patella fracture

PURPOSE: Infrapatellar pole fractures are challenging injuries that require appropriate treatment to ensure optimal functional outcomes. This study aimed to introduce the application of the Suture Bridge technique using the 5-Ethibond for the treatment of infrapatellar patella fracture. METHODS: Five cases of infrapatellar pole fracture that were treated at our institution between February 2020 and September 2021. The patients included one male and four females, with an average age of 66 years (range: 60-77 years)...

BACKGROUND: There are several imaging-based measurements for patellofemoral height, which are obtained from sagittal images. However, these methods can be misleading with sagittal oblique slices and when the patella is tilted and/or chronically subluxated. This study aimed to describe a simple method of measuring patellar height using axial patellotrochlear overlap (APTO) on MRI. METHODS: A retrospective observational study of 97 knees from 251 patients, excluding those with fractures, massive effusion, or patellofemoral conditions...

The management and underlying causes of patellar periprosthetic fractures (PPF) after total knee arthroplasty (TKA) constitute an issue of growing importance given the rising frequency of these procedures. Patella periprosthetic fractures, though relatively rare, pose significant challenges and are a frequent indication for revision surgeries. Despite a decrease in overall incidence, PPFs remain the second most common type of periprosthetic fractures after TKA. Several factors have been identified and associated with patient-specific factors, surgical technique errors, and implant-related causes...

Fixation of osteochondral fractures after patellar dislocation is typically done using an open approach due to the location of the defect. This is traditionally performed through a medial parapatellar arthrotomy to allow adequate visualization. By using the joystick method, adequate visualization is achieved with a smaller arthrotomy. Careful placement of the joystick in the planned anchor site of the medial patellofemoral ligament reconstruction reduces the number of drill sites in the patella.

INTRODUCTION: Distal pole of patella avulsion fracture with tibial tuberosity avulsion has been frequently reported as a bifocal patellar tendon injury. However, an osteochondral lateral patella facet fracture with a longitudinal split in the patella tendon in addition to these avulsion fractures has never been documented previously. Hence, we now report this trifocal patellar tendon injury. CASE REPORT: An adolescent with a trifocal patella tendon injury underwent a fixation with a combination of transosseous pull- through sutures, suture tape, and knotless anchor...

INTRODUCTION: Patella fracture can occur due to direct injury to the knee or indirect eccentric contraction of the quadriceps tendon. These injuries can present in different configurations which require acceptable reduction and good fixation. Patients are at risk of not only losing their knee extensor mechanism but also having a defective patellofemoral articulation. Hence, the main aim in treating such fractures is to restore the knee extensor mechanism. Surgical options for treating patella fracture include tension band wiring, wiring through cannulated screws, fixation with plate, and suture anchor (SA) fixation...

Ipsilateral hip and knee dislocation is a rare and complex injury that usually results from high-energy trauma. Only 14 cases were reported in the literature so far. We report the case of a 35-year-old man who presented with an ipsilateral right hip and knee dislocation after being involved in a road traffic accident. A contralateral floating knee was associated. The hip dislocation was associated to a posterior wall fracture of the acetabulum and a femoral head fracture. The knee dislocation was compound and associated with a patella fracture...

BACKGROUND: Hyponatremia and hypokalemia are common electrolyte imbalances in trauma patients and have been identified to be risk factors for a fall. In addition, hyponatremia was reported to be related to osteoporosis and fragility fractures, while the association between hypokalemia and osteoporosis has only been reported in rare case reports. This study investigated the impact of hyponatremia and hypokalemia on the incidence of fractures in various body regions of adult trauma patients, using the propensity score-matched patient cohort to reduce the influence of patients' baseline characteristics...

PURPOSE: This retrospective observational cohort analysis aims to address diagnostic and therapeutic challenges in managing osteochondral fractures (OCFs) resulting from acute patella dislocation and ankle sprains in children. METHODS: The study includes 15 children treated for OCFs between January 2020 and July 2022. Data were obtained from medical records and analyzed using logistic regression. RESULTS: The diagnostic and treatment algorithm involves detailed history, clinical examination, and imaging, with MRI guiding therapeutic decisions...

Impetigo is a pediatric skin infection characterized by the presence of pathognomonic "honey-crusted" lesions caused by either  Staphylococcus aureus  or  Streptococcus pyogenes . The diagnosis of impetigo is largely based on clinical judgment, confirmatory skin cultures, and Gram staining. Surgical site infections following patellar surgery are a relatively uncommon occurrence, with the most common causative organisms being  Staphylococcus aureus ,  Streptococcus pyogenes, Pseudomonas aeruginosa,  and other gram-negative bacilli...

OBJECTIVES: To assess if a suprapatellar (SP) approach, when compared to an infrapatellar (IP) approach, yielded less patient reported anterior knee pain and higher patellofemoral joint function at 6 weeks and 12 months post operatively, when treating tibial fractures with intramedullary nailing. DESIGN: Prospective, parallel group randomized control trial. SETTING: Tertiary level one trauma care centre, Brisbane, Australia. PATIENTS SELECTION CRITERIA: Skeletally mature patients with an acute diaphyseal tibial fracture (AO/OTA 41A2/3, 42 A1- 43A3) amenable to an IMN were included...

Background Thyroid cancer is one of the five most common cancers causing bone metastasis. If there is an increase in serum thyroglobulin-antithyroglobulin levels in differentiated thyroid cancer or calcitonin levels in medullary thyroid cancer, patients should be evaluated for recurrence and distant metastasis. The skeleton is the second most common site of distant metastasis in thyroid cancer after the lung. Bone metastases cause pain, fractures, and spinal cord compression, severely reducing the quality of life...

BACKGROUND: Quadriceps tendon extensor mechanism disruption is an infrequent but devastating complication after total knee arthroplasty (TKA). Our knowledge of specific risk factors for this complication is limited by the current literature. Thus, this study aimed to identify potential risk factors for quadriceps tendon extensor mechanism disruption following TKA. METHODS: A retrospective cohort analysis was performed using the PearlDiver Administrative Claims Database...

BACKGROUND: Although the risk factors for patellofemoral dislocation are clearly defined, risk factors for osteochondral fracture (OCF) after patellar dislocation are not as well defined. The aim of this study was to investigate the risk factors for OCF by evaluating patients with and without OCF after first-time acute patellar dislocation. METHODS: This multicenter study was conducted as a retrospective examination of the radiologic measurements on the magnetic resonance imaging of 306 patients...

PURPOSE: The topic of elective implant removal (IR) in healed fractures of the lower extremity remains controversial, particularly when unspecific symptoms of discomfort, which cannot be quantified, are the primary indication. This study aims to assess indications and outcomes of elective IR of the lower extremity, focusing on unspecific symptoms of discomfort and patient satisfaction postoperatively. MATERIALS AND METHODS: The retrospective cohort study was conducted at a single level I academic trauma center...

Osteochondral fractures of the patella, also known as "flake fractures," frequently occur after patellar dislocation. In such fractures, a piece of patellar cartilage with subchondral bone breaks off due to patellar dislocation or subsequent reposition. Various surgical techniques have evolved for surgical therapy with the goal of realigning the patellar cartilage. This article presents a cost-effective surgical technique for achieving stable refixation of large osteochondral fragments in patellar flake fractures...

RATIONALE: Extremity injuries resulting from motor vehicle collisions, especially those leading to bone-exposed wounds, present challenges for achieving effective wound coverage. Such injuries are susceptible to complications including infections, osteomyelitis, and unexpected amputations due to inadequate blood supply. Severe traumatic degloving injuries often entail damage to the surrounding blood vessels, making local or free flaps impractical choices in many cases. Consequently, treatment options may vary based on distinct clinical scenarios, with no standardized guidelines available...

Inferior pole fractures of the patella are a type of patellar fracture that has various complexities. Most current techniques are associated with hardware-related complications, which is one of the main concerns when treating this complex fracture. We present a new technique that does not require metal implant removal, causes little to no irritation of the quadriceps muscle, and provides strong fixation that allows for early range of motion postoperatively.

The patella is the largest sesamoid bone in the body and an important structure of the extensor apparatus which is under undue stress during flexion and extension of the knee. Bilateral fracture of the patella without trauma is a very rare event and may be multifactorial without a single cause. A repetitive stress reaction in a previously predisposed bone can be an important cause. We report a case of a 45-year-old female with a nontraumatic bilateral transverse patella fracture with loss of extensor mechanism...

A patellar fracture is a fracture of the kneecap. The patella is a shield that plays a vital function in the biomechanics of the knee joint. Traumatic knee injuries produced by direct trauma or quick quadriceps contraction with the knee bent can result in the loss of the extensor mechanism. A 69-year-old female patient presented with pain in her right knee following a slip at her home, which resulted in an injury to her knee. Subsequently, a radiological investigation suggests a patellar fracture. The purpose of this case report is to investigate the rehabilitation techniques and concrete the result...
