Magnetic resonance imaging, knee arthroscopy, and clinical decision making: a descriptive study of five surgeons.

Objectives: A randomized controlled trial (RCT) showed magnetic resonance imaging for patients waiting for knee arthroscopy did not reduce the number of arthroscopies. Our study aimed to identify decisions made by orthopedic surgeons about whether patients on a waiting list should proceed to arthroscopy, and to describe surgeons' decisions.

Methods: Five surgeons were asked to Think Aloud (TA) as they made their decisions for twelve patients from the original RCT.

Sub-vastus approach is more effective than a medial parapatellar approach in primary total knee arthroplasty: a randomized controlled trial.

In a prospective single-centre longitudinal randomized controlled trial 116 patients were allocated to the sub-vastus approach, and 115 to the medial parapatellar approach. At one week follow-up, compared to baseline, range of motion, Knee Society (KS) global, KS knee, and KS pain scores were significantly better in the sub-vastus group. At the one year follow-up, WOMAC global and pain scores, SF36 physical function and role-physical scores, and EuroQol utility and pain score were significantly better in the sub-vastus group.
