Unusual Multiple Recurrences of Soft Tissue Giant Cell Tumors in a Patient Above 60 Years.

Primary giant cell tumors of soft tissues (GCT-ST) are rare neoplasms that share histopathological and immunohistochemical characteristics with osseous giant cell tumors. While GCT-ST generally exhibits a benign progression and can affect individuals of various ages, older patients may face a higher risk of recurrence and aggressive disease progression. In this case report, we present the case of a 63-year-old woman who experienced recurrent GCT-ST nine months after the complete excision of an initially localized tumor.

Measurement of Condylar Offset and Posterior Condylar Cartilage Thickness in Normal Knees: An MRI Study From Saudi Arabia.

Background The maximum amount of knee flexion after total knee replacement is largely determined by the knee's posterior condylar offset (PCO). Using magnetic resonance imaging (MRI), this study examined the relationship between PCO and the thickness of the femoral posterior condylar cartilage (PCC) in healthy people. Methodology We reviewed the medical records of 300 skeletally mature patients who did not exhibit symptoms of knee arthritis and had undergone MRI for traumatic soft tissue knee injuries that did not affect the femoral PCC.

Objectives: The demand for orthopedic surgery is expected to increase as the Saudi population grows and ages. Therefore, this study aimed to assess the interest of medical students and interns in orthopedic surgery and the factors that influence their interest.

Methods: This cross-sectional study was conducted using a structured questionnaire adapted from a similar study and modified by the authors.

Outcome of Surgical Management of Dermatofibrosarcoma Protuberance: A Single-Institution Multidisciplinary Approach.

Introduction: Dermatofibrosarcoma protuberans (DFSP) is a rare, slow-growing, and locally aggressive soft tissue tumor with a high recurrence rate and metastatic potential, even with the proper treatment.

Methods: This was a retrospective (case series) study that took place at King Abdulaziz Medical City, Riyadh, Kingdom of Saudi Arabia, to determine the outcomes of and appropriate margin excision for DFSP. All patients who were diagnosed with DFSP from 2016 to 2021 were included.

Patient-related risk factors of prosthetic joint infections following total hip and knee arthroplasty at King Abdulaziz Medical City, a 10-year retrospective study.

Background: Total joint arthroplasty (TJA) can be associated with the development of periprosthetic joint infection (PJI). It is necessary to determine the modifiable and non-modifiable risk factors of PJI to provide optimum healthcare to TJA candidates.

Methods: This single-center retrospective review investigated 1198 patients who underwent TJA from 2012 to 2022.

Etiologies of Orthopedic Implant Removal Among Patients Who Underwent Orthopedic Fixation Surgeries in King Abdulaziz Medical City.

Background: Hardware removal surgeries are considerably common. However, the justifications for these surgeries are debatable. The indications may vary from pain, surgical site infection, or failure of osteosynthesis.

Lateral epicondyle to the joint line distance is a precise landmark for determination of an accurate knee joint line: an observational retrospective study.

Purpose: To assess a quantitative and reproducible association between the position of the knee joint line and recognizable anatomical landmarks around it in order to help in restoring joint line in arthroplasty cases.

Methods: Magnetic resonance imaging (MRI) of 130 normal knees were investigated. Anatomical measurements of the knee joint distances on the obtained planes were performed manually by distance measurements using a ruler tool, followed by 6 anatomical bony landmarks determination about the knee to identify the joint line which included the joint line, medial epicondyle, lateral epicondyle, medial flare, lateral flare, and proximal tibiofibular joint.

Single bone forearm reconstruction of proximal ulna metastatic lesion: A case report.

Introduction And Importance: Colorectal cancer rarely metastasizes to the bones, and if so, metastasis usually occurs in the axial skeleton. We encountered a rare case of a metastatic lesion to the right ulna arising from colonic adenocarcinoma that was treated by resection of the proximal ulna and radial neck-to-humerus trochlea transposition to salvage the limb.

Case Presentation: A 60-year-old man previously diagnosed with colonic adenocarcinoma presented with a single bony metastatic lesion in the right proximal ulna and was referred to our clinic for assessment.

The effect of gender, age, and body mass index on the medial and lateral posterior tibial slopes: a magnetic resonance imaging study.

Background: The posterior tibial slope (PTS) is crucial in knee joint stability and in maintaining the natural movement of the knee. An increase in the PTS is associated with various knee pathologic conditions, such as anterior cruciate ligament (ACL) injury and anterior tibial translation (ATT). In the present study, we aimed to establish native medial and lateral PTS values for adult Saudis and to identify any association between PTS and gender, age, and body mass index (BMI).
