Mobility metrics in individuals with and without an indication for knee arthroplasty: An explorative analysis.

Background: It is conceivable that candidates for total knee arthroplasty due to knee osteoarthritis have poorer walking ability than people who do not have an indication for total knee arthroplasty. This study explored the discriminative ability of mobility metrics between individuals with and without an indication for total knee arthroplasty.

Methods: Mobility metrics were collected with inertial sensors on the same day as the consultation with the orthopedic surgeon in which the decision for total knee arthroplasty eligibility was made.

Implant stability and clinical performance of a bicruciate-retaining total knee arthroplasty: A radiostereometric analysis up to 7.5 years follow-up.

Background: A previous randomized controlled trial showed higher tibial migration and more device-related complications in bicruciate-retaining compared to cruciate-retaining total knee arthroplasty, raising concerns about long-term implant stability and prompting this follow-up study to assess migration patterns and clinical outcomes up to 7.5 years postoperatively.

Methods: In this follow-up study, the bicruciate-retaining group from an initial single-centre randomized controlled trial was monitored at 5 and 7.

Real-world gait and turning in individuals scheduled for total knee arthroplasty.

Background: Improving mobility - specifically walking - is an important treatment goal of total knee arthroplasty. Objective indicators for mobility, however, are lacking in clinical evaluations. This study aimed to compare real-world gait and turning between individuals scheduled for total knee arthroplasty and healthy controls, using continuous monitoring with inertial measurement units.

Individuals with knee osteoarthritis show few limitations in balance recovery responses after moderate gait perturbations.

Background: Knee osteoarthritis causes structural joint damage. The resultant symptoms can impair the ability to recover from unexpected gait perturbations. This study compared balance recovery responses to moderate gait perturbations between individuals with knee osteoarthritis and healthy individuals.
