Question 1

failure strength of the normal rotator cuff is:

Answer 1

2400 N

245 Kg

Question 2

Failure strenght of the rotator cuff in the first 6 wekks postop is:

Answer 2

200 - 400 N

20 - 40 Kg

Question 3

Failure strenght of the rotator cuff at 12 weeks postop is:

Answer 3

700 N

71 Kg

Question 4

Clinical Pearl: the strength of the surgical repair always should be much greater than the mechanical stress that is placed on the repaired tendon during rehabilitation (manual therapy, clinic exercises, HEP)

at 12 weeks post RCT surgery, what is the maximum strength force that can be applied to the repaired tendon?

Answer 4

At 12 weeks failure strength is 700N, normal strength is approximately 6 months

so around 500 N

Question 5

Clinical Pearl: the strength of the surgical repair always should be much greater than the mechanical stress that is placed on the repaired tendon during rehabilitation (manual therapy, clinic exercises, HEP)

at 6 weeks post RCT surgery, what is the maximum strength force that can be applied to the repaired tendon?

Answer 5

First 6 weeks after surgery failure strength is 200­-400N

so around 100 N

Question 6

Codman’s pedulum

Answer 6

• done immediately after RCT repair
• prevents adhesion
• every day, every hour
