Symptomatic transient patellar ischemia following total knee replacement as detected by scintigraphy. A prospective, randomized, double-blind study comparing the mid-vastus to the medial para-patellar approach.

The most advantageous surgical approach for total knee arthroplasty is not defined. The mid-vastus approach has been suggested to improve patient rehabilitation and prevent patellar devascularization. The following study assessed the changes in patellar vascularity as determined by bone scanning following total knee arthroplasty without lateral release or patellar replacement.

Shoulder girdle neoplasms mimicking frozen shoulder syndrome.

Shoulder pain and immobility comprise a multifactorial disorder apparently affected by pain inhibiting joint motion. As the syndrome is very common, many patients do not undergo detailed imaging studies before treatment. This study compared a series of 7 patients in whom a neoplasm was the underlying cause for the stiff shoulder with a series of 50 patients with primary or secondary frozen shoulder.
