Fractures: Bone Repair01:27

Fractures: Bone Repair

Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
Relaxation of Skeletal Muscles01:29

Relaxation of Skeletal Muscles

The period of muscle contraction primarily influences the duration of stimulation at the neuromuscular junction (NMJ), the presence of free calcium ions in the sarcoplasm, and the availability of energy or ATP to support contractions.
When an action potential reaches the axon terminal, it depolarizes the membrane and opens voltage-gated sodium channels. Sodium ions enter the cell, further depolarizing the presynaptic membrane. This depolarization causes voltage-gated calcium channels to open.
Flexural Stress01:16

Flexural Stress

When analyzing bending in symmetric members, it's crucial to understand how stresses distribute when subjected to bending moments. This stress distribution is effectively described by applying fundamental mechanics and material science principles, particularly Hooke's Law for elastic materials.
Hooke's Law states that within the material's elastic limits, stress is directly proportional to strain. In a member experiencing a bending moment, the strain at any point is relative to its distance...
Unsymmetric Bending - Angle of Neutral Axis01:15

Unsymmetric Bending - Angle of Neutral Axis

Unsymmetrical bending occurs when a structural member is subjected to bending moments in a plane that does not align with the member's principal axes. This scenario typically arises in beams and other structural components when loads are applied at non-ideal angles, introducing complexities in stress analysis.
When a bending moment is applied at an angle θ concerning the vertical axis of a symmetrical member, it can be resolved into components along the member's principal centroidal axes. The...
Muscle Coordination and Action01:24

Muscle Coordination and Action

Muscle coordination is a complex and finely tuned process essential for smooth and purposeful movements like flexion, extension, adduction, abduction, and rotation. The human body orchestrates the actions of various muscles working in concert, each with a specific role. Four functional types describe how muscles work together: agonist, antagonist, synergist, and fixator.
Agonists
Agonist muscles, often called prime movers, are the primary muscles responsible for producing a specific movement.
Somatic Spinal Reflexes01:22

Somatic Spinal Reflexes

Somatic spinal reflexes are rapid, involuntary muscular responses to external stimuli that involve the somatic musculature and the spinal cord.
One of the most well-known somatic spinal reflexes is the stretch reflex, which is activated by the sudden stretching of a muscle. This reflex involves the activation of specialized sensory receptors called muscle spindles, which are located in the muscle tissue and detect changes in the length and speed of muscle contractions. When a muscle is suddenly...

Summary
This summary is machine-generated.

Flexion contractures after total knee arthroplasty (TKA) can be managed with perioperative and intraoperative strategies. Achieving a post-operative flexion contracture of less than 15 degrees is the primary goal for successful TKA outcomes.

Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering
  • Rehabilitation Medicine

Background:

  • Flexion contractures are a common complication following total knee arthroplasty (TKA).
  • These contractures can significantly impact patient function and satisfaction.
  • Identifying causative factors and effective management strategies is crucial for TKA success.

Purpose of the Study:

  • To review the factors contributing to flexion contractures after TKA.
  • To outline the goals and methods for correcting knee flexion contractures.
  • To discuss perioperative and intraoperative interventions for managing TKA-related flexion contractures.

Main Methods:

  • Review of literature on TKA flexion contractures.
  • Analysis of treatment strategies, including intraoperative correction and postoperative management.
  • Discussion of specific considerations for inflammatory cases with severe contractures.

Main Results:

  • The primary goal for TKA flexion contracture correction is < 15 degrees.
  • Contractures ≤ 10 degrees are typically asymptomatic, while 10-15 degrees may persist symptomatically.
  • Intraoperative correction is key, except in inflammatory cases (>40 degrees), where partial correction followed by physical therapy and splinting is effective.

Conclusions:

  • Effective management of TKA flexion contractures involves a combination of perioperative and intraoperative techniques.
  • Achieving optimal knee range of motion post-TKA requires careful attention to contracture correction.
  • Specific protocols are necessary for severe or inflammatory cases to ensure favorable long-term outcomes.
