title: [Matrix-augmented autologous chondrocyte implantation in the knee--arthroscopic technique].
abstract: OBJECTIVE
  Arthroscopic implantation of resorbable, three-dimensional scaffolds for the treatment of full-thickness cartilage defects.
  
  
  METHODS
  Full-thickness cartilage defect mainly in the knee joint.
  
  
  METHODS
  Advanced osteoarthritis, rheumatoid arthritis, avascular osteonecrosis.
  
  
  METHODS
  Debridement of the defect, assessment of the defect size, sizing of the implant, implantation into the joint, and fixation.
  
  
  METHODS
  Continuous active and passive motion, pain-adapted weight bearing with crutches, possibly toe-touch loading depending on size and localization of the defect.
  
  
  RESULTS
  After 2 years, good and excellent results in 80% of the cases with femoral cartilage defects on the modified Cincinnati Knee Rating Scale. Inferior results for defects of the patella and tibia.
