This study is to assess the effect of Renuva® on fat pad regeneration in patients with Fat pad Impingement
The fat pad of the knee works to stabilize the patella and releases cytokines, growth factors, and stem cells. These cytokines, growth factors, and stem cells exhibit anti-inflammatory, anabolic effects that can be recruited to heal the articular tissues of the knee and ameliorate their catabolic effects during osteoarthritis (OA).
The majority of the current treatments for fat pad impingement (FPI) and its sequelae are primarily symptom-modifying, and structure-modifying therapies both at the joint and peri-articular structures levels cannot be overemphasized.
Renuva® (MTF Biologics) is a Food and Drug Administration approved, off-the-shelf, injectable decellularized allograft adipose matrix (AAM) used to increase volume in adipose tissue. Once injected, native cell populations infiltrate the AAM, and over time, the AAM remodels into native tissue and stimulates both adipogenesis and angiogenesis within the tissue.
Our specific aim is to assess the effect of Renuva® on fat pad regeneration in patients with FPI. The investigators hypothesize that injection of Renuva® into a diseased fat pad of the knee increase the volume of the fat pad and reduce any hemorrhage, edema or fibrosis present, when pre-to post-treatment images are compared.
