The Claim

Corticosteroid injections are more effective than physiotherapy or rehabilitation in treating chronic tendon injuries.

Verified by Lenz ·

The Short Version

This claim is not supported by the evidence. Multiple systematic reviews and meta-analyses consistently show that corticosteroid injections provide only short-term pain relief (weeks) for tendon injuries, while physiotherapy produces equal or superior outcomes at 3–12+ months. For chronic tendon injuries specifically, a PMC-NIH review found "no good evidence" supporting corticosteroid use, and a 2025 PubMed meta-analysis confirmed injections are not superior to physical therapy beyond the short term. Clinical guidelines treat injections as adjuncts to rehabilitation, not replacements.

Caveats

  • Corticosteroid injections show short-term pain relief only (weeks); this benefit reverses at intermediate and long-term follow-up, where physiotherapy is equal or superior across multiple systematic reviews.
  • Corticosteroid injections carry significant safety risks for tendons, including inhibition of healing and increased rupture risk, which are directly relevant to any effectiveness comparison for chronic conditions.
  • Clinical guidelines from AAFP and Mayo Clinic position corticosteroid injections as temporary analgesic adjuncts to initiate physiotherapy — not as standalone treatments superior to rehabilitation.
