Ankle & Foot
Sprain / Ligament
Lateral Ankle Sprain
Injury of the lateral ankle ligament complex, most commonly the ATFL, often after inversion with plantar flexion.
Open clinical guideRupture / Tendon
Achilles Tendon Rupture
Partial or complete rupture of the Achilles tendon, commonly presenting with sudden posterior-ankle pain and loss of plantar-flexion function.
Open clinical guideFascia / Overuse
Plantar Heel Pain (Plantar Fasciopathy)
Plantar-medial heel pain often worst with first steps after rest.
Open clinical guideTendinopathy / Overuse
Achilles Tendinopathy
Load-related midportion or insertional Achilles tendon pain and impaired function.
Open clinical guideTendinopathy / Foot
Posterior Tibial Tendon Dysfunction (Progressive Collapsing Foot Deformity)
Medial ankle tendon pain and possible progressive acquired foot deformity.
Open clinical guideKnee
Sprain / Tear
Anterior Cruciate Ligament (ACL) Injury
Partial or complete ACL disruption causing rotational and anterior knee instability, often during pivoting, deceleration or awkward landing.
Open clinical guideMeniscus / Cartilage
Meniscal Injury
Traumatic or degenerative injury of the medial or lateral meniscus, presenting with joint-line pain, swelling and sometimes catching or locking.
Open clinical guideArthritis / Degenerative
Knee Osteoarthritis
Clinical osteoarthritis causing activity-related knee pain, stiffness and functional limitation; exercise and education are core treatments.
Open clinical guidePatellofemoral / Load-Related
Patellofemoral Pain
Peripatellar pain aggravated by loaded knee flexion such as stairs, squatting and running.
Open clinical guideTendinopathy / Overuse
Patellar Tendinopathy
Load-related inferior patellar tendon pain, often in jumping athletes.
Open clinical guideSprain / Ligament
Posterior Cruciate Ligament (PCL) Injury
Posterior cruciate ligament injury causing posterior tibial laxity after trauma.
Open clinical guideSprain / Ligament
Medial Collateral Ligament (MCL) Injury
Valgus-related medial knee ligament injury, often managed non-operatively when isolated.
Open clinical guideShoulder
Tendinopathy / Impingement
Rotator Cuff Tendinopathy / Subacromial Pain
Load-related rotator cuff pain, often aggravated by elevation and overhead activity; modern management emphasizes active rehabilitation rather than a purely mechanical 'impingement' model.
Open clinical guideTear / Rupture
Full-Thickness Rotator Cuff Tear
Complete disruption through the tendon thickness, ranging from degenerative tears with preserved function to acute traumatic tears with major weakness.
Open clinical guideInstability / Subluxation
Anterior Shoulder Instability
Recurrent or traumatic tendency of the humeral head to translate anteriorly, often after dislocation or subluxation.
Open clinical guideCapsular / Stiffness
Adhesive Capsulitis (Frozen Shoulder)
Painful global restriction of active and passive glenohumeral movement, commonly greatest in external rotation.
Open clinical guideSprain / Ligament
Acromioclavicular (AC) Joint Injury
AC and sometimes coracoclavicular ligament injury, commonly after direct shoulder impact.
Open clinical guideTendinopathy / Overuse
Long-Head Biceps Tendinopathy
Anterior shoulder pain associated with long-head biceps loading, often coexisting with cuff or labral pathology.
Open clinical guideHip & Groin
Impingement / Joint
Femoroacetabular Impingement Syndrome (FAIS)
Symptomatic nonarthritic hip condition involving motion-related hip/groin pain with clinical findings and cam/pincer morphology when imaging is relevant.
Open clinical guideArthritis / Degenerative
Hip Osteoarthritis
Hip OA commonly causes groin/anterior thigh pain, mobility loss and reduced walking function; rehabilitation emphasizes exercise, education and selected manual therapy.
Open clinical guideTendinopathy / Lateral Hip Pain
Greater Trochanteric Pain Syndrome (GTPS)
Lateral hip pain commonly associated with gluteal tendon pathology and compression sensitivity.
Open clinical guideTendinopathy / Overuse
Gluteal Tendinopathy
Load-related gluteus medius/minimus tendon pain with lateral hip symptoms.
Open clinical guideMuscle / Tendon Overuse
Adductor-Related Groin Pain
Groin pain associated with adductor loading, common in cutting and kicking sports.
Open clinical guideNeck & Upper Quarter
Nerve / Compression
Cervical Radiculopathy
Cervical nerve-root disorder causing neck/arm pain with sensory, motor or reflex changes in a root distribution.
Open clinical guideSpinal / Mechanical Pain
Mechanical Neck Pain
Movement- and load-related neck pain requiring neurological and serious-pathology screening.
Open clinical guideTraumatic / Whiplash
Whiplash-Associated Disorder (WAD)
Neck symptoms after acceleration–deceleration trauma; grade and screen for associated injury.
Open clinical guideWrist & Hand
Nerve / Compression
Carpal Tunnel Syndrome
Median nerve compression at the carpal tunnel causing nocturnal paresthesia, sensory symptoms and sometimes thenar weakness.
Open clinical guideTendon / Overuse
De Quervain Tenosynovitis
First dorsal compartment tendon disorder causing radial wrist pain with thumb use.
Open clinical guideTendon / Stenosis
Trigger Finger (Stenosing Flexor Tenosynovitis)
Flexor tendon gliding disorder causing painful clicking, catching or locking of a digit.
Open clinical guideElbow & Forearm
Tendinopathy / Overuse
Lateral Epicondylalgia (Tennis Elbow)
Load-related lateral elbow pain involving the common wrist-extensor tendon, especially extensor carpi radialis brevis.
Open clinical guideTendinopathy / Overuse
Medial Epicondylalgia (Golfer's Elbow)
Load-related pain at the common flexor-pronator tendon origin.
Open clinical guideSpine
Spinal / Mechanical Pain
Non-Specific Low Back Pain
Low back pain without identified serious specific pathology; function, education and activity are central.
Open clinical guideNerve / Radicular
Lumbar Radiculopathy
Lumbar nerve-root disorder with radiating leg pain and possible neurological deficit.
Open clinical guideSpinal / Mechanical Pain
Thoracic Spine Pain
Thoracic pain requiring consideration of mechanical, cardiopulmonary, visceral and fracture causes.
Open clinical guideClinical safety note
These guides are educational. Special tests do not diagnose a condition in isolation. Mechanism, history, neurologic/vascular screening, red flags, examination findings and appropriate imaging or referral must be integrated before treatment.
