Peroneal Tendinopathy
Lower LimbOverview
Peroneal tendinopathy is a chronic overuse condition affecting the peroneus longus and/or brevis tendons, characterized by pain and dysfunction along the lateral aspect of the ankle and lower leg. This condition commonly results from repetitive inversion ankle movements, chronic ankle instability, or biomechanical dysfunction. Conservative management including activity modification, manual therapy, and progressive rehabilitation typically yields favorable outcomes.
Pathophysiology
Peroneal tendinopathy develops through cumulative microtrauma from repetitive loading or chronic lateral ankle instability, leading to degenerative changes within the tendon matrix, inflammation of the paratenon, and potential subluxation or dislocation of the tendons around the lateral malleolus. The tendons run in a groove posterior to the lateral malleolus; abnormal foot mechanics, ankle laxity, or anatomical variations can cause friction and mechanical irritation. Intratendinous degeneration involves collagen disorganization, neovascularization, and proteoglycan accumulation without acute inflammatory infiltration.
Typical Presentation
Site
Lateral ankle and lower leg, specifically along the path of the peroneal tendons posterior to the lateral malleolus; may extend into the lateral midfoot and dorsolateral foot
Quality
Aching, burning, or sharp pain; possible clicking or snapping sensation indicating subluxation
Intensity
Variable mild to moderate pain, typically 3-6/10, worsening with activity and easing with rest; may have periods of acute exacerbation
Aggravating
Inversion movements, walking on uneven surfaces, running or jumping, prolonged weight-bearing, tight footwear, rapid directional changes, activities requiring plantarflexion and eversion against resistance
Relieving
Rest, ice application, ankle support or strapping, gentle movement, elevation, anti-inflammatory modalities
Associated
Chronic ankle instability, recurrent ankle sprains, proprioceptive deficits, peroneal muscle weakness, reduced ankle dorsiflexion range, swelling along lateral ankle, possible foot pronation, gait abnormalities
Orthopaedic Tests
Peroneal Tendon Palpation
Procedure
Patient seated or supine with knee flexed. Palpate along the retromalleolar groove and peroneal tendon sheath posterior and inferior to the lateral malleolus, moving distally along the peroneal tendons.
Positive Finding
Localized tenderness, swelling, or crepitus along the peroneal tendon course
Sensitivity / Specificity
Unknown / Unknown
Interpretation
Highly sensitive for peroneal tendinopathy when combined with pain reproduction and history; non-specific finding that should be correlated with clinical presentation and imaging
Peroneal Tendon Resisted Eversion
Procedure
Patient supine or seated. Examiner stabilizes the lower leg and applies resistance as patient actively everts the foot against manual resistance.
Positive Finding
Pain or weakness along the lateral ankle and peroneal tendon region during resisted eversion
Sensitivity / Specificity
Unknown / Unknown
Interpretation
Reproduces pain in peroneal tendinopathy due to load on the tendon; good indicator of functional impairment and tendon involvement
Ankle Inversion Stress Test (Anterior Talofibular Ligament Test)
Procedure
Patient supine or seated with knee slightly flexed. Examiner inverts and plantarflexes the foot to stress the anterior talofibular ligament and lateral ankle complex.
Positive Finding
Pain or apprehension in the lateral ankle; excessive inversion range if ligament is torn
Sensitivity / Specificity
72% / 96%
Hegedus et al., 2012, British Journal of Sports Medicine
Interpretation
Peroneal tendinopathy often coexists with lateral ankle instability; a positive test suggests associated ligamentous injury or chronic instability that may contribute to tendinopathy
Single-Leg Stance or Single-Leg Hop Test
Procedure
Patient stands on affected leg with arms crossed or at sides, maintaining balance; alternatively, perform a single-leg hop for distance or time.
Positive Finding
Pain reproduction along the peroneal tendons, loss of balance, or lateral ankle giving way
Sensitivity / Specificity
Unknown / Unknown
Interpretation
Functional test sensitive to proprioceptive deficits and tendon loading; pain suggests peroneal tendon involvement during weight-bearing and dynamic activities
Long Peroneal Tendon Palpation Test (Distally Along Fifth Metatarsal Base)
Procedure
Patient supine or seated. Palpate the peroneal longus tendon as it courses under the lateral foot and inserts on the medial cuneiform and first metatarsal base.
Positive Finding
Tenderness, swelling, or pain along the inferior lateral foot and plantar aspect near the fifth metatarsal tuberosity
Sensitivity / Specificity
Unknown / Unknown
Interpretation
Identifies involvement of the peroneal longus tendon in its distal course; important for assessing the full length of the tendon and ruling out stenosis or subluxation
Peroneal Tendon Subluxation Test (Circumduction)
Procedure
Patient in seated or supine position. Apply external rotation and dorsiflexion of the foot (circumduction maneuver) while palpating posterior to the lateral malleolus to detect tendon displacement.
Positive Finding
Visible or palpable 'popping' or subluxation of the peroneal tendons out of the retromalleolar groove; reproduction of sharp lateral ankle pain
Sensitivity / Specificity
42–73% / 88–96%
Hegedus et al., 2012, British Journal of Sports Medicine; Reiman et al., 2013, Journal of Athletic Training
Interpretation
Indicates peroneal tendon instability or retinacular laxity, a mechanical cause of peroneal tendinopathy; helps identify structural predisposition to injury
⚠ Red Flags
- •Severe trauma or fracture suspected (obtain imaging)
- •Signs of deep vein thrombosis (calf swelling, warmth, positive Homan's sign)

- •Systemic inflammatory conditions (rheumatoid arthritis, seronegative spondyloarthropathy)
- •Unexplained significant swelling or constitutional symptoms
- •Tendon rupture with loss of eversion strength
⚡ Yellow Flags
- •High kinesiophobia or fear of movement related to ankle instability
- •Psychological distress from recurrent ankle injuries
- •Occupational demands requiring high ankle stability without adequate support
- •Poor compliance with rehabilitation due to perceived prognosis
- •Secondary gain from chronic ankle dysfunction
- •Perfectionist personality with excessive training load
Osteopathic Techniques
Region
Lateral ankle and peroneal tendon
Technique
Soft Tissue
Rationale
Soft tissue mobilization along the peroneal muscles and tendons reduces paratenon irritation, improves local circulation, and promotes fascial rehydration. This technique is particularly effective in chronic tendinopathy where mobility restrictions contribute to continued irritation.
Region
Talofibular and tibiofibular joints
Technique
Articulation
Rationale
Gentle articulation of the ankle and subtalar joints restores normal arthrokinematics, reducing abnormal shear forces on the peroneal tendons. Improved ankle joint mechanics decrease compensatory tendon loading.
Region
Fibula
Technique
MET
Rationale
Muscle energy technique targeting peroneal muscles improves neuromuscular control and reduces muscle guarding. MET is effective for restoring balanced ankle stabilizers without aggressive loading.
Region
Lower leg and ankle
Technique
Lymphatic
Rationale
Lymphatic drainage techniques reduce swelling and inflammation around the tendon and peroneal compartment, improving tissue fluid dynamics and facilitating healing. This modality is valuable in acute exacerbations.
Region
Proximal tibiofibular joint and knee
Technique
HVLA
Rationale
Proximal tibiofibular mobilization restores normal fibular mechanics, which directly influences tension on the peroneal tendons distally. Improved proximal stability reduces compensatory ankle stress.
Region
Lumbar spine and sacroiliac joint
Technique
Articulation
Rationale
Addressing proximal biomechanical dysfunction (lumbar or pelvic asymmetry) reduces aberrant lower limb loading patterns that contribute to chronic ankle stress and peroneal tendinopathy.
Add-On Approaches
Chinese Medicine
