Geodesic B-score for Improved Assessment of Knee Osteoarthritis

نویسندگان

چکیده

Three-dimensional medical imaging enables detailed understanding of osteoarthritis structural status. However, there remains a vast need for automatic, thus, reader-independent measures that provide reliable assessment subject-specific clinical outcomes. To this end, we derive consistent generalization the recently proposed B-score to Riemannian shape spaces. We further present an algorithmic treatment yielding simple, yet efficient computations allowing analysis large populations with several thousand samples. Our intrinsic formulation exhibits improved discrimination ability over its Euclidean counterpart, which demonstrate predictive validity on assessing risks total knee replacement. This result highlights potential geodesic enable personalized and stratification interventions.

Influence of sitting and prone lying positions on proprioceptive knee assessment score in early knee osteoarthritis.

BACKGROUND Knee proprioception is compromised in knee osteoarthritis. There are several ways of measuring proprioceptive acuity, but there is lack of consensus over the ideal testing position. The study aimed to evaluate the influence of 2 testing positions (sitting versus prone lying) on proprioceptive knee assessment score in patients with early knee osteoarthritis. METHODS The study includ...

A Critical Review of Proximal Fibular Osteotomy for Knee Osteoarthritis

The surgical management of Knee Osteoarthritis (KOA), so far, mainly revolved around arthroscopic procedures,arthroplasty (total: TKA and unicompartmental: UKA) or high tibial osteotomy (HTO). Recently, another minimallyinvasive surgical treatment of proximal fibular osteotomy (PFO) has been proposed for the management of KOA. ThePFO has been found to be useful in the manageme...

Wearable Sensor-Based Rehabilitation Exercise Assessment for Knee Osteoarthritis

Since the knee joint bears the full weight load of the human body and the highest pressure loads while providing flexible movement, it is the body part most vulnerable and susceptible to osteoarthritis. In exercise therapy, the early rehabilitation stages last for approximately six weeks, during which the patient works with the physical therapist several times each week. The patient is afterwar...
