Long-Term results of total Hip Arthroplasty performed using a cementless expansive Acetabular Cup and Spotorno Femoral Stem

Abstract

Objective: In this study we aimed to investigate the long-term clinical and radiological results, revision rates and causes, and the rate of implant survival in total hip arthroplasty performed using CLS® expansion cup and Spotorno® cementless femoral stem.
 Methods: Clinical results of total hip arthroplasty performed on 131 hips of 114 patients in Istanbul Training and Research Hospital between 1993 and 2003 were retrospectively evaluated according to the Harris Hip Score. Revision rates were determined and implant survival rates were identified using the Kaplan-Meier estimator.
 Results: Of the patients, 39 were males and 75 were females. The average age of the patients at surgery was 48.7±11.3 years. Patients were followed up for a mean period of 13.9±2.4 years. The mean Harris Hip Score was 34.35±6.09 preoperatively and 88.20±7.11 at the final follow-up (p<0.001). The Kaplan-Meier survivorship estimate for the cup at 13.9 years, taking revision for any reason as the end point was 95.6% (95% CI), while the 15th and 17th year survival rates were 90% and 85%, respectively.
 Conclusion: In total hip arthroplasty using a cementless expansive acetabular cup, a 95.6% survival rate is achieved after an average of 14 years, whereas the rate decreases to 85% after 17 years. Even if the incidence of cup breakage is reduced with proper implantation, particle disease and periacetabular osteolysis remains a problem for the long-term survival.

Correlation analysis of Blood TM, TG and D-dimer with deep venous Thrombosis formation in patients after Total Hip Arthroplasty

“…THA has been considered to be the primary surgery for joint replacement, and the complications caused by THA have been concerned by both the departments of medicine and surgery. 9 , 10 DVT is a common postoperative complication that occurs frequently in the lower limbs, which has common clinical manifestations of limb swelling, pain, skin damage and ulceration, etc. In the absence of timely intervention, it may induce pulmonary embolism and affect the postoperative quality of life.…”
