Abstract
Neuropathic (Charcot) arthropathy is a progressive degenerative condition that leads to the destruction and collapse of weight bearing joints, often accompanied by large effusions that compromise supporting soft tissue structures. Historically, neurosyphilis was the primary cause, but today, poorly controlled diabetes mellitus is the most common underlying factor. Total Knee Arthroplasty (TKA) was considered a contraindication in neuropathic arthropathy due to the risk of complications such as periprosthetic joint infection, tibiofemoral dislocation, and periprosthetic fracture. However, recent studies suggest that using constrained implants, along with advanced surgical techniques, provide improved functional outcomes in this challenging patient population.
This study aims to evaluate the functional outcomes and complication rates of TKA with constrained prostheses in patients with neuropathic arthropathy, addressing the gap in existing literature that is primarily based on older techniques, small sample sizes and a short follow up period. Data of 25 patients from 2018-2023 who have undergone TKA with constrained implants and with inclusion and exclusion criteria will be collected. Primary outcomes, i.e., range of motion (ROM) and pain scores, will be assessed using paired t-tests, while the Kaplan-Meier method will estimate implant survival. Secondary outcomes, i.e., functional scores and complication rates, will be analyzed with descriptive and inferential statistics.
Results of existing studies indicate that while constrained prostheses offer good functional outcomes, they are associated with a high rate of complications. These results highlight the need for careful patient selection and personalized treatment strategies. Future research should focus on larger sample sizes and long-term follow-up studies to refine patient selection criteria, improve surgical planning, and explore innovative implant designs to minimize complications. This study could contribute to the advancement of clinical knowledge and may influence treatment guidelines for managing neuropathic arthropathy, potentially improving patient outcomes and surgical decision-making.
Keywords: Neuropathic arthropathy, Charcot joint, total knee arthroplasty, constrained implants, functional outcomes, complication rates.
Background and Rationale
Neuropathic (Charcot) arthropathy is a progressive degenerative process leading to the destruction and collapse of the weight-bearing surface of joints, as well as the formation of large effusions that stretch supporting soft-tissue structures [1]. Historically, the primary underlying reason for loss of nociception was neurosyphilis. Today the most common cause of Neuropathy is long-standing and poorly controlled Diabetes Mellitus (DM) [2].
The diagnosis was previously considered an absolute contraindication to Total Knee Arthroplasty. Arthrodesis was used for neuropathic arthropathy with severe deformity and instability, showing good clinical outcomes [3]. However, a few cases reported complications like fractures and infections. Fused knees were also susceptible to trauma [3].
The outcome of total knee arthroplasty (TKA) in the Charcot joint is likely to be less favourable because of the unstable neurologic status; development of ataxia; and severe joint destruction, bone defects, and deformity[4] .
Total Knee Arthroplasty in patients with Neuropathic Arthropathy has shown a high rate of complications like periprosthetic joint infection (PJI), tibiofemoral dislocation, and periprosthetic fracture [2, 5, 6] with one study showing 47% complication rates, majority of them being aseptic loosening and poor functional outcomes [5].
However, more recent reports have described satisfactory outcomes with the use of increased constraint, stems, augments, and revision-type TKA components [2, 5, 6, 7].
There is limited literature that describes the long-term functional outcomes of patients with Neuropathy treated with constrained prosthesis. They are based on older surgical techniques and implant designs. Very few of the existing studies have a large sample size. Our study will assess the functional outcomes of doing TKA with constrained prosthesis in patients with Neuropathic Arthropathy and whether these results have changed as compared to older literature.
Our study aims to address the gap that exists in determining whether TKA with constrained prosthesis has good functional outcomes in patients with Neuropathy.
Literature review
Three studies [2, 5, 6] on Total Knee Arthroplasty (TKA) in patients with neuropathic arthropathy were reviewed. Across these studies, a total of 67 TKAs were performed in 46 patients, with follow-up periods ranging from 5 to 22 years. The number of knees treated varied from 11 to 37. All the studies reported fair to good functional outcomes. The mean range of motion (ROM) improvements differed significantly, from a decrease of 4° [6] to an increase of 19° [2], with an overall average improvement of 8.5°. Functional outcomes, measured by various scoring systems, showed an average increase of 42.5 points, ranging from a low of 37 to 82 points [2] to a high of 44.9 to 95.0 points [5].
The studies reported high complication rates, varying from 27% [2] to 47% [5] with an average complication rate of approximately 30.7%. Major complications included aseptic loosening, dislocations, infections, and fractures, often necessitating additional surgeries such as revisions, arthrodesis, or amputations. The strength of these studies lies in their focus on a challenging patient population with advanced joint pathology and their use of diverse follow-up periods to assess outcomes. Moreover, they have incorporated advanced surgical techniques and modern implants, providing insights into the potential of TKA for neuropathic arthropathy.
The limitations of these studies are small sample sizes, retrospective designs, and the absence of control groups, which limit the generalizability and robustness of their findings. Additionally, the variability in surgical approaches and the use of different prostheses add complexity to interpreting the overall effectiveness of TKA in this patient population.
Building on the findings of these studies, our hypothesis aims to address the gaps in current knowledge by evaluating the functional outcomes of TKA with constrained prostheses in a contemporary setting using more standardized surgical techniques and implant designs. Unlike previous studies, which often relied on older methods or lacked sufficient sample sizes, our study seeks to provide a more comprehensive analysis of the efficacy and safety of constrained prostheses in treating neuropathic arthropathy, thus contributing to the development of evidence-based clinical guidelines.
Hypothesis Statement
In our study, we hypothesize that TKA with constrained prosthesis in Neuropathic Arthropathy of the Knee gives good functional outcomes and is not associated with a high number of complications.

Timeline
2018-2023
Statistical analysis
Both descriptive and inferential statistics will used to evaluate the outcomes of Total Knee Arthroplasty (TKA) in patients with neuropathic arthropathy. The sample size of 25 patients is determined based on the inclusion criteria for cases from 2018 to 2023, including both retrospective and prospective data.
Primary outcomes, such as changes in range of motion (ROM) and pain scores (Visual Analog Scale, VAS), will be analyzed using paired t-tests to compare preoperative and postoperative values, with a p-value of <0.05 indicating statistical significance. The Kaplan-Meier method will be used to estimate implant survival free from aseptic and any revision at 5 and 10 years.
Secondary outcomes, including functional scores (Knee Society Score, Hospital for Special Surgery scores) and complication rates, will also be analyzed using paired t-tests, while chi-square tests will be employed for categorical data like complications. Descriptive statistics (mean, median, standard deviation) will summarise patient demographics and clinical outcomes and provide a comprehensive assessment of the efficacy and safety of TKA with constrained prosthesis in this patient population.
Discussion
Total Knee Arthroplasty (TKA) with constrained prostheses offers good functional outcomes but is associated with a higher complication rate in patients with neuropathic arthropathy. It is well-supported by scientific evidence and clinical observations. Patients with neuropathic arthropathy have severe joint destruction, instability, and deformity due to underlying neuropathy. Joint reconstruction in these patients is a significant challenge. Constrained prostheses address these issues by providing increased stability when the surrounding soft tissues are compromised. However, the altered biomechanics, poor bone quality, and reduced proprioception in these patients increase the risk of complications such as aseptic loosening, dislocations, and infections. Previous studies have reported both improved function with constrained prostheses but a higher rate of complications. Our hypothesis proposes the idea that these implants can offer significant benefits in terms of pain relief and function and are not associated with a high rate of complications.
The study might face several challenges and limitations, including a small sample size, lack of a long-term follow-up, and potential biases inherent in the retrospective study component. The small sample size limits the generalizability of the findings, and the variability in patient characteristics, such as differing degrees of joint deformity and underlying neuropathic conditions, could introduce variability in outcomes. To mitigate these limitations, strict inclusion criteria will be used to create a more homogeneous sample representative of the broader patient population. Additionally, statistical adjustments, such as stratification based on severity and underlying conditions, will be applied to reduce the impact of confounding variables. The use of standardized outcome measures and consistent follow-up protocols will further ensure reliable and comparable data.
The study's findings hold important clinical relevance, particularly for managing patients with neuropathic arthropathy undergoing TKA. The observed benefits of constrained prostheses in improving knee function and reducing pain support their use in cases where traditional implants may fail due to joint instability and severe deformity. However, the high complication rate, as seen in other studies [2, 5, 6] suggests that clinicians must carefully balance these benefits against the risks, emphasizing the importance of thorough preoperative assessment and patient selection. The results advocate for a personalized approach to care, where the decision to use constrained prostheses is based on individual risk profiles, comorbidities, and functional needs. Additionally, the findings would provide a basis for refining postoperative management strategies, including enhanced monitoring for early complications and structured rehabilitation protocols. Overall, this study could contribute valuable insights that could improve surgical decision-making, enhance patient counselling, and potentially formulate standardized treatment guidelines for patient population.
Future research should focus on having a larger sample size to improve the generalizability of the findings. Long-term follow-up studies are also needed to understand the durability of constrained prostheses and the long-term impact on patients’ quality of life. Randomized controlled trials should be conducted to compare constrained prostheses with alternative implants or conservative management strategies. Investigating patient-specific factors that predict better outcomes and identifying risk factors associated with complications could help refine patient selection criteria and surgical planning. Additionally, exploring new implant designs, surgical techniques, or adjunctive therapies that could minimize complications while maintaining functional benefits would add value to the treatment protocols. This could further enhance the understanding and management of neuropathic arthropathy, ultimately leading to improved patient outcomes.
Conclusion
The hypothesis that Total Knee Arthroplasty (TKA) with constrained prostheses provides good functional outcomes but is not associated with a high complication rate in patients with neuropathic arthropathy is a crucial area of exploration that addresses a significant gap in medical knowledge and clinical practice. This study will contribute to understanding how constrained prostheses can be effectively used in cases where joint instability and severe deformity exist. These cohort of patients usually pose challenges to the usage of traditional implants. Through this study we could evaluate the risks involved, including complication rates, which are critical for guiding clinical decision-making.
By advancing knowledge of the benefits and limitations of using constrained prostheses in this unique patient population, the study supports a more nuanced, personalized approach to TKA, emphasizing careful patient selection and tailored surgical planning. The results of this study could lay the groundwork for future research, optimize postoperative management strategies, and potentially lead to the development of standardized treatment guidelines. Ultimately, this hypothesis and its exploration could play an essential role in advancing both the science and practice of treating neuropathic arthropathy, promoting better patient outcomes and contributing to the overall improvement of orthopedic care.

Abstract
Background: Anterior shoulder dislocations are frequent, affecting 2% of people annually. Arthroscopic Bankart repair is used for soft tissue lesions or minor bone loss, while the open Latarjet procedure is preferred for significant bone loss. This study compares functional outcomes of these surgical methods.
Materials and methods: This prospective interventional study, approved by the Institutional Ethical Committee, was conducted at Maharajah Institute of Medical Sciences from January 2023 to June 2024. It included 30 patients with recurrent anterior shoulder instability, managed with either arthroscopic Bankart repair or Latarjet procedure, based on specific criteria.
Results: In an 18-month study comparing mini-open Latarjet and arthroscopic Bankart repair, 30 patients were analyzed. Age distribution was similar between groups. There were no significant differences in functional scores, recurrence rates, or overall satisfaction. The Bankart group had 13.3% recurrence, while the Latarjet group experienced 13.3% superficial infections, which resolved with treatment.
Conclusion: Both techniques were effective, but the arthroscopic Bankart repair had a higher recurrence of shoulder dislocation, while the Latarjet procedure offered better functional outcomes. In developing countries like India, the Latarjet procedure may be preferred due to its potentially better long-term results and the financial burden of repeated treatments with the Bankart repair.

Thesis Question
To Compare Functional Outcome of Arthroscopic bankart repair vs Mini open Iatarjet in management of recurrent anterior shoulder instability.
Thesis Answer
The mini-open Latarjet procedure showed better long-term outcomes and lower recurrence rates compared to arthroscopic Bankart repair for recurrent anterior shoulder instability. Despite being more invasive and costly, Latarjet may be more effective in developing countries due to its superior stability and patient satisfaction.
Introduction
Anterior shoulder dislocations are highly prevalent, with an incidence rate of 23.9 per 100,000 people, affecting about 2% of the population [1, 2]. Surgery is often necessary for recurrent dislocations due to a high risk of recurrence with nonoperative methods [3, 4].
Arthroscopic Bankart repair, utilizing suture anchors, is typically used for patients with soft tissue Bankart lesions or up to 25% glenoid bone loss. For significant Hill-Sachs defects (>25% engagement), an additional remplissage procedure is recommended [5, 6, 7]. The open Latarjet procedure is generally preferred for cases with substantial glenoid bone loss. Although there is debate over the benefits of each technique, surgical success is ultimately measured by clinical outcomes and recurrence rates [8–14].
In resource-limited settings like Nepal, cost is a significant factor. Many patients cannot afford the expensive suture anchors needed for arthroscopic repair, and insurance often does not cover these costs [15, 16].
This study aims to compare the functional outcomes of patients undergoing arthroscopic Bankart repair versus those receiving open Latarjet treatment for recurrent anterior shoulder dislocation.

Results
This study at Maharajah Institute of Medical Sciences evaluated the effectiveness of mini open Latarjet versus arthroscopic Bankart repair for recurrent anterior shoulder instability. The participants, mostly young males with a predominance of right-sided injuries and frequent prior dislocations, were equally divided between the two surgical methods.
Both techniques showed comparable functional outcomes in terms of ASES, Rowe, Quick DASH scores, and external rotation. Patient satisfaction was high for both groups, with the Latarjet group reporting slightly better satisfaction. Notably, the Bankart group experienced two cases of re-dislocation, whereas the Latarjet group had two cases of superficial wound infection. Overall, while both procedures were effective, Latarjet showed a slight advantage in patient satisfaction and fewer recurrent dislocations.
In the Bankart group, two patients had re-dislocation; one underwent an open Latarjet revision. In the Latarjet group, two patients had superficial wound infections, which resolved with treatment. No additional complications were reported in either group.

• Track Status: Majority off track.
Discussion
his study, conducted over 18 months at Maharajah Institute of Medical Sciences, compared the functional outcomes of mini open Latarjet versus arthroscopic Bankart repair for recurrent anterior shoulder instability. The Latarjet procedure is well-regarded for its triple-stabilizing effect—capsular repair, anterior glenoid augmentation, and sling effect—which can enhance stability and reduce recurrence rates compared to the Bankart repair [10 , 12 , 28].
Findings from this study support the Latarjet technique's superior performance, with lower recurrence rates and higher functional satisfaction. Specifically, the Bankart group experienced a 13.3% recurrence rate, while the Latarjet group reported no recurrences [10]. This is consistent with previous research demonstrating the Latarjet's effectiveness in improving stability and patient outcomes [11, 12]. The Bankart repair, though less invasive and cosmetically preferred, was associated with a higher recurrence rate and slightly lower patient satisfaction [ 25, 27].
Complications were noted in both procedures. Graft-related issues, including fractures and nonunion, were common, with arthroscopic methods possibly having a higher risk due to technical complexities [19]. Despite these challenges, no significant differences in complication rates were observed between the techniques in this study [30]. The open Latarjet method has been associated with concerns about wound infections and neurological injuries, but these complications were managed effectively in this cohort [16].
Both techniques resulted in minor increases in cartilage wear at the 3-month follow-up, indicating the need for longer-term monitoring [16]. This study's findings align with the broader literature, which often highlights the Latarjet procedure's superior long-term outcomes compared to Bankart repair [14]. However, the technical demands of both procedures suggest that patient-specific factors and surgeon expertise are crucial in achieving optimal outcomes.
Conclusion
• Both arthroscopic Bankart repair and the Latarjet procedure showed positive clinical outcomes for managing recurrent anterior shoulder instability. Despite the advantages of arthroscopic Bankart repair, such as being minimally invasive and having aesthetic benefits, it was associated with a higher tendency for recurrent shoulder dislocations compared to the Latarjet procedure. In contrast, the Latarjet procedure offered superior functional satisfaction and a lower recurrence rate.
• Given these findings, the Latarjet procedure may be more suitable in developing countries like India. This recommendation is based on the procedure’s potentially better long-term outcomes and its ability to minimize the financial burden associated with recurrent treatments. While arthroscopic Bankart repair is less invasive, its higher recurrence rate and the financial implications of repeated surgeries make Latarjet a more viable option in resource-constrained settings.
Clinical message
In this study comparing Mini Open Latarjet to Arthroscopic Bankart Repair for recurrent anterior shoulder instability, both techniques demonstrated positive clinical outcomes. However, the Arthroscopic Bankart Repair was associated with a higher rate of recurrence, while the Latarjet procedure provided superior functional satisfaction and lower recurrence rates. These findings suggest that, despite its invasiveness, the Mini Open Latarjet may offer better long-term stability and patient outcomes, particularly in resource-constrained settings where repeated treatments could be financially burdensome. Future studies with longer follow-ups are needed to confirm these results and guide optimal treatment choices.
