Squeaking in Ceramic-on-Ceramic Total Hip Arthroplasty Using Delta TT Cup

Squeaking in Ceramic-on-Ceramic Total Hip Arthroplasty Using Delta TT Cup

This study will evaluate clinical outcome on patients who undergo ceramic on ceramic (CoC) bearing total hip arthroplasty (THA) using Delta TT cup.

This study will evaluate clinical outcome on patients who undergo ceramic on ceramic (CoC) bearing total hip arthroplasty (THA) using Delta TT cup. Specifically the study intends to address the following research topics:

1. The incidence of squeaking after CoC THA using Delta TT cup.
2. The dislocation rate and survival rate of CoC THA using Delta TT cup.
