Q

3 important things in ACL sprain rehab (conservative)

A
  1. terminal knee extension ROM (hard to get back)
  2. Hamstring strengthening
  3. CKC = less shear forces (more proprioceptive feedback = add to rehab program)

Q

Does not often require surgery due to its MOI

A

PCL sprain

20
Q

For meniscus tears, what is included in the 3-6 months of conservative treatment?

A

Quad strengthening, hamstring strengthening, activity modification, unloader bracing, NSAIDs, and neuromuscular retraining

21
Q

Purpose of the unloader brace

A

Puts pressure on the outside of the knee, to open the space to decrease the irritation

22
Q

Kinematics of IT band friction syndrome

A

Greater hip adduction, greater contralateral pelvic drop

23
Q

4 things to do in IT band friction syndrome

A
  • Decrease training load, running speed, hill work
  • Stretch the lateral chain (3x a day)
  • Strengthening of the gluteus medius
  • Possible change in running shoes
24
Q

Patellar tendinopathy rehab, what to avoid in activity modification?

A

Avoid jumping and implement stretching in early part of disease

25
Q

Do we use eccentric exercises in patellar tendinopathy, why?

A

YES, load on patellar tendon can be maximized

26
Q

Type of brace for patellar tendinopathy

A

Patellar strap

27
Q

Kinematics of patellar tendinopathy

A

Peak hip adduction and ankle eversion were higher in runners and tibial IR/ER was lower with PT compared to control group

28
Q

Kinematics of PFPS

A

Excessive IR of femur increase stress on patellofemoral joint, excessive pronation

29
Q

For what injury is the balance between vastus medialis and vastus lateralis is important?

A

PFPS rehab

30
Q

PFPS - in long run, ___ exercises promoting co-contraction of HS and quads has been shown to be superior

A

OKC

31
Q

PFPS, strengthen what?

A

Isolated strengthening of quadriceps (both in OKC and CKC)

32
Q

2 predisposing factors to hamstring strain

A

Strength and control of the lumbopelvic structures + quadriceps tightness

33
Q

Type of strengthening for hamstring strain?

A

Eccentric strength

34
Q

___ and __ shown to be superior to standard stretch and strengthening in hamstring strain rehab

A

Trunk stabilization and agility

35
Q

Why is a hamstring strain rehab so long?

A

Because athlete RTP too soon (use taping, bracing, until end of season, play with pain)
and because it takes time to change the postural motions that causes it (ex: anterior pelvic tilt)

36
Q

Typical muscle of quadriceps that his strained

A

Rectus femoris

37
Q

What exercises are targeted for rehab of quad strain? (4)

A

Stretching, strengthening, proprioceptive, and functional training exercises

38
Q

Complication of quad strains

A

Myositis ossificans

39
Q

What to do in the first 24-48h with a quad contusion?

A

Stretching

40
Q

Kinematics of patellar dislocation

A

Patellar/femur structure, medial and lateral retinaculum, valgus forces on knee

41
Q

Can you use taping for patellar dislocation?

A

YES

42
Q

Goal of patellar dislocation rehab (general)

A

Decrease swelling
Promote VMO and gluteal activity

43
Q

What to use for ROM of the knee in early rehab of patellar dislocation?

A

Bike

44
Q

Patellar dislocation - literature is leaning towards ___ more effective than __ strengthening

A

more CKC than OKC

45
Q

Patellar dislocation - common to see knee lock/unlock at 20-30d, what to do to correct? (3)

A

Mini squats
VMO and VL timing emphasis
Optimal lower body alignement re-training

46
Q

Excellent exercise for gaining ROM

A

Exercise bike (pendulum = full revolutions)
