Medial Tibial Stress Syndrome
Lower LimbOverview
Medial tibial stress syndrome (MTSS), commonly known as shin splints, is an overuse injury characterised by pain along the medial tibia resulting from repetitive stress to the tibialis posterior and surrounding structures. It is prevalent in running and jumping sports and typically presents as exercise-induced pain that resolves with rest. The condition represents inflammation and microdamage to the periosteum and muscle-tendon interface rather than a stress fracture.
Pathophysiology
MTSS develops through repetitive microtrauma from excessive tibialis posterior muscle contraction and traction on the periosteum. Increased training volume or intensity, combined with inadequate recovery, overwhelms tissue tolerance. Inflammation of the periosteum and muscle-tendon junction results in pain. Poor dorsiflexor strength and calf inflexibility contribute to altered biomechanics and increased demand on the tibialis posterior. The condition exists on a continuum and, if unaddressed, can progress toward stress fracture.
Typical Presentation
Site
Medial tibial border, typically in the middle third of the tibia; may extend along the entire medial aspect; usually unilateral but can be bilateral
Quality
Sharp, aching, or throbbing pain; described as burning or deep ache along the shin; reproducible on palpation of the medial tibial periosteum
Intensity
Mild to moderate; typically 4-7/10; worsens with activity and improves with rest; may wake athlete from sleep in severe cases
Aggravating
Running, jumping, or high-impact activities; sudden increase in training volume or intensity; downhill running; hard training surfaces; inadequate footwear; tight calf muscles
Relieving
Rest from impact activities; ice application; elevation; low-impact cross-training; massage; stretching and foam rolling of calf and tibialis posterior
Associated
Foot pronation; tight calves and anterior tibialis; weak hip abductors and external rotators; limited ankle dorsiflexion; postural deviations (knee valgus); pain with heel walking; positive dorsiflexion resisted test
Orthopaedic Tests
Test descriptions are written with AI assistance from standard clinical texts. Where a test lists Sources, its description has been checked against them; those sources are independent and do not endorse OsteoKit. Accuracy figures and grades (A–D) appear only when checked against the published study; tests without one are marked “No accuracy study”.
Further reading: full test procedures are described in standard clinical examination texts, e.g. Magee & Manske, Orthopedic Physical Assessment (7th ed.), and Cook & Hegedus, Orthopedic Physical Examination Tests: An Evidence-Based Approach (2nd ed.).
Palpation of the medial tibial border
Procedure
Patient supine or seated. Run your fingers firmly along the inner (posteromedial) border of the tibia from the knee to the ankle, and note the length of any tender area.
Positive Finding
Tenderness along the inner border of the lower two-thirds of the tibia, spread over several centimetres rather than at one spot.
Interpretation
Diffuse tenderness along the border with exercise-related pain fits medial tibial stress syndrome. Tenderness at one small point, pain at rest or at night, or pain when hopping points to a tibial stress fracture and needs imaging. Pain with tightness and numbness during exercise that settles with rest suggests exertional compartment syndrome. Note: medial tibial stress syndrome is a clinical diagnosis based on characteristic exercise-induced pain along the posteromedial tibial border. No physical test has established diagnostic sensitivity/specificity.
Resisted plantarflexion test
Procedure
Ask the patient to push the foot down against resistance, and to perform single-leg heel raises.
Positive Finding
Pain along the inner tibial border during resisted plantarflexion.
Interpretation
Loads the muscles attached along the tibial border (soleus, tibialis posterior, flexor digitorum longus) and supports medial tibial stress syndrome. It does not separate it from a stress fracture.
Single-leg hop test for pain reproduction
Procedure
Ask the patient to hop on the affected leg several times.
Positive Finding
Pain at the inner tibia with hopping; note whether it is spread out or at one spot.
Interpretation
Diffuse pain with hopping fits medial tibial stress syndrome; sharp focal pain, or being unable to hop, raises concern for a stress fracture and needs imaging.
Dorsiflexion stretching of the calf and plantarflexors
Procedure
Passively dorsiflex the ankle with the knee straight and then bent, and ask about pain at the inner tibia.
Positive Finding
Pain along the inner tibial border at end of the stretch.
Interpretation
Suggests the attaching muscles contribute to the pain and guides stretching and loading. Not a diagnostic test.
Navicular drop test
Procedure
Patient seated with the foot flat and the subtalar joint in neutral. Mark the navicular tuberosity and measure its height from the floor, then measure again in relaxed standing. Compare sides.
Positive Finding
A larger drop than on the other side, showing more arch lowering in standing.
Interpretation
Measures foot pronation, which is one of several risk factors linked to medial tibial stress syndrome. It is not a diagnostic test. Note: the navicular drop test quantifies foot pronation as a risk factor; it is not a validated diagnostic test, and the previously cited source did not support the figures shown.
Resisted inversion (tibialis posterior strength test)
Procedure
Patient seated. Ask the patient to turn the foot inwards and down against your resistance, and compare with the other side.
Positive Finding
Pain along the inner tibia, or weakness compared with the other side.
Interpretation
Loads tibialis posterior, one of the muscles attached along the painful border. Weakness guides strengthening. Not a diagnostic test.
⚠ Red Flags
- •Severe unilateral swelling with skin changes suggesting compartment syndrome
- •Night pain unrelated to activity suggesting possible malignancy
- •Systemic symptoms (fever, weight loss, night sweats) suggesting infection or systemic disease
- •Inability to bear weight or severe neurovascular compromise
- •Symptoms following trauma with significant swelling suggesting stress fracture
- •Unilateral lower limb oedema with calf pain suggesting deep vein thrombosis
⚡ Yellow Flags
- •Excessive perfectionism or rigid training goals increasing injury risk
- •Catastrophising about injury or fear-avoidance preventing appropriate rehabilitation
- •Body image concerns driving excessive training despite pain
- •Lack of social support for modified training approach
- •History of eating disorder or disordered eating affecting tissue healing
- •Unrealistic return-to-sport expectations creating psychological distress
- •Secondary gain from injury status affecting motivation to rehabilitate
Osteopathic Techniques
Treatment is conservative: rest, ice and activity modification, with no set rest period. Arch-support orthoses sped recovery compared with sham inserts, and shockwave shows promise; stretching, braces and compression stockings have not shown benefit. No trials of osteopathic techniques were found.

Safety: MTSS is thought to be able to progress to a tibial stress fracture, although not every case does, and severe stress fractures may need surgery. Review pain that persists or worsens despite reducing load.

Region
Tibialis posterior and the deep calf
Technique
Rationale
Calf and lower-leg soft tissue is usually given alongside a loading or stretching programme.
How it's done & evidence
How it's done
Hands-on kneading, stroking and sustained pressure to the calf (gastrocnemius and soleus), the Achilles tendon and the peroneal and tibial muscles of the lower leg. In trials it was given alongside exercise, such as eccentric calf loading.

Region
Gastrocnemius-soleus (calf)
Technique
Rationale
Calf muscle energy technique to ease gastrocnemius-soleus tightness that limits ankle dorsiflexion.
How it's done, cautions & evidence
How it's done
The calf is taken to its barrier by dorsiflexing the ankle. The patient pushes the foot gently down, at about 10–20% effort, against resistance for 5–10 seconds, relaxes for 3–5 seconds, and the new barrier is taken up.
Cautions
Not used with an acute fracture, a joint infection or a bone malignancy; take care with severe osteoporosis or after surgery that limits muscle contraction. Use the least force needed: too much can tear a muscle or pull off a tendon, especially in older patients.
Evidence in Medial Tibial Stress Syndrome
Searched 25 Oct 2026: no trials. Winters 2013 (SR, 11 trials, all at high risk of bias): stretching and strengthening exercises, compression stockings, lower-leg braces and low-energy laser have not been proven effective, and no study was free enough of bias to recommend a treatment.
