Cartilage Lesion

The project will investigate safety, feasibility and efficiency when using Episurf Episeal talus implant in patients with osteochondral ankle injuries. Assessments includes revision rate, complications, pain, function and quality of life over two years. Ten patients (aged 20-60) who have not responded to previous treatment will participate based on informed and written consent. The project uses a prospective cohort design where the patients receive a customized surgical procedure. Data on clinical function, pain and patient satisfaction collected using the AOFAS ankle score, NRS and EQ-5D-5L questionnaire at 6 weeks, 6 months, 1 year and 2 years after the operation. The study can provide valuable insight into the treatment of ankle osteoarthritis, improve the patient's quality of life and function, and represent a step forward in orthopedic surgery, especially for younger, active patients. The results are shared with it the medical community and the general public through publications and presentations.

The goal of this randomized controlled clinical trial is to demonstrate the safety and effectiveness of the BioPoly® Partial Resurfacing Knee Implant for the treatment of cartilage defects of the distal femur in adult patients with knee pain and symptoms who are candidates for surgical intervention of the knee compared to outcomes for the control group. The primary effectiveness endpoint is Month 24 composite clinical success (CCS) defined by: * no secondary surgical intervention (SSI) and * an improvement from baseline in the Knee injury and Osteoarthritis Outcome Score (KOOS) total score (scaled 0 to 100) of at least 10 points. Researchers will compare the CCS for the investigational device group to a control group receiving the standard of care, either microfracture or debridement). Subjects randomized to the investigational group will receive the BioPoly Knee device and those randomized to the control group will receive the current standard of care, either microfracture or debridement.
