Conditions
Outcome Measures
Primary Outcomes (1)
Number of participants with Adverse Events
The primary efficacy analysis in this study is to ascertain that the incidence of at least one subject having any of the seven identified clinical undesirable side effects is lower than 38 % (risk profile of the comparator) up to the 24 months analysis in the PP population. This will be analyzed with a one-side exact binomial test on significance level 0.05

Eligibility Criteria
You may qualify if:
- Male or female
- Age 30 ≤ 65 years
- Chondral defects of the femoral cartilage ICRS grade 3 (severely abnormal cartilage defects \> 50% of the cartilage depth) or grade 4 (severely abnormal, through the cartilage depth) on medial or lateral femoral condyles
- Cartilage lesion area \< 3.2 cm2 (diameter \< 2 cm)
- Failed earlier conservative or surgical interventions such as lavage, abrasions, drilling or microfracture
- VAS-pain symptom \>40 for more than 6 months
- The arthroscopic finding corresponds to the expected; size of cartilage lesion is correct and no other significant pathology (see CIP, "Intra-operative check-list", Appendix I)
- Capable of completing self-administered questionnaires
- Willing to comply with the follow-up requirements of the study
- Signed informed consent
You may not qualify if:
- BMI ≥ 35 kg/m2 (severe obesity)
- Instability or deficiency of soft tissues, vascular or muscular insufficiency
- Metabolic disorders which may impair bone formation
- Diabetes mellitus
- Smokers
- Diagnosis of a concomitant knee injury which the Investigator appreciates may interfere with study participation (i.e. may confound efficacy assessment or healing at the involved knee joint level)
- Irresolvable joint pain or loss-of-function with an undeterminable cause
- Diagnosis of a concomitant meniscal injury in involved knee that requires surgical intervention
- Loss of joint space on standing radiographs (≥ 1 on Ahlbäck-scale (0-5))
- Avascular necrosis
- Infections, systemic or local
- Known metal allergies
- History of inflammatory arthritis
- Pregnancy
- Pacemaker implant
- +4 more criteria
