Research Study to Compare the Addition of Topaz Micro Debridement to the Standard of Care Surgery

This study has been completed.

Compare the surgical use of Topaz with the Standard Of Care in the treatment of Greater Trochanteric Pain Syndrome (a type of hip pain). The hypothesis is that there is a difference between the two treatment groups.

Condition Intervention
Greater Trochanteric Pain Syndrome Hip Pain Chronic Device: Topaz Procedure: Iliotibial band release and trochanteric bursectomy

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Outcomes Assessor)
Primary Purpose: Health Services Research
Official Title: A Randomised, Controlled, Double-blind Clinical Investigation on the Efficacy and Safety of Radiofrequency Micro Debridement, Topaz, in Recalcitrant Greater Trochanteric Pain Syndrome (GTPS) vs. Standard of Care

Further study details as provided by Smith & Nephew, Inc.:

Primary Outcome Measures:
  • Modified Harris Hip Score [ Time Frame: 6 months ]
    This is a patient questionnaire used to evaluate hip function following surgery.

Secondary Outcome Measures:
  • The Western Ontario and McMaster Universities Arthritis Index [ Time Frame: 1 year ]
    This is a patient questionnaire used to evaluate rheumatic symptoms, stiffness, pain and how it affects the ability to function.

  • Visual Analogue Scale [ Time Frame: 1 year ]
    This is a patient questionnaire designed to evaluate pain.

  • SF-12 Health Survey [ Time Frame: 1 year ]
    This is a patient questionnaire measuring health-related quality of life.

  • Duration of surgery between two treatment groups [ Time Frame: 1 day ]
    The total length (time) of surgery will be compared between the two groups.

  • Ultrasound findings [ Time Frame: 1 year ]
  • Adverse events [ Time Frame: 1 year ]

Enrollment: 66
Study Start Date: April 2012
Study Completion Date: October 2016
Primary Completion Date: October 2016 (Final data collection date for primary outcome measure)
