Osteoarthritis (OA) of the knee is a very common chronic joint disorder associated pain and disability. As no cure exists, management aims to reduce pain, improve function, and enhance quality of life. The recommended hierarchy of management should consist of exercise in first line, then the add-on of drugs if necessary, and ultimately, if necessary, surgery.
The effect size of exercise therapy is of the same magnitude as most pharmacological treatments but is often without adverse effects. Local pharmacological treatment of the afflicted knee joint is recommended by means of intra-articular injections of corticosteroids, which is considered as a standard medical treatment of knee OA and are included in established guidelines for management of knee OA. While the two treatment approaches have been investigated separately in numerous clinical trials, the efficacy of a combined pharmacological and non-pharmacological approach is not known, despite the high rank of such combined treatment approach on the recommended hierarchy of management.
The purpose of this study is to assess the effects of exercise therapy in combination with intra-articular corticosteroid injections on patient reported pain and function in patients with knee OA.
The hypothesis is that the combined treatment approach (exercise therapy preceded by intra-articular injection of corticosteroid) enhances the clinical outcome compared to exercise therapy preceded by a placebo injection.

| Intraarticular saline | Drug | 1 ml isotonic saline mixed with 4 ml Lidocain (10 mg/ml) without adrenalin. Injections are done ultrasound guided |
|
| Exercise therapy | Other | The exercise is commenced 2 weeks after injection. The exercise includes a 10 minute warm up phase (ergometer bicycling) followed by strengthening and coordination exercises focusing on trunk, hip and knees. In case of pain or symptom exacerbation, a rescue exercise program is administered, excluding weight bearing activities. |

Self-reported knee symptoms, knee related function, quality of life and, function during sports and recreation assessed by the pain subdomain in the Knee Injury and Osteoarthritis Outcome Score (KOOS) questionnaire
| Change from baseline to week 2, 14, and 26 |
| Functional pain test | Knee OA pain is associated with movement of the afflicted knee. Therefore we assess pain intensity and movement tolerance during repeated squatting. The test has 3 outcomes: 1) The number of pain free squatting movements that can be done in 30 seconds; 2) the number of painful squatting movements that can be done in 30 seconds; and 3) the average pain intensity during the squatting movements assessed on a 0-10 numeric rating scale. | Change from baseline to week 14, and 26 |
| Knee Muscle strength | Assessed by an isokinetic dynamometer | Change from baseline to week 14, and 26 |
| 6 minute walk distance | The distance covered during 6 minutes of fast walking | Change from baseline to week 14, and 26 |
| Systemic markers of inflammation in blood | Blood sample | Change from baseline to week 14, and 26 |
| MRI based inflammation | To assess the severity and extent of local inflammation in the knee and surrounding tissues magnetic resonance imaging (MRI) are done before and after intravenous injection of a Gadolinium contrast agent. Contrast agents are only administered to participants with normal kidney function assessed from a standard blood sample | Change from baseline to week 14, and 26 |
