The PS Knee Prosthesis Instrument Set-II represents the next evolution in surgical instrumentation for Posterior Stabilized (PS) Total Knee Arthroplasty. Building on the success of the first-generation set, the Series II focuses on improved surgical efficiency and enhanced ergonomic control. It features a refined Notch Cutting Guide with more stable anchoring points and Adjustable Femoral Sizing Guides that utilize laser-etched markers for superior visibility. The set allows for both gap-balancing and measured resection philosophies, providing the surgeon with the versatility needed to address complex deformities. Manufactured from high-grade Surgical Stainless Steel, these instruments facilitate accurate distal and posterior femoral resections, ensuring the PS cam-post mechanism is aligned flawlessly for optimal joint kinetics and long-term durability.

Product Description
The second-generation intercondylar notch guide features enhanced stabilization pins and a more rigid cutter track, minimizing instrument deflection during the critical intercondylar box creation.
Redesigned impaction and orientation handles provide a more tactile grip and better balance, reducing hand fatigue and improving the accuracy of instrument positioning under surgical loads.
All gauges and alignment rods feature high-contrast laser etching, improving clarity under bright OR lights and ensuring that intraoperative measurements are interpreted correctly every time.
The sterilization tray is organized for maximum workflow efficiency, with high-durability instrument inserts that simplify cleaning, sterilization, and rapid tool identification during surgery.
Indicated for creating precise distal, posterior, and chamfer bone cuts on the femur to accommodate the specific geometry of modern Posterior Stabilized (PS) knee implants.
Used to accurately resect the femoral notch, providing the necessary housing for the PS cam mechanism while preserving critical medial and lateral bone stock.
Provides modular spacers and calipers for the accurate assessment of the extension and flexion gaps, essential for achieving a stable, balanced knee replacement.

The PS Knee Prosthesis Instrument Set-II is an advanced collection of surgical guides and cutters designed to shape the knee joint for a Posterior Stabilized prosthetic. Its primary innovation over the first generation is the refined accuracy of the femoral box resection and improved tactile feedback of the alignment jigs. It acts as a high-precision navigational tool, turning the surgeon's plan into repeatable bone cuts.
This instrument set is applied during end-stage knee reconstruction where the PCL is not retained. It is particularly useful in patients with severe valgus or varus deformities where precise ligament gap balancing—supported by the set’s modular spacer blocks—is the key to a successful outcome.
The main advantage is surgical workflow optimization. By reducing the number of manual steps and improving instrument stability, the Set-II helps decrease the total operative time. Shorter procedures reduce the duration of anesthesia and the time the open surgical field is exposed, directly supporting better patient recovery and reduced infection risks.
The instruments are biomechanically focused on achieving "neutral alignment." The alignment guides reference the center of the femoral head and the center of the ankle. This ensures that the cuts result in a knee joint that carries the patient's weight centrally, mimicking natural anatomy and preventing eccentric wear on the tibial insert post-operatively.
The technique involves using the sizing caliper to establish femoral rotation based on the posterior condyles. The notch guide is then placed centrally on the distal femur, and a power saw or specific notch cutter removes the bone notch. This creates a clean, vertical slot that allows the PS femoral box to seat with a stable friction fit before cementing.
Accurate bone resection facilitated by the Set-II ensures that the permanent implants sit flush against healthy bone. This maximizes the cement-bone bond strength, allowing for early weight-bearing and aggressive physical therapy. Patients can typically bend their knee further post-operatively due to the correct femoral rollback achieved by the accurate notch cut.
The PS Knee Prosthesis Instrument Set-II is an essential upgrade for high-volume TKA centers. Its blend of ergonomic design, advanced material quality, and specialized notch-cutting precision makes it a superior choice for achieving consistent, predictable outcomes in modern knee replacement surgery.
Improvements focus on faster quick-release couplings, higher-contrast laser markings for measurement, and a more stable anchoring system for the intercondylar notch guide, reducing intraoperative alignment errors.
Measured resection focuses on replacing the amount of bone removed. Gap balancing focuses on achieving equal spaces in flexion and extension. This instrument set is designed to accommodate both philosophies intraoperatively.
While primary resections are possible, complex revisions with bone loss usually require supplemental long-stem drills and augments not typically found in a standard primary PS instrument tray.
No, cutting blocks are manufactured with tight slot tolerances to guide a saw blade. If they become damaged or deformed, they should be replaced to ensure surgical precision is not compromised.
