Background Although hip arthroplasty has become increasingly common, its radiological and clinical outcomes in chronic renal failure patients remain unclear. This study analyzed the outcomes of hip arthroplasty in patients with chronic renal failure undergoing dialysis. Methods Of 2,364 hips undergoing total hip arthroplasty or bipolar hemiarthroplasty between January 2003 and December 2017, data pertaining of 37 hips of patients with chronic renal failure undergoing dialysis (16 men, 21 women) were retrospectively examined. We analyzed the radiological and clinical outcomes of hip arthroplasty, as well as the occurrence of local and general complications (particularly the time of their occurrence) during follow-up and their association with dialysis duration. Results The mean patient age was 60.6 ± 13.5 years, and the mean follow-up duration was 36.6 ± 27.2 months. The mean T-value indicating bone mineral density was -2.62 ± 1.15, with osteoporosis noted in 20 cases. Except for 1 case with infection-induced change in acetabular cup tilt, all cases of total hip arthroplasty with cementless acetabular cup implant exhibited excellent radiographic outcomes. The cementless proximally coated femoral stem was used in all 25 cases of total hip arthroplasty and 7 out of 12 cases of bipolar hemiarthroplasty. Changes in the alignment of femoral stems, subsidence, osteolysis, and loosening were not observed. On clinical assessment, 33 patients received an “excellent” or “good” Harris hip score. Within 1 year postoperatively, complications developed in 18 patients, and some patients exhibited more than 1 complication. More than 1 year after surgery, general complications developed in 12 patients; however, no patient experienced local complications.Conclusions Hip arthroplasty in chronic renal failure patients on dialysis showed excellent radiological and satisfactory clinical outcomes; however, it may be associated with various postoperative complications. Therefore, meticulous preoperative treatment planning and overall postoperative management are required to reduce the risk of complications. |
