Previous Knee Symptoms, BME and Advanced Age: Crucial for Post-traumatic Knee Osteoarthritis
Physicians should draw extra attention on the development of knee osteoarthritis (OA) as a result of a knee injury, shows a new study. The risk of knee osteoarthritis following trauma may be increased further in the presence of a history of non-traumatic knee symptoms, bone marrow edema (BME) and advanced age.
Main results
- 32% of 1,068 participants developed osteoarthritis of the knee or showed a progression of their knee osteoarthritis showed MRI at the sixth
- Knee osteoarthritis six years following knee trauma was predicted by the presence of non-traumatic knee symptoms, patients’ age and presence of bone marrow edema during initial MRI.
Design of the study
- 1,068 consecutive patients who had seen a general practitioner because of new knee symptoms were assessed at the study entry by an MRI and a questionnaire. In 6 years another MRI and antero-posterior knee radiograph was made.
- Funding: Erasmus MC Rotterdam, Anna Foundation, TRIAS, Zilveren Kruis, Achmea and OZ.
Why is this important?
Physicians, including general practitioners, should pay attention to the development of knee OA as a result of knee trauma.
