Stifle Anchor Pro

Stifle Anchor Pro is the anchoring backbone of the Hongyu sports-medicine line. It addresses cranial cruciate ligament rupture, the single most common orthopedic presentation in canine practice, with implants and instrumentation specified around canine stifle loads instead of repurposed human shoulder hardware. Each tray contains anchors, a matched drill, an aiming guide, and pre-loaded suture, so tunnel preparation and fixation happen without switching kits mid-procedure.

Two anchor materials are offered on the same geometry. PEEK anchors are the default for revision cases and larger patients where long-term radiographic visibility and permanent fixation are preferred. Bioabsorbable composite anchors suit primary repair in smaller patients, resorbing over a 6 to 12 month window that tracks the expected remodeling timeline of the reconstructed ligament.

Features

• Load-matched fixation. Pull-out strength of 320 N or greater is specified against measured canine CCL loading, not extrapolated from human data.
• Dual material options. PEEK and bioabsorbable composite anchors share one geometry and one instrument set.
• Integrated aiming guide. The guide fixes tunnel entry and exit points to keep the graft path reproducible between surgeons.
• Pre-loaded UHMWPE suture. High-tenacity suture arrives seated in the anchor, removing a threading step at the table.

Indications

• Cranial cruciate ligament rupture, primary extracapsular and arthroscopic-assisted reconstruction
• CCL revision surgery following failed primary repair
• Collateral ligament reconstruction in the stifle and tarsus
• Soft-tissue reattachment where bone anchoring is required
