FOOT AND ANKLE - ACHILLES TENDON INJURY
- Must decipher whether the tendon is ruptured or not ruptured
- If it is not ruptured it is further classified as to whether the problem exists at the attachment site of the Achilles on the calcaneus “insertional” or if symptoms exist proximal to this area “noninsertional”
FOOT AND ANKLE - ACHILLES TENDON INJURY - NONINSERTIONAL TENDINOSIS
- When there is actual intratendinous degeneration of the Achilles tendon proximal to its attachment on the calcaneus
- Tendon is typically swollen
- Onset of symptoms is insidious and located within the midsubstance of the tendon
- Its not called ‘tendonitis’ because history reveals no true inflammatory component instead a fibromyxoid degenerative tissue with a high water content replaces normal tendon
FOOT AND ANKLE - ACHILLES TENDON INJURY - INSERTIONAL TENDINOSIS
- An inflammatory condition
- Occurs at or around the Achilles tendon insertion into the calcaneus
FOOT AND ANKLE - ACHILLES TENDON INJURY - RUPTURE
- Most common tendinous rupture in the lower extremity
- Peak incidence in the 3to 5decades and occurs 5 times more often in males
- Described in middle-aged athletes who have experienced a sudden pain with an audible “pop” in the back of the heels
- Many report a sensation of being hit even when they haven’t
FOOT AND ANKLE - ACHILLES TENDON INJURY - RISK FACTORS
- Males
Noninsertional
- Repetitive microtrauma
- Aging
Insertional
- Hill running
- Interval workouts
FOOT AND ANKLE - ACHILLES TENDON INJURY - POPULATION AFFECTED
- 30-50 (For a rupture)
FOOT AND ANKLE - ACHILLES TENDON INJURY - CLINICAL PRESENTATION
- Pain is the cardinal symptom of Achilles tendinopathy
- In the early phase of insertional and noninsertional tendinopathy pt may complain mainly of pain following strenuous activity and if progressive can develop pain that accompanies routine activities
- Decreased ankle dorsiflexion
- Hamstring tightness
- Note the contour of the tendon, any areas of widening and the presence or absence of nodules
FOOT AND ANKLE - ACHILLES TENDON INJURY - CLINICAL PRESENTATION - NONINSERTIONAL
- Likely due to the tendon having a sparse cellularity and vascularity
- Both of which impair the inflammatory process
- As a result, the tendon becomes thicker, softer, and yellowish
- Degeneration of the tendon is often insidious and asymptomatic
- Swelling and pain typically 4cm proximal to the distal insertion of the Achilles
FOOT AND ANKLE - ACHILLES TENDON INJURY - CLINICAL PRESENTATION - INSERTIONAL
- Often associated with the Haglund deformity
- Posterior heel pain thought to be due to bony impingement from the calcaneus, local bursitis, or both
- If the tendonitis becomes chronic the tendon can also become palpably thickened
FOOT AND ANKLE - ACHILLES TENDON INJURY - CLINICAL PRESENTATION - RUPTURE
- Symptoms differ
- Pt with partial tears will complain of more pain than those with complete ruptures
- Pt with Achilles rupture will be unable to plantarflex the ankle
- The Thompson test is sensitive in picking up a rupture
