Description

Sodium hyaluronate (SH), similar to hyaluronic acid (HA), is a sticky, viscous, elastic solution which is injected into a knee joint to ease the pain from osteoarthritis (OA). This procedure is known as viscosupplementation or intra-articular (IA) injection and is approved by the Federal Drug Administration (FDA).

Sodium hyaluronate (SH) penetrates the articular cartilage surface, the synovial tissue, and the capsule of the joints. In the normally functioning joint, the HA (a normal element of synovial fluid in the human joint) lubricates the joint during low impact activities, such as resting or walking. During high impact activities, such as running, HA helps to prevent mechanical damage and decrease shock on the joint.

There are many types of arthritis (e.g., rheumatoid, degenerative, post-traumatic, autoimmune induced). The most common form is OA, also known as degenerative joint disease (DJD). While the exact cause is unknown, there are several possible causes, including injury, age, congenital predisposition, and obesity. In patients with OA, the elasticity and viscosity of the synovial fluid and the HA concentration is reduced, and this is characterized by the breakdown of the articular cartilage within the joint. This causes a reduction of the protective, lubricating, and shock absorbing properties of the synovial fluid. By injecting SH into the joint, the normal environment of the synovial fluid is restored. Currently, there is no curative therapy for OA, and thus the overall goal of management is to reduce pain and prevent disability.

A diagnosis of knee osteoarthritis (KOA) may be determined by utilizing the following Clinical Classification Criteria from the American College of Rheumatology (ACR). (1)

Sodium hyaluronate (SH), is used as an injectable for the knee joint, and is currently marketed as Euflexxa™, Hyalgan®, Orthovisc®, Supartz™, Synvisc®, Synvisc-One™, or Gel-One®. The FDA approvals are as a medical device, not as a drug classification to treat pain in osteoarthritis (OA) of the knee joint. For these devices, the patient must have failed to respond adequately to conservative therapy. This includes, but is not limited to, simple pain relievers, exercise, and physical therapy. The FDA approvals for SH are as follows:

  • Euflexxa (Nuflexxa, Viscosup) approved on December 3, 2004,
  • Hyalgan (Hyaluronan, Hylan G-F20, Hylan Gel-Fluid) approved on May 28, 1997,  
  • Orthovisc approved on February 5, 2004,
  • Supartz approved on January 24, 2001,
  • Synvisc (Hylan G-F20) approved on August 8, 1997, and
  • Synvisc-One (Hylan G-F20) approved on February 26, 2009.
  • Gel-One approved on March 22, 2013. (2)

Clinical trials continue as the use of sodium hyaluronate (SH) is being investigated for treatment in the shoulder and/or hip joints; FDA approval has not been determined for these indications.

Coverage

Viscosupplementation by intra-articular (IA) injections (a single, one-time dose, injection OR multiple injections done weekly) using a U.S. Food and Drug Administration (FDA)-approved sodium hyaluronate (hyaluronic acid) (SH) preparation may be considered medically necessary for patients who meet ALL of the following DOCUMENTED criteria:

  1. Symptomatic, painful osteoarthritis (OA) of the knee; AND
  2. Osteophytes of the knee OR OA of the knee, confirmed by imaging; AND
  3. Reports of pain interfering with functional activities (such as walking and/or standing) for a minimum of six months with morning stiffness lasting 30 minutes or less AND crepitus on knee motion;
  4. Cause of pain cannot be attributed to other forms of joint disease; AND,
  5. Failure to respond to a comprehensive treatment program for six months and meet any three of the following DOCUMENTED criteria:
    • Conservative therapy, which includes use of pharmacologic therapy (such as acetaminophen, a non-steroidal anti-inflammatory drug [NSAID] up to four times daily, topical anti-inflammatory preparations containing capsaicin cream applied to affected knee joint) for minimum of three months without functional relief, OR 
    • Physical therapy to the affected knee joint; OR
    • Participation in an exercise program; OR
    • Utilization of an orthotic device (such as a knee brace) applied to the affected knee joint; OR
    • Aspiration of the affected knee joint; OR
    • Injection(s) of IA steroids to the same affected knee joint; OR
    • The patient is unable to utilize conservative therapy due to adverse effects.

Repeat treatment cycle using an FDA-approved SH preparation may be considered medically necessary for patients who meet ALL of the following DOCUMENTED criteria:

Viscosupplementation by IA injections using sodium hyaluronate (SH) for the treatment of diseases of the knee that are not related to OA, including but not limited to chondromalacia patellae or osteochondritis dissecans, are considered experimental, investigational, and/or unproven.

Viscosupplementation by IA injections using SH for the treatment of OTHER joints (such as the foot, ankle, hip, spine, thumb, wrist, elbow, shoulder, and temporomandibular joint) are considered experimental, investigational, and/or unproven.

Rationale

In 1995, Scali, J.J., conducted an uncontrolled study of 75 patients with osteoarthritis (OA) of the knee who received five weekly intra-articular injections of 2-mL Hyalgan repeated every six months, for a total of 25 IA injections over two years. Over the course of the study, progressive reduction was noted in various symptoms, including pain, stiffness, and analgesic intake. There were no serious systemic side effects. (4) Kotz and Kolarz (5) conducted an open-label, multicenter study of 108 patients who received five weekly injections of Hyalgan, 14 of whom began a new treatment cycle after four to eight months due to pain recurrence. Six of these patients completed the second cycle follow-up of 12 months. Patients who received a second treatment cycle showed further improvement. There were no significant systemic side effects. In other international studies of both Synvisc and Hyalgan, multiple treatment courses have been reported, but the studies do not permit separate assessment of the effectiveness of multiple courses of therapy.

In 2005, a Cochrane review of viscosupplementation for OA of the knee was published that evaluated a total of 63 clinical trials identified from a literature review conducted through April 2004. Overall, the review concluded hyaluronic acid (HA) is safe and effective in improving pain, function, and global patient function in the treatment of OA of the knee. Included in the 63 trials evaluated for the review were 37 trials comparing HA and/or hylan products to placebo. The pooled analyses for these 37 trials demonstrated that HA treatment was more effective than placebo, most notably in the 5 to 13 weeks after treatment. Five trials were evaluated that compared hyaluronan to NSAIDs. In the analysis of this comparison, HA was found to be comparable in efficacy to NSAIDs. In nine trials comparing HA to corticosteroid injections, analysis demonstrated longer term benefits with HA than corticosteroid injections. The authors noted that the clinical effects of the HA products have considerable heterogeneity and therapeutic variability. However, conclusions about the clinical effectiveness of products could not be drawn given the limited data comparing products head-to-head. (6)

In a meta-analysis of literature, Pagnano and Westrich concluded repeat courses of HA for OA of the knee were as safe and effective as a single course of HA injections. (7)  However, as noted in a 2005 Blue Cross Blue Shield Association (BCBSA) Technology Evaluation Center (TEC) Special Report, there is no rigorous controlled evidence regarding the effectiveness of repeated treatments with HA. (8)

In 2009, the BCBSA TEC Evidence-based Practice Center published a technology assessment for the Agency for Healthcare Research and Quality (AHRQ) on the treatment of primary and secondary osteoarthritis of the knee.  

The report concluded that:

  • Results from 42 trials (n = 5,843) generally show positive effects of viscosupplementation on pain and function scores compared to placebo for patients with primary OA of the knee. However, the evidence on viscosupplementation is accompanied by considerable uncertainty due to variable trial quality, potential publication bias, and unclear clinical significance of the changes reported.
  • Trials of hylan G-F 20, the highest molecular weight cross-linked product, generally reported better results than other trials.
  • There was no evidence for differential effects according to subgroups defined by age, sex, primary diagnosis or disease, body mass index or weight, or disease severity.
  • Minor adverse events accompanying IA injections are common, but the relative risk accompanying hyaluronan injections over placebo appears to be small. The risk of local adverse events appears to increase with prior courses of treatment. Pseudoseptic reactions associated with hyaluronan appear relatively uncommon but can be severe. (9)

Guidelines published by the National Institute for Health and Clinical Excellence (NICE) do not recommend IA-HA injections for the treatment of OA because “the cost-effectiveness estimate is outside the realms of affordability” to the National Health Service. However, guideline developers state, “Overall, the evidence suggests that hyaluronan and hylan derivatives seem to be superior to placebo in terms of efficacy and quality of life outcomes in patients with OA in the knee at different post-injection periods but especially at the 5- to 13-week post-injection period.” Toxicity of IA-HA was noted to be small. The NICE summarizes those interventions that should be considered for patients with OA, given the patient’s individual needs, risks, and preferences. The core of patient education, strengthening exercises, and weight loss, if applicable may be the first approach in treating OA. The next tier is topical NSAIDS. Beyond those recommendations are adjunctive treatments, such as supports and braces, localized heat and cold applications, oral NSAIDS and other pain medications, and IA corticosteroid injections. (10)

In contrast, several studies investigated IA viscosupplementation for osteoarthritis (OA) of the hip (11-17). A systematic review of two RCTs and nine cohort studies concluded that viscosupplementation therapy with HA appears to be “a safe and effective method in the treatment of hip OA resistant to conventional treatment modalities.” However, the authors recommend future studies with a large number of patients to confirm results and to answer questions about doses, intervals between doses, and the number of injections needed to achieve a therapeutic and safe effect.

Several small RCTs and observational studies have investigated the use of IA viscosupplementation for OA of the ankle (18, 19), wrist (20), shoulder (21), and temporomandibular joint (22, 23). An industry-sponsored RCT of 660 patients with persistent shoulder pain due to glenohumeral joint OA, rotator cuff tear, and/or adhesive capsulitis compared three weekly injections versus five weekly injections of SH versus five weekly injections of saline. About 60% of patients had OA, although the majority of those with OA also had rotator cuff disorders or capsulitis. Sixty-nine percent (n=456) of the patients had a follow-up visit at 26 weeks. There was no significant difference among groups in the primary outcome measure, shoulder pain with movement at 13 weeks. Analysis of predefined, stratified subgroups revealed no significant differences in reported pain at 13 weeks, but a significant decrease in reported pain in both treatment groups at 26 weeks compared to placebo among patients with OA. In those without OA, there was no significant improvement with either regimen. Of note, this appears to be an as-treated analysis of the OA subgroup data. Differences in range of motion among groups were judged to be not clinically important.

2013 Update

In 2011, therapeutic trajectory following IA HA injection in KOA was studied by Bannura et al. This meta-analysis followed 7545 participants with 54 eligible trials that evaluated IA HA verses placebo with individuals diagnosed with KOA. The effect size favored IA HA by week 4 (0.31; 95%Cl0.17, 0.45), reaching peak at week 8 (0.46; 0.28, 0.65), then trending downward, with a residual detectable effect at week 24 (0.21; 0.10, 0.31). This therapeutic trajectory was consistent among a subset of high quality trials and on multivariant analysis adjusting for correlation between time points. The study concluded IA HA is efficacious by week 4 and peaks at week 8, and exerts residual detectable results at 24 weeks. (24)

In 2011, Wang et al. evaluated the effects of Hylan G-F 20 supplementation on cartilage preservation detected by magnetic resonance imaging (MRI) in KOA. This was a prospective, parallel, single blind clinical trial. Seventy eight patients with symptomatic osteoarthritis (OA) (Kellgren-Lawrence grade 11-111) were assigned to either intervention group (n=39 receiving 4 courses of 3 x2.0 ml of IA Hylan g-f 20injections in 6 month intervals) or control group (n=39 receiving usual care of KOA without injections). MRI at baseline was completed along with evaluation at 12 months and 24 months to access overall cartilage volume and defects. Fifty Five subjects (71%) completed the final 24 month followup. Over 24 months, the intervention group had a reduced annual percentage rate of medial and lateral tibial cartilage volume loss compared with the control group. The intervention group showed reduced cartilage defect score increment in the medial tibiofemoral compartment. This study concluded that monthly IA injections of Hylan G-F 20 administered to symptomatic patients with OA has a beneficial effect on knee cartilage preservation thus warranting larger, clinical trials as a possible disease modifying agent in the treatment of KOA. (25)

In 2012, Swiechowicz et al. evaluated IA HA injections in the treatment of primary and secondary OA of the knee. They followed a total of 113 patients (60 patients with primary OA and 53 patients with secondary OA), who were administered IA injections of HA into the affected knee. Concentration of lipid hydroperoxides in the blood plasma was obtained, along with malondialdehyde in erythrocytes. The comparable clinical improvement was observed in both forms of osteoarthritis of the knee. There were beneficial changes in blood antioxidants especially in the group with secondary arthritis. (26)

In 2012, Strand et al. compared a single IA injection of Gel-200, a new cross linked formulation of HA to phosphate buffered saline for treatment of KOA. The aim was to evaluate the safety and efficacy of a single IA injection. This was a multicenter, randomized, controlled trial in patients that exhibited symptomatic KOA. Patients received one IA injection. Physical function (after knee aspiration), Visual Analog Scale (VAS), and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain scores were completed. Patient safety in 377 patients and efficacy in 375 patients were evaluated. Effectiveness of Gel-200 by WOMAC pain subscores was statistically significant at week 13. Mean improvements from baseline in WOMAC pain subscores consistently favored Gel-200 at each visit. Effectiveness of Gel-200 treatment was statistically significant over week 3 - 13 based on WOMAC total score, physical function, and physician global evaluations. Adverse events were not significantly different between treatment groups, including serious adverse events considered related to study treatment. The trial demonstrated that a single injection of Gel 200 was well tolerated and relieved pain associated with symptomatic KOA over 13 weeks. (27)

In 2013, Birnbaum et al. performed a random, multicenter (50 Orthopedist and Rheumatology practice sites), double blinded, and controlled trial comparing two IA HA preparations differing by their molecular weight in individuals with symptomatic KOA. The study was designed to compare the effects of the low molecular weight (MW) HA against a well characterized intermediate MW preparation and evaluate the safety and effects of KOA. Patients were randomly selected to receive either GO-ON (MW 800-1500KD/2.5 ml) or Hylagan (500-730 KD/20 mg/2 ml) at 3 week intervals. The study consisted of 217 patients in the Hylagen group and 209 patients in the GO ON and hylan groups. The participants were treated with 3 weekly injections of intermediate MW HA. Pain scores decreased from 5.2 to 4.5 favoring Go- On, which is the higher MW product. The study determined that intermediate MW HA injections may be superior to low MW HA on KOA symptoms lasting longer than 6 months, with similar safety. (28)

In 2013, Ostalowska et al. assessed knee function and biochemical parameters of articular fluid and peripheral blood in gonarthrosis patients following IA administration of HA. The development of gonarthrosis (GA) involves inflammatory processes. The objective of the study was to examine whether IA administration of a HA agent has any effect on the function of the knee and on the selected biochemical parameters of the articular fluid and blood in GA, as well as to demonstrate of correlation or no correlation between the effects of viscosupplementation and administration of HA into a knee containing articular fluid or a "dry" knee. The study followed 22 gonarthrosis patients who received knee HA containing articular fluid and 27 GA patients who received HA into the dry knee. HA was administered IA upon the first 3 visits held in 1 week intervals, as well as on visit 4 (12 weeks after visit 3). The study knee was assessed clinically at all visits using the OA Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), visual assessment scale (VAS from 0-10) for the assessment of pain intensity and HHS questionnaire for clinical assessment of the knee function. Blood for study-related analyses was collected at initiation of the study and 12 weeks after administration of the third dose of HA. The activity of superoxide dismutase (SOD) within the articular fluid and plasma and plasma levels of MDA was determined. The study lasted 40 weeks and involved 10 visits to the study site. Inferior WOMAC scale and quality of life was observed in patients with OA and "dry" knee, mostly due to higher joint stiffness. Following viscosupplementation treatment, improvement in all tested WOMAC scores was observed in both groups. The superoxide dismutase (SOD) and the malondialdehyde (MDA) levels in plasma did not differ between the study groups, both before the study and after viscosupplementation. No statistically significant changes were observed in the biochemical parameters following viscosupplementation in both groups other than for reduced articular fluid MDA levels in the PS group. The study determined that viscosupplementation with HA administration is an effective method of conservative treatment in patients with GA. Its beneficial effect consists of mostly pain reduction and knee function improvement both in patients with articular fluid present within the knee and patients with dry knee joints. (29)

Society Guidelines

In 2008, Osteoarthritis Research Society International (OARSI) published Guidelines for the Management of Hip and Knee Osteoarthritis. OARSI guidelines state that IA HA injections may be useful in patients with knee or hip OA but the injections are characterized by delayed onset, but prolonged duration of symptomatic benefit when compared to IA injections of corticosteroids. (30)

The American College of Rheumatology (ACR) (2012) recommends the use of pharmacologic therapy with idiopathic KOA in their clinical practice guideline. Treatment modalities should include Tylenol, oral/topical NSAIDS, Tramadol, and IA steroids for the initial management of osteoarthritis of the knee. Intra-articular HA injections are approved in those individuals who fail conservative treatment. (31)

In May 2013, the American Academy of Orthopedic Surgeon (AAOS) published the Knee Osteoarthritis Clinical Guideline; it does not recommend the use of IA HA agents. The guideline concluded, although a few individual studies have found significant effects, the evidence did not meet their minimum threshold for clinical improvement when combined together in a meta-analysis. In May 2013, the AAOS indicated “It is important to clearly state that this CPG (Clinical Practice Guideline) is not intended as a tool for coverage determinations. Misinterpretation of the goals and position of the CPG process can result in confusion of the message to patients, clinicians, and payers with resultant deleterious effects.” (32)  

Summary

Based on current research data there are no additional studies that prompt a change to the current coverage position of this policy. Additional publications were added to support the current coverage position. In conclusion, HA does have some beneficial effects, although the magnitude and clinical significance of the effects may be small. Further research would be useful, such as head-to-head comparisons of the various HA products, in longer term trials and trials examining repeated courses of treatment with HA. The evidence is insufficient to determine the efficacy of hyaluronan in joints other than the knee.
