Assessment of Cup Placement Impact on Functional Outcomes in Total Hip Replacement: A Retrospective Analysis of 20 Patients

Introduction:Total hip replacement surgery is gaining popularity as a treatment for hip disorders, replacing alternative treatments like excisional arthroplasty, osteotomy, arthrodesis, and hemiarthroplasty. This research aims to evaluate the effect of the acetabular cup on functional outcomes, particularly in younger patients with hip arthritis and femur neck fractures.Materials And Methods:This study aimed to evaluate the placement of the acetabular cup and its association with functional outcomes in total hip replacement (THR). 20 patients were randomly selected from the MRD department and underwent pelvic CT scans postoperatively. Functional results have been analyzed using the Harris Hip Score. The acceptable cup version range was 15 ± 10 degrees, and patients outside this range were closely examined for rotational movements. Results: A study of 20 patients with a neck or femur fracture found that 11 patients had a right knee injury, while 9 had a left knee injury. After a year postoperatively, 18 patients reported no pain, while 2 had mild pain. Functional assessment depicted better outcomes in 17 patients, good outcomes in 2 patients, and fair outcomes in 1 patient. Radiological analysis revealed a mean cup version of 17.77 degrees, with complications including one dislocation and three limb length discrepancies. None of the patients developed an infection.Conclusion:The study found that 90% of patients had excellent functional outcomes, with only 10% exhibiting excessive anteversion. CT scan-based measurements of cup placement provided reliable predictions, consistent with intraoperative assessment of cup positioning.
