Impact of Post-operative Radiological Parameters on Total Knee Arthroplasty Functional Outcome

BACKGROUND: Total knee arthroplasty (TKA) is effective in treating end-stage osteoarthritis. Nevertheless, 20% of patients remain unsatisfied with the outcome at 1 year. AIM: The aim our study was to identify radiological parameters influencing functional result and patient’s quality life (QOL). METHODS: We conducted a retrospective observational who underwent primary TKA between 2015 2019. Standard radiographs were used assess alignment parameters, patellar height, implant size. Knee function assessed using Society Score (KSS) QOL through “Sfax modified Western Ontario McMaster Universities osteoarthritis index (WOMAC).” RESULTS: One hundred twenty cases analyzed. results terms showed on average: an overall 2.41° varus, coronal orientation femoral component 5.49° valgus, tibial 2.16° flexion 0.7°, slope 2.6° posterior orientation. identified 19 Patella baja (PB) seven pseudo PB. 18 oversizing six undersizing. oversized ten undersized three cases. Global limb significantly influenced KSS WOMAC scores. There also significant association function, QOL. Femoral size overhang influence only score. CONCLUSION: radiography can be reliable evaluate TKAs. According results, we may suggest checklist aiming optimize It should include mechanical limb, component, prevention iatrogenic tendon shortening, precision choice.
