A case-series review was performed on five collegiate athletes with osteochondral lesions of the knee at California State University, Northridge (CSUN). All subjects received surgical intervention to treat the defect. The surgeries performed were either an Osteoarticular Transfer System (OATS) procedure and/or a Microfracturing procedure. Subjects were treated post-operatively by the CSUN team physical therapist and/or athletic trainers at CSUN. This paper seeks to provide information about osteochondral defects of the knee, the surgical interventions, and a protocol for post-operative treatment and rehabilitation of such injuries.

Inclusion Criteria:

• Student athlete at CSUN
• Diagnosed with Osteochondral dissecans (OCD)
• Underwent surgical procedure to treat OCD
• Treated postoperatively by the team physical therapist and/or athletic trainers at CSUN.

Exclusion Criteria:

- No concurrent ligamentous injures to the knee during the time of subject participation in the study

The subjects were recruited from a population of student athletes at California State University, Northridge. These athletes were being treated by the Physical Therapy and/or Athletic Training Departments for Osteochondral Defect of the knee.
