Introduction

Foot and ankle disorders pose significant challenges to individuals, affecting their mobility, function, and overall well-being. Surgical interventions have emerged as crucial tools in the management of these conditions, aiming to alleviate pain, correct deformities, and restore normal foot and ankle function. Over the years, foot and ankle surgery has witnessed remarkable advancements, driven by a deeper understanding of the complex anatomy, biomechanics, and pathology of the lower extremities [1]. This comprehensive review aims to provide a thorough examination of the recent advances in foot and ankle surgery, encompassing a wide range of surgical techniques, emerging technologies, and clinical outcomes. By offering a comprehensive overview of these advancements, this article seeks to inform and guide clinicians, researchers, and healthcare professionals involved in the care of patients with foot and ankle disorders. The field of foot and ankle surgery has evolved significantly, with innovative surgical techniques being developed and refined to address specific conditions and pathologies. Procedures such as bunion surgery, ankle arthroscopy, Achilles tendon repair and reconstruction, ankle fusion, total ankle replacement, and plantar fascia release have undergone notable improvements, leading to better surgical outcomes and enhanced patient satisfaction [2-5]. In addition to surgical techniques, emerging technologies have played a pivotal role in revolutionizing foot and ankle surgery. Minimally invasive approaches, navigation systems, 3D printing, biologics, and robotics have opened up new possibilities for precise surgical planning, personalized interventions, and improved patient outcomes. These technologies have allowed surgeons to navigate intricate anatomical structures, enhance surgical accuracy, and tailor treatments to individual patients, ultimately optimizing surgical outcomes. Clinical outcomes and patient-reported measures are fundamental in evaluating the effectiveness and success of foot and ankle surgery [6-9]. By assessing patient satisfaction, postoperative pain levels, functional outcomes, and complication rates, researchers and clinicians gain valuable insights into the effectiveness of different surgical interventions. These outcomes not only guide decision-making but also inform the development of best practices and the refinement of surgical techniques. Rehabilitation and postoperative care play a crucial role in the comprehensive management of foot and ankle surgery. Physical therapy protocols, weight-bearing guidelines, and patient education are essential components of the recovery process, promoting optimal healing, functional restoration, and long-term success following surgery. Despite the remarkable advancements in foot and ankle surgery, challenges and opportunities for improvement persist [10,11]. Personalized medicine, advancements in implant design and biomaterials, and the integration of telemedicine and remote monitoring present exciting avenues for further enhancing surgical outcomes and patient care.

By providing a comprehensive review of the latest advancements in foot and ankle surgery, this article aims to equip clinicians and researchers with the knowledge and understanding necessary to deliver state-of-the-art care to patients [12,13]. By staying abreast of the rapidly evolving field, healthcare professionals can optimize patient outcomes, enhance surgical techniques, and improve the quality of life for individuals with foot and ankle disorders.

Surgical Techniques

Bunion surgery

Bunion surgery, also known as hallux valgus correction, involves the correction of a bony prominence at the base of the big toe. Surgical techniques may vary depending on the severity of the deformity and may involve osteotomy (cutting and realigning bones), soft tissue procedures, or a combination of both [14]. The goal is to realign the bones, alleviate pain, and improve toe alignment.

Ankle arthroscopy

Ankle arthroscopy is a minimally invasive surgical technique that allows for the visualization and treatment of various ankle conditions. Small incisions are made, and a thin camera (arthroscope) is inserted, enabling the surgeon to assess and treat problems such as loose bodies, inflamed tissues, cartilage damage, and ankle instability.

Achilles tendon repair and reconstruction

Achilles tendon repair and reconstruction are performed to address conditions such as Achilles tendon ruptures or chronic tendonitis. The procedure involves reattaching or reconstructing the damaged tendon, either through open surgery or minimally invasive techniques. The aim is to restore the integrity and function of the Achilles tendon.

Ankle fusion

Ankle fusion, also known as arthrodesis, is a surgical technique that aims to fuse the bones of the ankle joint. This procedure is commonly performed to alleviate pain and stabilize the ankle joint in cases of severe arthritis or joint deformity. The fusion eliminates the joint motion but can provide significant pain relief and improved function [15].

Total ankle replacement

Total ankle replacement, or ankle arthroplasty, involves the replacement of the damaged ankle joint with an artificial implant. This procedure is typically performed for end-stage ankle arthritis when conservative treatments are ineffective. Total ankle replacement aims to reduce pain, improve joint function, and preserve range of motion.

Plantar fascia release

Plantar fascia release is a surgical technique used to treat plantar fasciitis, a condition characterized by inflammation and pain in the plantar fascia ligament on the bottom of the foot. The procedure involves releasing or partially detaching the plantar fascia from the heel bone to relieve tension and reduce pain.

Osteotomies for foot deformities

Osteotomies involve cutting and realigning bones to correct foot deformities such as flatfoot (pes planus) or high arches (pes cavus). Different types of osteotomies are performed depending on the specific deformity, with the goal of improving foot alignment, function, and reducing associated symptoms.

Soft tissue procedures

Various soft tissue procedures can be performed to address conditions such as ligament tears, tendon injuries, or joint instability. These procedures may involve tendon transfers, ligament reconstructions, or soft tissue releases to restore stability, correct imbalances, and improve overall foot and ankle function. Each surgical technique is tailored to the specific foot and ankle condition, considering factors such as the patient's age, severity of the condition, and individual goals. The choice of technique may vary among surgeons, and advances in surgical instrumentation and technology continue to refine and improve these procedures, leading to enhanced patient outcomes and faster recovery times.
