Background
The most common articulation used in total hip arthroplasty is metal on polyethylene.
However, nowadays, with young and more active patients undergoing the procedure,
other bearing surfaces such as metal on metal and ceramic on ceramic have been
proposed as an alternative to metal on polyethylene as a solution to the need for
reducing wears debris production with subsequent osteolysis and loosening.
Aim of the work
The aim of this study is to evaluate the early outcome of total hip replacement using the
ceramic-on-ceramic articulations.
Patients and methods
This prospective study included 13 patients (15 hips) who had end-stage arthritic hips.
All patients were subjected to clinical, laboratory, and radiological evaluation before
surgery and up to 3 years postoperatively.
Results
There was a marked improvement in the Harris Hip Score (satisfactory results in
93.3% of the studied group at the last follow-up) especially in the range of motion of
the hip joint and postoperative pain relief.
Conclusion
The results were very satisfactory and significantly in favor of using this bearing
combination, taking advantage of both the hard, wear-resistant ceramic material and
the cementless acetabular fixation. This choice also broadens the spectrum of
candidates for total hip replacement including young active women of child-bearing
age and men with renal impairment or any patient with less accepted bone quality. |
