文摘

To evaluate for development of Pellegrini–Stieda (PS)-type ossification following injury to the posterior attachment of the medial patellofemoral ligament (MPFL).

Materials and methods

This retrospective study evaluated 27 patients with acute knee injury with initial radiographs, magnetic resonance imaging within 1 week of injury, and follow-up radiographs assessing for development of PS.

Results

Of the 27 patients who developed PS ossification, 7 patients (25.9%) had isolated MPFL injury with the ossification slightly more proximal than the traditional PS.

Conclusion

Isolated injury to the posterior MPFL also leads to PS ossification, which is slightly superior in location to the traditional PS.
