Further study details as provided by Instituto Nacional de Rehabilitacion:

Primary Outcome Measures:
  • Change from baseline to different periods in T2 Mapping for cartilage lesions after treatment. [ Time Frame: 3, 6, 9, 12, 18, 24 36 months ]
    Special magnetic resonance imaging technique for measurement of collagen and water content, it is expressed in milliseconds.

  • Change of baseline to different periods in Clinical evaluation [ Time Frame: 0, 10, 30 days, 3, 6, 9, 12, 24, 36 months ]
    Clinical assessment with validated knee scores, and adverse effects register are taken.

Enrollment: 10
Study Start Date: December 2008
Study Completion Date: December 2012
Primary Completion Date: December 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Chondrocyte implantation Device: Arthroscopic matrix encapsulated chondrocyte implantation
Each implant of collagen scaffold contains approximately 6,000,000 autologous chondrocytes. This constructs of 10 mm diameter are implanted arthroscopically at the defect.

Detailed Description:
Injuries to the articular cartilage of the knee are common. They produce pain and deteriotation of patients' quality of life. The management of focal chondral lesions continues to be problematic for the treating orthopaedic surgeon. Although many treatment options are currently available, none fulfill the criteria for an ideal repair solution: a hyaline repair tissue that completely fills the defect and integrates well with the surrounding normal cartilage. Autologous chondrocyte implantation is a relatively new cell-based treatment method for full-thickness cartilage injuries that in recent years has increased in popularity, with different studies showing promising results. Typically, this implantation is performed in an open-surgery fashion. In our study the implantation of in-house autologous chondrocyte culture is done arthroscopically, situation that may offer advantages in surgery associated morbidity and patient recovery.
