Clinical Trial Summary

Femoroacetabular impingement syndrome (FAIS) is a condition caused by an abnormal bone structure that causes the bones on either side of the hip joint to impinge on each other during certain movements, thus causing pain. This condition can be surgically treated with hip arthroscopy. For patients undergoing hip arthroscopy, there are currently two protocols related to how they may bear their weight after surgery: 1) Delayed Weightbearing: Patients use crutches and put very little weight on the surgical side. After 6 weeks, they are able to bear weight, 2) Immediate Weightbearing: Patients bear weight on the affected side, as tolerated, immediately after surgery with crutches for additional support. They are then permitted to stop using the crutches in the weeks after surgery as they feel comfortable and are stable on the operative leg.

The purpose of this study is to determine whether immediate or delayed weightbearing protocols following hip arthroscopy impact patient outcomes and complication rates. Participants will be randomly allocated into one of the two aforementioned groups, and followed up for 2 years to assess function and patient-reported outcomes.

Description:

Hip arthroscopy is used in the surgical treatment of femoroacetabular impingement syndrome (FAIS). There remains debate as to whether patients should be restricted to touch weightbearing post-operatively to prevent complications and improve clinical outcomes. This study aims to assess whether early weightbearing will produce non-inferior patient reported outcomes compared to protected touch weightbearing at 1 year post-operatively. We hypothesize that patients who are allowed to bear weight immediately after surgery will have non-inferior outcomes in comparison to those allowed to bear weight at 6 weeks post-operatively.

The FASTHIP trial is a multi-center, non-inferiority randomized controlled trial, looking at patients who are 16-50 years old, undergoing hip arthroscopy and osteochondroplasty for femoroacetabular impingement syndrome. All patients will be under general anesthesia, supine on a traction table. They will then undergo hip arthroscopy and associated procedures according to their respective surgeon's typical practice. This will result in different surgical techniques being represented in this study, with variances in portal placement, bone resection strategy, labral repair strategy and capsular closure technique. This is meant to reflect the true practice variances among hip arthroscopists and is inherent in the pragmatic nature of the trial. Participants will be randomized into one of two groups (immediate weightbearing as tolerated vs. touch weightbearing for 6 weeks following hip arthroscopy) in a 1:1 fashion using a computer-generated randomization schedule. Following surgery, all participants will receive a post-operative prescription of acetaminophen for three days, followed by Celebrex daily, and a conservative number of opioids for pain control. All participants will also receive standardized physiotherapy instructions outlining a phased approach from early joint protection and range of motion, to strengthening and sport specific goals in subsequent months. Initially, patients will be restricted to: hip extension 0, flexion 90, abduction 0, adduction 30 and limited external, internal rotation. At 6 weeks patients progress to full ROM and strengthening exercises. Return to sport targets instructions will be patient and sport specific, but generally recommended at 6 months.

Following screening, consent, collection of baseline data, and surgery, patients will be seen post-operatively at 2-weeks, 6-weeks, 3-months, 6-months, 1-year, and 2-years. Patient reported outcomes will be collected at 6 weeks, 3 months, 6-months, 1-year and 2-year appointments.

Intervention

Other:
• Early Weightbearing
Patients randomized to undergo this study intervention will bear weight, as tolerated, on the affected side straight after surgery, with crutches for additional support and stability. They will be allowed to stop using crutches in the weeks after surgery as they feel more comfortable and stable on their surgical leg.
• Protected Weightbearing
Patients randomized to undergo this study intervention will be instructed to be touch weightbearing for 6 weeks after surgery. They will use crutches and put no more weight on the surgical side than what it takes to crack an egg. After the 6-week mark, they will be able to bear weight.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	International Hip Outcome Tool (iHOT-33)	The primary outcome is the difference between the two interventions in their iHOT-33 scores at 1 year post-surgery.; The iHOT-33 questionnaire consists of 33 questions evaluating hip symptoms, functional impairments, sporting activities, job concerns, as well as social and emotional wellbeing. Participants will rate their pain and impairment levels on a scale of 0 to 10, 0 being severe pain/impairment, and 10 being no pain or trouble at all.	Administered at baseline, 6 months, 1 year, and 2 years post-operatively
Secondary	Hip Outcome Score, Activities of Daily Living (HOS-ADL)	The HOS-ADL consists of 17 questions that assess the impact of hip conditions on activities of daily living. Patients are asked to rate the level of difficulty in performing 17 different tasks, on a scale of 0 (unable to perform) to 4 (no difficulty at all).	Administered at baseline, 6 months, 1 year, and 2 years post-operatively
Secondary	European Quality of Life Five Dimension Five Level (EQ-5D-5L)	The EQ-5D-5L assesses patients' overall quality of life and health. This measure asks questions related to mobility, self-care, activity, pain, and anxiety/depression. The measure also includes one 0-100 scale assessing how patients perceive their overall health.	Administered at baseline, 6 months, 1 year, and 2 years post-operatively
Secondary	Pain Visual Analog Scale (VAS)	Participants will indicate their level of pain on a 10cm line that represents a spectrum ranging from no pain (left side), to severe pain (right side)	Administered at baseline, 2 weeks, 6 weeks, 3 months, 6 months, 1 year, and 2 years post-operatively
Secondary	Post-Operative Complications	Incidences of complications such as infection, deep vein thrombosis, restrictions in ROM, adhesive capsulitis, fractures, prolonged opioid use, and early reoperation will be collected and recorded.	Recorded at 2 weeks, 6 weeks, 3 months, 6 months, 1 year, and 2 years post-operatively.
