adhesion formation in patients with adhesive capsulitis of the shoulder.

Abstract
Hyaluronate intraarticular injections are widely used for treatment of pain associated with osteoarthritis of the knee, but there is no published literature on its use in osteoarthritis of the hand. We describe an open-label, baseline-controlled pilot study in which 5 weekly injections of 10 mg sodium hyaluronate (molecular weight 500-730 kDa) in 1 mL was used to treat 16 patients with osteoarthritic first metacarpal-carpal (MC-C) joints. The injections were performed easily and were well tolerated. Mean pain score at 5 months after the last injection, on a 10-point visual analog scale, decreased from 4.74 to 2.56 at rest. Pain on use decreased from 5.91 to 4.33. Pinch strength and a short questionnaire on hand function did not significantly change. The results of this small pilot study suggest that intraarticular injections into the first MC-C joint are easily administered, well tolerated, and could be an effective treatment option for patients with osteoarthritis of this joint. Further investigation using larger, blind controlled clinical studies are warranted.

Intra-articular hyaluronic acid viscosupplementation is gaining popularity as a treatment option in the nonoperative management of patients with osteoarthritis. Recent clinical studies have demonstrated that the anti-inflammatory, anabolic, and chondroprotective actions of hyaluronic acid reduce pain and improve patient function. With evidence mounting in support of the efficacy of this treatment modality for patients with osteoarthritis, its potential use in additional patient populations and for other pathologies affecting the knee is being investigated. The current article reviews the use of intra-articular hyaluronic acid viscosupplementation in the management of knee osteoarthritis and presents the potential for expanding its indications for other joints and alternative patient subpopulations. Additionally, future directions for the use of hyaluronic acid and areas of active research are discussed.

Abstract
OBJECTIVE To assess the effects of steroid plus hyaluronate injections for scapulothoracic bursitis in patients with scapular pain. DESIGN Prospective open-label unicenter trial with a 3-month follow-up. SETTING University rehabilitation hospital. PARTICIPANTS Twenty-two cases of suspected scapulothoracic bursitis. INTERVENTION Injections into scapulothoracic bursa were performed with steroid plus hyaluronate. Injections were administered once a week for 3 weeks. MAIN OUTCOME MEASURES Visual analog scale (VAS), Rubin scale, adverse events, and injection-associated complications. RESULTS Mean outcome scores at 3-month follow-up visits showed significant improvements versus baseline (mean VAS increased from 7.8 to 2.2) (P<.05). Furthermore, mean VAS scores at 1, 2, and 3 weeks after treatment commencement showed significant improvements versus baseline (P<.05). No serious complication occurred during the study. CONCLUSIONS Scapulothoracic bursitis should be considered when treating patients with perimarginal scapular pain or subscapular pain. Our findings show that steroid plus hyaluronate injections into the scapulothoracic bursa provide an effective means of treating patients with scapulothoracic bursitis.

Abstract
INTRODUCTION Osteoarthritis (OA) is a disease of the synovial joints and is the most common cause of chronic pain in the elderly. One of the treatment modalities for OA of the hip is viscosupplementation (VS). Today there are several different formulations of viscosupplements produced by different manufactures of different molecular weights. The objective of this review is to asses the efficacy of VS treatment of hip OA osteoarthritis in the current literature. MATERIAL AND METHODS The following databases were searched: Medline (period 1966 to November 2006), Cochrane Database of Systematic Reviews (1988 to November 2006), Cochrane Clinical Trial Register (1988 to November 2006), Database of Abstracts on Reviews and Effectiveness, Current Controlled Trials, National Research Register and Embase (January 1988 to November 2006). The search terms [osteoarthritis, hip (joint), viscosupplementation, hyaluronic acid, hyaluronan, sodium hyaluronate and trade names] were applied to identify all studies relating to the use of VS therapy for OA of the hip joint. RESULTS Sixteen articles concerning the efficacy of a total of 509 patients undergoing VS treatment for hip OA were included. Twelve European studies, three Turkish studies and one American study with Levels of Evidence ranging from I to IV evaluated the following products: Hylan G-F 20, Hyalgan, Ostenil, Durolane, Fermatron and Orthovisc. Heterogeneity of included studies did not allow pooled analysis of data. DISCUSSION Despite the relatively low Level of Evidence of the included studies, VS performed under fluoroscopic or ultrasound guidance seems an effective treatment and may be an alternative treatment of hip OA. Intra-articular injection of (derivatives of) HA into the hip joint appears to be safe and well tolerated. However, VS cannot be recommended as standard therapy in hip OA for wider populations, and therefore the indications remain a highly individualised matter.

Abstract
A growing body of evidence supports use of intraarticular hyaluronic acid (HA) injection in patients with rotator cuff disease. However, the mechanism of its anti-inflammatory action has not been clarified. We examined the effects of HA on the expression of mRNAs for proinflammatory cytokines (IL-1beta, IL-6, and TNF-alpha and COX-2/PGE(2) production in IL-1-stimulated subacromial-synovium fibroblasts (SSF) derived from patients with rotator cuff disease. Various concentrations of HA were added to monolayer SSF cultures in the presence of IL-1beta. Gene expression levels were analyzed by quantitative real-time reverse transcription-polymerase chain reaction. Intracellular production of COX-2 was identified by Western blotting. PGE(2) concentrations in the culture media were measured by ELISA. CD44 blocking with OS/37 was performed to investigate the mechanism of action of HA. Immunofluorescence cytochemistry confirmed binding of HA and the presence of CD44 on SSF. Exogenous HA significantly and dose-dependently decreased expression of proinflammatory cytokine mRNAs and COX-2/PGE(2) production in IL-1-stimulated SSF. Pretreatment with OS/37 reversed the inhibitory effects of HA. These results provide a basis for explaining why HA is effective for the treatment of rotator cuff disease.

Abstract
BACKGROUND Presently, there are no approved nonoperative therapies for the ongoing treatment of persistent shoulder pain. Preliminary data suggest that intra-articular sodium hyaluronate injections may be beneficial for the treatment of persistent shoulder pain resulting from various etiologies. The present study evaluated the efficacy and safety of sodium hyaluronate (Hyalgan; molecular weight, 500 to 730 kDa) for these patients. METHODS Six hundred and sixty patients with persistent shoulder pain and limitation resulting from glenohumeral joint osteoarthritis, rotator cuff tear, and/or adhesive capsulitis who had had a failure of conventional therapy were enrolled in this double-blind, randomized, phosphate-buffered saline solution-controlled study, and 456 patients completed twenty-six weeks of follow-up. Patients were randomized to receive either five weekly intra-articular injections of sodium hyaluronate, three weekly intra-articular injections of sodium hyaluronate followed by two weekly intra-articular injections of saline solution, or five weekly intra-articular injections of saline solution. The main outcomes were improvement in terms of shoulder pain on movement at thirteen weeks after the initiation of treatment (as assessed with use of a 100-mm visual analog scale) and the treatment effect throughout twenty-six weeks. RESULTS For the overall intent-to-treat population, patients who were managed with sodium hyaluronate had greater pain relief than controls did; significant differences were noted at Week 7 (for the five-injection hyaluronate group), Week 17 (for the three and five-injection hyaluronate groups), and Week 26 (for the three-injection hyaluronate group). Analysis of the stratified populations clearly established that this effect was due to benefits experienced by the patients with osteoarthritis. The treatment effect through twenty-six weeks was significant in patients with osteoarthritis in the three-injection (p = 0.003) and five-injection (p = 0.002) groups, with no significant difference for either regimen in patients without osteoarthritis. The safety profile was very favorable, with no product-related serious adverse effects and no between-group differences for any reported adverse event. CONCLUSIONS Although the primary end point of this study (that is, improvement in terms of shoulder pain at thirteen weeks) was not achieved, the overall findings, including secondary end points, indicate that sodium hyaluronate (500 to 730 kDa) is effective and well tolerated for the treatment of osteoarthritis and persistent shoulder pain that is refractory to other standard nonoperative interventions.

Abstract
BACKGROUND While hylan G-F 20 is an approved therapy for the treatment of knee osteoarthritis, there are few reports of its use in shoulder osteoarthritis. HYPOTHESIS Hylan G-F 20 can reduce pain and improve function in patients with glenohumeral osteoarthritis. STUDY DESIGN Case series; Level of evidence, 4. METHODS Thirty consecutive patients with idiopathic glenohumeral osteoarthritis who failed to respond to standard conservative measures were enrolled. Patients received 3 weekly intra-articular hylan G-F 20 injections in their affected shoulder and completed a visual analog scale for pain, the UCLA score, and the Simple Shoulder Test at baseline and at 1, 3, and 6 months after the third injection. RESULTS Of the 30 patients, 3 withdrew during the washout period before treatment; the remaining patients (17 men and 10 women) had an average age of 62 years. The mean baseline visual analog scale score was 54, UCLA score was 15.7, and Simple Shoulder Test score was 5.7 (of 12 possible "yes" responses). At the 6-month follow-up, hylan G-F 20 significantly improved visual analog scale (mean 30, P < .001), UCLA (mean 24, P < .001), and Simple Shoulder Test (7.6 "yes" responses, P < .001) scores. More patients slept comfortably after treatment (56%) versus before treatment (15%). Nine patients had a visual analog scale improvement >40 points after 6 months. No device-related adverse events were observed. CONCLUSION Hylan G-F 20 may have a beneficial therapeutic effect on some symptomatic patients with glenohumeral osteoarthritis.

Abstract
PURPOSE In this study we evaluated the effect and safety of intra-articular injection of hyaluronic acid in 19 consecutive elbows with post-traumatic osteoarthritis. METHODS In 18 patients (10 male and 8 female patients; mean age, 45.6 years [SD, 15.0 years]), 3 injections of sodium hyaluronate were given within 4 weeks at regular intervals. Evaluation took place just before the first injection, as well as after 3 and 6 months, and consisted of the Elbow Function Assessment Score, the Functional Rating Index of Broberg and Morrey, and the Modified Andrews Elbow Scoring System. Pain was also assessed by means of visual analog scales. RESULTS Viscosupplementation resulted in slight, short-term pain relief and a very limited decrease in activity impairment at evaluation after 3 months. After 6 months, no beneficial effects were noticed in any of the 19 injected elbows. Other parameters were not influenced by treatment with viscosupplementation at any time. Systemic or local adverse effects did not occur. CONCLUSIONS Because the use of viscosupplementation for the treatment of post-traumatic osteoarthritis of the elbow provides only slight, short-term pain relief and a very limited decrease in activity impairment and the other parameters were not modified, we believe that viscosupplementation is not suitable for this indication. LEVEL OF EVIDENCE Level IV, therapeutic case series.

Abstract
The aim of this study was to compare the efficacy of sodium hyaluronate (SH) injection with the most common treatment methods, intraarticular steroid injection and physical therapy modalities in patients with adhesive capsulitis (AC). A total of 95 shoulders of 90 patients were included in the study and were randomized in four groups. The patients were treated with SH injection (group 1), triamsinolone acetonide (group 2) or physical therapy modalities (group 3). Group 4 patients were served as controls. Pain severity, passive ranges of motion and functional considerations were measured before, and 15 days and 3 months after the treatments. In all treatment groups, there were significant improvements at both the 15th day and third month in all parameters (for each, p<0.001). The passive abduction values on the 15th day was found significantly higher in group 3 when compared with group 1 and controls (for each, p<0.001). At the third month, the passive abduction values of the groups 2 and 3 were improved when compared with the control group (p<0.001). Constant score was higher in group 3 on 15th day when compared with group 1. At the third month, all treatment groups were improved significantly compared with control group (p<0.001). We provided the best results in physical therapy modalities applied group for AC treatment. However, we think that SH injection may be administered as an alternative treatment method.

Abstract
Chronic painful shoulder is a common complaint, yet its initial pathogenesis may have multiple etiologies as well as multiple and perhaps distinct primary or secondary etiologies responsible for its final clinical presentation. While the clinical presentation of pain and limitation of motion is easily defined, there are no standardized criteria for the differential diagnosis of various chronic shoulder pain syndromes, much less a consensus on their treatment. At present, there are limited nonsurgical options and medications approved for the treatment of chronic painful shoulder, and, with limited exceptions, there are no definitive conclusions about the efficacy of these therapies based on controlled clinical studies reported in the literature. There is a clear clinical need for local nonsurgical treatments that are safe and effective for chronic painful conditions. In this article, an attempt is made to review the diagnoses associated with chronic shoulder pain and some of the limited data that exist so as to suggest a therapeutic algorithm.

Abstract
The use of hyaluronans for the treatment of pain in patients with osteoarthritis of the knee is well established. There are growing data to suggest that they may also alter the rate of disease progression. Reviewed here are preliminary data that also indicate a potential use for hyaluronans in the treatment of inflammatory arthropathies (e.g. acute joint trauma and fractures) that require long periods of immobilisation, and in tissue engineering for chondral defects. Although the trials that have investigated the use of hyaluronan therapy for the management of traumatic and degenerative musculoskeletal disorders seen in sports medicine have limitations in design and patient number, the results have been promising and suggest that larger controlled clinical trials are warranted.

Synovial response to intraarticular injections of hyaluronate in frozen shoulder: a quantitative assessment with dynamic magnetic resonance imaging. J Orthop Sci 2004; 9:230-4.

Abstract
To clarify the response of frozen shoulder (FS) to intraarticular injections of high-molecular-weight sodium hyaluronate (HA), a mixture of 2.5 ml of HA and 1.5 ml of 1% lidocaine was injected into the glenohumeral joint of 11 patients with FS, 8 of whom received five weekly injections. The patients were assessed using the Japanese Orthopaedic Association shoulder score (JOA score) before the first injection, 1 week after the first injection, and 1 week after the final injection. Following each clinical evaluation, the patients underwent dynamic magnetic resonance imaging enhanced with Gd-DTPA, and the coefficient of enhancement (CE) in the glenohumeral synovium was calculated, with the examiners blinded to the clinical information. The JOA score tended to be greater and the CE smaller after injection than before injection. The changes in the CE following both single and repeated injections were negatively correlated with changes in the JOA score. Thus, clinical improvement in patients with FS was associated with a decrease in the CE. Because the CE depends on the degree of synovitis, the therapeutic effect of intraarticular HA injection for FS results, at least in part, from suppression of synovitis in the glenohumeral joint through an antiinflammatory effect.

Abstract
OBJECTIVE To evaluate the efficacy and safety of oxaprozin in comparison with diclofenac in patients with periarthritis pain of the shoulder previously unsuccessfully treated with nonsteroidal anti-inflammatory drugs other than diclofenac and oxaprozin. METHODS In this open, multicentre, randomised, controlled study, eligible patients with periarthritis of the shoulder were randomised to receive either oxaprozin 1200 mg once daily (n = 49) or diclofenac 50 mg three times daily (n = 47). The treatment period was 15 +/- 1 days. The study was planned on a hypothesis of equivalence between the two study drugs. The primary study endpoint was the change from baseline at day 15 in the patient-assessed shoulder pain score. Secondary efficacy variables included investigator-assessed shoulder function, patient-assessed quality of life on the Short-Form-36 (SF-36) Acute Health Survey and both patients' and investigators' overall assessment of efficacy. RESULTS At day 15, the mean changes in shoulder pain score from baseline in the oxaprozin and diclofenac groups were -5.85 +/- SD 4.62 and -5.54 +/- SD 4.41, respectively. The difference between the two groups was not statistically significant, confirming the hypothesis of the study that oxaprozin is as effective as diclofenac. Investigator-assessed shoulder function improved in both groups but more so in the oxaprozin group (p = 0.028 at day 15). Quality of life as measured by SF-36 total score was also improved in both treatment groups, with a trend toward greater improvement in the oxaprozin group. Furthermore, a significantly more favourable effect on the SF-36 'mental health' item was observed in oxaprozin compared with diclofenac-treated patients at day 15 (p = 0.0202). As assessed by investigators, the overall efficacy of oxaprozin was superior to that for diclofenac at visit 3 (8 +/- 1 days) (p = 0.0067). Patients also assessed the overall efficacy of oxaprozin as superior to that of diclofenac at visits 3 (8 +/- 1 days) (p = 0.0235) and 4 (15 +/- 1 days) (p = 0.0272). Only six adverse events, all of which were mild or moderate in intensity and occurred in four diclofenac recipients, were observed in the study. CONCLUSIONS As expected, once-daily oxaprozin proved to be as effective as diclofenac three times daily in reducing the primary efficacy variable of patient-assessed shoulder pain score in patients with periarthritis of the shoulder refractory to previous treatments with other NSAIDs. Oxaprozin was shown to be superior to diclofenac in improving shoulder function and was considered by investigators and patients to have greater overall efficacy than diclofenac. In addition, oxaprozin showed a trend toward superior results in improving patients' quality of life compared with diclofenac. A trend towards better tolerability results for oxaprozin compared with diclofenac was also noted.
