About

The study project aims at examining molecular markers in synovial fluid, bone and articular cartilage from osteoarthritic thumb basal joints. The degradation of extracellular matrix (ECM) proteins in thumb basal joints will be evaluated in association to the metabolic profile of the patient, but we also aim to compare the ECM degradation and inflammatory profiles with articular cartilage degradation ECM profile from knee joints with osteoarthritis. A third aim is to evaluate associations between patient-reported hand function, pain, strength and range of thumb motion to analyses of synovial fluid.

Full description

Patients scheduled for trapeziectomy on the basis of thumb basal joint osteoarthritis will be asked to participate. Synovial fluid from the thumb basal joint is aspirated before the joint is opened. The trapezium bone and cartilage is harvested. Blood samples to evaluated lipid profile and glucose intolerance is drawn. Blood pressure and measurements of obesity is taken. Patients are also examined at baseline and 1 year postop with grip strength, pinch strength, range of thumb motion and asked to fill in patient-rated outcome measures; QuickDASH and NRS pain.
