Charcot knee is a rare condition with few reported cases in the literature. Although the clinical presentation is highly variable, Charcot knee classically presents with painful arthropathy in addition to instability and decreased range of motion. Herein, we describe the case of a 72-year-old man with idiopathic Charcot knee. The diagnosis was established on the basis of history of neuropathic arthropathy of the knee, supported by knee radiographs and the exclusion of all known etiologies of Charcot knee. Because of a highly destructed knee joint, the patient underwent a total knee arthroplasty using the Global Modular Replacement System proximal tibial prosthesis. The surgery was done without any major complications, resulting in symptomatic and functional improvements.

Background: Limb amputation is a life-altering event with substantial physical, psychological, and social consequences. Despite advances in healthcare, amputation remains a major global health concern, particularly in regions with high burdens of diabetes and vascular disease. This study aims to analyze demographic characteristics, etiologies, and trends in amputations over a ten-year period at a tertiary-care center. Methods: We retrospectively reviewed medical records of patients who underwent amputation at our tertiary-care hospital. Collected variables included patients’ demographics, etiology, level of amputation, type of admission, and surgical specialty involved. Descriptive statistics were used to summarize the data. Associations between categorical variables were analyzed using chi-square tests, with post hoc pairwise comparisons adjusted using the Bonferroni method where applicable. Continuous variables were compared using the Mann–Whitney U test. A p-value of <0.05 was considered statistically significant. All analyses were conducted using IBM SPSS version 26.0. Results: A total of 647 patients underwent amputation, with a mean age of 56 years and a male predominance (65%). Diabetic complications were the leading cause (67.7%), followed by trauma (11.7%) and vascular diseases (11.6%). Lower limb amputations were more prevalent, with toe amputations being the most frequent (39%). Emergency procedures accounted for 72% of cases, and vascular surgery was the most involved specialty, followed by orthopedic surgery. Conclusions: Our study highlights a substantial burden of amputations, predominantly involving the lower limb, as well as a significant association with diabetic complications. These findings emphasize the urgent need for integrated diabetic care, early interventions, and public health strategies to reduce the burden of amputations in Saudi Arabia.

Background and Objectives: Diabetic foot disease is a major cause of lower-limb amputation and is associated with substantial morbidity and mortality. While amputation is often considered definitive treatment, postoperative outcomes and their predictors remain incompletely characterized. Materials and Methods: This retrospective cohort study included all patients who underwent diabetic foot amputation at a tertiary care center between January 2015 and August 2025. Demographic data, comorbidities, laboratory parameters, and amputation-related variables were collected. The primary outcome was postoperative complications. Secondary outcomes included readmission, re-amputation, ICU admission, length of stay, and mortality. Logistic regression was used to identify predictors of postoperative complications. Results: A total of 437 patients were included (mean age 62.0 ± 11.8 years; 65.7% male). Postoperative complications occurred in 52.1% of patients, most commonly infections (31.6%) and acute kidney injury (18.1%). Readmission occurred in 50.6%, re-amputation in 23.4%, ICU admission in 28.7%, and mortality in 17.8%. On multivariable analysis, preoperative serum albumin was the only independent predictor of postoperative complications (aOR 0.944, 95% CI: 0.913–0.976; p < 0.001). Conclusions: Postoperative complications following diabetic foot amputation are common and associated with significant healthcare utilization and mortality. Preoperative hypoalbuminemia was the only independent predictor of postoperative complications, supporting its utility as an integrated biomarker of systemic illness (including inflammatory burden/infection and hepatic synthetic function) for perioperative risk stratification.

Arthroscopic reconstruction of the anterior cruciate ligament has been modernized through new materials and novel surgical techniques. The usage of bioabsorbable screws for tibial fixation may potentially lead to complications, such as formation of a tibial tunnel or pretibial cysts. This is a relatively rare complication, but it has been described in the literature. The pathomechanism of cyst formation, however, still remains poorly understood. In this case report, we present a case of a healthy 23-year-old gentleman who had left tibia vara, which was treated surgically with proximal tibia corrective osteotomy with plate and screw fixation and subsequent hardware removal. Later in his life, he injured his anterior cruciate ligament, which required arthroscopic reconstruction. Years after, he developed a pretibial synovial cyst, which was visualized on magnetic resonance imaging. We reviewed previously published cases with similar presentations to help describe the possible etiology of intraosseous (tibial tunnel) cysts.

Fractures of the humeral shaft are commonly associated with radial nerve injury because of the anatomical course of the nerve. An ulnar nerve injury is rarely associated with such fractures. We present a case of a humeral shaft fracture with combined radial and ulnar nerve injuries in a female adult patient. The patient subsequently underwent radial and ulnar nerve exploration with internal fixation of the left humerus. According to our literature review, no similar cases were previously reported.
