Osteoarthritis

Treatment

Touch® Prosthesis

Clinical Study ID

NCT05849506
OE-0203
  • Ages > 18
  • All Genders

Study Summary

The study aims to determine whether CMC I arthroplasty using a Touch® implant results in higher patient satisfaction compared to RSI arthroplasty in the medium-term in patients with primary thumb osteoarthritis. Additionally, the study compares the patients' clinical and self-reported outcomes between the Touch® implant and the RSI arthroplasty. Therefore, patients with a Touch® implant in one thumb and an RSI arthroplasty in the other thumb will be recruited.

Eligibility Criteria

Inclusion

Inclusion Criteria:

  • Informed Consent signed by the patient.
  • Patient is diagnosed with primary OA in both CMC I joints and was operated with aTouch® prosthesis on one thumb and with an RSI arthroplasty on the other thumb.

Exclusion

Exclusion Criteria:

  • Patient with any type of revision surgery at the CMC I joint
  • Patient underwent hand surgery within the last three months
  • Legal incompetence

Study Description

Patients suffering from osteoarthritis in the first carpometacarpal joint (CMC I OA) are often surgically treated with a resection-suspension-interposition (RSI) arthroplasty. An alternative technique is an arthroplasty with a Touch® implant. There is a growing body of evidence indicating that patients with a Touch® prosthesis recover significantly faster and return to work more quickly than patients after an RSI arthroplasty. However, there have been no studies comparing the two operations in the same patient. By recruiting patients with a Touch® implant in one thumb and an RSI arthroplasty in the other thumb, this study aims to investigate whether CMC I arthroplasty using a Touch® implant leads to higher patient satisfaction compared to RSI arthroplasty in the medium-term. Further patient-reported and clinical outcomes will be assessed to compare the two surgeries.
