Product Overview

This comprehensive knee surgery positioning system encompasses the full range of devices required for total knee arthroplasty, knee ligament reconstruction, knee arthroscopy, and general knee surgery — from the multi-joint physician hand frame that positions the surgeon's hands and arms for optimal ergonomics during prolonged procedures, to the complete family of knee supports and knee joint knife holders that provide stable, adjustable, and lockable positioning of the patient's knee at the exact angle and height required for each surgical approach.

The system is built on stainless steel and aluminum alloy frames for corrosion resistance, structural rigidity, and autoclave compatibility, with patient-contact surfaces available in either PU leather pads for standard procedures or all-carbon-fiber pads for cases requiring full X-ray transparency during intraoperative fluoroscopy. Every knee support and knife holder in the range features adjustable height, spacing, and angle to accommodate patients of all body sizes and surgical approaches — from standard total knee arthroplasty to complex revision procedures requiring extreme flexion or extension angles.

A defining feature of the entire knee support family is the knob-lock positioning mechanism — the scrub nurse can lock the knee at the desired angle and position with a single knob, then release it intraoperatively when the surgeon requires the knee to be moved to a different angle during the procedure. This single-knob lock-and-release design eliminates the need to disassemble or unbolt multiple fasteners when repositioning the knee mid-procedure, enabling rapid, smooth intraoperative angle changes that maintain surgical workflow efficiency while keeping the knee absolutely stable at every locked position.

Key Features & Clinical Advantages

Stainless steel and aluminum alloy frame construction — Structural components are fabricated from medical-grade stainless steel or lightweight aluminum alloy, providing excellent corrosion resistance, long-term durability, and full autoclave compatibility across repeated sterilization cycles.
PU leather and all-carbon-fiber pad options — Patient-contact surfaces are available in PU leather for standard procedures or all-carbon-fiber for cases requiring full X-ray transparency, allowing facilities to select the pad material that matches their imaging requirements for each procedure type.
Adjustable height, spacing, and angle — Every knee support and knife holder features multi-axis adjustability, allowing the surgical team to configure the exact knee position — height, lateral spacing, and flexion/extension angle — required for each patient's anatomy and each surgical approach.
Single-knob lock-and-release mechanism — The knee position is locked by a single knob that the scrub nurse can release intraoperatively when the surgeon needs to change the knee angle — enabling rapid, tool-free repositioning without disrupting the sterile field or removing any components.
Universal operating table compatibility — All models mount to standard operating table side rails from any manufacturer, eliminating the need for brand-specific adapters and simplifying procurement for multi-brand hospital environments.
Full X-ray transparency (carbon-fiber models) — The all-carbon-fiber knee support delivers complete radiolucency with zero imaging artifact, enabling intraoperative fluoroscopy of the knee joint during minimally invasive orthopedic procedures without removing or repositioning the support.
Integrated ammonia ester comfort adjustment (hand frame) — The physician hand frame features integrated ammonia ester padding that allows the surgical team to adjust the distance between support surfaces before and after surgery, ensuring ergonomic comfort for the surgeon's hands and arms throughout the procedure.

Model Variants & Specifications

Multi-Joint Physician Hand Frame

FP-020-A1 — Multi-Joint Physician Hand Frame
A sophisticated multi-joint positioning frame designed to support the surgeon's hands, wrists, and elbows during prolonged knee surgery and other procedures requiring precise upper-limb positioning. The frame is built on two powerful universal fixators that mount to the operating table side rail, providing a rigid, stable base from which two wrist-elbow joint supports extend to cradle the surgeon's forearms and hands at the optimal working height and angle. The universal fixators allow the entire assembly to be positioned anywhere along the side rail and locked firmly in place, accommodating surgeons of different heights and arm lengths.

The wrist-elbow joint supports are padded with soft polymer comfort pads that distribute pressure evenly across the surgeon's forearms and wrists, preventing fatigue and nerve compression during procedures lasting several hours. The integrated ammonia ester padding allows the surgical team to adjust the distance between the support surfaces before surgery to match the surgeon's preferred working posture, then readjust after surgery for comfortable rest — a feature that recognizes the ergonomic demands placed on the surgical team during lengthy knee replacement and reconstruction procedures.

The multi-joint design provides articulation at multiple points — the universal fixator base, the vertical height adjustment, the horizontal reach adjustment, and the wrist-elbow support angle — creating a fully customizable support system that can be configured to match the exact ergonomic requirements of each surgeon and each procedure. This reduces surgeon fatigue, improves precision during delicate ligament balancing and component positioning, and contributes to better surgical outcomes over the course of long arthroplasty cases.

Standard Knee Support

FP-021-A1 — Standard Knee Support (Entry-Level)
The preferred entry-level knee support for knee replacement and general knee support procedures, built on a 16 mm diameter rod with a 500 mm length and a 300 mm transverse PU pad that provides broad, comfortable support for the patient's lower leg and knee. The 16 mm rod provides sufficient rigidity to prevent deflection under the weight of the lower leg while remaining compatible with standard operating table side-rail clamps. The 500 mm length provides ample support surface from the mid-thigh to the proximal calf, and the 300 mm transverse pad width distributes pressure across a broad area of the lower extremity, preventing focal compression of the peroneal nerve and popliteal vessels.

The PU leather pad surface is easy to wipe clean and disinfect between cases, and the high-density sponge core resists compression set during prolonged procedures. The height, spacing, and angle of the support are fully adjustable via the side-rail mounting and the multi-axis adjustment mechanism, allowing the surgical team to position the knee at the exact height and angle required for the procedure — whether for standard total knee arthroplasty, unicompartmental knee replacement, or general knee surgery. The single-knob lock mechanism holds the knee firmly in position and can be released by the scrub nurse intraoperatively when the surgeon requires a different knee angle.

Adjustable Knee Support

FP-021-B1 — Adjustable Knee Support (with Knee-Joint Positioning Brackets)
An upgraded knee support that shares the same 16 mm rod diameter and 500 mm length as the standard FP-021-A1 but adds knee-joint positioning brackets for enhanced adjustability. The positioning brackets allow the lateral spacing and angular orientation of the knee support to be fine-tuned independently of the base rod adjustment, providing a second level of precision that is particularly valuable in complex knee procedures where the exact position of the knee joint — not just the general leg position — must be controlled with high accuracy.

The positioning brackets enable the surgical team to adjust the mediolateral position of the knee support to match the patient's leg alignment, ensuring that the knee joint center is positioned precisely over the support's pivot point — critical for procedures requiring controlled varus/valgus stress testing, ligament balancing, and component alignment verification during total knee arthroplasty. The single-knob lock mechanism holds the adjusted position firmly and can be released intraoperatively by the scrub nurse when repositioning is needed.

Knee Joint Knife Holder

FP-021-C1 — Knee Joint Knife Holder (for Arthroplasty)
A specialized knee support designed specifically for knee arthroplasty procedures, built on a 16 mm rod with a 500 mm length and a 250 mm transverse PU pad — narrower than the standard knee support's 300 mm pad to provide enhanced surgical access around the knee joint during arthroplasty. The reduced pad width creates additional working space for the surgeon's instruments and hands around the medial and lateral aspects of the knee, which is essential during the bone cuts, trial reduction, and component implantation phases of total knee arthroplasty where unobstructed access to the joint line from multiple angles is critical.

Despite the narrower pad, the 250 mm width still provides adequate support surface for the patient's lower leg, distributing pressure evenly and preventing focal compression. The height, spacing, and angle are fully adjustable, and the single-knob lock mechanism provides secure intraoperative positioning that can be released by the scrub nurse when the surgeon needs to change the knee angle — for example, transitioning from extension for the tibial cut to flexion for the femoral cut during the arthroplasty sequence.

All-Carbon-Fiber Knee Support

FP-021-D1 — All-Carbon-Fiber Knee Support (290 × 175 × 120 mm, X-Ray Transparent)
A fully radiolucent knee support constructed entirely from carbon fiber, measuring 290 × 175 × 120 mm, designed for minimally invasive orthopedic cases where intraoperative fluoroscopy is required without removing or repositioning the knee support. The all-carbon-fiber construction delivers complete X-ray transparency with zero imaging artifact — enabling the surgeon to obtain real-time fluoroscopic images of the knee joint, implant position, and bone cuts during minimally invasive knee procedures without the streak artifact and beam hardening that metallic support frames would produce.

The 290 × 175 × 120 mm dimensions provide a compact yet supportive platform that cradles the knee joint while maintaining the radiolucent window needed for imaging. This model is particularly valuable for minimally invasive total knee arthroplasty (MIS-TKA), unicompartmental knee arthroplasty (UKA), and percutaneous knee procedures where intraoperative imaging is used to verify component alignment, bone cut accuracy, and implant positioning in real time. The carbon fiber construction is lightweight, corrosion-resistant, and compatible with standard disinfection protocols.

FP-021-D2 / FP-021-B2 — All-Carbon-Fiber Knee Support (Custom Sizes)
Additional all-carbon-fiber knee support variants available in other sizes on request, allowing facilities to specify custom dimensions to match their specific procedural requirements, patient population, or imaging equipment configurations. The custom-size option ensures that facilities performing specialized minimally invasive knee procedures — such as pediatric knee surgery, bariatric knee arthroplasty, or complex revision cases requiring non-standard support geometries — can obtain a carbon-fiber knee support that is precisely tailored to their needs while maintaining the full X-ray transparency that makes the carbon-fiber platform essential for image-guided knee surgery.

Clinical Applications

This knee surgery positioning system supports procedures across the full spectrum of knee surgery:

Total knee arthroplasty (TKA) — The standard or adjustable knee support positions the patient's leg at the optimal height and angle for bone cuts, trial reduction, component implantation, and alignment verification; the single-knob lock enables rapid intraoperative angle changes between extension and flexion positions.
Unicompartmental knee arthroplasty (UKA) — The all-carbon-fiber knee support provides full radiolucent access for intraoperative fluoroscopy during minimally invasive UKA, enabling real-time verification of component position and alignment without removing the support.
Minimally invasive knee arthroplasty (MIS-TKA) — The carbon-fiber knee support's radiolucency and compact profile provide the imaging access and surgical exposure needed for minimally invasive approaches where the surgical window is smaller and imaging verification is more critical.
Knee ligament reconstruction (ACL/PCL) — The adjustable knee support with positioning brackets enables precise control of knee flexion angle during graft tunnel drilling, graft passage, and fixation — angles that must be exact to ensure proper graft isometry and tension.
Knee arthroscopy — The knee joint knife holder provides stable support at the working angle while the narrower 250 mm pad creates additional space for arthroscopic instruments and the surgeon's hands around the joint.
Revision knee arthroplasty — The adjustable knee support's multi-axis positioning capability accommodates the complex, non-standard leg positions often required in revision procedures where scar tissue, bone loss, and deformity create unique positioning challenges.
High tibial osteotomy (HTO) — The knee support positions the leg at the precise angle required for the osteotomy cut and fixation, with the single-knob lock maintaining the position during drilling and plate application.
Knee fracture fixation — The standard or adjustable knee support stabilizes the lower extremity during percutaneous and open fixation of distal femur, proximal tibia, and tibial plateau fractures, with the knob-lock mechanism allowing intraoperative repositioning for different imaging angles.
Varus/valgus stress testing — The adjustable knee support with positioning brackets enables controlled, reproducible stress testing at specific flexion angles during ligament assessment and balancing.
Knee manipulation under anesthesia — The single-knob lock-and-release mechanism allows the surgeon to lock the knee at a specific angle, perform the manipulation, then release and reposition as needed — all without disassembling any hardware.
Surgeon ergonomic support — The multi-joint physician hand frame reduces surgeon fatigue during lengthy knee arthroplasty cases by providing adjustable, comfortable support for the surgeon's hands, wrists, and elbows — improving precision during delicate ligament balancing and component positioning steps.
Bariatric knee surgery — The adjustable height, spacing, and angle range of the knee supports accommodates larger patients whose leg dimensions and weight exceed the capacity of fixed-geometry support systems.
