Ankle Joint

3.4K
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
This summary is machine-generated.

Chronic ankle instability (CAI) affects athletes in sports like soccer and basketball, with recurrent sprains being most common. Further research is needed to understand the full extent of CAI in sports populations.

Area of Science:

  • Sports Medicine
  • Biomechanics
  • Orthopedics

Background:

  • Chronic ankle instability (CAI) refers to ankle joint complex insufficiencies after acute injury.
  • CAI aspects include perceived instability, mechanical instability, and recurrent sprains.
  • These issues are frequently reported in athletes following ankle sprains.

Purpose of the Study:

  • To identify and quantify common aspects of chronic ankle instability (CAI) within various individual sports.
  • To determine the prevalence of perceived instability, mechanical instability, and recurrent sprains in athletes.

Main Methods:

  • A systematic literature search was conducted across five major databases (MEDLINE, Web of Science, CINAHL, SPORTDiscus, AMED) up to October 2013.
  • 88 studies were included for review.
  • Weighted percentages of outcome data were calculated to compare CAI aspects across different sports.

Main Results:

  • Soccer, basketball, and volleyball showed the highest participation rates in studies on CAI.
  • Recurrent ankle sprain was the most frequently reported aspect of CAI.
  • Soccer players exhibited the highest rates of recurrent sprain (61%) and mechanical instability (38%), while track and field athletes had the highest perceived instability (41%). Gymnasts reported the most persistent symptoms post-sprain.

Conclusions:

  • This review highlights the prevalence of CAI aspects in sporting populations, with recurrent sprains being a significant issue.
  • Identified research limitations indicate a need for more controlled studies.
  • The true extent of chronic ankle instability across diverse sports remains unclear, necessitating further investigation.
