Brief Summary
The Hyalex First-in-Human Study is a prospective, multicenter, open-label, single-arm, 2-phase, first-in-human study to evaluate the safety and technical performance of the HYALEX Knee Cartilage System for replacement of loss of articular cartilage and bone of the knee femoral condyles in symptomatic patients who require surgical treatment.

Outcome Measures
Primary Outcomes (2)
Freedom from implant rejection and infection.
Assess the safety (implant rejection, infection) and tolerability of the Hyalex Cartilage Implant.
Through 24 months.
Change in the Knee Injury & Osteoarthritis Outcome Score (KOOS) from baseline 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.
Through 12 months.
Study Arms (1)
Hyalex Cartilage System
EXPERIMENTALImplantation of Hyalex Cartilage Knee Implant
Interventions
Implantation of Hyalex Cartilage Knee Implant.
Eligibility Criteria
You may qualify if:
- years.
- Body Mass Index (BMI) ≤ 35.
- Singular treatable joint surface lesion, ICRS Grade 3 or 4, located on the medial or lateral femoral condyle.
- Symptomatic, single treatable area 1 - 3.8cm2.
- Knee Injury and Osteoarthritis Outcome Score (KOOS) pain subscale score between 20 and 65.
- Stable knee.
- Non-responsive to a minimum of 3 weeks of conservative treatment, consisting of non-steroidal anti-inflammatory drugs and/or physical therapy.
- years.
- Body Mass Index (BMI) ≤ 35.
- Up to three treatable joint surface lesion(s), ICRS Grade 3 or 4, located on the medial or lateral femoral condyle(s).
- Symptomatic total treatable area 1 - 10cm2.
- Knee Injury and Osteoarthritis Outcome Score (KOOS) pain subscale score between 20 and 65.
- Stable knee.
- Non-responsive to a minimum of 3 weeks of conservative treatment, consisting of non-steroidal anti-inflammatory drugs and/or physical therapy.
You may not qualify if:
- Known allergy to polyurethanes, bone cement, acrylic, or titanium.
- Lack of 2mm of healthy cartilage (ICRS Grade 0 or 1) and 2mm of vital bone wall on all sides of the implant site.
- Osteochondral defect affecting subchondral bone more than 11mm in depth from adjacent non-defect articular surface.
- Bipolar cartilage lesions involving patellar or tibial lesions ICRS Grade 3 - 4 opposite the lesion intended for treatment.
- Insufficient bone stock or bone density determined intra-operatively preventing implant press fit.
- Kellgren and Lawrence (KL) grade 3 or 4 on standing radiographs as defined:
- Hip-knee-ankle (HKA) angle of greater than +/- 5 degrees (varus or valgus malalignment \> 5 degrees) on standing X-ray.
- Lack of normally functioning contralateral knee that restricts activity.
- Insufficiency fracture of the femoral condyle or tibial plateau.
- Recent Osteochondritis Dissecans within 1 year.
- Diagnosis of a concomitant knee injury which the investigator believes may interfere with study participation or confound effectiveness assessment.
- Any known systemic cartilage and/or bone disorder, such as but not limited to osteoporosis, chondrodysplasia or osteogenesis imperfecta.
- A symptomatic musculoskeletal condition in the lower limbs that could impede effectiveness measurements in the target knee.
- Any known tumor of the treatment knee.
- Prior radiation therapy to the knee joint.
