Foot and Ankle Surgery
Research Guide
What is Foot and Ankle Surgery?
Foot and Ankle Surgery is the orthopedic subspecialty addressing the epidemiology, assessment, treatment, and long-term outcomes of ankle injuries and disorders, including sprains, chronic instability, osteochondral lesions, arthroplasty, and rehabilitation in sports medicine.
The field encompasses 73,869 published works on ankle-related conditions. Papers cover prevalence, risk factors, clinical management, and evidence-based strategies for conditions like ankle sprains and chronic instability. Standardized rating systems and kinematic measurements provide objective tools for evaluating foot and ankle function.
Topic Hierarchy
Research Sub-Topics
Ankle Sprain Epidemiology
This sub-topic examines the incidence, prevalence, risk factors, and mechanisms of ankle sprains in athletic and general populations. Researchers study epidemiological patterns, injury prevention strategies, and prognostic factors using cohort studies and meta-analyses.
Chronic Ankle Instability
This sub-topic investigates the pathomechanics, functional anatomy, and natural history of chronic ankle instability following recurrent sprains. Researchers explore biomechanical deficits, proprioceptive impairments, and sensorimotor control mechanisms.
Ankle Arthroplasty
This sub-topic covers total ankle replacement techniques, implant designs, surgical outcomes, and complications in end-stage ankle arthritis. Researchers compare arthroplasty to fusion, analyze survivorship rates, and evaluate patient-reported outcomes.
Osteochondral Lesions of the Talus
This sub-topic addresses the diagnosis, classification, and treatment of osteochondral defects in the talar dome, including cartilage repair techniques. Researchers study lesion staging, microfracture, autologous chondrocyte implantation, and graft outcomes.
Ankle Ligament Reconstruction
This sub-topic focuses on surgical techniques for lateral ligament repair and reconstruction in chronic instability cases. Researchers evaluate anatomic repairs, tendon grafts, outcomes, and return-to-sport criteria.
Why It Matters
Foot and Ankle Surgery guides clinical management of common sports injuries, with standardized rating systems enabling consistent outcome reporting across studies. Kitaoka et al. (1994) in "Clinical Rating Systems for the Ankle-Hindfoot, Midfoot, Hallux, and Lesser Toes" developed four systems incorporating subjective and objective factors for ankle-hindfoot, midfoot, hallux, and lesser toes, cited 4411 times for standardizing function, alignment, and pain assessments. Fong et al. (2007) in "A Systematic Review on Ankle Injury and Ankle Sprain in Sports" synthesized evidence on incidence and prevention, informing rehabilitation protocols in sports medicine. Hertel (2002) detailed functional anatomy and pathomechanics in "Functional Anatomy, Pathomechanics, and Pathophysiology of Lateral Ankle Instability," aiding surgical planning for ligament reconstruction. Kadaba et al. (1990) advanced gait analysis in "Measurement of lower extremity kinematics during level walking," supporting preoperative and postoperative evaluations with precise joint angle computations.
Reading Guide
Where to Start
"Clinical Rating Systems for the Ankle-Hindfoot, Midfoot, Hallux, and Lesser Toes" by Kitaoka et al. (1994) provides foundational standardized tools for clinical assessment, essential for understanding outcome reporting in foot and ankle surgery.
Key Papers Explained
Kitaoka et al. (1994) in "Clinical Rating Systems for the Ankle-Hindfoot, Midfoot, Hallux, and Lesser Toes" establishes rating scales for function and pain, which Hertel (2002) in "Functional Anatomy, Pathomechanics, and Pathophysiology of Lateral Ankle Instability" applies to instability pathomechanics. Fong et al. (2007) in "A Systematic Review on Ankle Injury and Ankle Sprain in Sports" builds on these by reviewing epidemiology, while Kadaba et al. (1990) in "Measurement of lower extremity kinematics during level walking" supplies kinematic methods to quantify pre- and post-surgical gait. Berg (1989) in "Measuring balance in the elderly: preliminary development of an instrument" complements with balance metrics relevant to rehabilitation.

Advanced Directions
Research continues on epidemiology and rehabilitation methods for ankle sprains and chronic instability, with keywords like ligament reconstruction and Ponseti method indicating focus areas. No recent preprints or news available, so frontiers rely on established high-citation works like those on osteochondral lesions and arthroplasty.

Frequently Asked Questions
What rating systems exist for evaluating ankle and foot clinical status?
The American Orthopaedic Foot and Ankle Society developed four rating systems for the ankle-hindfoot, midfoot, hallux, and lesser toes. These systems integrate subjective and objective factors into numerical scales assessing function, alignment, and pain. Kitaoka et al. (1994) detailed these in "Clinical Rating Systems for the Ankle-Hindfoot, Midfoot, Hallux, and Lesser Toes.".
How is lower extremity kinematics measured during walking?
A simple external marker system and algorithms compute joint angle motion using embedded axes and Euler rotation angles on video motion analysis systems like VICON. Kadaba et al. (1990) implemented this in "Measurement of lower extremity kinematics during level walking." The method supports precise gait analysis for foot and ankle disorders.
What is the functional anatomy related to lateral ankle instability?
Lateral ankle instability involves pathomechanics of acute sprains progressing to chronic states, with specific ligament and joint contributions. Hertel (2002) reviewed anatomy, pathomechanics, and pathophysiology in "Functional Anatomy, Pathomechanics, and Pathophysiology of Lateral Ankle Instability." Data sources included MEDLINE and CINAHL searches from 1982-2001.
What does research show about ankle injuries in sports?
A systematic review covers epidemiology, mechanisms, and prevention of ankle sprains in sports. Fong et al. (2007) compiled findings in "A Systematic Review on Ankle Injury and Ankle Sprain in Sports," cited 1422 times. It provides evidence for risk factors and management strategies.
How was balance measurement developed for the elderly?
An instrument for balance assessment in elderly individuals was created through surveys of 38 patients aged 60-93 and 32 professionals. Berg (1989) reported preliminary development in "Measuring balance in the elderly: preliminary development of an instrument." The tool targets clinical use in rehabilitation.
What are key factors in patellar instability relevant to ankle surgery?
Radiographic and CT analysis identified anatomic factors like trochlear dysplasia in 143 operated knees versus controls. Dejour et al. (1994) analyzed these in "Factors of patellar instability: An anatomic radiographic study." Findings inform related lower extremity instability assessments.
