Condylar Offset and Outcomes in Primary Total Knee Arthroplasty

Prospective Evaluation of Posterior and Anterior Condylar Offset and Their Impact on Functional Outcomes in Primary Total Knee Arthroplasty

This prospective cohort study aims to evaluate the effect of posterior condylar offset (PCO) and anterior condylar offset (ACO) changes on functional outcomes after primary total knee arthroplasty (TKA). Standardized imaging and clinical assessment protocols will be used to determine optimal PCO and ACO ranges associated with improved postoperative range of motion, patient-reported outcomes, and reduced anterior knee symptoms.

Inclusion Criteria:

• diagnosis of primary knee osteoarthiritis
• indication of knee arthroplasty
• 50-85 years
• ability t oprovide informed consent and comply with follow up

Exclusion Criteria:

• revision knee arthroplasty
• inflammatory arthritis
• severe corona deformity (>20 varus/valgus)
• previous knee surgery or fracture
