Monitoring of Acute Knee Injuries to Understand Osteoarthritis Development
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.

Using magnetic resonance imaging (MRI), laboratory analyses and patient reported outcomes, the overall aim of this study is to investigate structural injuries and biochemical alterations in the acutely injured knee and to relate these findings to clinical outcomes at various time points.
Choosing to participate in a study is an important personal decision. Talk with your doctor and family members or friends about deciding to join a study.

Ages Eligible for Study:
12 Years to 40 Years (Child, Adult)
Sexes Eligible for Study:
Accepts Healthy Volunteers:
We will recruit approximately 150 patients annually over 3-4 years with the goal of including at least:
200 knees with isolated or combined ACL injuries
50 isolated meniscus tears
50 primary patellar dislocations
50 contusions without ligamentous, cartilage or meniscus injury.
Patients will be recruited using two different strategies:
Those seeking medical care at the orthopedic emergency room (ER) at Helsingborg hospital
Those referred to the orthopedic outpatient health care unit of Helsingborg hospital due to an acute knee injury by their primary health care unit will be scheduled for a clinical visit for baseline assessment (visit 1) within four weeks from their injury. To facilitate recruitment, primary care units in the local area of Helsingborg will be offered an opportunity to refer all patients with rotational knee trauma and effusion directly to the orthopedic outpatient care unit.
Age 12-40 years at inclusion (inclusion of patients younger than 18 will require parental approval)
A history of knee injury not more than 4 weeks prior to inclusion
Agreement and informed consent to participate in the study
Any MRI contra-indications (such as extreme obesity, metal implants, claustrophobia etc.)
A history of deep vein thrombosis (DVT) or a disorder of the coagulative system
General disease that effects physical function or systemic medication/abuse of steroids
Any other condition or treatment interfering with the completion or assessment of the trial.
