What is an ACL (Anterior Cruciate Ligament) Tear?
An anterior cruciate ligament (ACL) tear is a severe knee injury involving rupture of the primary stabilizing ligament controlling anterior tibial translation, often accompanied by an audible pop and knee giving way.
What is Arthroscopy?
Arthroscopy is a minimally invasive surgical procedure where a miniature camera (arthroscope) is inserted into a joint through small incisions to diagnose and repair cartilage, meniscus, and ligament injuries.
What is Articular Cartilage?
Articular cartilage is a smooth, glass-like connective tissue covering bone ends in joints. It eliminates friction and cushions impact during physical movements.
What is Bursitis?
Bursitis is the painful inflammation of one or more bursae—small, fluid-filled sacs that cushion the bones, tendons, and muscles near joints, commonly affecting the shoulder, elbow, hip, or knee.
What is Carpal Tunnel Syndrome?
Carpal tunnel syndrome is a peripheral nerve entrapment neuropathy caused by compression of the median nerve within the carpal tunnel of the wrist, producing numbness, tingling, and weakness in the thumb and index fingers.
What is Coxarthrosis (Hip Osteoarthritis)?
Coxarthrosis is progressive osteoarthritis of the hip joint characterized by gradual wear of articular cartilage, joint space narrowing, groin pain, and restricted mobility.
What is Cubital Tunnel Syndrome (Ulnar Nerve Entrapment)?
Cubital tunnel syndrome is an ulnar nerve entrapment at the inside edge of the elbow, causing tingling, numbness, and motor weakness in the ring and little fingers.
What is a Joint Dislocation?
A joint dislocation is an orthopedic emergency occurring when the articulating ends of two connected bones are completely forced out of their normal anatomical positions, disrupting stabilizing ligaments.
What is Femoroacetabular Impingement (FAI)?
Femoroacetabular impingement (FAI) is a hip condition where bone overgrowths on the femoral head (cam) or acetabular rim (pincer) cause abnormal friction, damaging the labrum and articular cartilage.
What is Flatfoot (Pes Planus)?
Flatfoot (pes planus) is a postural deformity where the medial longitudinal arch of the foot collapses, causing the entire sole to make nearly complete contact with the ground.
What is a Ganglion Cyst?
A ganglion cyst is a noncancerous lump that develops along the tendons or joints of wrists and hands, filled with a thick, jelly-like lubricating synovial fluid.
What is Gouty Arthritis and Hyperuricemia?
Gouty arthritis is a painful metabolic form of inflammatory arthritis triggered by hyperuricemia, where monosodium urate crystals precipitate in joints, most frequently targeting the great toe.
What is Hallux Valgus (Bunion)?
Hallux valgus, commonly known as a bunion, is a progressive foot deformity where the big toe deviates laterally toward the second toe, creating a painful bony bump at the metatarsophalangeal joint.
What is a Joint?
A joint is the anatomical junction connecting two or more bones, enabling movement and mechanical support. It consists of cartilage, synovial fluid, ligaments, and tendons working as an integrated unit.
What is a Jones Fracture?
A Jones fracture is a specific break occurring at the base of the fifth metatarsal bone on the outer edge of the foot, known for prolonged healing times due to restricted blood supply in this watershed zone.
What is a Ligament?
A ligament is a tough band of fibrous connective tissue that connects two bones together at a joint, providing passive mechanical stability and preventing abnormal joint motions.
What is a Meniscus Tear?
A meniscus tear is a common knee injury involving damage to the C-shaped fibrocartilage discs that act as shock absorbers between the femur and tibia, caused by forceful twisting or degenerative tissue loss.
What is Nerve Entrapment?
Nerve entrapment is a condition where surrounding bones, cartilage, or tendons exert excessive pressure on a peripheral nerve, impairing conduction and causing numbness, tingling, and weakness.
What is Osteoporosis?
Osteoporosis is a metabolic bone disease marked by reduced bone mass and structural deterioration of bone tissue, making bones fragile and highly susceptible to low-energy fragility fractures.
What is Patellofemoral Pain Syndrome (Runner's Knee)?
Patellofemoral pain syndrome (runner's knee) is an overuse condition characterized by pain around or behind the kneecap (patella), exacerbated by stair climbing, squatting, or prolonged sitting.
What is Peripheral Neuropathy?
Peripheral neuropathy refers to damage or dysfunction of the peripheral nerves that communicate between the central nervous system and limbs, causing weakness, burning pain, and numbness in the hands and feet.
What is Rheumatoid Arthritis?
Rheumatoid arthritis is a chronic autoimmune condition where the immune system attacks the joint synovium, leading to symmetrical joint swelling, morning stiffness exceeding 30 minutes, and progressive cartilage degradation.
What is Shockwave Therapy (ESWT)?
Extracorporeal shockwave therapy (ESWT) is a non-invasive orthopedic treatment utilizing high-energy acoustic pressure waves to stimulate microcirculation, accelerate tissue repair, and resolve chronic tendinopathies.
What is the Skeletal System?
The skeletal system is the foundational organ system composed of 206 bones, associated joints, cartilage, and ligaments that provides structural framework, protects vital organs, and enables locomotion.
What is a Soft Tissue Injury?
A soft tissue injury involves acute trauma or microtrauma to muscles, ligaments, tendons, or fascia, resulting in pain, swelling, hematoma formation, and localized inflammation.
What is a Sprain and Strain?
A sprain is a stretch or tear of ligaments supporting a joint, whereas a strain is an injury to muscle fibers or tendons from excessive stretching or forceful contraction.
What is Subacromial Impingement Syndrome?
Subacromial impingement syndrome is a common shoulder condition where rotator cuff tendons and the subacromial bursa become compressed beneath the acromion during overhead arm movements.
What is Synovial Fluid?
Synovial fluid is a viscous fluid rich in hyaluronic acid filling joint cavities. It acts as a biological lubricant reducing friction and nourishing articular cartilage.
What is a Tendon?
A tendon is a robust fibrous band of dense collagen connective tissue that anchors muscles to bones, transmitting muscular contractive force to produce skeletal joint motion.
What is a Vertebra?
A vertebra is an individual irregular bone within the vertebral column (spine); separated by intervertebral discs, these 33 bones encase the spinal cord and support vertical mechanical load.
