|Degenerative Lesion of Articular Cartilage of Knee||Procedure: ADSC Application Procedure: Microfracture||Not Applicable|
Patients enrolled in the ADSC cohort will undergo the following procedures: arthroscopic resection of approximately 5cc of the infrapatellar fat pad using a motorized shaver (standard use in arthroscopy). Fat will be collected in a sterile Aquavage Collection System (AV1200, MD Resources, Livermore, CA) and kept sealed until processing. Fat will then immediately be processed in the Harvest Adiprep System to separate a population of ADSCs. This system concentrates an average of 5 x 105 cells/ml. All specimens will be processed using routine sterile procedures within the operating room; cells destined for implantation will not leave the operating room. Concurrently, patients will undergo arthroscopy and similar preparation of the chondral defect and removal of the calcified cartilage layer. However, no puncture of the subchondral bone will be performed. A layer of fibrin glue (Tisseel) will be placed at the base of the defect to seal off any bleeding from the subchondral plate followed by the application of the acellular dermal matrix (Allopatch HD, MTF Corporation, Edison, NJ, USA)and ADSCs. An additional layer of Tisseel will then be applied over the cells and matrix. No additional fixation will be applied. The matrix and cells will be recessed below the articular surface by an average of 1mm.
They will then complete outcome questionnaires and additional MRI scans at 6, 12, and 24 months post-operatively.

Experimental: ADSC Application
Patients undergo an arthroscopic surgical procedure, ADSC application, followed by physical therapy.
Procedure: ADSC Application
Patients will undergo arthroscopic resection of approximately 5cc of the infrapatellar fat pad, which will be collected for processing for a population of ADSCs. Patients will undergo arthroscopy and preparation of the chondral defect and removal of the calcified cartilage layer. Tisseel Fibrin glue will be placed at the base of the defect side, followed by the application of the acellular collagen dermal matrix, ADSCs, and an additional layer of fibrin glue.
Active Comparator: Microfracture Arm
Patients undergo an arthroscopic surgical procedure, microfracture, followed by physical therapy.
Microfracture surgery is the standard of care for articular cartilage lesions. Patients will undergo arthroscopy with standard technique of microfracture preparation, including the creation of vertical, stable defect edges and removal of the calcified cartilage layer. A microfracture awl will then be used to perform the microfracture technique (6mm below the subchondral plate).
- Health Scores on the KOOS Questionnaire [ Time Frame: Completed at baseline, 6 months, 12 months, and 24 months post-operatively. ]The Knee Osteoarthritis Outcome Score (KOOS), a standard outcome questionnaire for the assessment of health-related quality of life, will be completed.
- Activity Level on the Tegner Activity Scale [ Time Frame: Completed at baseline, 6 months, 12 months, and 24 months post-operatively. ]The Tegner Activity scale, a standard outcome questionnaire for assessment of activity levels, will be completed.
- Cartilage Composition Assessment by MRI Scan [ Time Frame: Assessed at baseline, 6 months, 12 months, and 24 months post-operatively. ]Magnetic resonance imaging scans consisting of routine clinical sequences and T2 and T1p quantitative maps will be conducted. T1p and T2 mapping will be used to assess regenerative cartilage composition compared to surrounding normal cartilage, surface integrity, average cartilage thickness, and the percentage to which the defect is filled.
- Functionality Scores on the Lysholm Scale [ Time Frame: Completed at baseline, 6 months, 12 months, and 24 months post-operatively. ]The Lysholm Scale, a standard outcome questionnaire for assessment of knee functionality, will be completed.
- Pain Scores on the Visual Analog Scale (VAS) [ Time Frame: Completed at baseline, 6 months, 12 months, and 24 months post-operatively. ]The Visual Analog Scale, a standard outcome questionnaire for assessment of pain levels, will be completed.
- Health Scores on Veterans-Rand (VR-12) Survey [ Time Frame: Completed at baseline, 6 months, 12 months, and 24 months post-operatively. ]The Veterans-Rand survey, a standard outcome questionnaire for assessment of health and quality of life, will be completed.
