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

 

De Quervain syndrome

Definition

 

Stenosing tenosynovitis of the first dorsal compartment of wrist

 

Epidemiology

 

Most are middle aged women

 

Aetiology

 

Repetitive thumb movements

- abduction & extension

- combined with RD & UD movements

 

Any mechanical irritation

- foreign body

- prominent bony surface

- restricted fascial compartment

Patella Tendon Rupture

Epidemiology

 

Usually occurs in young people

- often previous history of tendonitis ± steroid injections

 

Location

 

Usually at level of inferior pole of patella

- less common at tibial tubercle

- mid-substance ruptures rare

 

Clinical

 

Severe pain

Palpable defect

Extensor deficit / unable to SLR

 

Xray

 

Patella alta / high riding patella

 

Chronic PLC Management

Issues

 

Limb alignment

 

Risk that late posterolateral corner reconstruction will fail in the setting of the varus knee

- varus knee alignment and varus thrust in stance phase

- consider osteotomy first in this setting
