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...
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.
Synarthrosis
An immobile...

Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering
  • Rehabilitation Science

Background:

  • Subjective outcome scores are commonly used to assess function after knee arthroplasty.
  • These scores can be influenced by factors like pain and the function of the contralateral limb, increasing score variability.
  • Increased score variability may necessitate larger changes to achieve clinical significance.

Purpose of the Study:

  • To investigate the relationships between Knee Society pain and function scores, range of motion (ROM), and objective functional force measures.
  • To compare these relationships for both the surgically treated and nonoperated limbs before and after knee arthroplasty.

Main Methods:

  • Thirty-six patients undergoing total or unicompartmental knee arthroplasty were assessed.
  • Knee Society pain and function scores were collected pre- and post-operatively (3 months).
  • A dual-force platform measured limb lift-up force during a stepping task pre- and post-operatively.

Main Results:

  • Pre-operatively, function scores correlated with pain scores, nonoperated limb force, and ROM.
  • Post-operatively, function scores correlated with pain scores but showed no significant correlation with objective functional measures or ROM.
  • Patient-reported function scores and objective functional force measures appear to provide distinct information regarding recovery.

Conclusions:

  • Patient-reported function scores after knee arthroplasty are influenced by pain and may not fully capture objective functional recovery.
  • Objective functional measures, such as limb force, provide complementary information to subjective scores.
  • Collecting both subjective patient-reported outcomes and objective functional measures is recommended for a comprehensive understanding of functional recovery post-knee arthroplasty.
