The use of a polyurethane meniscal scaffold in patients with a
symptomatic meniscus deficit had a good functional outcome at 5 years after
surgery. However, the implanted scaffolds did not present normal meniscal tissue
with MRI, and the implant volume was considerably less than expected. The fact
that most of patients included received different concomitant procedures during
scaffold implantation introduces a degree of performance bias into the results.
