Brief Summary:

The purpose of this study is to compare the clinical and functional outcomes of patients with mild to moderate arthroscopically confirmed osteoarthritis between the following two groups:

  1. Partial fat pad harvest with Adipose-Derived Stem Cell (ADSC) transplantation with standard arthroscopic treatment consisting of: partial meniscectomy, cartilage stabilization, loose body removal and selective synovectomy.
  2. Standard arthroscopic treatment (above) with out cell transplant.

Condition or disease Intervention/treatment Phase
Knee Osteoarthritis Procedure: Arthroscopic debridement with stem cell transplantation Procedure: Arthroscopic debridement only Not Applicable

Detailed Description:

Adipose-derived stem cells (ADSC) may be beneficial to patients with OA because they may differentiate into chondrocytes, promote endogenous tissue repair, and have potent anti-inflammatory properties.

Early studies show promising clinical results using ADSCs to treat patients with osteoarthritis, but no clinical trials have been completed comparing cellular therapy to standard arthroscopic treatment.

The investigators aim to determine whether ADSC transplantation as adjuvant therapy in patients with arthroscopic findings of mild to moderate arthritis will result in improved clinical outcomes scores at one and two-year follow-up compared to standard arthroscopic treatment.
