The Cartilage Autograft Implantation System (CAIS) is designed as a single surgical treatment of damaged knee cartilage using the subject's own healthy cartilage obtained from a non-weight or low weight-bearing region. CAIS is indicated for the repair of articular cartilage lesions and osteochondritis dissecans (OCD) of the knee through cartilage regeneration.

Further study details as provided by DePuy Mitek:

Primary Outcome Measures:
  • To determine the safety and efficacy of CAIS compared to microfracture at 24 months post-treatment, with the primary efficacy assessment based on an analysis of superiority of CAIS to microfracture for reduction in knee pain and improvement in function [ Time Frame: 24 Months ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • To determine the safety of CAIS through 48 months [ Time Frame: 48 Months ] [ Designated as safety issue: Yes ]

Enrollment: 75

Arms Assigned Interventions
Active Comparator: 1
Randomized to Microfracture
Procedure: Microfracture
The microfracture procedure is a standard method for treatment of cartilage damage in which the surgeon will clean the site of your cartilage damage and then will make several small holes in your bone to stimulate your bone marrow with the intention to repair the damaged area with new cartilage tissue
Experimental: 2

Device: Cartilage Autograft Implantation System
A surgical treatment of damaged knee cartilage using the subject's own healthy cartilage obtained from a non-weight or low weight-bearing region

Detailed Description:
The Cartilage Autograft Implantation System (CAIS) is a kit of devices that utilizes morselized autologous hyaline cartilage harvested arthroscopically, affixed onto a synthetic, resorbable implant using a fibrin sealant and implanted in a single surgical procedure. The system is designed as a surgical treatment of damaged knee cartilage using the subject's own healthy cartilage obtained from a non-weight or low weight-bearing region.

Ages Eligible for Study:   18 Years to 55 Years   (Adult)
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • A male or female 18 to 55 years of age,
  • Has 1 or 2 focal chondral lesions, that require repair, per index knee presenting with moderate to severe knee pain. Each lesion is ≤6 mm in depth and has an area of ≥1 cm2 and ≤10 cm2. Arthroscopic confirmation indicates that the lesions are either a non-OCD lesion between grades I and III (D) or an OCD lesion between grades I and IV(A)
  • Prior failed chondral treatment is allowed if the procedure occurred > 6 months for debridement and lavage or > 1 year for marrow stimulation techniques.

Exclusion Criteria:

  • Have more than 2 chondral lesions on the index knee,
  • Bipolar lesions on the index knee,
  • Greater than 5 degrees of malalignment,
  • Require bilateral surgery
  • Have a diagnosis of clinical and/or radiographic disease of the index joint.
