Patient Satisfaction After Robotic-Assisted Versus Conventional Total Knee Arthroplasty

Total knee arthroplasty (TKA) remains the definitive treatment for advanced knee osteoarthritis and continues to be performed with increasing frequency worldwide. However, patient dissatisfaction remains reported in up to one-fifth of cases, despite technically successful procedures and acceptable radiographic results. This discrepancy has shifted attention toward early functional recovery and patient-reported outcomes as more meaningful indicators of success. In response, technological innovations such as robotic-assisted total knee arthroplasty have been introduced to enhance surgical precision and reduce alignment outliers. This study aims to determine whether these technical advantages translate into improved early clinical outcomes by comparing patient satisfaction, functional results, radiological accuracy, and perioperative parameters between robotic-assisted and conventional total knee arthroplasty over one year.

Inclusion Criteria: * Patients with symptomatic end-stage primary knee osteoarthritis. Exclusion Criteria: * Body mass index (BMI) (\> 40 kg/m²) * Significant coronal deformity (\>20° varus deformity and \>15° valgus deformity) * Significant flexion deformity (\>15° flexion deformity) * Previous major knee surgery (high tibial osteotomies (HTO) , osteosynthesis) excluding surgeries not affecting joint line e.g.: knee arthroscopies (meniscal repair) * Secondary OA (post traumatic or post infectious) * Significant osteoporosis or bone loss ▪ Musculoskeletal disease impairing gait/function e.g., spine or hip disabling disorders * Extra-articular lower limb deformities necessitating additional surgical intervention * American Society of Anesthesiologists (ASA) score more than stage 3 * Poorly controlled Diabetic and hypertensive patients. ▪ Septic focus necessitating eradication e.g., dental caries, chest infection, diabetic foot.
