Hip Arthroscopy is a Means, Not an End
• Restore anatomy to:
– Relieve pain
– Improve function
– Improve longevity?
CAM lesion Bump removal vs. Sphericity
Pincer lesion Rim Trimming vs. Femoral Osteoplasty
Torn labrum Repair vs. Debride vs. Reconstruct
Cartilage defects Microfracture, Repair, Rim Trim
Instability Plication, capsular shift
Dysplasia Arthroscopy vs. PAO
Approach Open vs. Arthroscopic
Early arthritis Symptomatic Relief vs. 2 Surgeries
What Should We Treat?
• Make the correct diagnosis!

Fig. 1
A list of static and dynamic mechanical factors for prearthritic hip pain. AIIS = anterior inferior iliac spine, FAI = femoroacetabular impingement, SI = sacroiliac joint, and ITB = iliotibial band.
Figure legend:
• Make the correct diagnosis
• History and Physical are critical• Understand concomitant disease (i.e.,
sports hernia, lumbar spine pathology, etc.)
• Understand that there may be a mixed picture of symptoms such as sacroillitis, peri-pelvic tendinitis, ischial or troch bursitis
What Should We Treat?
6
• Traumatic vs. Insidious– Twisting or torqueing
– Subluxation
– Dislocation, associated fracture
• Congenital / Developmental– DDH, Perthes, SCFE
• Other– Infection, PVNS, Osteonecrosis, Synovial
Chondromatosis
History

Confirming the source of pain
• History
– Is it predominately lateral or posterior?
– Or is it in the groin?
– Pain and/or numbness going down the leg?
Confirming the source of pain
• History
– Can you push on it and make it hurt?
– Does your hip make noise?
– When it pops, does it hurt?
Confirming the source of pain
• History – What causes the
pain?–Twisting
–Running
–Prolonged sitting– Plane rides/ long car
rides
–Walking uphill
–Getting in/out of car
–Achy night pain?
Confirming the source of pain
• Where does it hurt?
• C-sign
Confirming the source of pain
• Intra-articular etiologies

Joint capsule:LaxitySprainTightnessTear
Ligamentum teres tearInternal impingement
Bony deformities:FAIDDHSCFEPerthesStress fx.
OsteonecrosisLoose bodiesTransient synovitisInfection
Confirming the source of pain
• Extra-articular etiologies
Bursitis:TrochantericPsoasIschial
Muscular strain:IliopsoasGluteus mediusHamstrings
Snapping hip:ITBIliopsoas
Avulsion injuriesStress fractureSI pathologyMyositis ossificansHip pointerInfection
Confirming the source of pain
• Many patients don’t follow the textbook– Combined back and
groin pain
– Troch and groin pain
– Butt and groin pain
– Groin pain but negative anterior impingement sign
– Achy night pain
Inspection: Postural Analysis (Static)
Shoulder to Foot Symmetry
Inspection: Dynamic
• Sport performance• Standing single leg
squat• Trendelenburg• Standing single leg
raise• Sit-up• “Make it pop”
Palpation: Anterior Checklist
• Rectus Abd Insertion
• Pubic bone• Ext inguinal ring• Lower abd
quadrant• AIIS: direct rectus
femoris• ASIS• Anterior 1/3
Gluteus Medius/Tensor
Palpation: Posterior Checklist
• Paraspinous/axial spine
• SI joints• Ischial tuberosity• Posterior Iliac
Crest• Sciatic notch?
Range of Motion: Supine/Prone
• Assess ranges:– Flexion
– Extension
– ROTATION prone and supine at 90 deg flexion
• Knee / Lumbar
Special Tests• Sensitive NOT
specific• Impingement• Laxity / Instability• SI joint• Piriformis Syndrome• ITB syndrome• HNP lumbar spine• Core Muscle Injury
(Sports Hernia)• Standard hernia
(valsalva)
Anterior Impingement TestPassive flexion to 90°
followed by forced adduction and IR

FABER Test
Vad et al. Am J Sports Med 2004
Confirming the source of pain
• Diagnostic injections
– Can be very helpful
– Consider using corticosteroid, not just lidocaine/marcaine
Confirming the source of pain
• Diagnostic injections– Inject other
potential sources of pain if clinically warranted
– Iliopsoas
– Troch bursa
– Piriformis
– SI joint
– Spine
Confirming the source of pain
•It’s the hip…now what?
•In non-arthritic hips most common source of pain is labral pathology secondary to FAI
Acetabular Labrum• Extends the
acetabulum beyond the bony socket
• Is present around the entire lunate surface of the acetabulum
• Is continuous with the transverse acetabular ligament inferiorly
Femoroacetabular Impingement
• Wenger et al. showed that 87% of patients with labral tears had underlying structural abnormalities (Wenger et al. CORR 2004)
• Ganz and colleagues introduced the concept of Femoroacetabular Impingement (FAI) as a cause of hip pain, labral tears, and early osteoarthritis(Ganz et al. CORR 2003)

Set Up - Initial position• Complete Paralysis• Perineal pad, padded boots, foot holder• Start with legs abducted approx. 45

Check Fluoroscopic Images

Pincer ImpingementPincer Impingement• Overcoverage of the acetabulum on the femoral headOvercoverage of the acetabulum on the femoral head
• Global or localGlobal or local
Rationale
1. Directly address the offending pathology causing impingement in pincer-type or mixed pincer-cam-type FAI
2. Protect from further impingement damaged labrum which has been repaired/reconstructed.
3. Resect areas of grade IV chondral damage

• Pre Operative PlanningPre Operative Planning– Know your goalsKnow your goals
– Focal resection for Focal resection for retroversion or general retroversion or general decompression for coxa decompression for coxa profunda profunda
– Measure LCEA, Acetabular Measure LCEA, Acetabular Inclination Angle and femoral Inclination Angle and femoral neck-shaft angle from AP pelvisneck-shaft angle from AP pelvis
– Measure ACEA from false Measure ACEA from false profileprofile
– Be cognizant of significant Be cognizant of significant femoral anteversionfemoral anteversion
Operative TreatmentOperative Treatment
• Pincer Bony ResectionPincer Bony Resection– Philippon, Wolff et al. Philippon, Wolff et al. Arthroscopy Arthroscopy
20102010– Change in the CE angle could be
determined by the following formula: Change in CE angle = 2.2 + (0.2 x [rim reduction in millimeters]).
– General rule: General rule:
The CEA decreases 2 degrees for The CEA decreases 2 degrees for every mm of bone resectedevery mm of bone resected
– Bottom line:Bottom line:– Don’t over-resect acetabular rimDon’t over-resect acetabular rim– Be cautious if CEA<30Be cautious if CEA<30
– Especially if acetabular Especially if acetabular inclination level is >10inclination level is >10
• If you take it off . . . – PUT IT BACK
• Beware small labrum (anterior zone)
• Beware DYSPLASIA!
• If it’s torn traumatically . . . – More rare– Fix when you can– Remove what you
must– Think “hoop fibers”
– No segmental resection
Post-op care
• Crutch-aided walking for 2-3 weeks
• PT x approx 12 weeks
• Return to full activities 3-6 months
Post-operative Principles
• Properly done post-operative rehab is crucial
Post-operative Principles
• Commonly seen problems– Hip flexor tendonitis
– Avoid active hip flexion and hip flexor strengthening for as long as possible
– Anterior hip capsule contracture– Early stretching gentle stretching can help– At 6 week mark, if motion not progressing
will have patients spend minimum of 10 minutes daily in prone FABER position getly pressing pelvis to floor
Post-operative Principles
• Commonly seen problems
– Limp– Patients should remain on crutches until
they are able to walk with normal gait
– Emphasize normal gait pattern – heel to toe with achievement of terminal stance and hip extension for toe off of involved.
Post-operative Principles
• Soft tissue mobilization and stretching– Scar massage at week 2– Initial soft tissue massage gently at
weeks 1-2-- iliopsoas, rectus femoris, adductors gluteus medius and piriformis.
– Progress to more aggressive soft tissue work at week 4 if needed
– active release, dry needling, Graston techniques can be very helpful
Post-operative Principles
• Aquatic Therapy
– Can be a very useful adjunct
– Not mandatory
– Can begin at 2 weeks post-op
Post-operative Principles
• Can see full post-op protocol and aquatic therapy protocol at: www.andrewwolffmd.com
• Protocol is in evolution. Suggestions welcome.
