Primary Outcome Measures:
  • Change from Baseline in VISA-A score at 12 weeks [ Time Frame: 12 weeks ]
    Functional impairment of the Achilles tendon is measured using VISA-A score. Score of patient-related outcome measure: Achilles tendon: VISA-A [0=worse, 100=perfect] derived from eight validated questions on pain and function during activities of daily living


Secondary Outcome Measures:
  • Pain level at rest [VAS 0-10] [ Time Frame: 0, 6, 12 weeks ]
  • Pain level at exertion [VAS 0-10] [ Time Frame: 0, 6, 12weeks ]
  • Achilles transverse thickness by ultrasound [ Time Frame: 0, 6, 12 weeks ]
    Ultrasound evaluation of Achilles tendon. Maximum thickness will be recorded in the midportion of the affected Achilles tendon

  • SF-36 v2 quality of life survey [ Time Frame: 0, 12 weeks ]
  • Patient satisfaction [ Time Frame: 6, 12 weeks ]
    Patient satisfaction will be evaluated using a subjective questionnaire.

  Eligibility

Ages Eligible for Study:   18 Years to 70 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Patients suffering from a gradually evolving painful condition in the Achilles tendon located at the midportion for at least 3 months (Diagnosis based on clinical examination showing a painful thickening of the Achilles tendon located at a level of 2 to 6cm above the tendon insertion, and confirmed by ultrasonography: local thickening of the tendon, irregular tendon structure with hypoechoic areas and irregular fiber orientation).
  • Men and non-pregnant women aged 18-70 years
  • Be informed of the nature of the study and provide written informed consent.

Exclusion Criteria:

  • Clinical suspicion of insertional disorders (pain at the site of the insertion of the Achilles tendon on the calcaneum)
  • Clinical suspicion of an Achilles tendon rupture (Thompson test abnormal and palpable "gap")
  • Clinical suspicion of plantar flexor tenosynovitis (posteromedial pain when the toes are plantar flexed against resistance)
  • Clinical suspicion of n.suralis pathology (sensitive disorder in the area of the sural nerve)
  • Clinical suspicion of peroneal subluxation
  • Suspicion of internal disorders: spondylarthropathy, gout, hyperlipidemia, Rheumatoid Arthritis and sarcoidosis.
  • Condition that prevents the patients from executing an active exercise programme
  • Patient has already performed eccentric exercises, according to the schedule of Alfredson et al (12 weeks)
  • Patient has already received an injection of PRP for this injury
  • Patient does not wish, for whatever reason, to undergo one of the two treatments
  • Known presence of a pregnancy
  • Condition of the Achilles tendon caused by medications (arising in relation to moment of intake), such as quinolones and statins
