Losartan Use to Mitigate Arthrofibrosis Following Total Join Arthroplasty

NCT05157464 · Status: WITHDRAWN · Phase: PHASE4 · Type: INTERVENTIONAL

Summary

Recent research has focused on methods to mitigate scar tissue formation and arthrofibrosis following surgery in hopes that patients may attain maximal range of motion goals, avoid manipulation and secondary surgery (i.e. revision arthroplasty), and improve their function. The synovial fluid milieu has also highlighted the role of local biochemical markers that may be implicated in the development of arthrofibrosis. Losartan is an angiotensin receptor blocker with inhibitory effects on transforming growth factor beta (TGF-b), largely implicated in tissue repair and fibrosis by way of SMAD protein signaling suppression, and has been used in orthopaedic sports medicine to prevent stiffness following hip arthroscopy. To date, this has not commonly been used at NYU Langone in orthopedic surgery. The purpose of this study is to evaluate the efficacy of losartan use pre- and post-operatively on range of motion and the incidence of manipulation under anesthesia following total knee arthroplasty.

Conditions

  • Arthrofibrosis

Interventions

DRUG

Losartan

Patients in this group will receive Losartan 12.5mg orally twice daily beginning 2 weeks preoperatively and continuing for 4 weeks postoperatively. Losartan is an Angiotensin II Receptor Blocker currently used in the treatment of hypertension.
