Knee Orthosis (KO) with Adjustable Knee Joints

Knee Orthosis (KO) with Adjustable Knee Joints, Off-the-Shelf — Rigid Hinged Knee Brace

This prefabricated, off-the-shelf knee orthosis provides rigid support with adjustable unicentric or polycentric knee joints, designed for patients who need controlled, protected knee motion during healing. Ideal for post-surgical recovery and ligament injuries, the brace stabilizes the knee in all planes while its adjustable hinges allow clinicians to set precise flexion and extension limits — protecting repaired tissue without locking the leg completely.

Key Benefits

Controlled Motion Protection: Adjustable hinges set safe flexion/extension limits to protect healing ligaments and surgical repairs.
Rigid Multi-Plane Stability: Structured frame prevents harmful side-to-side and rotational stress on the joint.
Progressive Rehabilitation: Range-of-motion settings expand as recovery advances — one brace for the full rehab journey.
Natural Joint Movement: Polycentric hinge design follows the knee’s true anatomical motion path.
Insurance Covered: Billable under HCPCS L1833 through Medicare and most insurance plans.

Design Features

Adjustable Knee Joints

Unicentric or polycentric hinges with settable flexion and extension stops for controlled motion.

Rigid Support Frame

Dual uprights deliver medial-lateral stability and protect against varus/valgus stress.

Positional Control

Can hold the knee at a prescribed angle or permit a limited, protected arc of motion.

Off-the-Shelf Fit

Prefabricated design fits at the time of delivery — no custom fabrication required.

Secure Strap System

Multiple adjustable straps keep the brace aligned on the thigh and calf throughout the day.

Padded Comfort Liners

Cushioned, breathable padding protects skin during extended post-operative wear.

Commonly Prescribed For

Post-surgical knee recovery (ACL, PCL, MCL repair, meniscus surgery)
Ligament injuries requiring controlled motion
Knee instability & joint laxity
Post-fracture rehabilitation of the knee region
Moderate-to-severe knee sprains
Conditions requiring positional immobilization or protected range of motion

How It Works

The rigid dual-upright frame shields the knee from medial-lateral and rotational forces, while the adjustable joints govern exactly how far the knee may bend and straighten. In early recovery, clinicians can restrict motion to a narrow, safe arc — or hold the knee at a fixed position. As healing progresses, the flexion and extension stops are opened incrementally, allowing tissue to strengthen under gradually increasing load. This staged approach protects the repair while preventing the stiffness that comes from full immobilization.
