- •Is between age 30 and 75 years (inclusive) at the time of study treatment
- •Has neutral alignment ±5º of the mechanical axis, as measured from the angle formed by a line drawn from the center of the femoral head to the medial tibial spine and a line drawn from the medial tibial spine and the center of the ankle joint
- •Has ≥ 2 mm intact medial meniscal rim capable of being fitted with a NUsurface® device
- •Is able to do the study required follow-up visits, questionnaires, X-rays and MRI's

排除标准
- •Has a symptomatic knee because of a tear that could be addressed by a repeat partial meniscectomy leaving > 4 mm of medial meniscus rim
- •Has evidence of a Outerbridge Grade IV cartilage loss on the medial tibial plateau or femoral condyle that potentially could contact a NUsurface implant (e.g., a focal lesion > 0.5 cm2 correlating to a circular defect of > 8 mm in diameter)

- •Has a laxity level of more than Grade II (IKDC), primary or secondary to an injury of the anterior cruciate ligament (ACL) and/or posterior cruciate ligament (PCL) and/or lateral collateral ligament (LCL) and/or medial collateral ligament (MCL)
- •Has significant trochlear dysplasia, patellar instability or symptomatic patellar misalignment
- •Has patellar compartment pain and Grade III or Grade IV Outerbridge cartilage score in the patellar compartment.
- •Compared to a normal knee, has obvious radiological evidence of medial femoral squaring, anatomical variance in the medial tibial plateau, or irregularly shaped cartilage surface
- •Had an ACL reconstruction performed < 9 months prior to study treatment
- •Has a BMI > 32.5 at the start of study treatment
- •Decides to receive (if eligible and an option) allograft medial meniscus transplantation

- •Anticipates having another lower extremity surgery during the study period
- •Is contraindicated for hyaluronic acid injections (i.e., patients with known hypersensitivity [allergy] to hyaluronan [sodium hyaluoronate] preparations); patients having knee joint infections or skin diseases or infections in the site of possible injections
- •Is contraindicated for corticosteroid injections (i.e., patients with allergy to any of the components or with idiopathic thrombocytopenic purpura)
- •Has received any corticosteroid knee injections ≤ 3 months prior to study treatment
- •Has chondrocalcinosis
