Outcomes of 11 cats with Achilles tendon (AT) rupture repair treated with a synthetic ultra-high-molecular-weight polyethylene (UHMWPE)
🔍 Key Findings
- UHMWPE implant reconstruction resulted in successful long-term functional recovery in 11/12 limbs (91.7%) with complete follow-up, with restoration of normal tarsal motion in most cats.
- All injuries occurred at the tendino-osseous junction, with 53.8% being complete Achilles tendon ruptures and 46.2% partial gastrocnemius avulsions (Type IIc).
- No intraoperative complications occurred in any of the 13 repaired limbs.
- Complication rate was low (15.4%), with only one calcaneal fracture from screw malposition and one surgical site infection causing implant failure.
- External coaptation was not required in all cases, and outcomes did not differ between limbs with or without rigid coaptation.
- Median long-term follow-up was 18.5 months, with a median FMPI score of 1.5 indicating excellent owner-reported limb function.
- Calcaneal fracture risk was associated with distal interference screw malposition, emphasizing the importance of correct screw placement proximal and caudal to the talocalcaneal central joint.
- The technique may reduce complications associated with transarticular fixation or external skeletal fixation, potentially improving short-term recovery while preserving tendon loading during healing.
