Timing of Monovisc After Steroid Injection in the Knee
There is no required waiting period between a corticosteroid injection and subsequent Monovisc (hyaluronic acid) injection in the knee, and you can proceed with viscosupplementation immediately if clinically indicated. 1
Evidence-Based Timing Recommendations
No Mandatory Interval Required
Current clinical guidelines do not specify any required waiting period between corticosteroid injections and viscosupplementation when transitioning between these treatments for knee osteoarthritis. 1
The VA/DoD and EULAR guidelines discuss both treatment modalities as management options without establishing any mandatory interval between them. 1
This lack of restriction applies specifically when moving from corticosteroid to hyaluronic acid injections (the reverse sequence from your question). 1
Clinical Considerations for Sequencing
While no formal waiting period exists, consider these practical factors:
Assess the response to the steroid injection first before proceeding with viscosupplementation, as corticosteroids typically provide relief within 1-2 weeks. 2
If the steroid injection provided inadequate or short-lived relief, Monovisc can be administered without delay as an alternative therapeutic approach. 3
Monovisc demonstrates effectiveness within 2 weeks of injection and maintains benefit through 26 weeks in clinical trials. 3
Important Safety Caveats
Avoid both corticosteroid and hyaluronic acid injections within 3 months before planned total knee arthroplasty due to significantly increased infection risk:
Corticosteroid injections within 3 months pre-operatively increase periprosthetic joint infection risk (OR 1.39, p=0.03). 4
Hyaluronic acid injections within 3 months pre-operatively similarly increase infection risk (OR 1.55, p=0.029). 5
No increased infection risk exists when either injection type is given >3 months before surgery. 5
Limit total corticosteroid injections to 3-4 per year maximum in the same joint to prevent accelerated cartilage loss and avoid increasing the likelihood of requiring arthroplasty. 1
Special Population Considerations
Diabetic patients require glucose monitoring for 1-3 days following corticosteroid injections due to transient hyperglycemia risk, particularly in those with suboptimal glycemic control. 1, 6
Patients should avoid overuse of the injected joint for 24 hours post-injection but should not immobilize the knee. 6
