Bones of the Lower Limb: Femur and Patella01:16

Bones of the Lower Limb: Femur and Patella

9.1K
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...

Ankle Joint01:10

Ankle Joint

3.5K
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...

Knee Joint01:23

Knee Joint

3.7K
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...

Summary

Anchor-induced hip chondral damage can occur with or without penetration. Non-penetrating damage may be monitored, while penetrating damage requires anchor removal for better outcomes.

Area of Science:

  • Orthopedic Surgery
  • Hip Arthroscopy
  • Sports Medicine

Background:

  • Anchor-induced chondral damage is a potential complication of hip arthroscopy.
  • Understanding the outcomes of this specific injury is crucial for surgical technique refinement.

Purpose of the Study:

  • To investigate the clinical and radiographic outcomes of anchor-induced chondral damage in the hip.
  • To differentiate outcomes based on the presence or absence of frank chondral penetration.

Main Methods:

  • Multicenter retrospective case series.
  • Analysis of intra-operative findings, post-surgical clinical courses, and hip outcome scores.
  • Review of revision surgeries involving anchor removal.

Main Results:

  • Two cases of acetabular chondral deformation without penetration had successful outcomes.
  • One case of deformation progressed to penetration with clinical worsening.
  • Three revision surgeries for exposed anchors resulted in two clinical improvements and one total hip arthroplasty.

Conclusions:

  • Anchor-induced chondral deformation without penetration may be managed with monitoring and a low threshold for revision.
  • Chondral penetration necessitates immediate anchor removal.
  • Preventative strategies include careful portal selection, appropriate anchor choice, and meticulous surgical technique.
