A post-op knee brace is a medical device that is used to immobilize and protect the knee joint after surgery. It is typically used after procedures such as ACL reconstruction, knee replacement surgery, or meniscus repair. The brace is designed to provide support and stability to the knee joint, while also allowing for controlled movement as the patient recovers. Post-op knee braces are typically made of lightweight materials such as plastic or aluminum, and are adjustable to fit different leg sizes and shapes. They are designed to be worn for extended periods of time, and are often used in conjunction with other forms of physical therapy to help patients regain strength and mobility in the affected leg. The brace typically consists of a rigid frame that is secured to the leg with straps or Velcro, and may also include additional pad.
