NCT02417987

Brief Summary

The aim of the study is to examine patients with chronic Achilles Tendinopathy (AT) and to compare the effect of high volume injection (HVI) or autologous conditioned plasma (ACP) in combination with eccentric training to placebo treatment (sham treatment combined with eccentric exercises). Healthy males with AT will be randomly assigned to either 1) HVI (50 mls;10 mls 0.5% bupivacaine hydrochloride and 20 mg of Depomedrol followed by 40 mls saline), 2) ACP (\~ 4 mls) or 3) Placebo (Plc) treatment. All subjects will perform a 12-wk eccentric training program and examinations will be done at baseline (before treatment) with follow-ups after 6 weeks, 12 weeks and again after 24 weeks prior to baseline to see any possible changes and differences between groups (HVI, ACP and Plc)

Outcome Measures

Primary Outcomes (1)

  • VISA-A score

    See the changes in VISA-A score over time due to the effect of treatment between groups (HVI, ACP and Plc)

    Baseline, 6 weeks, 12 weeks and 24 weeks

Secondary Outcomes (2)

  • VAS score

    Baseline, 6 weeks, 12 weeks and 24 weeks

  • Ultrasound tendon thickness and doppler activity

    Baseline, 6 weeks, 12 weeks and 24 weeks

Other Outcomes (1)

  • Muscle function performance test (total workload)

    Baseline, 6 weeks, 12 weeks and 24 weeks

Study Arms (3)

High Volume injection

ACTIVE COMPARATOR

A total volume of 50 ml: * 10 mls 0.5% bupivacaine hydrochloride and * 20 mg of Depomedrol (hydrocortisone) * 40 mls saline (NaCl) HVI is injected one time at baseline and thereafter the group received sham treatment at 2 weeks, 4 weeks and after 6 weeks.

Other: PlaceboBiological: Autologous conditioned plasma (ACP)

Autologous conditioned plasma (ACP)

ACTIVE COMPARATOR

Whole blood was drawn from the patients using arthrex system (total of 10 mls whole blood). After that the whole blood is spined for 5 minutes and ACP with platelets and growth factors is separated from the red and white blood cells (4 mls). The ACP is injected 4 times (at baseline, 2 weeks, 4 weeks and after 6 weeks)

Other: PlaceboDrug: High Volume injection

Placebo

SHAM COMPARATOR

A few drops of saline is injected in the soft tissue away from the tendon.

Drug: High Volume injectionBiological: Autologous conditioned plasma (ACP)

Interventions
