Web-based Survey of Protocols for Microfracture Surgery of Chondral and Osteochondral Defects of the Knee

Nth Dimensions

Introduction: Microfracture surgery produces small fractures in subchondral bone to release marrow-based growth factors and progenitor cells that proliferate and differentiate into cells that promote healing of chondral lesions, and is effective for arthroscopic treatment of full-thickness chondral lesions. The purpose of this study is to assess orthopedic surgeon’s preferences for the treatment of chondral and osteochondral defects of the knee using microfracture surgery

Methods: A web-based survey of 34 questions consisting of surgical techniques, postoperative protocols and rehabilitation protocols was developed using the survey tool Qualtrics, and administered to members of the International Cartilage Repair Society to assess current trends in microfracture surgery. 

Results: Results are pending but we hope to receive at least a 50 percent response rate from orthopedic surgeons. We will compare indications for surgery, instruments, agents and techniques used during microfracture surgery, and postoperative rehabilitation protocols. We anticipate that there will be variability among orthopedic surgeon’s protocols, particularly when comparing non-sports medicine orthopedic surgeons to sports medicine orthopedic surgeons.  

Conclusion: Despite microfracture surgery being developed in the 1980’s and now being a first-line treatment for chondral defects, currently there are no set clear universal guidelines or recommendations for the use of microfracture surgery on chondral and osteochondral defects of the knee. This data may be used to further facilitate the establishment of a consensus of best practices in the use of microfracture surgery.
