Additional Manufacturer Narrative
(b)(4).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.If any further information is found which would change or alter any conclusions or information, a supplemental report will be filed accordingly.Zimmer biomet will continue to monitor for trends.Multiple mdr reports were filed for this event, please see associated reports: 3007963827-2023-00266.3007963827-2023-00267.0002648920-2023-00240.
Event or Problem Description
It was reported that the patient underwent an initial right total knee arthroplasty.Approximately 6 weeks post implantation, the patient underwent a manipulation under anesthesia due to stiffness and arthrofibrosis.Attempts have been made and no further information has been provided.
