Next-generation DNA sequencing (NGS) techniques show the presence of bacterial DNA in surgical specimens of hip and knee arthritis, from patients undergoing first-time total joint arthroplasty, reports a study in the Journal of Bone and Joint Surgery.
You worked up a sweat playing basketball, and now your knees are screaming in pain. Or maybe your knees are in agony just from sitting all day in front of your computer. If one or both of your knees ache after too much sitting, running, jumping or squatting, you may have patellofemoral pain (PFPS).
Bone marrow edema (BME) is when normal fatty bone marrow—the spongy tissue in the center of bones—is replaced with a watery mix of fluid and blood. Also known as a bone marrow lesion, BME occurs when arthritis, an injury, or a fracture damages the normal bone structure.
Water on the knee is when fluid collects around and inside the knee joint, causing pain and swelling. Also known as knee effusion or fluid on the knee, it can occur whenever there's damage to the joint due to injury or underlying disease, such as arthritis.
For patients with symptomatic, radiographic, moderate-to-severe osteoarthritis or osteonecrosis of the hip or knee, total joint arthroplasty (TJA) should not be delayed in order to pursue additional nonoperative treatments.
