Metal Ion Concentrations After Total Knee Arthroplasty

Analysis of Metal Ion Concentrations After Robotic-assisted Total Knee Arthroplasty Compared to Conventional Total Knee Arthroplasty

The purpose of this study is to analyze the metal ion concentrations in the patients blood following robotic-assisted total knee arthroplasty (TKA) compared to conventional total knee arthroplasty using cutting guides.

This study focuses on comparing metal ion levels in 50 inpatient participants undergoing primary total knee arthroplasty (TKA) with either conventional cutting guides or robotic assistance. Baseline blood examinations for Cobalt, Chromium, Titanium, and Nickel will be performed before TKA implantation at preoperative visits and on the first day following the procedure. The investigation will encompass patients receiving both conventional and robotic-assisted primary TKA, framed within a prospective cohort study design. Baseline characteristics and additional follow-up information will be gathered.

Inclusion Criteria:

• Adults undergoing conventional or robotic-assisted TKA
• Consent to the study

Exclusion Criteria:

• Patients who have undergone any previous arthroplasty procedures.
• Patients with metal implants, such as plates, nails, and screws, used in the repair of traumatic injuries.
• Patients below 110 pounds.
