Abstract:

BACKGROUND: Ceramic joint has been used in the clinic due to its excellent wear resistance, high hardness and good biocompatibility. But the comparative studies at home and abroad on ceramics-on-ceramic and traditional metal-on-polyethylene total hip arthroplasty are rare.
OBJECTIVE: To retrospectively observe the therapeutic effects of ceramics-on-ceramic and traditional metal-on-polyethylene total hip prosthesis replacement for the treatment of adult hip disease.
METHODS: In the period of October 2007–September 2010, a total of 42 patients (44 hips) received total hip arthroplasty, and 20 patients (22 hips) received ceramics-on-ceramic total hip prosthesis replacement, 22 patients (22 hips) received traditional metal-on-polyethylene total hip prosthesis replacement. All the surgical methods were the standard posterolateral approach, then given the routine postoperative anticoagulation treatment and the corresponding functional exercise. Regular postoperative clinical and radiographic follow-up was performed for at least six months. Range of motion was measured both before replacement and 6 months after replacement, and the hip joint function was evaluated according to Harris score.
RESULTS AND CONCLUSION: The clinical effects of all patients were good without dislocation, loosening, infection, deep venous thrombosis and other complications. The Harris scores and the range of motion of ceramics-on-ceramic group was significantly improved (P < 0.05). There was no significant difference of Harris scores and the range of motion between ceramics-on-ceramic group and traditional metal-on-polyethylene group (P > 0.05). The effect of ceramic-on-ceramic prosthesis is good and the results are satisfactory for short-term follow-up. There is no difference of improving symptoms and hip range of motion between ceramics-on-ceramic and metal-on-polyethylene total hip prosthesis. However, its advantages and the long-term efficacy remain to be further observed. Because of the wear resisting, ceramics-on-ceramic total hip prosthesis will be a good choice for the young patients undergoing hip replacement surgery.
