Inter-Rater Reliability of Clinical Testing for Laxity After Knee Arthroplasty.

Background: The clinical examination for laxity has been considered a mainstay in evaluation of the painful knee arthroplasty, especially for the diagnosis of instability. More than 10 mm of anterior-posterior (AP) translation in flexion has been described as important in the diagnosis of flexion instability. The inter-observer reliability of varus/valgus and AP laxity testing has not been tested.

Comparison of Race Time-Differences Between and Within Para and Able-Bodied Cross-Country Skiers.

Purpose: To compare differences in race time (i.e., the average percent difference in race time for each skier compared to the winner, RT) between female and male Para and able-bodied (AB) skiers, and to examine whether RT change across seasons.

Effects of a corrective heel lift with an orthopaedic walking boot on joint mechanics and symmetry during gait.

Background: Orthopaedic walking boots are commonly prescribed following injury and surgery. The boot creates a leg length discrepancy which is thought to affect limb symmetry and gait mechanics. This study aimed to examine the effects of a corrective heel lift for the contralateral limb on the mechanics and symmetry of walking with an orthopaedic walking boot.
