Very Low Preoperative Grip Strength Associated With Poor Pyrocarbon Metacarpophalangeal Implant Survivorship in Rheumatoid Arthritis.

ABSTRACT:

Background

Pyrocarbon metacarpophalangeal (MCP) arthroplasty is associated with high rates of recurrent deformity and reoperation in patients with rheumatoid arthritis (RA). We sought to determine the impact of preoperative hand grip strength (HGS) on implant survivorship in these patients.

Methods

We included primary pyrocarbon MCP arthroplasties in patients with RA at our single institution from 2000 to 2022. Cox proportional hazard models with restricted cubic splines were used to model the continuous relationship between HGS and hazard for revision, all-cause reoperation, and development of any complication, accounting for multiple joints per patient and adjusting for sex. Kaplan-Meier estimates were used to report survivorship at 2, 5, and 10 years.
