We will investigate the effect of peritendinous corticosteroid injections, eccentric training and heavy resistance training in male patellar tendinopathy patients. The purpose is to compare the clinical effect of these three treatments in a randomised controlled trial. Also we wish to investigate the treatment mechanisms responsible for the effectiveness of the three treatments.

Enrollment: 39
Study Start Date: March 2006
Study Completion Date: November 2007
Arms Assigned Interventions
Active Comparator: CORT
Peritendinous corticosteroid injections at 0 and 4 weeks. 12 weeks total
Procedure: peritendinous corticosteroid injections
1 ml of40mg/ml methylprednisolone acetate at 0 and 4 weeks. 2 week observational
Experimental: ECC
12 weeks of eccentric unilateral decline squats
Procedure: eccentric decline squat training
eccentric decline unilateral squats performed twice daily. for 12 weeks
Experimental: HSR
Heavy slow resistance training. 3/week. 12 weeks
Procedure: heavy slow resistance training
Heavy slow resistance training for knee extensors. 3/week. total of 12 weeks

Detailed Description:

3 interventions groups as described above (n=13 in each group) 12 weeks intervention period. Clinical assessments before and after intervention: VAS, VISA, Tendon thickness, Doppler us activity.

Before and after intervention tendon biopsies will be taken and analyzed for crosslinks and fibril diameter. Also tendon mechanical properties will be measured. Tendon and muscle structural properties will be measured with MRI.

Treatment satisfaction will be stated after intervention period.
