Simultaneous acute myocardial infarction, stroke and critical limb ischaemia: an unusual presentation requiring multidisciplinary approach.

We report the case of a 57-year-old man who presented overnight to a district general hospital as a primary percutaneous coronary intervention alert for an inferior ST elevation myocardial infarction. On presentation to cardiac catheterisation lab, he had ongoing chest pain but began to complain of left-sided limb weakness and pain in his right leg. He was found to have dense hemiparesis on examination with an National Institute of Health Stroke Scale of 8 and an absent right femoral pulse.

Patellar instability and quadriceps avoidance affect walking knee moments.

Purpose: To classify patients with patellofemoral (PF) instability on the basis of their mechanical gait characteristics, and to relate gait deficits to patellofemoral congruence.

Methods: Thirteen patients awaiting patellar stabilisation surgery were recruited for gait analysis and magnetic resonance imaging, MRI assessment of PF congruence. Patients were grouped into two subgroups (P1, P2) based on knee joint moment during stance, and their total support moments (TSMs) during stance were compared against eight healthy Control subjects.
