◐Partially SupportedMedial collateral ligament tears often occur with ACL tears and usually heal without surgery.

◐Partially SupportedThe FABER test assesses hip joint laxity or tightness by observing how far the knee flops down.

◐Partially SupportedChecking for pain during abdominal wall musculature tests can identify injuries where muscles attach to the pubic bone.

◐Partially SupportedHip arthritis or a labral tear can cause isolated knee pain due to neuroanatomy, potentially leading to misdiagnosis.

◐Partially SupportedPronated feet that cannot perform the windlass mechanism would lack spring, become painful, and lead to attenuation of the tendon on the inside.

◐Partially SupportedThe pivot shift test assesses knee stability by applying valgus stress and checking for a clunk as the iliotibial band moves forward.

◐Partially SupportedThe ability to touch toes, bend forward, lean back, twist, and bend sideways can be assessed during a standing exam to evaluate range of motion and identify pain.

◐Partially SupportedA common knee misdiagnosis stems from failing to perform a thorough physical exam, potentially overlooking patella issues when an ACL tear is suspected.

◐Partially SupportedEccentric loading of the foot helps tighten the sub-talar joint, making the foot rigid for propulsion.

◐Partially SupportedPain in the front of the hip during the Stingfield exam may indicate a hip flexor strain, whereas deep joint pain is less likely to cause tenderness in that specific area.

◐Partially SupportedWhen going up on toes, the heel should move into varus, and the formation of the arch indicates potential issues with the hip, knee, or ankle.

◐Partially SupportedThe KT arthrometer is a tolerable diagnostic tool even in acute knee injury situations when swelling prevents a physical exam.

◐Partially SupportedStress fractures of the tibia are characterized by point tenderness, whereas shin splints (medial tibial stress syndrome) present with more diffuse tenderness over a larger area.

◐Partially SupportedAssessing gait by observing walking at a normal pace is important for evaluating hip, knee, and ankle pain.

◐Partially SupportedHallux valgus can cause pain and lead to the second toe translating to accommodate the deviation.

◐Partially SupportedDynamic functional tests like two-leg and one-leg squats provide more information than basic gait analysis.

◐Partially SupportedArthritis of the first metatarsophalangeal joint is a common injury in runners.

◐Partially SupportedTenderness in the web space between the lesser toes can indicate a neuroma.

◐Partially SupportedTibialis anterior tendinitis can cause sudden, severe pain in the front of the ankle, sometimes mimicking intra-articular joint processes.

◐Partially SupportedAn intact Achilles tendon presents with a normal contour and is not swollen.

◐Partially SupportedSpeeding up gait can sometimes elicit pain or findings not apparent with a normal pace.

◐Partially SupportedA normal reciprocal gait pattern involves the arms moving in opposition to the legs.

◐Partially SupportedObserving trunk side-to-side leaning and weight shift over one extremity during gait can indicate issues.

◐Partially SupportedIncreasing stride length during a gait assessment can help identify hip pathology if it recreates pain.

◐Partially SupportedA squeaking tibialis anterior tendon indicates inflammation.

◐Partially SupportedPelvic tilting during a single-leg stance test may indicate hip abductor injury or a neurologic issue causing muscle under-activation.

◐Partially SupportedThe FADIR and Scour tests elicit pain by rotating the femoral head within the acetabulum, potentially indicating hip joint pathology.

◐Partially SupportedLurching during gait can be a potential problem with hip musculature, particularly the abductors.

◐Partially SupportedInjuries in the calf or back of the leg commonly occur at the musculotendinous junction of the gastrocnemius muscle.

◐Partially SupportedThe Lachman exam is the most sensitive clinical test for ACL tears.

◐Partially SupportedTurf toe is an acute injury to the ligaments on the bottom of the toe that can cause severe pain and swelling.

◐Partially SupportedTenderness and tendonitis of the toe flexor tendon in the posterior ankle can occur in dancers.

◐Partially SupportedThe Pez tendon area on the proximal tibia can be a source of pain due to bursitis or tendonitis.

◐Partially SupportedHyperextending the knee can help identify internal joint processes, fluid, meniscus tears, or acute ligament injuries.

◐Partially SupportedThe medial patellofemoral ligament stabilizes the kneecap, and apprehension during testing may indicate laxity.

◐Partially SupportedTesting abductor strength involves having the patient lift their leg and resisting downward pressure.

◐Partially SupportedPalpating the medial joint line of the knee can indicate meniscus tears or arthritis.

◐Partially SupportedInjecting lidocaine into the hip can help diagnose knee pain.

◐Partially SupportedHip pain can be a cause of knee pain.
