Study summary

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.

Read the 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.

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

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.

Interventions

  • ProcedureMicrofracture

    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

  • DeviceCartilage 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

What researchers measure

Primary outcomes

  1. 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

Secondary outcomes

  1. To determine the safety of CAIS through 48 months

    Time frame: 48 Months

The record gives a start of Jul 2010, a primary completion of Dec 2014 and a completion of Dec 2014. It does not say whether these dates are actual or estimated.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 3, 2016, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
