🔍 Key Findings
From “Long-term follow up of 44 cats undergoing total hip replacement” by Rodiño Tilve et al.
- Slipped capital femoral epiphysis (SCFE) was the most common surgical indication (61%, 34/56 hips), primarily affecting young neutered male cats.
- All THRs used cemented micro/nano BioMedtrix implants; most common femoral stem was size #3, and most common acetabular cup was 12 mm.
- Postoperative complication rate was 19.6% (11/56) with 9 major complications (luxation most common), and no intraoperative complications reported.
- All luxations occurred in hips implanted with femoral neck +0 mm length implants.
- Second luxations were more common when revision used same implant size; use of larger implants reduced reluxation rates.
- FMPI-sf score improved significantly from median 2.111 pre-op to 0.111 post-op (P < .001), indicating reduced pain and improved function.
- Very high owner satisfaction: 91% (30/33) reported outcome as "very good."
- No significant associations found between complications and variables like weight, sex, implant size, or surgical indication.
