Weight Bearing Status Post-hip Arthroscopy

Not Applicable
Conditions
Hip Impingement Syndrome
Acetabular Labral Tear
Interventions
Other: Flat foot weight bearing (FFWB) immediately following surgery
Other: Weight Bearing as tolerated (WBAT) immediately following surgery.
Registration Number
NCT05720806
Lead Sponsor
University of Pittsburgh
Brief Summary

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.

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.

Primary Outcome Measures
NameTimeMethod
International Hip Outcome Tool 12 (iHot-12)up to 6 months post-operative

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

Hip and Groin Outcome Score (HAGOS)up to 6 months post-operative

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

Hip Outcome Score (HOS) ADLup to 6 months post-operative

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.

Tampa Scale for Kinesiophobia-11up to 6 months post-operative

Outcome measure assessing fear of pain with movement. Scores range from 11 to 44. Higher scores indicate greater fear of movement

Hip Outcome Score (HOS) Sportup to 6 months post-operative

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.

Secondary Outcome Measures
NameTimeMethod
Isometric strength measures hip add, abd, ER, and extension6-week, 3 months, and 6-month post-operative

Strength measures will be taken isometrically at post-operative follow ups.

Diagnostic ultrasound assessment of bilateral anterior hip capsule thickness3 months post-operative

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.

Diagnostic ultrasound assessment of incision widening3 months post-operative

Physician while blinded will perform ultrasound evaluation of the hip capsule to ensure healing.

1. 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

Diagnostic ultrasound for focal echogenic adhesions3 months post-operative

Physician while blinded will perform ultrasound evaluation of the hip capsule to ensure healing.

1. Evaluate for focal echogenic adhesions or dyskinetic motion between capsule and overlying iliopsoas complex with activation of hip flexion.
