Q

What is the disadvantage of preserving the PCL during a TKA?

A

impairs rollback of the femur on the tibia since PCL can be tight, and it also has decreased mechanical advantage of the quads

31
Q

What phase 3?

A

OP rehab

32
Q

What are the two types of THA?

A

conventional and hip resurfacing

33
Q

What are the two parts of the conventional THA?

A

replacement of the acetabular cap

replacement of femoral head

34
Q

What are the 3 types of the femoral head/stem components?

A

cemented
porous
hybrid

35
Q

Anterior Approach: where? risk? avoid? pro?

A

TFL and satrorius
lateral femoral cutaneous nerve
avoid excessive hip extension
has shorter recovery time

36
Q

Anteriorlateral Approach: where? risk? avoid? pro?

A

TFL and Glut MED
abductor muscles can be detached and superior gluteal and femoral nerve
avoid excessive hip extension, abd, ER
good for CVA pt to allow flexion and add

37
Q

Posterolateral Approach: where? risk? avoid? pro?

A

Glut Max
risk of traction injury of sciatic and superior glut nerve
avoid hip flexion 90, adduction, IR

38
Q

THA dislocation of an Anterior approach pt and Posterolateral pt may look like what?

A

Ant: ER
PostLat: add & IR

39
Q

who gets Hip resurfacing vs THA?

A

young active pt <60 years old

40
Q

What are 3 major benefits of hip resurfacing?

A
  • load though the hip is better distributed with better ROM
  • more hip stability
  • lower incidence of dislocation (0.5% vs 3.0%)
41
Q

What are 3 major risks with hip resurfacing?

A
  • chromium ion dispersal resulting in inflammation
  • femoral neck fx
  • heterotopic ossification
42
Q

THA phase 1: intiating exercise allowed are?

A
  • iso: quad & glute sets
  • active and AA: ankle pumps, knee ext, SAQ, heel slides to 45 deg,
  • breathing exercise spirometry
43
Q

How long does THA precautions last?

A

at least 6-8 weeks.

44
Q

When transferring OOB for THA what side?

A

Right THA: right side

45
Q

THA Phase 1: goal?

for independence with ambulation, transfer, stairs using non-reciprocal pattern

46
Q

THA Phase II: where?

A

IRF
SNF
Homecare

47
Q

THA OP: when and goals?

OA/RA/Post-traumatic arthritis, RTC arthropathy, AVN/osteonecrosis, failed previous TSA, severe fx

50
Q

What are 3 indicators for conventional TSA?

A
  • intact RTC
  • some active ROM
  • pain is generally the main issue
51
Q

What are 3 contraindicators for conventional TSA?

A

  • pt unwilling to be a good PT pt
52
Q

Conventional TSA: post-op 0-4 weeks: what is recommended?

A
  • Codman
  • PROM 90 flexion and abd
  • PROM MD orders, usually 10 deg below prior
  • AROM of elbow, wrist, hand
53
Q

With TSA: post-op 0-6 weeks: what active motion is not allowed?

A

No active IR.
instead provide scapulothoracic mobs.
and AAROM with MD clearance

54
Q

What are 3 conventional TSA OP goals?

A
  • restore AROM and deltoid and rtc strength
  • maximize scapulothoracic, elbow, and neck mobility
  • 135 flexion, 90 abd, 45 ER/IR or to L4 spinous process
55
Q

rTSA is aka what?

A

reverse ball and socket TSA

56
Q

What are 5 major indicators for rTSA?

A
  • no RTC
  • no AROM of shoulder
  • presents as pseudoparalytic
  • irreparable RTC
  • > 65 y.o.
57
Q

with rTSA it will move the joint line which direction?

A

lateral

58
Q

rTSA will improve biomechanics of what muscle in what direction?

A

Deltoid; flexion * abduction

59
Q

What are 3 major contra indicators for rTSA?

A
  • structure/neuro lesion of the deltoid
  • glenoid damage without good bone for anchoring
  • <65 y.o.
60
Q

For rTSA how many weeks post-op of no PROM?

A

4 weeks

61
Q

rTSA post op allows for what AROM?

A

elbow, wrist, hand

62
Q

rTSA in OP what muscle group do you not need to work on?

A

ER

63
Q

Since there is no RTC with rTSA, what is precaution?

A

jamming of prostheses and resulting in loosening, deltoid overpowers @ shoulder

64
Q

What are the 3 main goals for rTSA in the OP setting?

A
  • increase AROM flex & abd
  • increase MMT of deltoid
  • increase mobility of scapulothoracic
