This investigation compares the outcomes of proximal interphalangeal (PIP) arthroplasty in patients older than and younger than 60 years.
Overall, 299 consecutive, primary PIP arthroplasties were performed over a 14-year period, including 126 arthroplasties performed in patients younger than 60 years. In younger patients group, a higher rate of posttraumatic and inflammatory arthritis was observed.
In patients younger than 60 years, 32 (25%) revision surgeries occurred. Risk of revision surgery was associated with younger age. The 10-year implant survival rate was 72% for the patients younger than 60 years versus 86% for those older than 60 years. Silicone implants decreased the risk of revision surgery, although it was increased in posttraumatic arthritis. The most common complication in young patients was dislocation (n = 21). At a mean follow-up of 6.4 years, pain levels had significantly improved in patients younger than 60 years, and PIP range of motion and pinch strength were maintained. However, older patients had improved PIP motion compared with younger patients.
Younger age leads higher revision rates after PIP arthroplasty, particularly in the posttraumatic setting.
