Meniscal Anatomy/Meniscal Injuries

Arthroscopic treatment of meniscal injuries is one of the most common orthopedic surgical procedures. Although our knowledge and understanding of the anatomy) function, and treatment of meniscal pathology has evolved, meniscal tears continue to cause significant symptoms and long-term impairment of the knee.

Osteochondral Dissecans

Osteochondritis dissecans (OCD) is a condition in which a fragment of subchondral bone and its overlying articular cartilage becomes separate from the underlying bone.

Meniscal Anatomy/Biomechanics

The treatment of ACL injuries should be tailored to the individual patient.
