PROFESSIONAL MEDICAL KNEE SUPPORTS - The double-sided high-strength ROM hinged stabilizer and adjustable open patella design can effectively support around the patella, enhance the stability of the knee, relax the tendon, promote pain healing, and provide maximum support for the knee joint. ADJUSTABLE & DETACHABLE ROM HINGES - The ROM hinge improves the stability of the knee while also adjusting the range of motion of the knee according to the degree of injury and recovery of the knee. The ROM hinges can be adjusted and fixed from 0 to 90° extension and 0 to 150° flexion, covering the whole process of knee postoperative recovery. Perfect for ligament and tendon strain, Meniscus Tear, Sprains, Arthritis, Tendonitis Pain, ACL, MCL, LCL and knee postoperative recovery. EXCLUSIVE ADJUSTABLE PATELLAR PAD DESIGN - The traditional patella pad cannot adjust and can't adapt to different shapes of patella. Nvorliy innovatively divides the patella pad into two semicircles that can be adjusted up and down. You can apply extra pressure to the patella by adjusting the two pads separately, or adjust the shape of the pad to better fit the patella, relieve pain and disperse pressure, and protect the knee from further damage. BREATHABLE & COMFORTABLE - On the premise of ensuring stability and support, we did our best to improve its breathability and comfort. The highest level of breathable perforated neoprene and hollowed-out back design are more skin-friendly and breathable. The height-adjustable velcro straps on the top and bottom and the double silicone anti-slip strips can ensure you wear it all day without burden.
