Quadriceps Tendon Rupture

Epidemiology

 

Usually occurs in patients over 60

- due to decreased vascularity & collagen weakness

 

Younger patient on steroids / growth hormone

 

Occasionally occurs in young athlete with excessive contracture

 

Aetiology

 

Often preceded by quadriceps tendinosis

 

Achilles Tendon Rupture

AnatomyAchilles tendon anatomy

 

Gastrocnemius tendon 10-25 cm long

- soleus 3-10 cm

- inserts superior calcaneal tuberosity

- fibres spiral 90°

- fibres that lie medially in proximal portion become posterior distally

- allows elastic recoil & energy storage

 

Plantaris present in 90% population

- medial to T Achilles

 

Poor blood supply midportion

- mesotenal vessels
