🔍 Key Findings

• Coaptationless multiligament reconstruction restored stifle stability in all 23 cats, allowing immediate postoperative weight bearing without external immobilization.
• Successful outcome was achieved in 22/23 cats (95.7%), with only one case requiring arthrodesis after recurrent instability.
• Reconstruction of the caudal cruciate ligament (CdCrL) proved critical, as 3 of 4 caudal subluxation complications occurred when the CdCrL was not reconstructed initially.
• Major complications occurred in 26.6% (6/23) and consisted primarily of caudal tibial subluxation (4 cases) and medial patellar luxation (2 cases).
• Revision surgery successfully restored function in most complications, with stable joints and excellent FMPI scores after revision.
• Excellent functional outcomes were reported, with FMPI scores ranging from 0.95–1.0 at 6 months and lameness absent in nearly all cats.
• Early mobilization without postoperative immobilization preserved range of motion, with minimal osteoarthritis progression observed over 6 months.
• Internal brace principles using TightRope constructs, knotless anchors, and UHMWPE sutures provided strong multiplanar stabilization, supporting immediate limb use and favorable clinical outcomes.
