Ruptures of the extensor mechanism of the knee are rare, when compared with other knee injuries, and are frequently misdiagnosed. The outcome after surgical repair may be compromised if surgery is delayed. A case of quadriceps tendon rupture that was misdiagnosed for 2 months and a review of the literature are presented. Including extensor mechanism disruption in the differential diagnosis, and careful attention to key physical findings in the examination of all acutely injured knees, will ensure that this important injury is not overlooked.

D008279	Magnetic Resonance Imaging	Non-invasive method of demonstrating internal anatomy based on the principle that atomic nuclei in a strong magnetic field absorb pulses of radiofrequency energy and emit them as radiowaves which can be reconstructed into computerized images. The concept includes proton spin tomographic techniques.
