Study of Cartilage Relaxometry and Physical Activity in Osteoarthritis

Not Applicable

Withdrawn

• Conditions: Osteoarthritis
• Interventions: Other: Strength Training; Other: Aerobic Exercise

• Registration Number: NCT01797679
• Lead Sponsor: University Hospital, Akershus

Brief Summary

This study is the radiological component of an earlier registered trial under the title: Efficacy of Exercise on Physical Function and Cartilage Health in Patients With Knee Osteoarthritis. The main purpose in this component of the study is to evaluate the efficacy of aerobic exercise and strength training on the T2 and T1 rho relaxation times of the articular cartilage. It has been proven that exercise can improve function and reduce the need for analgesics in patients with osteoarthritis. With this study, we wish to investigate if different kinds of exercise can cause measurable improvements in T2 and T1 rho relaxation times of the articular cartilage, and also if this improvements are transient or permanent.

Arm && Interventions

Group	Intervention	Description
Strength Training	Strength Training	The strength group include progressive strength training and neuromuscular exercises. The inclusion will be performed 2-3 times a week for 12 weeks. Intervention: Other: Strength training
Aerobic exercise	Aerobic Exercise	The aerobic exercise group will cycle on an ergometer bicycle 2-3 times a week for 12 weeks on moderate loading. The loading will be controlled by a heart rate monitor and is defined as 85% of maximal heart rate.

Primary Outcome Measures

Name	Time	Method
Qualitative Cartilage Morphology Assessment	One year	Indirect cartilage morphology will by assessed by X-ray Direct cartilage morphology will be assessed by MRI morphometry The biochemical composition of the cartilage will be assessed by relaxometry (T2 and T1 rho relaxation times)

Secondary Outcome Measures

Name	Time	Method
Semiquantitative Cartilage Assessment	One year	Using semiquantitative techniques, the clinical manifestations of osteoarthritis assessed by MRI such as: cartilage lesions and bone marrow lesions will be assessed and quantified by MRI.
