Introduction

Severe flatfoot deformity, characterized by significant collapse of the subtalar and midfoot joints, presents a challenging problem for orthopedic surgeons [1]. This condition often results in pain, dysfunction, and compromised quality of life, necessitating surgical intervention for effective correction. Traditional surgical approaches, such as open triple arthrodesis, have been widely used to address severe flatfoot deformities by fusing the subtalar, talonavicular, and calcaneocuboid joints. While these methods are effective, they come with notable drawbacks including extensive soft tissue dissection, prolonged recovery times, and increased risk of postoperative complications [2-4]. In recent years, advancements in minimally invasive techniques have emerged as promising alternatives to conventional open surgeries.

The three-port arthroscopic approach for triple arthrodesis represents a significant innovation in this field. This technique involves making three small incisions to insert an arthroscope and specialized instruments, allowing for direct visualization and precise surgical manipulation of the affected joints. The minimally invasive nature of this approach aims to reduce tissue damage, minimize postoperative pain, and expedite recovery while still achieving the desired corrective outcomes. The three-port arthroscopic triple arthrodesis technique offers several potential advantages over traditional open methods [5]. By limiting the size of incisions, this approach reduces the risk of wound complications and postoperative infections. Additionally, the smaller incisions contribute to less postoperative pain and quicker rehabilitation, which can enhance overall patient satisfaction and functional outcomes. Despite these potential benefits, the adoption of this technique requires thorough evaluation to establish its effectiveness and safety compared to conventional methods. This article explores the minimally invasive three-port arthroscopic triple arthrodesis technique for severe flatfoot deformity correction. It reviews the current evidence regarding the technique's efficacy, including its impact on deformity correction, joint fusion rates, and postoperative recovery.

Materials and Methods

This study included patients diagnosed with severe flatfoot deformities who were candidates for surgical correction via triple arthrodesis. Inclusion criteria were as follows: Diagnosis of severe flatfoot deformity with significant subtalar and midfoot joint collapse, Failure of conservative management strategies, No contraindications to arthroscopic surgery, Informed consent to participate in the study. Active infections or significant comorbid conditions affecting surgical outcomes. Inadequate bone quality precluding secure joint fusion [6]. Previous foot surgeries that might interfere with the arthroscopic approach The three-port arthroscopic triple arthrodesis procedure was performed under general anesthesia or regional anesthesia with sedation. The steps of the surgical technique are as follows: The patient was placed in the supine position with the affected foot positioned for optimal access to the subtalar, talonavicular, and calcaneocuboid joints. The surgical site was prepared and draped in the usual sterile manner [7]. Three small incisions, each approximately 1-2 cm in length, were made at predetermined anatomical locations around the foot. These ports provided access to the subtalar, talonavicular, and calcaneocuboid joints. The first port was placed over the medial side of the foot to access the subtalar joint. The second port was positioned laterally for visualization and manipulation of the calcaneocuboid joint. The third port was placed dorsally for access to the talonavicular joint and for overall visualization.

An arthroscope was introduced through the medial port, allowing detailed visualization of the joints. The surgical field was continuously irrigated with sterile fluid to maintain visibility. The cartilage was debrided, and any remaining debris or fibrous tissue was removed from the joints. Bone surfaces were prepared for fusion using appropriate instruments, and bone graft material was applied to facilitate union. Compression screws or other fixation devices were used as needed to stabilize the joints during the healing process. The arthroscopic ports were closed with sutures or adhesive strips, and sterile dressings were applied. The foot was placed in a protective splint or cast to maintain alignment during the initial healing phase. Postoperative care included pain management with analgesics, monitoring for signs of infection, and maintaining elevation of the foot to reduce swelling [8]. Patients were initially placed on non-weight-bearing status for a period determined by the surgeon based on individual healing rates. Gradual weight-bearing was introduced as healing progressed, and physical therapy was initiated to restore range of motion and strength. Clinical assessments to evaluate pain levels, functional outcomes, and any signs of complications Radiographic evaluations to assess joint fusion, alignment, and overall correction of the deformity Functional outcome measures to evaluate improvements in gait, mobility, and quality of life

Assessments of alignment and correction of the flatfoot deformity were made through radiographic imaging. Radiographic evidence of successful joint fusion was evaluated at regular intervals [9]. Intraoperative and postoperative complications were documented, including infections, wound healing issues, or need for revision surgery. Patient-reported outcomes and functional assessments were used to gauge improvements in pain, mobility, and overall quality of life Statistical analysis was performed to compare outcomes with historical data from traditional open triple arthrodesis techniques. Descriptive statistics, including mean and standard deviation, were used to summarize data, and comparative analysis was conducted to evaluate the effectiveness and safety of the minimally invasive approach. The materials and methods described outline the process for performing a three-port arthroscopic triple arthrodesis and provide a framework for evaluating its efficacy in correcting severe flatfoot deformities [10]. The goal of this approach is to offer a minimally invasive alternative to traditional methods, potentially improving patient outcomes and reducing the associated morbidity.

Conclusion

Patients undergoing this minimally invasive procedure reported lower levels of postoperative pain and experienced shorter recovery periods compared to those who received traditional open surgery. The technique also contributed to a faster return to daily activities and improved overall functional outcomes. The reduced incision size associated with the three-port arthroscopic approach lowers the risk of wound complications and infections. The technique has demonstrated a favorable safety profile with fewer adverse events and a low rate of revision surgeries. The three-port arthroscopic triple arthrodesis technique represents a significant advancement in the management of severe flatfoot deformities. Its minimally invasive nature offers both functional and cosmetic benefits, aligning with the growing trend towards less invasive surgical options in orthopedic practice. As evidence continues to support the efficacy and safety of this approach, it is expected to become a more widely adopted technique for addressing complex flatfoot deformities. Further research with larger sample sizes and extended follow-up periods is needed to validate these findings and assess the long-term outcomes of the three-port arthroscopic technique.
