Blood Flow Restriction Following Hip Arthroscopy

2019-10-09 09:21:41 | BioPortfolio


This study will be a prospective randomized, double-blinded, placebo-controlled trial of patients undergoing primary hip arthroscopy for FAIS and/or labral pathology. All patients who sign the consent form will be enrolled in the study and randomized to one of the two treatment arms. Follow-up will take place at 1-month, 3-months, 6-months, and 1-year.


The investigators propose using standardized strength testing, serial quadriceps measurements, and MRI to assess the efficacy of BFR training in increasing muscle hypertrophy following hip arthroscopy. Investigators will perform a randomized double-blinded placebo-controlled controlled trial of patients undergoing primary hip arthroscopy. Quadriceps strength will be measured with dynamometers at 3, 6, and 12 month time points, with Biodex strength testing at 6 and 12 months, postoperatively. Additionally, standardized circumferential leg measurements to assess quadriceps hypertrophy will be performed at 1, 3, 6 and 12-month time points. Patients will also undergo a hip MRI at 6 months postoperatively to quantify muscle size and appearance about the hip joint. Patient reported outcomes including standard outcomes measures at 3, 6, and 12 months and return to work/sport data will also be collected at standard time points. Patients will also be followed longitudinally for rates of reinjury, return to work, and return to sport.

This study will evaluate the efficacy of BFR therapy in the postoperative period of primary hip arthroscopy to improve muscle hypertrophy during the short-term rehabilitation period. This will be directly measured by strength testing with dynamometers and Biodex testing. Other metrics will include standard validated patient reported outcomes at 3, 6 and 12 month time points including hip disability and osteoarthritis outcome score (HOOS), Harris Hip score (HHS), visual analog scale (VAS) for pain, international hip outcome tool (iHOT-12), and Hip outcome score (HOS), and return to sport questionnaires. Standardized serial circumferential thigh measurements will also be recorded at each visit, in additional to a one time MRI at 6 months postoperatively.

Medical and Biotech [MESH] Definitions

A process in which peripheral blood is exposed in an extracorporeal flow system to photoactivated 8-methoxypsoralen (METHOXSALEN) and ultraviolet light - a procedure known as PUVA THERAPY. Photopheresis is at present a standard therapy for advanced cutaneous T-cell lymphoma; it shows promise in the treatment of autoimmune diseases.

Preliminary cancer therapy (chemotherapy, radiation therapy, hormone/endocrine therapy, immunotherapy, hyperthermia, etc.) that precedes a necessary second modality of treatment.

Measures aimed at providing appropriate supportive and rehabilitative services to minimize morbidity and maximize quality of life after a long-term disease or injury is present.

Damage to the MYOCARDIUM resulting from MYOCARDIAL REPERFUSION (restoration of blood flow to ischemic areas of the HEART.) Reperfusion takes place when there is spontaneous thrombolysis, THROMBOLYTIC THERAPY, collateral flow from other coronary vascular beds, or reversal of vasospasm.

A therapeutic approach, involving chemotherapy, radiation therapy, or surgery, after initial regimens have failed to lead to improvement in a patient's condition. Salvage therapy is most often used for neoplastic diseases.
