Preoperative Exercise in Patients Undergoing Total Hip or Knee Replacement - Full Text View

Purpose

This study is conducted in the Community Hospital in Svendborg (OUH Svendborg Sygehus) in collaboration with University of Southern Denmark and Odense University Hospital.

The overall purpose of this study is to evaluate the effects of preoperatively delivered neuromuscular exercise on self perceived physical function, pain and Quality of Life in patients undergoing total hip or knee replacement. Secondary area of interest is physical performance, muscle function, and level of physical activity.

The project will be conducted in two phases:

A pilot project focusing on the logistics of the upcoming randomized controlled trial (RCT) and determination of test-retest reliability of specific muscle strength variables for the patients of interest
A randomized and controlled trial where the intervention is preoperative neuromuscular exercise and the controls receive standard instructions.

Primary Outcome Measures:

Change in self reported physical function. Assessed with KOOS/HOOS questionnaire subscale ADL Function [ Time Frame: 3 month postoperative (primary endpoint) ] [ Designated as safety issue: No ]
Further assessments: baseline, preoperative, 6 weeks postoperative and 1-year follow up

Secondary Outcome Measures:

Self reported pain. Assessed with KOOS and HOOS subscale on pain. [ Time Frame: baseline, one week preop., 3 month postop.(primary endpoint) and a 1 year follow up ] [ Designated as safety issue: No ]
Self reported quality of life (Qol). Assessed with KOOS and HOOS sub scale quality of life [ Time Frame: baseline, one week preop., 3 month postop.(primary endpoint) and a 1 year follow up ] [ Designated as safety issue: No ]
Self reported quality of life. Assessed with EQ5D questionnaire [ Time Frame: baseline, one week preop., 3 month postop.(primary endpoint) and a 1 year follow up ] [ Designated as safety issue: No ]
Observed physical function. Assessed with performance measures: 20 meter walk, 5 chair stands timed and one leg knee bendings/30 sec [ Time Frame: baseline, one week preop. and 3 month postop. ] [ Designated as safety issue: No ]
Muscle strength estimated as average muscle power for muscles of the hip and knee [ Time Frame: baseline, 1 week preop. and 3 month postop ] [ Designated as safety issue: No ]
