An Innovative Topical Medical Device with Hyaluronic Acid and Polypeptides in Patients with Reduced Knee Function.

A topical medical device, AI500, constituted of a single-chain polypeptide embedded in hyaluronic acid, was tested and evaluated in patients with reduced knee function due to osteoarthritis and other knee conditions. A total of 35 participants with reduced knee function assessed by the WOMAC Physical Function score were recruited. Four study visits were planned, from the first application at V0 to 1 week follow up at V3.

Lateral meniscus allograft transplantation without bone plugs: technique and outcomes.

Once considered a non-fundamental structure, the menisci are now known to provide several functions within the knee, including protection of articular cartilage, load-bearing, shock absorption, joint stability, joint lubrification and joint congruity functions. Meniscal tears are one of the most common lesions in knee orthopedics, and partial or total meniscectomies are commonly performed procedures in orthopedic surgery. Despite meniscectomy is well recognized to lead improvement in clinical outcomes, it has been related to early onset knee osteoarthritis and joint degeneration which are associated with pain and functional limitations.
