Brief summary
The purpose of this post-market clinical study is to collect long-term outcomes for DeNovo NT Graft treatment of articular cartilage lesions in the ankle in a standard clinical setting. Outcomes to be assessed include pain, function, activity levels and healthcare resource use.
Detailed description
Articular cartilage lesions in the ankle can cause significant pain and loss of function for young to middle age adults. There are several treatment options for symptomatic articular cartilage injuries depending on a patient's age, symptoms and duration of complaints in addition to the size and condition of the lesion. DeNovo NT Natural Tissue Graft is comprised of fresh particulated juvenile cartilage pieces that are secured inside articular cartilage lesions using fibrin adhesive. DeNovo NT Graft was developed due to the current need for expanded treatment options for the treatment of cartilage lesions, especially large lesions. This post-market, multicenter, longitudinal data collection study was established to collect clinical outcomes of subjects implanted with DeNovo NT Graft. Data may be obtained either retrospectively or prospectively from patients implanted or to be implanted with DeNovo NT Graft for the treatment of lesion in the ankle. Data to be collected include details of the operative procedure as well as subject pain, function, activity levels, and healthcare resource use through a five year post-operative follow-up period.
