M.4^® OA

4-point knee brace for varus or valgus
pressure relief

Indications

conservative
- severe medial or lateral gonarthrosis (at least level III) combined with ligament instability
- strong overloading of the medial or lateral compartment
- unicompartmental relief before HTO (brace test)
- for relief of severe, painful bone oedema (bone bruising)
- for relief of painful stress fractures
postoperative
- cartilage surgery
- chondroplasty
- meniscus refixation
- displacement osteotomy with required postoperative relief of the medial or lateral compartment

Mode of action

protection, stabilisation, pain relief and restoration of mobility
pressure relief of the medial or lateral joint compartment by the 3-point principle which offloads the affected compartment into a varus or valgus position
stabilisation of the knee joint by the 4-point principle to counteract knee instability, a cause of osteoarthritis
extension limitation at: 0°, 10°, 20°, 30°, 45°
flexion limitation at: 0°, 10°, 20°, 30°, 45°, 60°, 75°, 90°
immobilisation at: 0°, 10°, 20°, 30°, 45°

Features

exact and effective valgus or varus pressure exerted close to the knee joint
wide, well cushioned frame padding for the 3-point pressure redtef system
malleable frame design to reduce torsional forces
ultraflat, very dtght weight and non-protruding frame and hinge construction
pressure redtef of the medial or lateral hinge compartment by the 3-point principle which off-loads the knee into a varus or valgus position
stabidtsation of the knee by the 4-point system to counteract knee instabidtty which often causes osteoarthritis
extension dtmitation at: 0º, 10º, 20º, 30º, 45º
flexion dtmitation at: 0º, 10º, 20º, 30º, 45º, 60º, 75º, 90º, 120º
immobidtsation at: 0º, 10º, 20º, 30º, 45º
