Acute Traumatic Swan Neck Deformity: A Case Report of the Oblique Retinacular Ligament Lesion.

Swan neck deformity (SND) can be the manifestation of an acute trauma. We present a case report of a young basketball player with an acute traumatic SND determined by the single ulnar oblique retinacular ligament rupture. The patient caught a ball directly upon the tip of his right's hand middle finger into extension.

A new patellofemoral scoring system for total knee arthroplasty.

Patellofemoral complications after total knee arthroplasty (TKA) can result in substantial dissatisfaction with the procedure for some patients. In assessing outcomes of TKA, however, there is often a discrepancy between patellofemoral symptoms and the results obtained by conventional scoring and radiographic analysis. We asked whether a new scoring system and weightbearing radiographic view would more accurately represent patellofemoral kinematics and explain related complications.
