NCT05157464

Brief 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.

Outcome Measures

Primary Outcomes (2)

  • Post-Operative Range of Motion (ROM)

    ROM will be reported as the degree of knee flexion.

    90 days post-surgery

  • Post-Operative Rate of Manipulation under Anesthesia (MUA)

    Rate of MUA will be reported as percentage of participants that require MUA.

    90 days post-surgery

Study Arms (2)

Losartan Group

EXPERIMENTAL
Drug: Losartan

Control Group

NO INTERVENTION

No additional steps in management are required for the control arm of the study.

Interventions

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.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients are candidates for elective primary total knee arthroplasty for a diagnosis of osteoarthritis or inflammatory arthritis.
  • Patients ≥18 years of age
  • Patients have been medically cleared and scheduled for surgery
  • Patients' primary care physician has verified that the patient can safely take the described dose of Losartan for the duration of the study period.

You may not qualify if:

  • Any contraindications to Losartan
  • Revision surgery
  • Surgery for fracture, infection, or malignancy
  • Patients with a diagnosis of post-traumatic arthritis
  • Bilateral, simultaneous surgery
  • Patients already taking an ACE-inhibitor or Angiotensin receptor blocker for hypertension
