Acute and chronic effects of early progressive resistance training on knee pain and knee joint effusion after unicompartmental knee arthroplasty.

To investigate if progressive resistance training initiated one week after unicompartment knee arthroplasty affect knee pain and knee joint effusion. Data from the progressive resistance training intervention group of a previous randomized control trail study was analysed. Knee pain was measured using a visual analogue scale, and knee circumference was used as an indication of knee joint effusion.

High-Intensity Resistance Training Does Not Produce Immediate Ultrasonographic Changes in Muscle Tendons.

Background: Chronic overload injuries to tendons can be visualized using ultrasonography, with characteristics such as tendon thickening and darkening.

Purpose: To investigate whether these characteristics are evident in the patellar and Achilles tendons immediately after 1 session of high-intensity resistance training.

Study Design: Controlled laboratory study.
