Functional Classification of Joints01:09

Functional Classification of Joints

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses  or amphiarthroses, whereas all synovial joints are classified as diarthroses.

Knee Joint01:23

Knee Joint

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 group...
Ankle Joint01:10

Ankle Joint

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...

Summary

Dual-mobility acetabular components (DMCs) show a lower dislocation risk in high-risk total hip arthroplasty patients compared to single-mobility (SM) components. This study found no increased risk of complications or revisions with DMCs.

Area of Science:

  • Orthopedic Surgery
  • Biomaterials Engineering

Background:

  • The efficacy of dual-mobility acetabular components (DMCs) in primary total hip arthroplasties (THAs) remains debated.
  • Single-mobility (SM) components are standard, but DMCs are considered for high-risk patients.

Purpose of the Study:

  • To compare dislocation and complication rates between DMCs and SM components in primary elective THAs.
  • To evaluate revision rates and survival outcomes for both acetabular component types.

Main Methods:

  • Retrospective analysis of 1,940 primary THAs (2010-2019) using cementless DMCs or SM components.
  • DMCs were indicated for patients >70 years or high dislocation risk; SM components for others.
  • Data on complications, revisions, and survival were collected and analyzed.

Main Results:

  • Fewer dislocations occurred in the DMC group (0.17%) compared to the SM group (1%) (p=0.019).
  • Overall complication rates were similar (5.1% DMC vs. 6.7% SM; p=0.214), with no DMC-specific issues.
  • Revision rates (1.6% DMC vs. 1.9% SM; p=0.709) and 5-year aseptic revision-free survival (98% DMC vs. 97.3% SM; p=0.780) were comparable.

Conclusions:

  • Monobloc DMCs demonstrated a reduced dislocation risk in high-risk THA patients versus SM components in low-risk patients at mid-term follow-up.
  • No significant increase in component-specific complications or revisions was observed with DMCs in this large cohort.
