Hindfoot Alignment in Total Knee Replacement
OsteoarthritisWhen carrying out a knee replacement operation one of the goals is to correct any deformity of the leg (bowlegged or knock kneed). The ideal alignment is the mechanical axis, which is a line from the centre of the hip joint to the centre of the ankle. This line indicates how the weight of the body is transmitted to the ground via the leg. Often the planning for a knee replacement uses an Xray which shows the hip, knee and ankle (HKA Xray) so that the mechanical axis can be drawn on. However, the weight of the body goes to the ground from the ankle through the heel. There have been some reports recently suggesting that deformities in the heel can influence the overall leg alignment after a knee replacement; this may affect how successful the surgery is, or how long the knee replacement will last. Therefore it may make sense to take the alignment of the leg including the heel in planning for a knee replacement. The conventional practice to assess the alignment of the heel is a hindfoot alignment view (HAV) Xray. This only shows the foot. Having two separate Xrays means more radiation exposure and makes linking the two alignments very difficult. We propose a single novel Xray extending the HKA Xray to shows hip, knee, ankle and heel (HKAH Xray) enabling measurement of both alignments. This study is to validate the hindfoot alignment seen on the novel Xray with the standard HAV. Patients undergoing a knee replacement will be enrolled. Patients will have both a HKAH and HAV Xray before surgery. The alignment of the heel measured on the HKAH Xray will be compared with the standard HAV to see if it is accurate.
Stated-Preferences in Knee Arthroplasty
ArthritisKnee Osteoarthritis1 moreThe primary objectives of this study are to apply best-practice stated-preference methods to quantify patient preferences for benefit-risk tradeoffs associated with arthroplasty treatment options for end-stage osteoarthritis of the knee. Duke will develop and administer stated-preference surveys to adult patients (Ages 40-80) with knee pain to collect preference data, estimate the relative importance of treatment features and outcomes, and estimate maximum acceptable risks for given benefits and minimum acceptable benefits for given harms. This study proposal describes plans for the patient stated-preference survey.
Can 3D Kinematic Parameters Assess the Symptomatic and Functional Severity of KOA?
Osteoarthritis,KneeThere is little study focusing on kinematic parameters in the assessment of the symptomatic and functional severity of knee osteoarthritis (KOA). The purpose of this study is to evaluate the correlations between kinematic parameters and the severity of symptoms and functions in patients with KOA.

Osteoarthritis Relationships and Tobacco " Ancillary Study Khoala "
OsteoarthrosisThe role of tobacco in osteoarthritis remains controversial. The Khoala cohort is the first multicenter French cohort of subjects with knee and / or hip osteoarthritis prevalent . It guarantees its methodology great representativeness and therefore an interesting material for the study of risk factors in the population. In addition, it should have little here Radiographs of hands for all its patients. It therefore has the opportunity to study a possible relationship between tobacco and hip osteoarthritis , knee and hand but also to study the relationship between tobacco and structural evolution of hip osteoarthritis and / or symptomatic knee.

Subject Insights to Understand the Hand Osteoarthritis (HOA)
OsteoarthritisOsteoarthritis (OA) is a degenerative joint disease which causes joints to become painful and stiff. HOA is the second most common form of OA and is characterized by stiffness, joint pain and inflammation and tenderness in the knuckles or around the waist. This cross-sectional, qualitative interview study aims to explore the experience of erosive HOA as well as explore the content validity of the Michigan Hand Outcomes Questionnaire (MHQ) by conducting semi-structured combined concept elicitation (CE) and cognitive debriefing (CD) telephone interviews and real-time data capture. The conceptual model developed from this data will be used to support the development of GSK3196165, a human monoclonal antibody target for the treatment of HOA. The CE interviews (45 minutes duration) will explore the experience of subjects suffering with HOA and will collect information about symptoms, health related quality of life (HRQoL), treatment experience and the language used by subjects to describe them whereas the CD interviews (45 minutes duration) will assess the content validity of the MHQ. The real-time disease experience of subjects will be captured by the real-time data capture app-based activity over a period of 7 days. Approximately 30 subjects from the United States (US) of which 15 subjects will be erosive HOA and rest 15 will be non-erosive HOA.
Gait Asymmetry Assessed Using Portable Gait Analysis System
Ankle OsteoarthritisKnee Osteoarthritis3 moreTo date, detailed analysis of movement patterns in orthopaedic conditions are mainly performed in research projects. Because these tests are time consuming, they are not feasible in clinical routine or in standard examinations. Novel technologies allow capturing detailed movement patters within a few minutes. The aim of this regional study is to compare aspects of movement tasks measured using a mobile gait analysis system to those measured using laboratory based systems and to determine aspects of gait patterns relevant for different orthopaedic conditions. Moreover, the researchers will investigate if these relevant aspects can be altered using surgical treatment or manual therapy.
