About this trial
A multicenter, open-label, single-arm, pivotal study to evaluate the safety and effectiveness of the HYALEX Freestyle Resurfacing System for replacement of loss of articular cartilage and bone of the knee femoral condyles in symptomatic patients who require surgical treatment, will be enrolled in the study and undergo implantation of the HYALEX Freestyle Resurfacing Implant.

22-70 years.
Body Mass Index (BMI) ≤ 40.
Up to two treatable joint surface lesion, ICRS Grade 3 or 4, located on the medial and/or lateral femoral condyle.
Up to 2 implants (one implant per condyle) to treat up to 2 individual symptomatic lesions with a total summative area up to 4.52cm2 / condyle.
Disqualifiers
Known allergy to polyurethanes, bone cement, acrylic, or titanium.
Lack of 2mm of cartilage (ICRS Grade 0 to 2) and 2mm of vital bone wall on all sides of the implant site.

Trial outcomes
Primary outcomes
Composite Primary Endpoint
* A clinically significant improvement in KOOS Pain score; * A clinically significant improvement in KOOS ADL score; * Lack of treatment-related SAEs; and * Absence of secondary surgical intervention defined as HYALEX Freestyle Resurfacing Implant removal or revision due to a treatment-related finding.
Change in the Knee Injury & Osteoarthritis Outcome Score (KOOS) at 12 months.
The KOOS assesses patient pain, other symptoms, function in daily living, function in sport and recreation, and knee related quality of life. Scores range from 0 to 100 with a score of 0 indicating the worst possible knee symptoms and 100 indicating no knee symptoms.
