Video Summary

The video discussed a polycarbonate urethane implant and its three-year results from a randomized controlled trial combined with a single-arm study. The treatment arm consisted of 176 patients, while the control arm had 66 patients who received standard care such as bracing and injection therapies. The implant reduced load in the postmeniscectomized knee and was placed through a mini arthrotomy. Patients with grade four lesions or significant deformities were excluded. Results showed that the treatment arm had continued improvements in overall scores and pain scores at the two to three-year mark, while the control arm only saw a modest improvement. Exchanges of the implant showed positive results and patients were able to bounce back quickly. Repeat MRIs demonstrated maintained cartilage and decreased bone marrow lesions. The implant was deemed effective with no deterioration over time. The failure criteria for the study differed between the treatment and control arms.
