Veterinary Orthopedic Plates & Implants: A Complete Guide to Joint Stabilization and Fracture Repair

Introduction

Every veterinary surgeon knows the frustration: a complex orthopedic case lands on the table, and the implants available don’t quite match the precision the case needs. Human orthopedic surgeons have long benefited from purpose-built solutions for nearly every clinical scenario. Veterinary professionals, by contrast, have historically been forced to improvise.

That gap has closed dramatically over the past decade. Today’s veterinary orthopedic implant market offers purpose-engineered solutions across two major categories: joint-stabilizing plates for procedures like TPLO and patellar luxation correction, and osteosynthesis plates for fracture repair. The breadth of available systems now covers patients from 1 kg toy breeds to 60+ kg giant breeds.

This guide breaks down what modern veterinary surgeons should know about both categories. We use the LeiLOX system — distributed by VetOvation in partnership with German manufacturer Rita Leibinger Medical — as an example throughout, since it spans the full range of techniques and sizes most general orthopedic practices encounter.

Part 1: Joint Stabilization Plates

The majority of orthopedic plate systems in veterinary medicine are designed for joint stabilization — correcting biomechanical dysfunction in the stifle, patella, and surrounding structures. Five core systems cover the vast majority of joint stabilization procedures.

TPLO plates (Tibial Plateau Leveling Osteotomy)

Tibial Plateau Leveling Osteotomy remains the most widely performed procedure for cranial cruciate ligament (CrCL) rupture in dogs. It is widely considered the gold standard for cruciate repair in medium-to-large breeds, with extensive long-term outcome data supporting its use.

Modern TPLO plates have evolved significantly from earlier generations.  Anatomically precontoured shapes match the natural geometry of the proximal tibia, reducing the need for intraoperative bending. Limited-contact undersurface designs preserve periosteal blood supply. Multiaxial locking technology lets surgeons angle screws away from vital structures while maintaining angular stability.

VetOvation’s TPLO Plating Systems line includes both stainless steel and titanium variants. The LeiLox Locking TPLO Plates in Stainless Steel offer proven rigidity at a lower price point, while the LeiLox Swing Locking TPLO Plates in Titanium add superior biocompatibility and reduced imaging artifact. For practices stocking a complete TPLO setup, the Titanium LeiLOX TPLO Plating System (2.7mm/3.5mm) bundles plates, screws, and tray for medium to giant breeds.

A key efficiency feature worth noting: the 2.7/3.5 mm plates accept both 2.7 mm and 3.5 mm screws, and the same cross-compatibility exists in the 2.0/2.4 mm range. This reduces inventory cost while preserving surgical flexibility on the table. Precision osteotomy is supported by TPLO Osteotomy Guides available in multiple sizes. 

CBLO plates (CORA-Based Leveling Osteotomy)

CBLO is a more recent evolution that combines aspects of TTA and TPLO into a single technique. Like TPLO, CBLO levels the tibial plateau — but the cut is positioned over the bone’s Center of Rotation of Angulation (CORA), further distally on the tibia. Recent peer-reviewed comparisons of TPLO, CBLO, and CCWO outcomes have shaped how surgeons think about technique selection.

This positioning offers two advantages that make CBLO valuable in specific scenarios:

• Juvenile patients. Because the CBLO osteotomy is located below the proximal tibial growth plate, it can be safely performed on dogs whose bones are still actively growing.
• Steep tibial plateau angles. For dogs with naturally steep TPAs (often >30°), CBLO geometry allows correction without leaving the bone structurally compromised.

TPLO remains the procedure of choice for the majority of skeletally mature adult dogs, but CBLO is the right tool for juveniles and outlier anatomies. Modern CBLO systems (including LeiLOX) typically share instrumentation with TPLO and CCWO plates, which streamlines stocking for practices that offer multiple techniques.

CCWO plates (Cranial Closing Wedge Osteotomy)

CCWO is a distinct tibial osteotomy technique that uses linear (straight) cuts rather than the radial cuts of TPLO and CBLO. It is particularly useful in two scenarios:

• Juvenile patients, since the procedure is performed outside the growth zone.
• Patients with steep tibial plateau angles, where traditional TPLO geometry may be less optimal.

The LeiLOX CCWO Locking Plate System shares titanium screws and instrumentation with the TPLO and CBLO systems. For practices that offer all three osteotomy techniques, a single instrument set and screw inventory can cover the complete osteotomy lineup. Standard screws include LeiStar Locking Screws in titanium and stainless steel variants across the full size range.

TTA RAPID (Tibial Tuberosity Advancement)

The original TTA technique faced criticism over the years — concerns about implant complications, cage migration, and surgical complexity limited its adoption for some surgeons. TTA RAPID was engineered specifically to address those issues.

With more than 100,000 surgeries completed worldwide, TTA RAPID has established itself as a refined alternative to the original technique. The system offers 59 different cage sizes, which is the broadest range available in any TTA system. A dedicated “Tiny” TTA RAPID set extends the technique to small dogs and cats using 1.5/2.0 mm cages and a purpose-built saw guide — patient populations previously underserved by standard TTA equipment.

For surgeons who stepped away from TTA in earlier years due to the limitations of the original design, TTA RAPID is worth a fresh evaluation.

Patellar luxation plates

Patellar luxation is one of the most frequently encountered orthopedic conditions in dogs and cats. Historically, surgical correction could be technically challenging with inconsistent outcomes.

The RAPID LUXATION system simplifies both the technique and the supporting instrumentation. It includes “Petite” (2.0 mm), “Medium” (2.4 mm), and “Tall” (2.4 mm) plate configurations, along with titanium patella spacers in multiple thicknesses for precise correction of patellar tracking. The system shares instrumentation, screws, and patella spacers with TTA RAPID, making it economical to add patellar luxation capability to an existing TTA RAPID setup.

For complex cases involving both CrCL rupture and concomitant patellar luxation, LeiLOX TPLO Patella Luxation Spacers integrate directly with standard LeiLOX TPLO plates — addressing both conditions in a single surgery rather than a staged approach.
