- Original description
Osteoarthritis (OA) stands out as the most prevalent joint disease. It manifests as a progressive degradation of articular cartilage, new bone growth and often synovial tissue proliferation, resulting in pain and compromised joint functionality, ultimately leading to disability. Misalignment of the lower limb (varus or valgus knees) are recognised as a risk factor for osteoarthritis onset and progression. High tibial osteotomy (HTO) is a surgical technique that allows to shift the load from the affected area to other areas with intact cartilage. Similarly to HTO, braces realign the lower limb, without the need for surgical intervention. These corrective treatments are recommended for the youngest group of patients as it allows them to stay active, as opposed to Total Knee Replacement (TKR). Until today, the effects of braces and HTO on the subchondral bone microstructure and cartilage are not well understood. Investigating these aspects to better understand treatment failures is becoming more and more crucial because global prevalence of knee OA is expected to increase with the ageing of populations.Read full original descriptionShow less
Altered Joint Mechanics and Biological Response in Osteoarthritic Knees. A Study in Patients Undergoing Corrective Treatment for Knee Misalignment.
Osteoarthritis (OA) stands out as the most prevalent joint disease. It manifests as a progressive degradation of articular cartilage, new bone growth and often synovial tissue proliferation, resulting in pain and compromised joint functionality, ultimately leading to disability. Misalignment of the lower limb (varus or valgus knees) are recognised as a risk factor for osteoarthritis onset and progression. High tibial osteotomy (HTO) is a surgical technique that allows to shift the load from the affected area to other areas with intact cartilage. Similarly to HTO, braces realign the lower limb, without the need for surgical intervention. These corrective treatments are recommended for the youngest group of patients as it allows them to stay active, as opposed to Total Knee Replacement (TKR). Until today, the effects of braces and HTO on the subchondral bone microstructure and cartilage are not well understood. Investigating these aspects to better understand treatment failures is becoming more and more crucial because global prevalence of knee OA is expected to increase with the ageing of populations.
Inclusion: Voluntary written informed consent of the participant or their legally authorized representative has been obtained prior to any screening procedures; Chronic symptoms of (early) knee OA; Misalignment of the lower limb and scheduled for HTO surgery (regardless of the HTO technique used (lateral or medial, closing or opening wedge)) or brace treatment; Follow-up at UZ Leuven.
Exclusion: Acute OA symptoms onset (previous knee injury); Impaired vision or neurological condition that affect coordination and balance; Age <18 (no minors will be included in the study); Pregnant women; MRI checklist incomplete or failed; BMI > 30.
