Brief summary

This study is to assess the effect of Renuva® on fat pad regeneration in patients with Fat pad Impingement

Detailed description

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.

Design outcomes

Primary

MeasureTime frameDescription
Knee MRI measurements of fat pad thickness (mm)6 MonthsKnee MRI will be taken at 6 months post injection to compare the fat pad thickness (mm) to the MRI taken prior to the injection of Renuva.
Knee MRI measurements of fat pad surface area (mm2)6 MonthsKnee MRI will be taken at 6 months post injection to compare the fat pad surface area (mm2) to the MRI taken prior to the injection of Renuva.
Knee MRI measurements of fat pad volume (mm3)6 MonthsKnee MRI will be taken at 6 months post injection to compare the fat pad volume to the MRI taken prior to the injection of Renuva.

Secondary

MeasureTime frameDescription
Knee injury and Osteoarthritis Outcome Score (KOOS) Function in Sport and Recreation (Sport/Rec) patient reported outcomeBaseline, 1 month, 3 month and 6 monthKOOS Sport/Rec evaluates short-term and long-term function in sports and recreation in subjects with knee injury and osteoarthritis. Scores range from 0-100 where 100 represents no knee related issues in regards to sports or recreation activity.
Knee injury and Osteoarthritis Outcome Score (KOOS) Pain patient reported outcome questionnaire6 MonthsKOOS Pain evaluates short-term and long-term pain in subjects with knee injury and osteoarthritis. Scores range from 0-100 where 100 represents no knee pain.
Knee injury and Osteoarthritis Outcome Score (KOOS) Pain patient reported outcomeBaseline, 1 month, 3 month and 6 monthKOOS Pain evaluates short-term and long-term pain in subjects with knee injury and osteoarthritis. Scores range from 0-100 where 100 represents no knee pain.
Knee injury and Osteoarthritis Outcome Score (KOOS) knee related quality of life (QOL) patient reported outcomeBaseline, 1 month, 3 month and 6 monthKOOS QOL evaluates short-term and long-term knee quality of life in subjects with knee injury and osteoarthritis. Scores range from 0-100 where 100 represents no knee related issues in regards to quality of life.
Knee injury and Osteoarthritis Outcome Score (KOOS) Symptoms patient reported outcomeBaseline, 1 month, 3 month and 6 monthKOOS symptoms evaluates short-term and long-term symptoms in subjects with knee injury and osteoarthritis. Scores range from 0-100 where 100 represents no knee symptoms.
