Spring 2014 EXSC 201-01 BONY ANATOMY OF THE KNEE See Chapter 20 Pgs 557, 562-563 1. Describe bones of the knee complex. 2. Identify common and unique characteristics of the tibiofemoral joint. Prentice, W. (2014). Principles of athletic training: A competency-based approach. (15th ed.). New York: McGraw-Hill.
Spring 2014 EXSC 201-01 Femur • the longest & largest bone in body • articulates with innominate, tibia and patella o innominate = ilium, ischium & pubis 2
Spring 2014 EXSC 201-01 Tibia • largest, weight-bearing, bone of lower leg • upper end of bone widens to form two condyles o articulates with femur and bears weight translated from it 3
Spring 2014 EXSC 201-01 4 Patella • flat, triangular-shaped • posterior surface articulates with the femur
Spring 2014 EXSC 201-01 5 Patella • Sesamoid bone - oval-shaped bone imbedded within a tendon • function includes 1. 2. 3. to protect femoral condyles from a direct blow, to protects quadriceps tendon from friction against femur, and to improve mechanical advantage of quadriceps
Spring 2014 EXSC 201-01 6 Joints of the Knee 1. Tibiofemoral Joint 2. Patellofemoral Joint The fibula does not articulate with the femur or patella; it is not directly involved in weight transmission.
Spring 2014 EXSC 201-01 7 Osteokinematic vs. Arthrokinematic • Osteo - gross movement of bones at joints; the way in which bones move in space without regard for joint surfaces o Tibiofemoral Joint is classified as a hinge joint with two motions, flexion and extension • Arthro - small amplitude motions of bones at joint surface; the way in which adjoining joint surfaces move in relation to each other o Rolling and gliding occur at the Tibiofemoral joint
Spring 2014 EXSC 201-01 8 Tibiofemoral Roll & Glide When the concave surface is fixed and the convex surface moves on it, the convex surface rolls and glides in opposite directions. Femur convex concave Tibia If glide didn’t accompany the roll, some areas would gap and some would pinch. To preserve joint integrity, roll and glide must occur together
Spring 2014 EXSC 201-01 9 “Screw-Home” Mechanism Tibiofemoral joint is classified as a hinge joint with motions of extension and flexion, but rotation also occurs: with extension, lateral rotation of tibia occurs
Spring 2014 EXSC 201-01 “Screw-Home” Mechanism, cont. • medial condyle of the tibia is larger than lateral • as knee extends, medial condyle slides forward on femur, forcing lateral rotation of tibia on femur 10
Spring 2014 EXSC 201-01 11 “Screw-Home” Mechanism rotation that occurs at tibiofemoral joint as it moves from flexion into extension rotation of tibia on femur helps stabilize knee joint when in full extension
Spring 2014 EXSC 202-01 12 Homework 1. Read Functional Anatomy (of the Knee) on pages 562-563.
