Extra-articular Stabilization of Cranial Cruciate Ligament-deficient Stifle in Dogs: a New Tibial Suture Anchor Point

We described a new surgical procedure of extra-articular stabilization of cranial cruciate ligament (CCL) deficient stifle using nylon cable tie (NCT) anchored in a new tibial anchor point. Lateral fabellotibial tension band (LFTB) stabilization procedure was described in 10 mixed breed dogs. The degree of lameness was scored and complete physical examination of each dog was performed. Radiographic assessment of stifle osteoarthritis and postoperative complications were recorded. Mechanical properties of the NCT were determined. Clinical lameness was improved by 6 weeks postoperatively in all dogs. No joint laxity or abnormal range of motion was detected during the first 4 weeks after surgery. Minimal cranial drawer motion was apparent in three operated limbs 6 weeks postoperatively with no apparent lameness. No clinical lameness was observed 12 weeks postoperatively. Minimal progression of stifle osteoarthritis was observed in one dog. Implant loosening was the only major postoperative complication. Lateral fabellotibial tension band procedure is a simple and effective method of stabilization of CCL-deficient stifle with good to excellent clinical outcome and minimal stifle osteoarthritis. Longer-term evaluation of stifle osteoarthritis is however needed. Nylon cable tie (NCT) may be an appropriate inexpensive alternative to the traditional lateral fabellotibial suture material.
