About this study
Official title: Weight Bearing as Tolerated (WBAT) Following Hip Arthroscopic Labral Repair and Femoroplasty.
This study is being proposed to examine weight bearing precautions following hip arthroscopic labral repair, femoroplasty, and capsular closure. Standard post operative protocols limit weight bearing for 2-6 weeks depending on individual surgeons. Cadaveric studies demonstrate that minimal force during weight bearing is distributed through labrum. Therefore, progressing weight bearing earlier in these patients post operatively may help progress faster and improve outcomes. Data collected will include demographic information, radiological data, operative procedures and PRO data.
Read the detailed description
The study will be conducted at UPMC St. Margaret's Hip Preservation Program. Consented patients who undergo acetabular labral repair and femoroplasty will be included in randomization of weight-bearing status. Two separate protocols will be created to indicate weight bearing status, either WBAT immediately post-op or FFWB immediately post-op, to distribute to rehabilitation staff to ensure compliance. Immediately after the surgical procedure, the surgeon will be blinded and a randomized pamphlet with post-operative instructions with weight bearing education will be given to PACU nursing staff to educate patients and fit crutches.

What is being measured
The primary outcome is the main question the study is designed to answer.
International Hip Outcome Tool 12 (iHot-12)
Scoring ranges from 0-100
- each question is rated from 0-100 and final score is the mean of all questions answered by subject
- higher scoring indicating higher quality of life due to hip function
Measured: up to 6 months post-operative
Hip and Groin Outcome Score (HAGOS)
This outcome includes 6 subscales, these are scored independently, and no aggregate scoring is calculated as each section assesses different dimensions separately.
Subscales (raw scores for each subscale converted to a 0-100 scale with higher score indicating higher level of function):
- Pain
- Symptoms
- Activities of Daily Life
- Function in Sport and recreation
- Participation in Physical Activities
- hip and groin-related quality of life
Measured: up to 6 months post-operative
Hip Outcome Score (HOS) ADL
Outcome assessing function with activities of daily living. Higher score is given for higher level of function and lower score indicating reduced function.
0-68 aggregate scoring converted to 0-100 scale.
Measured: up to 6 months post-operative
Hip Outcome Score (HOS) Sport
Outcome assessing function/difficulty completing dynamic activities associated with sports participation. Higher score is given for higher level of function and lower score indicating reduced function.
0-36 aggregate scoring converted to 0-100 scale.
Measured: up to 6 months post-operative
Tampa Scale for Kinesiophobia-11
Outcome measure assessing fear of pain with movement. Scores range from 11 to 44. Higher scores indicate greater fear of movement
Measured: up to 6 months post-operative
Secondary outcomes (4)
Isometric strength measures hip add, abd, ER, and extension
Strength measures will be taken isometrically at post-operative follow ups.
Measured: 6-week, 3 months, and 6-month post-operative
Diagnostic ultrasound assessment of bilateral anterior hip capsule thickness
Physician while blinded will perform ultrasound evaluation of the hip capsule to ensure healing.
Ultrasound will measure the following:
1.Assess the bilateral hip anterior capsule in all patients, assessing for internal consistency or changes in capsular thickness from side to side. Normal hip capsular thickness has been reported as 7-8 mm, dysplastic hips range 3.2 +/- 0.5 mm, and femoroacetabular impingement subjects 4.7 +/- 0.6 mm.
Measured: 3 months post-operative
Diagnostic ultrasound assessment of incision widening
Physician while blinded will perform ultrasound evaluation of the hip capsule to ensure healing.
- Evaluation of capsular incision widening, cyst, attenuation and thinning from established norms. Normal hip capsular thickness has been reported as 7-8 mm, dysplastic hips range 3.2 +/- 0.5 mm, and femoroacetabular impingement subjects 4.7 +/- 0.6 mm
Measured: 3 months post-operative
Diagnostic ultrasound for focal echogenic adhesions
Physician while blinded will perform ultrasound evaluation of the hip capsule to ensure healing.
- Evaluate for focal echogenic adhesions or dyskinetic motion between capsule and overlying iliopsoas complex with activation of hip flexion.
Measured: 3 months post-operative
