Wide range of motion from -10° to a full 135° at the knee. Lightweight (10.9 kg, 24 lbs.) and portable. Minimizes anterior tibial translation and joint compression. Constant angular velocity over the entire range of motion. Simultaneous hip, knee and ankle motion. The L4D and L4KD put you in digital control with speed variability from 30° to 210°/minute, a wide -10° to 135 range of motion, and easy accommodation of pediatric to adult patients. The L4D and L4KD’s digital controllers features include Reverse-on-Load, end of range Pause time, Warm-Up mode, a treatment Timer, and the ability to track user hours and cycles. The controller’s unique design allows settings to be saved to a Patient Memory Key to eliminate repetitive data entry, and a lock ensures that only you make program changes. Both units quietly provide simultaneous hip and knee motion, and the L4D adds adjustable ankle motion for total-limb CPM. Indications: ACL reconstruction. Open reduction and rigid internal fixation of intra-articular, diaphyseal and metaphyseal fractures. Capsulotomy and arthrolysis for posttraumatic arthritis with restriction of motion. Synovectomy for rheumatoid arthritis and hemophilic arthropathy; Arthrotomy and drainage of acute septic arthritis. Surgical release of extra-articular contractures or adhesions (quadricepsplasty). Metaphyseal osteotomy with rigid internal fixation of tibia and femur; prosthetic replacement (arthroplasty). Reconstruction of medial collateral ligament tears of the knee using a semitendinosus tenodesis. Reconstructive surgery on bone, cartilage, tendons and ligaments. Prolonged joint immobilization. Contraindications. Do not use the device if any of the following are present: untreated or uncontrolled infection, unstable fractures or hemorrhaging.
