What is the evidence for injections (corticosteroid, viscosupplementation, PRP) for arthritis of the ankle?
Summary
Patient Population:
27 studies with 1085 patients with ankle OA, rheumatoid arthritis (RA) and hemophilic arthropathy.
7 studies were RCT’s.
Incomplete data on male to female ratio
Intervention:
Injection with corticosteroids (triamcinolone, betamethasone) (4 case studies), hyaluronic acid (viscosupplementation) (19 trials), platelet-rich plasma (PRP) (3 studies) and mesenchymal stem cells (1 study)
Comparison:
7 RCT’s controls (saline injection (3), botulinum toxin, traction device, exercise therapy and variable dosing)
Outcome:
Corticosteroid injection (4 case studies)
- Low quality evidence of short term (4 weeks) benefit for pain reduction
Hyaluronic Acid (19 studies)
- Pool data from 3 RCT’s with saline injection controls
- No statistical benefit for Ankle Osteoarthritis Scale (AOS) at 6 weeks, nor 3 months
- Statistical benefit in favour of HA at 6 months v. Saline injection
Platelet-rich Plasma (PRP) (3 studies)
- Low quality mixed evidence of efficacy (1 negative, 2 positive)
- Safety demonstrated in 2 trials
Mesenchymal Stem Cells (1 case series)
- Low quality evidence in single small (6 patients) 30 month trial of benefit
