Tibial Plateau Leveling and Medial Opening Crescentic Osteotomy for Treatment of Cranial Cruciate Ligament Rupture in Dogs with Tibia Vara
Objective
To report clinical application of a tibial plateau leveling and medial opening crescentic osteotomy (TPLMOCO) by a single blade cut to ameliorate lameness in dogs with cranial cruciate ligament (CCL) rupture (CCLR) and concur- rent tibia vara.
Methods
Dogs were evaluated clinically and radiographically and records retro- spectively reviewed. Pins were driven through both cortices of the proximal and distal tibia and a multidirectional jig attached medially. Tibial plateau leveling osteotomy was performed with torsional realignment of the calcaneo-patellar axis. A rigid connecting bar applied to the pins laterally before distraction of the medial jig allowed medial opening of the osteotomy while maintaining contact on the lat- eral aspect of the osteotomy. A 3.5 mm plate was applied.
Results
Meniscal and articular cartilage pathology was identified in the medial joint compartment in 4 stifles, and in both medial and lateral compartments in 1 stifle. Postoperatively, subjectively assessed lameness resolved in 4/5 limbs and improved in 1 limb. All osteotomies healed uneventfully, with superficial wound infection being the only complication in 1 dog.
Clinical relevance
TPLMOCO offers a potential treatment option and warrants further investigation for use in selected cases.
