The Concave Knee Retractor is a heavy-duty orthopedic leverage instrument engineered for femoral condyle and tibial plateau exposure during knee arthroplasty. Featuring a 9.5″ (24.13 cm) length with selectable Standard or Narrow Long concave blades, it securely wraps around bone borders to shield collateral ligaments from power saws.
Product Description
The Concave Knee Retractor is a specialized orthopedic surgical retractor engineered specifically to provide exceptional bone leverage and soft-tissue protection during total knee replacement and complex knee reconstructions. Designed with an anatomically concave blade profile, this instrument conforms smoothly around the femoral condyles and tibial plateau, allowing surgical teams to retract collateral ligaments and periarticular soft tissues without slipping.
Built for heavy joint leverage, this Concave Knee Retractor model features a uniform 9.5-inch (24.13 cm) overall structural length ($105) that ensures optimal working depth while keeping assistant hands well outside the saw path. Surgeons can select between two dedicated blade geometries: a Standard Blade for broad soft-tissue displacement or a Narrow Long Blade optimized for deep, confined joint spaces and minimally invasive knee approaches. The ergonomic handle provides superior manual leverage, reducing user fatigue during long bone cuts.
Forged from high-tensile, surgical-grade stainless steel with a reflection-free satin matte finish, Retractor Maker manufactures the Concave Knee Retractor to endure heavy orthopaedic torque and repeated hospital autoclave cycles, providing knee reconstruction teams with unyielding clinical durability and performance.

Frequently Asked Questions
What are the blade and handle design advantages of the Concave Knee Retractor?
The Concave Knee Retractor is a solid one-piece instrument, so its performance comes from blade geometry and handle ergonomics. The working blade is specified as Standard Blade ($105.00) or Narrow Long Blade ($105.00), which spreads retraction force over a wider contact area and reduces point pressure on tissue. The handle is heavy-duty ergonomic handle designed for sustained leverage counter-traction, giving a secure, fatigue-resistant grip through long exposures. An overall length of 9.5″ (24.13 cm) keeps the surgeon's hand clear of the operative field. It is made from surgical-grade stainless steel (aisi 304/420) for glare-free, corrosion-resistant service.
What is the Concave Knee Retractor used for?
The Concave Knee Retractor is used in knee replacement surgery to wrap around the distal femur or proximal tibia, levering collateral ligaments and capsule away from oscillating saws during bone resection.
Which surgical procedures is it for?
It is indicated for primary Total Knee Arthroplasty (TKA), unicompartmental knee arthroplasty (UKA), revision knee reconstruction, and high tibial osteotomy (HTO).
What material and finish are used?
The instrument is forged from high-tensile surgical stainless steel with an anti-glare satin matte finish that suppresses optical reflections under surgical operating lights.
Is the Concave Knee Retractor reusable and autoclavable?
Yes. The entire Concave Knee Retractor is 100% reusable and fully validated for pre-vacuum steam autoclave cycles (134°C / 273°F).
Can components and blades be ordered separately?
Because this is a solid, one-piece forged retractor, each blade style is sold as a standalone unit. Hospitals can order both Standard and Narrow Long models to complete their knee sets.
Can custom modifications or private-label markings be ordered?
Yes. Retractor Maker provides custom blade curvatures, altered handle drops, and laser marking for hospital asset tracking upon request.
What is the standard lead time and delivery timeframe for orders?
In-stock instruments take 5 business days to inspect and dispatch, followed by 7 business days for worldwide express delivery. Back-order units take 17 to 20 business days to manufacture and 9 business days for delivery.
