Cassandra A. Lee

Philosophy of Care

I believe in working together as partners with my patients. My job is to educate my patients about their sports injuries and to help guide them through their rehabilitation process, whether it be for operative or nonoperative management.

Clinical Interests

Dr. Lee's clinical interests relate to the diagnosis and management of patients who have sustained sports-related orthopaedic injuries, with emphasis on the knee and shoulder problems. 

Her surgical specialties include ligament reconstruction, cartilage preservation (such as osteochondral allograft and autologous chondrocyte implantation), meniscal transplantation and multiligamentous knee reconstruction. 

Dr. Lee also specialize in arthroscopic shoulder procedures such as instability and rotator cuff repairs, as well as open-shoulder reconstruction procedures.

Dr. Lee currently serves as an official team physician for the Sacramento Republic FC professional men's soccer team.

Research/Academic Interests

Dr. Lee's research interests include the study of cartilage regeneration and ligament biology, and how they translate to clinical outcomes.
