Additional Manufacturer Narrative
This follow-up report is being submitted to relay additional information.Updated: b4, g3, g6, h2, h3, h4, h6, and h10.Arthrofibrosis is defined as the development of fibrous scar tissue within or surrounding a joint.Arthrofibrosis is a known postoperative procedure related complication that can occur from surgical implantation of new joint replacement as well as from previous injuries or surgical procedures.Scar tissue formation is a normal healing response; however, the buildup of such can result in pain, stiffness, limited range of motion, and difficulty properly ambulating.If excess scar tissue develops, conservative measures such as exercises or physical therapy would be attempted first.If these attempts fail, surgical intervention such as manipulation under anesthesia, arthroscopic arthrolysis, or open arthrotomy would become necessary to remove the fibrous tissue and restore joint function.The synovial membrane (synovium) encloses each joint and secretes fluid to allow joints to move freely.When the synovium is irritated by debris or pathogens, it over-secrets fluid causing local pain/tenderness, inflammation, swelling, and warmth, often resulting in mobility difficulties.Synovitis is treated with steroid injections to reduce the pain and inflammation or by arthroscopic or open synovectomy.Hemarthrosis is a condition of articular bleeding, that is into the joint cavity.This can occur after and injury, bleeding disorder, or surgery.Common symptoms include pain, swelling, and decreased range of motion of the involved joint.Hemarthrosis can be treated at home using the rice method rest, ice, compression, and elevation however, when patient do not respond to conservative measures embolization maybe performed.
