Knee Joint01:23

Knee Joint

3.4K
The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris...

Mitral Valve Prolapse I: Introduction

1.1K
IntroductionThe mitral valve, one of the heart's four valves, regulates blood flow. These valves have flaps that open and close to direct blood properly through the heart and body. During each heartbeat, the flaps open for blood to pass through and seal shut to prevent backflow. Specifically, the mitral valve opens to allow blood flow from the heart's upper left chamber to the lower left chamber. It then closes securely as the lower left chamber contracts to pump blood to the body, preventing...

Bones of the Lower Limb: Femur and Patella01:16

Bones of the Lower Limb: Femur and Patella

8.2K
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the...

Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering
  • Sports Medicine

Background:

  • The menisci are vital fibrocartilaginous structures in the knee joint.
  • Meniscectomy (meniscus removal) is frequently linked to the development of arthritic changes over time.
  • The menisci perform critical functions including load bearing, shock absorption, and joint stability.

Purpose of the Study:

  • To emphasize the importance of preserving meniscal tissue during knee surgery.
  • To review diagnostic accuracy of clinical examination versus imaging for meniscal injuries.
  • To outline current surgical techniques for meniscal repair and transplantation.

Main Methods:

  • Review of long-term follow-up studies on meniscectomized knees.
  • Comparison of clinical examination accuracy with magnetic resonance imaging (MRI) for meniscal injury diagnosis.
  • Description of evolving surgical techniques: open, arthroscopic (inside-out, outside-in), and all-inside repairs, and meniscal transplantation.

Main Results:

  • Virtually all meniscectomized knees exhibit arthritic changes with time.
  • Clinical examination by a skilled surgeon is as accurate as MRI for diagnosing meniscal injuries.
  • Various arthroscopic techniques have advanced meniscal repair, and transplantation is viable for select patients.

Conclusions:

  • Meniscal preservation is paramount due to the structure's essential knee functions.
  • Accurate diagnosis of meniscal injuries can be achieved through clinical examination.
  • Surgical interventions, including repair and transplantation, offer solutions for meniscal damage and loss.
