Revision Hip Arthroplasty for Ceramic-on-Ceramic Squeaking Hips Does Not Compromise the Results
Section snippets
Method and Materials
All THA patients are prospectively observed at our institution (1999-2008). From this database, a case series was obtained by grouping every THA patient who underwent revision THA surgery for squeaking after obtaining institutional ethics review board approval. Inclusion criteria were revision for squeaking if the index THA was done at our institution and a minimum 1 year follow-up. Patients were excluded if there was a concomitant reason for the revision such as component loosening or if the
Results
All patients reported squeaking on average 14 months (range, 5-20 months) after the index THA. The activities that caused the squeaking varied among the patients, whereas most patients complained about squeaking when walking (8 hips), bending forward (5 hips), standing from a seated position (3 hips), or going up/down stairs (3 hips). Two patients (2 hips) complained of mild to moderate intermittent pain in the groin area, but most of squeaking hips were not painful. In all patients, the
Discussion
The etiology of squeaking post CoC THA is believed to be multifactorial involving patient, surgical, and implant factors 1, 2, 5, 8. Walter et al [1] previously reported that squeaking is associated with an increased acetabular component anteversion. However, we recently published a study that failed to corroborate these findings when no difference was found in a group of squeaking hips and a matched group of nonsqueaking hips with regard to acetabular inclination and version [2]. The measured
Conclusion
In the CoC squeaking hip that can no longer be tolerated by the patient, head-and-liner exchange to a metal-on-highly cross-linked polyethylene is an effective method to eliminate squeaking. The use of larger femoral heads, through the direct lateral approach, results in low dislocation rates and low morbidity rendering the procedure relatively benign with low morbidity.
