Knee Joint01:23

Knee Joint

1.6K
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...

Bones of the Lower Limb: Femur and Patella

2.3K
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...

Summary

Patellar tendon (PT) ruptures after total knee arthroplasty (TKA) are serious. Augmentation techniques significantly reduce complication rates from 63% to 25% for these knee extensor mechanism injuries.

Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering
  • Reconstructive Surgery

Background:

  • Patellar tendon (PT) rupture is a rare but severe complication following total knee arthroplasty (TKA).
  • These ruptures often occur acutely after TKA due to knee trauma, disrupting the extensor mechanism and causing significant functional deficits.

Purpose of the Study:

  • To provide a comprehensive overview of patellar tendon ruptures occurring after TKA.
  • To discuss various treatment options, including operative and nonoperative interventions.
  • To present recommendations for managing common PT injuries encountered post-TKA.

Main Methods:

  • Review of existing literature and clinical data on patellar tendon ruptures post-TKA.
  • Analysis of operative techniques based on injury acuity, location, and soft tissue status.
  • Evaluation of different augmentation strategies: autografts, allografts, synthetic grafts, and meshes.

Main Results:

  • Complete PT ruptures typically require repair or reconstruction, but complication rates remain high.
  • Operative intervention is the primary treatment, with nonoperative management reserved for specific cases.
  • Augmentation of repair significantly reduces complication rates from 63% to 25%.

Conclusions:

  • Despite advancements in treatment options like augmentation, outcomes for patellar tendon ruptures post-TKA are unpredictable, and complications are frequent.
  • There is a clear need for further research to improve treatment protocols and patient outcomes.
  • The article offers expert recommendations for managing diverse patellar tendon injuries following TKA.
