Q

What anatomic variable should be taken into consideration when deciding if a hip impingement can be perform arthoscopically?

A

the amount of hip joint cartilage

- less than 2mm or cartilage does poorly with arthroscopy

Q

What tissues are involved in a hip arthroscopy for impingments

A
  • bone - debrided edges

- labrum - very week and is the weak point through the inflammatory and reparative stage

Q

What precaution do you need to take into account during the inflammatory stage of hip impingement arthorscopy

A
  • labrum is very week and you do not want to push the femoral head into the repaired tissues
  • no hip extension or ER
  • flexion no greater than 120 and abduction to 45
  • limited weight bearing for a least 2 weeks
  • avoid supine SLR and sidling abduction as these exercise are likely to be to hard at this time

Q

Describe the state of the different tissues during the reparative stage of healing

A

reparative 5-7 weeks

  • wound - scar tissue and revascularization
  • bone - callus formation
  • labrum - type III being replaced by Type II

Q

What diagnostic test series is best for diagnosis hip impingement syndrome

A
  1. hip impingement test
  2. FABER

Q

Kivlan’s 2012 systematic review identified what functional performance test as valid assessments of hip dysfunction

A
  1. deep squat test - was valid for FAI
  2. single leg squat difference was valid for muscular impairment
  3. STAR excursion
  4. 30 second single leg stance pain gluteal tendonopathy and ruling out referral from other area

16
Q

Risk factors

A
  • physiologic - core and LE strength neuromuscular control

- anatomic

17
Q

What is the difference between an ALC coper and Non-coper

A

copers return to normal function and performance without ACL
- non-copers don’t and tend to be older, non-contract injuries, female and have feelings of instability

18
Q

what is the difference between autograft and alograft

A

auto - your body

alo - cadaver

19
Q

how does the bone healing vary in the difference parts of a bone tendon bone ACL surgery

A

tunnels heal faster than the graft sites

20
Q

Describe the healing process of the ACL autograft

A

1 - very strong when implanted, goes into inflammation
2- 4 weeks cellular proliferation, weakest point of the graft
3- 6 weeks vascular proliferation
4- vascular prunning
5- 3 months matrix remodeling
6- healed 12-16 months

21
Q

Criteria for return to run

A
  • no dynamic valgus collapse with repetitive single leg exercise
  • 70% strength
  • no complaints of giving away
22
Q

How does the tensile strength of the new ACL compare to native ACL

A

1-2 years post op the repaired ACL has only 20-30% of native tensile strength

23
Q

what component of the return to sport does the AC return sport injury scale assess

A

psychologic

24
Q

How doe the healing phases of autologous chondrocyte implantation differ

A
  1. healing begins in the lab where harvested cells are grow
  2. femoral defects have longer weight bearing restrictions
  3. full ROM and strengthening don’t start until about 6 weeks
25
Q

ACI outcome prognosis variable

A
  1. High BMI
  2. large or kissing lesions
  3. marrow stimulation helps

OUTCOME measures include -Womac, knee society score, modified Cincinnati knee rating

26
Q

Risk factors for achilles tendon tear

A
  • male in the 4th to 5th decade
  • running, jumping and agility activities involving eccentric loading and explosive plyometrics
  • fluorqauinolone antibiotic use (cipro, factive, levaquin, avelox, noroxin, floxin) common broad spectrum antibiotic
  • corticosteroids are questionable, but in combination with fluroquainalone is bad
27
Q

what intrinsic risk factors are there for achilles tendon repair

A
  1. smokers
  2. poor skin heal at surgical site
  3. DM
  4. chronic steroidal medical use
28
Q

How soon is motion and weight bearing start after achilles tendon repair

A

Marked variance

  • NWB and casted about 4 weeks
  • some surgeons are WB sooner within the first two weeks (tissue healing phase still the same)
29
Q

what outcome scores have been validated for achilles tendon ruputures

A
  • achilles tendon total rupture score
  • foot and ankle ability measure (FAAM)
  • american orthopedic foot and ankle society hind foot score
30
Q

Does the early motion protocol or delayed motion protocol for achilles tendon rupture have better outcomes

A

Short term the early motion protocol has earlier functional return, but in the long term they are equal
