What this trial studies

This observational study aims to evaluate the functional and patient-reported outcomes of individuals undergoing total wrist replacement using the KinematX total wrist arthroplasty system. Participants will be monitored for a range of motion, grip and pinch strength, and various patient-reported outcomes at multiple time points, including 3, 6, and 12 months post-surgery, and annually for up to 10 years. The study will collect preoperative and postoperative data to assess changes over time and determine the effectiveness of the KinematX implant in improving wrist function.

Who should consider this trial

Good fit: Ideal candidates include adults with specific wrist conditions such as SLAC, SCAC, STTAC, carpal tunnel syndrome, or Kienbock's disease who are undergoing total wrist arthroplasty with the KinematX implant.

Not a fit: Patients under 18 or over 85 years of age, as well as those with certain contraindications or severe wrist conditions, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the long-term effectiveness and patient satisfaction associated with total wrist replacement, potentially improving treatment options for patients with wrist conditions.

How similar studies have performed: While this study focuses on a specific implant, similar observational studies on total wrist arthroplasty have shown promising outcomes, suggesting that this approach may yield beneficial results.
