Patient-Specific Instrumentation (PSI) Osteotomy Guides
In recent years, scientific literature has supported the growing use of patient-specific instrumentation (PSI) guides for knee osteotomy procedures to correct malalignment. PSI guides offer simplified preoperative planning and time savings,1 minimized patient radiation exposure,1,2 and more precision than conventional techniques,2,3 resulting in optimized clinical outcomes.4
About Arthrex PSI Osteotomy Guides
Arthrex PSI osteotomy guides provide a personalized solution for treating patients with knee malalignment and seamlessly integrate into existing osteotomy procedures. Using patient CT scans uploaded to a secure platform, the osteotomy cutting guides are 3D-printed to match patient anatomy and streamline operating room efficiency. Using customized guides increases postoperative range of motion and decreases pain levels compared with non–patient-specific osteotomy techniques.1,2 Guides are available for 4-hole plate, ContourLock™ HTO and DFO, and iBalance® HTO techniques.

ContourLock™ Distal Femoral Osteotomy (DFO) Plates and Screws
Titanium
Anatomically curved and low profile, ContourLock DFO plates are available in right and left orientations and multiple sizes, depending on the desired amount of correction. The toothless design facilitates greater flexibility through infinite correction potential up to 20 mm without compromising strength.
Titanium Femoral Opening Wedge Osteotomy Plates provide a straight-toothed option to aid in maintaining the osteotomy correction.
These plates are fixated to bone using titanium locking 6.5 mm cancellous and 4.5 mm cortical screws. Each screw can be angled to the proper anatomic orientation within a swiveling bushing before being locked.
Stainless Steel
Low-profile, stainless steel Femoral Opening Wedge Osteotomy Plates are available with a straight tooth to facilitate maintaining the osteotomy. These plates are optimal for unique anatomy that requires a customized fit with multiple bends. The plates are fixated using standard AO stainless steel 6.5 mm cancellous and 4.5 cortical screws.
All of the Femoral Opening Wedge Osteotomy Plates are designed to work in conjunction with the standard Opening Wedge Osteotomy Instruments Sets.

Tibial Opening Wedge Osteotomy Plates
Titanium
The titanium ContourLock HTO Plates were designed to be a anatomically curved and low profile. The ContourLock HTO Plate is a great choice for high demand patients needing a stronger locking construct for weight-bearing. These plates are available in wedgeless, straight, and sloped options.
The titanium Tibial Opening Wedge Osteotomy Plates feature a 4 hole design and are available with either a straight or sloped tooth to change or preserve the native tibial slope. The simplistic design facilitates minimally invasive surgery and is optimal for lower demand patients.
These plates are fixated using Arthrex titanium locking 6.5 mm cancellous and 4.5 mm cortical screws. Each screw can be angled to the proper anatomic orientation within a swiveling bushing before being locked to the plate.
