What this trial studies

This interventional study compares patient-reported articular noise after primary total knee arthroplasty using an ultra-congruent (Score 2, Amplitude) versus a posterior-stabilized (Anatomic, Amplitude) prosthesis. Adult patients scheduled for primary TKA at St Marguerite clinic who meet inclusion and exclusion criteria will be enrolled and receive one of the two implants during surgery. The primary outcome is patient-perceived noise (clicking, snapping, cracking, or popping) collected as a patient-reported outcome at defined postoperative time points. The trial excludes revision cases, major coronal deformities, pregnancy, and patients unable to consent or comply with study procedures.

Who should consider this trial

Good fit: Adults undergoing primary total knee arthroplasty who can give informed consent, are affiliated with a social security scheme, and meet the listed anatomical and medical inclusion criteria are ideal candidates.

Not a fit: Patients requiring revision TKA, with prior significant knee surgery on the studied knee, large coronal deformities, pregnancy, or inability to follow study procedures are unlikely to benefit from participation.

Why it matters

Potential benefit: If differences are found, surgeons could choose the implant type that reduces bothersome joint noise and potentially improve patient satisfaction after knee replacement.

How similar studies have performed: Existing literature is mixed: a large study reported an association between noise and early residual symptoms while smaller work found no link to one-year satisfaction, so the question remains unresolved.
