Osteochondritis Dissecans of Knee Prospective Cohort

Osteochondritis Dissecans

The Cohort is a multi-site prospective data collection study that will enroll any patient with diagnosis of knee OCD (confirmed by a standard of care x-ray or MRI). Patients will be followed for up to the next 50 years of their lives to study courses of care, disease progression, treatment/surgical options/results, and specific sports-related outcomes in athletic patients. Subjects will complete quality of life surveys as part of the Cohort. Course of care will not be affected.

Patients will be recruited and consented at the visit in which their eligibility is determined. Once a patient is eligible and provides informed consent, he or she will be in the study for up to 50 years, or until his or her OCD lesion is healed successfully. At the initial visit, a subject will complete a basic medical history form, and three questionnaires: the IKDC Subjective questionnaire (ages over 18) or the PEDI-IKDC Subjective questionnaire (ages under 18); the KOOS questionnaire; and the Marx Activity Scale (adult) or Pedi-FABS Scale (pediatric). Patients will then continue with their normal course of care as determined by their surgeon and care team. Mandatory surveys (same as above) will be collected from patients at 2 years, 5 years, 10 years, and 25 years. Patients who cannot return to clinic will have the option to complete the assessments and return in pre-stamped and addressed return envelopes provided by the clinical site the subject is a patient at. Any other follow-up visits between these time intervals will also be options for patients to complete these assessments, however patients will not complete them any closer than intervals 12 weeks apart in order to prevent redundancy. Additionally, at the initial visit, the surgeon will complete a routine patient history and physical exam, which will be collected. Any surgical procedures or physical therapy a patient undergoes for treatment of his or her OCD lesion will also be documented and collected. At follow-up visits, surgeons will complete their own physical exam follow-up assessment forms, which will be collected.
