Furthermore, the authors performed a pilot study on tibial bone resections after having performed the tibial saw cuts of unicompartmental knee prostheses in 0° and 3° in the coronal plane. The study’s objective was achieved by devising...
Traumatic hemipelvectomy (TH) is a rare and extremely severe injury of the pelvic area, which is often life-threatening and associated with a high mortality rate. Individual treatment is focused on the pelvic fracture and the type of accompanying injuries. The management of these severely injured patients places a considerable challenge on the resuscitation team. Patient...
Total femur replacement (TFR) is a solution that allows orthopedic surgeons to address the most complicated cases in hip, femur, and knee reconstruction. Complete femur prostheses are used in both oncologic patients with femur tumors that require resection and in cases of complicated prosthetic failure with massive bone defects. TFR is an alternative to hip disarticulation that...
Synovial leukocyte cell count (LC) and polymorphonuclear percentage (PMN%) are key parameters in the diagnostic workup of periprosthetic joint infection (PJI). Despite ongoing debates regarding optimal thresholds—particularly for reliably excluding low-grade infections—no study has investigated potential confounders such as intra-individual, time-dependent variability of LC and...
The Coronal Plane Alignment of the Knee (CPAK) classification categorizes knee phenotypes based on constitutional limb alignment and joint line obliquity (JLO). Restricted Inverse Kinematic Alignment (RIKA) is a surgical philosophy that incorporates calculated perioperative parameters to achieve patient-specific alignment. This study investigated the reproducibility of restoring...
The amount of change in coronal alignment by unicompartmental knee arthroplasty (UKA) is important when considering its long-term results. This study investigated whether the amount of change in mechanical hip-knee-ankle (mHKA) angle by medial fixed-bearing UKA can be predicted based on the arithmetic hip-knee-ankle (aHKA) angle, an indicator of bony nature that is independent of...
Femoroacetabular impingement (FAI) is a common cause of hip pain and dysfunction, particularly among athletes, including football players. The condition is characterized by abnormal contact between the femoral head-neck junction and the acetabulum, leading to cartilage damage and labral tears. Hip arthroscopy has emerged as a minimally invasive treatment option, offering faster...
The rising prevalence of obesity has increased the demand for total knee arthroplasty (TKA), but the impact on outcomes, particularly in Class I and II obesity, remains inconclusive. This study aimed to compare early in-hospital post-TKA outcomes in older patients with Class I (BMI 30–34.9 kg/m²) and Class II obesity (BMI 35–39.9 kg/m²). Using data from the Nationwide Inpatient...
Femoroacetabular impingement (FAI) syndrome is a condition characterised by irregularities in the femur or acetabular rim, leading to hip pain, increased risk of osteoarthritis (OA), and potential need for total hip arthroplasty (THA). Non-surgical treatments are the first-line approach. However, arthroscopic surgery has become more prevalent due to its promising short- and...
Although surgical alignment of the rear-foot might be sufficient to achieve acceptable correction of pronation-distortion deformity, concomitant correction of the medial arch might improve functional results. We present our experience with combined hind-foot alignment and medial arch reconstruction by in-situ naviculocuneiform arthrodesis for treatment of flexible flatfoot in...
Total Knee Arthroplasty (TKA) is the primary definitive treatment for knee osteoarthritis (OA) and has been essential in helping patients reduce knee pain and regain mobility. There is a need to assess whether various factors such as surgical complications from primary TKA, pre and postoperative range of motion (ROM), Charlson Comorbidity Index (CCI), comorbidities other than CCI...
The dynamic lumbopelvic interaction has gained increasing importance in hip-preserving surgery, even though the coexistence of lumbopelvic malalignment with pre-arthritic hip deformities has been poorly studied. This study aimed to examine (I) the frequency of static and functional lumbopelvic malalignment (II) and to compare the lumbopelvic alignment between symptomatic mild to...
This study aims to investigate whether early surgery in patients under active DOAC (direct oral anticoagulation) therapy with trochanteric, proximal femur fractures leads to higher postoperative blood loss. A prospective cohort study on DOAC patients with trochanteric, proximal femur fractures undergoing early surgery (≤ 24 h) was conducted. Propensity score matching with a...
Osteoarthritis of the knee (KOA) is a leading cause of disability in the aging population. The treatment of choice in most stages is a conservative multimodal approach. Previous studies were able to prove the efficiency of physical therapy for improvement. Therefore physical therapy, besides pain medication, is one of the most common used forms of therapy for KOA. This study aims...
Orthopedic drilling and screw placement require precision to obtain the effect of bicortical screwing and avoid complications such as soft tissue damage. Traditional manual depth gauges, while effective, are prone to human error. This study evaluates the usability and acceptability of an automated electronic depth gauge compared to a conventional manual depth gauge in a...
Total knee arthroplasty is a well-established procedure that aims to improve pain, mobility and function. Multiple studies have demonstrated a strong correlation between patient satisfaction and their preoperative expectations, including return to sport. This study aims to assess the level of post-operative activity and rate of return to sport after TKA in an Australian...
Performing total joint replacements (TJR) in patients with solid organ transplantations (SOT) is associated with an increased risk of complications and reoperation. The aim of this study is to report on implant survivorship, patient survivorship, and complication rates for total knee arthroplasty (TKA) and total hip arthroplasty (THA) performed in heart, lung, liver and kidney...
