Salis Z, Sainsbury A. Association of long-term use of non-steroidal anti-inflammatory drugs with knee osteoarthritis: a prospective multi-cohort study over 4-to-5 years. Sci Rep 2024; 14:6593. [PMID: 38504099 PMCID: PMC10950850 DOI: 10.1038/s41598-024-56665-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2023] [Accepted: 03/08/2024] [Indexed: 03/21/2024] Open
Abstract
This study examines the long-term impact of non-steroidal anti-inflammatory drugs (NSAIDs) on the progression of symptoms and structural deterioration of the joint in knee osteoarthritis. The study analyzes data from 4197 participants (8394 knees) across the Osteoarthritis Initiative (OAI), Multicenter Osteoarthritis Study (MOST), and Cohort Hip and Cohort Knee (CHECK) over 4-to-5 years. Adjustments were made for major covariates. We focussed on binary outcomes to assess the presence or absence of significant changes. We found that, relative to non-users, individuals using NSAIDs long-term were significantly more likely to experience aggravated symptoms exceeding the minimally clinically important difference, specifically, pain (OR: 2.04, 95% CI: 1.66-2.49), disability (OR: 2.21, 95% CI: 1.74-2.80), and stiffness (OR: 1.58, 95% CI: 1.29-1.93). Long-term users also faced a higher probability than non-users of having total knee replacement (OR: 3.13, 95% CI: 2.08-4.70), although no significant difference between long-term users and non-users was observed for structural deterioration in the knee joint (OR: 1.25, 95% CI: 0.94-1.65). While acknowledging the limitations of this study due to its observational design and the potential for bidirectional causality, these findings suggest that long-term NSAID use could accelerate the progression to total knee replacement by markedly exacerbating symptoms.

Nonsteroidal Anti-Inflammatory Drug Injections versus Steroid Injections in the Management of Upper and Lower Extremity Orthopedic Conditions: A Systematic Review with Meta-Analysis. J Clin Med 2024; 13:1132. [PMID: 38398445 PMCID: PMC10889729 DOI: 10.3390/jcm13041132] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2024] [Revised: 01/31/2024] [Accepted: 02/14/2024] [Indexed: 02/25/2024] Open
Abstract
BACKGROUND Although corticosteroid injections are an effective treatment for musculoskeletal pathologies, they may not be suitable for all patients. The purpose of this systematic review was to compare clinical outcomes between patients who received NSAID and corticosteroid injections for various orthopedic conditions. METHODS Medline, Embase, Web of Science, and Cochrane Central Register of Controlled Trials were searched, and meta-analyses were performed using a random-effects model for outcomes presented in three or more studies. Other studies were qualitatively analyzed. RESULTS A total of 28 articles with 2113 patients were included. A meta-analysis of five studies in patients with shoulder impingement syndrome demonstrated that there was no significant difference in the pain visual analogue scale (VAS) between subacromial NSAID injections and corticosteroid injections at 1 month [weighted mean difference (WMD) -0.244; 95% CI, -1.232 to 0.745; I2, 94.5%]. For patients with knee osteoarthritis, a meta-analysis of three studies demonstrated that there was no significant difference between intraarticular NSAID injections and corticosteroid injections in pain VAS at 1 month (WMD 0.754; 95% CI, -0.413 to 1.921; I2, 90.2%) and 3 months (WMD-0.089; 95% CI, -0.345 to 0.166; I2, 0%). A review of the studies assessing pain outcomes for hip osteoarthritis, adhesive capsulitis, and plantar fasciitis showed no significant differences between the NSAID and corticosteroid groups. CONCLUSION NSAID injections may be safe and effective alternatives to steroid injections, especially in shoulder impingement syndrome and knee osteoarthritis.

Reduction of systemic exposure and side effects by intra-articular injection of anti-inflammatory agents for osteoarthritis: what is the safer strategy? J Drug Target 2023; 31:596-611. [PMID: 37249274 DOI: 10.1080/1061186x.2023.2220083] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2023] [Revised: 03/03/2023] [Accepted: 04/05/2023] [Indexed: 05/31/2023]
Abstract
Osteoarthritis (OA) is a chronic degenerative joint disease associated with pain, inflammation, and cartilage degradation. However, no current treatment can effectively halt the progression of the disease. Therefore, the use of NSAIDs and intra-articular corticosteroids is usually recommended as the primary treatment for OA-associated pain and inflammation. However, there is accumulating evidence that the long-term use of oral NSAIDs and intra-articular corticosteroids can lead to a myriad of negative side effects. Although numerous efforts have been made to develop intra-articular formulations for NSAIDs, the systemic exposure of intra-articular injection of NSAIDs and its potential side effects have not been explicitly investigated. To ascertain the evident and potential side effects of intra-articular injection of anti-inflammatory agents, we have summarised in this review the systemic exposure, local side effects, and systemic side effects of intra-articular injections of anti-inflammatory agents, including NSAIDs and corticosteroids. For developing a safer treatment to fulfil the unmet long-term use needs of patients, a new therapy, which combines the locally active drug and a sustained-release formulation, has been proposed in this review.

Abstract
OBJECTIVES The purpose of this study was to systematically review the available evidence regarding any plausible deleterious effects of nonsteroidal anti-inflammatory drugs (NSAIDs) on chondrocytes, chondrocyte differentiation, and allograft or autograft incorporation after cartilage repair procedures. DESIGN Three databases (PubMed, Science Direct, and Cochrane Library) were screened for eligible studies: investigating the effects of NSAIDs on chondrocytes, chondrogenic differentiation, or allograft/autograft incorporation. This evaluation included studies of any level of evidence, written in English, reporting clinical or preclinical results, published in peer review journals and dealing with our topic. All articles evaluating the effects of NSAIDs on either osteoarthritic (OA) chondrocyte samples or OA chondrocyte models were excluded. Moreover, articles about bone healing in which allograft or autograft incorporation was not investigated were also excluded. Methodologic quality assessment was performed for in vivo animal studies according to ARRIVE guidelines, and risk of bias of each included study was identified using the ROBINS-I tool. RESULTS Eighteen studies were included in the review: 4 in vitro studies, 13 animal studies, and 1 human study. According to these studies NSAIDs have no detrimental effect on healthy mature chondrocytes; however, these drugs influence chondrocyte differentiation and graft incorporation and therefore may interfere with chondrogenesis and incorporation after transplantation of chondrocytes or osteochondral grafts. CONCLUSION The use of NSAIDs, systemic or local, after cartilage repair procedures should be avoided unless a substantial clinical benefit would otherwise be withheld from the patient. More human studies are needed to analyze the effect of NSAIDs on cartilage repair.

Abstract
Background As nonsteroidal anti-inflammatory drugs (NSAIDs) and steroids have similar effects, steroids can be avoided to reduce adverse effects. This study aimed to compare the differences in symptom improvement after subacromial injection of steroids or NSAIDs. Methods Sixty patients with rotator cuff syndrome for at least 3 months were enrolled and divided into steroid and NSAID groups. The steroid group received a mixture of 1 mL of triamcinolone acetonide (40 mg/mL) and 1 mL of lidocaine hydrochloride 2%, while the NSAID group received a mixture of 1 mL of Ketorolac Tromethamine (30 mg/mL) and 1 mL of lidocaine hydrochloride 2%. The patients were assessed before and at 3, 6, and 12 weeks after the procedure. Shoulder scores from visual analog scale (VAS), American Shoulder and Elbow Surgeons (ASES), and University of California Los Angeles (UCLA) were used for evaluation. Results Both groups showed improvements in the clinical outcomes. Overall VAS, ASES, and UCLA scores improved from 6.9, 32.7, and 16.0 before the procedure to 2.0, 1.2, and 1.1; 81.5, 87.6, and 88.5; and 29.7, 31.8, and 32.0 at weeks 3, 6, and 12 weeks after the procedure, respectively. Twenty-six patients (86.7%) in the steroid group and 28 (93.3%) in the NSAID group reported satisfactory treatment outcomes. There were no significant differences in the outcomes between the two groups (p=0.671). Conclusions Subacromial injection of NSAIDs for rotator cuff tendinitis with shoulder pain had equivalent outcomes with those of steroid injection at the 12-week follow-up.

Abstract
BACKGROUND Intra-articular corticosteroid injections have been widely used and are considered a mainstay in the nonoperative treatment of symptomatic knee osteoarthritis (OA). However, their increased use can have negative implications, including chondral toxicity and a high risk of infections. As a result, nonsteroidal anti-inflammatory drugs have been considered as an alternative. PURPOSE To determine the pain relief and safety of ketorolac versus a corticosteroid to supplement an intra-articular sodium hyaluronate injection for the treatment of symptomatic knee OA. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS A total of 84 patients with unilateral symptomatic knee OA receiving 5 weekly injections were enrolled in this retrospective study. Group A (n = 42) received 3 weekly intra-articular corticosteroid injections (0.5% lidocaine, 25 mg of triamcinolone acetonide, and 25 mg of sodium hyaluronate, followed by 2 weekly injections of 0.5% lidocaine and 25 mg of sodium hyaluronate), while group B (n = 42) received 5 weekly ketorolac injections (0.5% lidocaine, 10 mg of ketorolac, and 25 mg of sodium hyaluronate). The following parameters were used to evaluate pain relief and safety: visual analog scale (VAS) for pain, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and side effects before the injection and at 1, 2, and 5 weeks after treatment commencement as well as 3 months after the last injection. RESULTS Patients from both groups had a significant improvement in VAS and WOMAC scores from the first injection to final follow-up at 3 months. In the first week, the VAS score was lower in group A (P = .041), but no significant between-group differences were found for either the VAS or the WOMAC score at the other time points. Of the 42 patients in group A, 34 (81.0%) and 25 (59.5%) achieved successful outcomes at 5 weeks after treatment commencement and 3 months after the last injection, respectively. In group B, 32 (76.2%) and 24 (57.1%) patients achieved successful outcomes at 5 weeks after treatment commencement and 3 months after the last injection, respectively. At final follow-up, no significant difference was found in the successful treatment rate between the groups (P = .825). CONCLUSION The current study demonstrated that intra-articular ketorolac and corticosteroid injections produce the same pain relief and functional improvement.

The effects of intra-articular injection of ibuprofen on knee joint cartilage and synovium in rats. ACTA ORTHOPAEDICA ET TRAUMATOLOGICA TURCICA 2019; 53:292-296. [PMID: 30982756 PMCID: PMC6739263 DOI: 10.1016/j.aott.2019.03.013] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/05/2018] [Revised: 11/18/2018] [Accepted: 03/17/2019] [Indexed: 12/22/2022]
Abstract
Objective The aim of this animal study was to investigate the short and long-term local histomorphologic effects and the utility of intra-articular application of ibuprofen. Methods Forty-six Wistar Albino rats were used in the study. The rats were randomized into 5 groups of 8 and a sham group of 6. The 40 rats in the study groups were anaesthetised with 60 mg/kg of ketamine, then 0.25 ml ibuprofen (25 mg) was injected to the right knee joint of each rat (ibuprofen group) and 0.25 ml 0.9% saline to the left knee joint as the control group. To the 6 rats in the sham group, only puncture was applied to both knee joints. The rats in each of the 5 study groups were sacrificed on days 1, 2, 7, 14 and 21 respectively. The histomorphologic changes were graded on a 6-point scale regarding inflammation of the synovia, cartilage tissue, and subchondral bone. Inflammation scores were compared using the Mann Whitney U-test and comparisons of the sacrifice day and drug used were evaluated with the Kruskal Wallis test. The p values below 0.05 were considered as significant. Results Statistically significant difference was found between the ibuprofen injected knees (10/40) and the saline injected (0/40) and sham knees (0/12) in respect of hematoma positivity (p = 0.002). Significantly higher inflammation scores were found in ibuprofen injected knees on the 1st, 2nd, 7th and 14th days compared to controls and sham (p < 0.05). Inflammation scores were similar in ibuprofen injected knees with and without hematoma (p > 0.05). Inflammation of the ibuprofen injected group was most severe on day one and the severity of inflammation reduced gradually throughout the 3 weeks. Conclusion Our results show that intra-articular injection of ibuprofen can cause intra-articular hematoma. It also leads to transient inflammation of the synovia that is more severe in the early period, which gradually recovers.

Abstract
Intra-articular (IA) injection of hyaluronic acid (HA) in combination with nonsteroidal anti-inflammatory drugs, such as ketorolac (KL), have been clinically investigated to provide more rapid and profound pain relief in patients with osteoarthritis. However, its safety, local tolerance, and potential for pharmacokinetic interaction have not been assessed. In this study, the pharmacokinetics and toxicity of a combination of HA and KL were evaluated in normal rats following four-week repeated-dose injection. Rats received HA or KL alone at 4 mg/kg or 16 mg/kg, respectively, or HA/KL combination at 4/4 mg/kg, 4/8 mg/kg, or 4/16 mg/kg on a weekly basis. The rats exhibited temporal, reversible changes in hematology, serum chemistry, and urinalysis caused primarily by KL treatment. No deleterious effects were observed on the joint following repeated IA HA/KL administration, which showed only minimal to mild levels of temporary inflammatory changes in synovial membrane. The plasma KL level following IA injection rose as fast as that of intra-muscular injection, with no alteration with the co-administered HA. In conclusion, repeated IA administration of HA/KL combination was tolerated well in normal rats, encouraging future studies of IA injection of HA/KL combination on osteoarthritis-induced animal models and even patients.

Abstract
Background To date, a regional approach using local anesthetics has become a popular analgesic method for arthroscopy. The optimal postoperative analgesia method for shoulder arthroscopy is still debated. Objective This study was designed to evaluate the effect and safety of using ketorolac in combination with a multimodal drug regime (ropivacaine, morphine, and triamcinolone acetonide) after shoulder arthroscopy. Methods A total of 60 patients were included in a pilot study and patients were randomized into an experimental group (n=30) and a control group (n=30). The following parameters were used to evaluate pain relief levels postoperatively: the Visual Analog Scale (VAS) at 1, 3, 6, 12, 24, and 48 hours postoperatively, morphine consumption, and initial analgesic desired time. Complications were also recorded. Results Except for 1 hour postoperatively, patients in the experimental group experienced lower VAS scores during the first 48 hours postoperatively (P<0.05). The VAS score in both groups increased after 3 hours postoperatively and peaked at 12 hours postoperatively (2.54±0.86 vs 3.25±1.18). The VAS scores on movement in the experimental group were lower than those in the control group at 24 or 48 hours postoperatively (P=0.004, 0.001). A total of 18 (60.0%) patients in the experimental group required no additional analgesia, compared with 10 (33.3 %) in the control group (P=0.035). The mean rescue analgesia was 11.40±5.56 mg in the experiment group, while 16.57±8.48 mg in the control group (P=0.016). The initial analgesic desired time was delayed significantly in the experimental group (16.50±14.57 hours vs 8.9±6.32 hours, P=0.000). Conclusion Adding ketorolac to intra-articular injection analgesia is a safe and effective method to improve pain relief after shoulder arthroscopy, and further prospective controlled trials are necessary to allow definite treatment recommendations.

Are non-steroidal anti-inflammatory drug injections an alternative to steroid injections for musculoskeletal pain?: A systematic review. J Orthop 2018; 15:812-816. [PMID: 30140124 DOI: 10.1016/j.jor.2018.08.022] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/04/2018] [Accepted: 08/05/2018] [Indexed: 11/20/2022] Open
Abstract
Background Given the potential side effect profile of steroids, the need for an alternative injectable anti-inflammatory is needed. The purpose of this systematic review was to compare corticosteroid injections with non-steroidal anti-inflammatory drug (NSAID) injections for musculoskeletal pain. Methods Reviewers with methodological and content expertise searched three databases: PUBMED, Medline and EMBASE. Two blinded reviewers searched, screened, and evaluated the data quality. Data was abstracted in duplicate. Agreement and descriptive statistics are presented. Results Four studies were included. All four studies found no statistically significant differences in improvements on the visual analog scale. The follow-up period within the four studies ranged between 2 weeks and 3 months. No statistically significant differences were demonstrated between the two groups with regards to functional outcomes. Interpretation The studies reviewed, while limited in quantity, show that compared with corticosteroids, NSAIDs provide equivalent, if not better, pain relief from the musculoskeletal ailments assessed. Further, there is weak evidence supporting a lower recurrence rate of symptoms with NSAIDs when compared to corticosteroids. There is a need for more long-term high-quality studies on this topic. Level of evidence Level II (Systematic review of Level II and III studies).

Abstract
OBJECTIVE Intra-articular steroid injection has been widely used in the management of symptomatic osteoarthritis; however, its frequent use is avoided since there is an increase in the incidence of articular infection and several mechanical side effects such as cartilage breakdown and loss of elasticity of the articular cartilage. For these reasons, nonsteroidal anti-inflammatory drugs instead of corticosteroids can be considered for intra-articular injection. On this basis, we investigated the effects and safety of ultrasound-guided intra-articular ketorolac versus corticosteroid injection for patients with osteoarthritis of the hip. MATERIALS AND METHODS This retrospective study included 98 patients with diagnoses of hip osteoarthritis who underwent ultrasound-guided intra-articular ketorolac or corticosteroid injection. Fifty patients who received ultrasound-guided intra-articular corticosteroid injection were administered a mixture of 0.5% lidocaine and triamcinolone. Forty-eight patients who received ultrasound-guided intra-articular ketorolac injection were administered 0.5% lidocaine and ketorolac. Outcome measurement was assessed using the Harris hip score and verbal numeric pain scale, which were evaluated before the injections and at 1, 3 and 6 months following the injection. Univariate analysis (using the x (2) test) and multiple logistic regression analysis were performed to evaluate the relationship between the possible outcome predictors (injected medications, patients' age, gender, pain duration and Kellgren-Lawrence classification) and the therapeutic effects. RESULTS The Harris hip score and verbal numeric pain scale were improved at 1, 3 and 6 months after the injection in both groups. No statistical differences in the Harris hip score and verbal numeric pain scale were observed between the groups. The success rate was also not significantly different among the time periods of 1, 3 and 6 months. Multiple logistic regression and univariate analysis showed that injected medications patients' age, gender, pain duration and Kellgren-Lawrence classification were not independent predictors of successful outcome at midterm follow-up. CONCLUSION The treatment of osteoarthritis of the hip with intra-articular ketorolac injection is as effective as that with intra-articular corticosteroid injection. Intra-articular ketorolac injection can be considered useful for patients with contraindications to using corticosteroids.

Abstract
Administration of intra-articular medications, including corticosteroids and analgesics, is common clinical practice for knee pathology and dysfunction. Non-steroidal anti-inflammatory drugs (NSAIDs) are another category of medication commonly prescribed for their analgesic and anti-inflammatory properties. Recent studies demonstrated the efficacy of injectable NSAIDs in the treatment of intra-articular pathology and postoperative analgesia. However, little data exist regarding the safety of intra-articular injection, despite the increase in its application. Therefore, we investigated the effects of intra-articular NSAID injection on articular cartilage, the anterior cruciate ligament (ACL), and joint function in the rat. Sixty-four Sprague-Dawley rats were divided into either saline (SAL) or ketorolac (NSAID) tibiofemoral single injection treatment groups. Animals were euthanized at 2, 7, 28, and 84 days post-injection for histological and mechanical analyses. Additionally, a subset of animals underwent longitudinal ambulatory evaluation to determine joint functional properties. We hypothesized that intra-articular ketorolac injection would result in no detrimental mechanical, histological, or functional changes. No differences were reported between the NSAID and SAL groups in any of the parameters measured at any time point, demonstrating the potential safety of intra-articular NSAID administration. Therefore, NSAID injection could be further considered for clinical application in humans.

The effect of ketorolac tromethamine, methylprednisolone, and platelet-rich plasma on human chondrocyte and tenocyte viability. Arthroscopy 2013; 29:1164-74.

Abstract
PURPOSE The purpose of this study was to evaluate the effect on cell viability of the isolated and combined use of allogeneic platelet-rich plasma (PRP) and ketorolac tromethamine on human chondrocytes and tenocytes in a highly controlled in vitro environment. METHODS PRP was produced from 8 subjects. Human chondrocytes (Lonza, Hopkinton, MA) and tenocytes isolated from samples of the long head of the biceps tendons were treated in culture with PRP, ketorolac tromethamine, and methylprednisolone, both alone and in combination. Control samples were treated in media containing 2% or 10% fetal bovine serum (FBS). Cells were exposed for 1 hour. Luminescence assays were obtained to examine cell viability after 24 hours and long-term effects on cell viability after 120 hours. Radioactive thymidine assay was used to measure proliferation after 120 hours. RESULTS For chondrocytes, cell viability (120 hours) increased significantly with the treatment of PRP alone (43,949 ± 28,104 cells; P < .001) and with the combination of ketorolac tromethamine and PRP (43,276 ± 31,208; P < .001), compared with the 2% FBS group (7,397 ± 470). Cell viability decreased significantly after exposure to methylprednisolone (1,323 ± 776; P < .001) and its combination with PRP (4,381 ± 5,116; p < .001). For tenocytes, cell viability (120 hours) was significantly higher with the treatment of PRP (61,287 ± 23,273; P < .001) and the combined treatment of ketorolac tromethamine and PRP (52,025 ± 17,307; P < .001), compared with the 2% FBS group (23,042 ± 2,973). Cell viability decreased significantly after exposure to methylprednisolone (3,934 ± 1,791; P = .001) and its combination with PRP (5,201 ± 2,834; P = .003), compared with 2% FBS. CONCLUSIONS Tendon and cartilage cells showed increased cell viability after an exposure to allogeneic PRP and ketorolac tromethamine. Exposure to methylprednisolone alone decreased cell viability, and addition of PRP could partially reverse this negative effect. CLINICAL RELEVANCE Intra-articular injections of pain-modifying or anti-inflammatory drugs are routinely given in orthopaedic practice. Among the many agents available for intra-articular injection, corticosteroids and local anesthetics are the most common in clinical practice. Potential detrimental side effects of intra-articular injections of corticosteroids and local anesthetics have prompted investigation into alternative treatment options such as combinations of PRP and ketorolac tromethamine. In vitro evaluation of their effect on cell viability might build a basis for further translational research and clinical application.

Abstract
Chronic neck pain affects up to 70% of persons, with the facet joint being the most common source. Intra-articular injection of the non-steroidal anti-inflammatory drug ketorolac reduces post-operative joint-mediated pain; however, the mechanism of its attenuation of facet-mediated pain has not been evaluated. Protease-activated receptor-1 (PAR1) has differential roles in pain maintenance depending on the type and location of painful injury. This study investigated if the timing of intra-articular ketorolac injection after painful cervical facet injury affects behavioral hypersensitivity by modulating spinal astrocyte activation and/or PAR1 expression. Rats underwent a painful joint distraction and received an injection of ketorolac either immediately or 1 day later. Separate control groups included injured rats with a vehicle injection at day 1 and sham operated rats. Forepaw mechanical allodynia was measured for 7 days, and spinal cord tissue was immunolabeled for glial fibrillary acidic protein (GFAP) and PAR1 expression in the dorsal horn on day 7. Ketorolac administered on day 1 after injury significantly reduced allodynia (p=0.0006) to sham levels, whereas injection immediately after the injury had no effect compared with vehicle. Spinal astrocytic activation followed behavioral responses and was significantly decreased (p=0.009) only for ketorolac given at day 1. Spinal PAR1 (p=0.0025) and astrocytic PAR1 (p=0.012) were significantly increased after injury. Paralleling behavioral data, astrocytic PAR1 was returned to levels in sham only when ketorolac was administered on day 1. Yet, spinal PAR1 was significantly reduced (p<0.0001) by ketorolac independent of timing. Spinal astrocyte expression of PAR1 appears to be associated with the maintenance of facet-mediated pain.

Abstract
HYPOTHESIS The objective of this study was to compare the efficacy of subacromial injection of triamcinolone compared to injection of ketorolac in the treatment of external shoulder impingement syndrome. METHODS Thirty-two patients diagnosed with external shoulder impingement syndrome were included in this double-blinded randomized controlled clinical trial. Each patient was randomized into the steroid group or nonsteroidal anti-inflammatory drugs (NSAID) group. The steroid syringe contained 40 mg triamcinolone; and the NSAID syringe contained 60 mg ketorolac. Each patient was evaluated in terms of arc of motion, visual analog scale (VAS) for evaluating pain, and the UCLA (The University of California at Los Angeles) shoulder rating scale. RESULTS At 1 month follow-up, both treatment arms resulted in increased range of motion and decreased pain. The steroid group decreased in active abduction while the NSAID group increased (steroid: 134°, NSAID: 151°, P = .03). The mean improvement in the UCLA shoulder rating scale at 4 weeks was 7.15 for the NSAID group and 2.13 for the steroid group (P = .03). Subgroup analysis of the UCLA scale demonstrated an increase in both forward flexion strength (P = .04) and patient satisfaction (P = .03) in the NSAID group. No significant difference could be seen in all other outcome measures. CONCLUSION In this study, an injection of ketorolac resulted in greater improvements in the UCLA shoulder rating scale than an injection of triamcinolone at 4 weeks follow-up. While both triamcinolone and ketorolac are effective in the treatment of isolated subacromial impingement, ketorolac appears to have equivalent if not superior efficacy; all the while decreasing patient exposure to the potential side-effects of corticosteroids.

Abstract
Chronic neck pain is one of the most common musculoskeletal disorders in the US. Although biomechanical and clinical studies have implicated the facet joint as a primary source of neck pain, specific cellular mechanisms still remain speculative. The purpose of this study was to investigate whether a mediator (activating transcription factor; 4ATF4) of the integrated stress response (ISR) is involved in facet-mediated pain. Holtzman rats underwent C6/C7 facet joint loading that produces either painful (n=16) or nonpainful (n=8) responses. A sham group (n=9) was also included as surgical controls. Behavioral sensitivity was measured and the C6 dorsal root ganglia (DRGs) were harvested on day 7 to evaluate the total and neuronal ATF4 expression. In separate groups, an intra-articular ketorolac injection was administered either immediately (D0 ketorolac) or 1 day (D1 ketorolac) after painful facet joint loading. Allodynia was measured at days 1 and 7 after injury to assess the effects on behavioral responses. ATF4 and BiP (an indicator of ISR activation) were separately quantified at day 7. Facet joint loading sufficient to elicit behavioral hypersensitivity produced a threefold increase in total and neuronal ATF4 expression in the DRG. After ketorolac treatment at the time of injury, ATF4 expression was significantly (P<0.01) reduced despite not producing any attenuation of behavioral responses. Interestingly, ketorolac treatment at day 1 significantly (P<0.001) alleviated behavioral sensitivity at day 7, but did not modify ATF4 expression. BiP expression was unchanged after either intervention time. Results suggest that ATF4-dependent activation of the ISR does not directly contribute to persistent pain, but it may sensitize neurons responsible for pain initiation. These behavioral and immunohistochemical findings imply that facet-mediated pain may be sustained through other pathways of the ISR.

Abstract
Tendonitis, tenosynovitis, and the arthritides are clinical problems commonly encountered in daily orthopaedic practice. Systemic anti-inflammatories, physical therapy, and local corticosteroid injections all are used as nonoperative treatments of these conditions. Systemic anti-inflammatory agents and local corticosteroid agents, however, can be associated with adverse effects that render them intolerable to some patients. As a preliminary study assessing the feasibility of local injection of nonsteroidal anti-inflammatory medication, the histological and biomechanical effects of local exposure of rabbit cartilage and tendon to injectable steroidal (corticosteroid) and injectable nonsteroidal anti-inflammatory agents (ketorolac tromethamine, KT) were determined. Thirty rabbits underwent bilateral knee joint, patellar tendon, and Achilles tendon injections with either normal saline, corticosteroid, or KT. Mechanical and histologic evaluation of the tissues was performed at 6 and 15 weeks after injection. Gross tendon adhesions were observed in more corticosteroid-treated specimens than those exposed to normal saline or KT. Microscopic evaluation of tendons revealed no significant differences among the three groups. Mild cartilage degenerative changes were noted across all groups. Evidence of cartilage necrosis was noted for the corticosteroid-treated group only. Tendons exposed to corticosteroid or KT demonstrated increased load and energy to failure, but exhibited no difference in material stiffness or strain. The use of an injectable nonsteroidal anti-inflammatory agent may be safe and even pose less threat to local tissues after intra-articular and peri-tendinous administration.

Abstract
In order to investigate if beta-endorphins anti-inflammatory effect in cartilage-damaging states is mediated via tumor necrosis factor-alpha (TNF-alpha) and interleukin-1 beta (IL-1 beta), we examined its influence on these two cytokines in vitro. Human articular chondrocytes were obtained from patients undergoing total knee arthroplasty and stimulated with beta-endorphin (60-6000 ng/ml). Protein levels of TNF-alpha and IL-1 beta were measured by ELISA in supernatants from articular chondrocyte cultures. beta-Endorphin significantly increased the levels of IL-1 beta for all concentrations used after 15 min incubation, and when stimulated with 600 and 6000 ng/ml after 24 h incubation. The opioid-induced increase in IL-1 beta was blocked by naltrexone in the group tested. TNF-alpha expression was also significantly stimulated by 60 and 600 ng/ml beta-endorphin after 15 min, an effect blocked by naltrexone in the group tested. These findings indicate that the mechanism of beta-endorphins anti-inflammatory influence in cartilage-damaging states is not apparently mediated via these two cytokines modulation.
