The knee joint joins the thigh with the leg and consists of two articulations: one between the femur and tibia, and one between the femur and patella. It is the largest joint in the human body and is very complicated. The knee is a mobile trocho-ginglymus (a pivotal hinge joint), which permits flexion and extension as well as a slight medial and lateral rotation. Since in humans the knee supports nearly the whole weight of the body, it is vulnerable to both acute injury and the development of osteoarthritis.

It is often grouped into tibiofemoral and patellofemoral components. (The fibular collateral ligament is often considered with tibiofemoral components.)

The knee is a hinge type synovial joint, which is composed of three functional compartments: the femoropatellar articulation consists of the patella, or "kneecap", and the patellar groove on the front of the femur through which it slides; and the medial and lateral femorotibial articulations linking the femur, or thigh bone, with the tibia, the main bone of the lower leg. The joint is bathed in synovial fluid which is contained inside the synovial membrane called the joint capsule. The posterolateral corner of the knee is an area that has recently been the subject of renewed scrutiny and research.

James William "Jimmy" Buffett (born December 25, 1946) is an American singer–songwriter, film producer, businessman, and author. He is best known for his music, which often portrays an "island escapism" lifestyle. Together with his Coral Reefer Band, Buffett has recorded hit songs including "Margaritaville" (ranked 234th on the Recording Industry Association of America's list of "Songs of the Century"), and "Come Monday". He has a devoted base of fans known as "Parrotheads".

Aside from his career in music, Buffett is also a best-selling writer and is involved in two restaurant chains named after two of his best known songs, "Cheeseburger in Paradise" and "Margaritaville". He owns the Margaritaville Cafe restaurant chain and co-developed the Cheeseburger in Paradise restaurant concept with OSI Restaurant Partners (parent of Outback Steakhouse), which operates the chain under a licensing agreement with Buffett.

Buffett spent part of his childhood in Mobile, Alabama. In grade school years, he attended St. Ignatius School, where he played the trombone in the school band. He later lived in Fairhope, Alabama, mentioned by himself as his "Home Town" during a 2001 concert. He graduated high school from McGill Institute for Boys (now McGill-Toolen Catholic High School) in 1964. He began playing guitar during his college years at Pearl River Community College, The University of Southern Mississippi in Hattiesburg, Mississippi, and Auburn University where he received a bachelor's degree in journalism in 1969. He was initiated into the fraternity Kappa Sigma (ΚΣ) at the University of Southern Mississippi. After graduating from college, Buffett worked as a correspondent for Billboard magazine in Nashville, breaking the news of the separation of Flatt and Scruggs.
