Simultaneous Bilateral Femoral Osteonecrosis in Gaucher Disease.

Gaucher disease (GD) is one of the most common lysosomal storage disorders. Bone complications are the most critical irreversible consequence of GD. Osteonecrosis (ON) of the femoral head inevitably leads to osteoarthritis and may be managed by hip arthroplasty.

Excessive Sagittal Slope of the Tibia Component during Kinematic Alignment-Safety and Functionality at a Minimum 2-Year Follow-Up.

The aim of this study was to assess the safety and functional outcomes of excessive sagittal alignment in the unrestricted kinematic alignment technique for total knee arthroplasty (TKA). A retrospective, single-center study was conducted between 2018 and 2020, including patients undergoing primary TKA with a minimum 2-year follow-up. EOS imaging conducted before and after surgery was reviewed for overall alignment, and a number of measurements were taken, including sagittal tibial slope and other tibia and femur component positioning.

Minimum 2-Year Radiographic and Clinical Outcomes of Unrestricted Kinematic Alignment Total Knee Arthroplasty in Patients with Excessive Varus of the Tibia Component.

Kinematic alignment (KA) total knee arthroplasty (TKA) has gained much attention in recent years. However, debate remains on whether restrictions should be made on the tibia cut. The purpose of this study was to assess the safety and functional outcomes of excessive varus cuts.

Minimum 2-Year Radiographic and Clinical Outcomes of Kinematic Alignment Total Knee Arthroplasty in the Valgus Knee.

Kinematic alignment (KA) total knee arthroplasty (TKA) has gained popularity in the past decade, but outcomes of KA-TKA in the valgus knee have never been specifically evaluated. In this retrospective single institution study, we analyzed patient reported outcomes and radiographic measurements at minimum 2 years following KA-TKA for valgus knees ( = 51) and compared the results to KA-TKA performed for non-valgus knees ( = 275). The same approach, technique, and implants were used in both groups without the need to release soft tissues or use constrained implants.

Reliability and validity of the Hebrew version of the forgotten joint score for assessing the outcomes of total knee arthroplasty.

Background: This prospective study aimed to assess the reliability and validity of the Hebrew version of the forgotten joint score-12 in patients undergoing total knee arthroplasty, because it is going to be used in the Hebrew-speaking populations in Israel.

Methods: The English version of forgotten joint score-12 was translated into Hebrew version by using the standard procedures and in collaboration with its authors. The consecutive patients who had undergone total knee arthroplasty in a single hospital were asked to fill out the Hebrew version of forgotten joint score-12, Oxford knee score, Short Form 12, and visual analog scale.

Patients undergoing staged bilateral knee arthroplasty are less aware of their kinematic aligned knee compared to their mechanical knee.

Objective: To compare knee joint awareness following kinematic alignment (KA) TKA in patients who had previously undergone mechanical alignment (MA) on their contralateral knee.

Methods: We performed a retrospective study of all consecutive patients who underwent staged bilateral TKA, the first using MA technique and the second utilizing the KA technique, without patient specific instrumentations. Primary outcome was assessed by the Forgotten Joint Score (FJS) with a minimum 1-year follow-up.

The Missing Piece: A Subtrochanteric Hip Fracture Presenting with Abdominal Pain: A Case Report.

Case: A 33-year-old man presented with acute abdominal and left hip pain after being struck by a motor vehicle. Radiographs revealed a comminuted left subtrochanteric femoral fracture. Computed tomography demonstrated a large pelvic hematoma and a radiopaque mass in the abdomen.

The Sphygmomanometer Pain Test: A Simple Method for Identifying Patients at Risk of Excessive Pain after Total knee Arthroplasty.

Background: Despite the overall success of total knee arthroplasty (TKA), a relatively large proportion of patients remain dissatisfied with the outcome. We hypothesized that patients with a lower threshold for pain were more likely to have worse outcomes after TKA.

Methods: Forty-eight consecutive patients with primary knee osteoarthritis graded a standardized painful stimulus caused by inflating a sphygmomanometer placed on the forearm, on a visual analog scale (VAS) scale before their TKA.

Severe vascular complications and intervention following elective total hip and knee replacement: A 16-year retrospective analysis.

Introduction: Iatrogenic vascular injuries associated with elective orthopaedic joint procedures are relatively rare, however when they do occur they carry a risk of significant morbidity and mortality. The aim of this study was to investigate the incidence of vascular complications and resultant need for specialist intervention following elective total hip replacement (THR) and total knee replacement(TKR).

Methods: This was a retrospective analysis of prospectively collected data.

New approach for the rehabilitation of patients following total knee arthroplasty.

Purpose: To investigate the effect of a biomechanical therapy on gait, function and clinical condition in patients following total knee arthroplasty (TKA).

Methods: Seventeen TKA patients participated in the study. Patients received a biomechanical therapy AposTherapy).

A non-invasive biomechanical device and treatment for patients following total hip arthroplasty: results of a 6-month pilot investigation.

Background: The purpose of the study was to examine the effect of a foot-worn biomechanical device on the clinical measurements and gait patterns of patients with total hip arthroplasty (THA).

Methods: Nineteen patients, up to 3 months post-THA, were enrolled to the study. Patients underwent a computerized gait analysis to calculate spatiotemporal parameters and completed the Western Ontario and McMaster Universities osteoarthritis index and the SF-36 health survey.

Long-Term Effects of AposTherapy in Patients with Osteoarthritis of the Knee: A Two-Year Followup.

Several biomechanics treatments for knee osteoarthritis (OA) have emerged with the goal of reducing pain and improving function. Through this, researchers have hoped to achieve a transition from the pathological gait patterns to coordinated motor responses. The purpose of the study was to determine the long-term effects of a therapy using a biomechanical device in patients with knee OA.

The outcome of a novel biomechanical therapy for patients suffering from anterior knee pain.

Background: This study was devised to examine the effect of a novel biomechanical therapy for patients suffering from anterior knee pain (AKP).

Methods: A retrospective analysis of 48 patients suffering from AKP was performed. Patients underwent a gait evaluation, using an electronic walkway mat, and completed the SF-36 health survey and the WOMAC questionnaire at baseline and after 3 and 6months of therapy.

Differences in gait pattern parameters between medial and anterior knee pain in patients with osteoarthritis of the knee.

Background: Patients with osteoarthritis of the knee have unique spatiotemporal gait alterations. These gait changes have not yet been differentiated according to the location of knee pain. The purpose of this study was to compare the gait patterns of patients with symptomatic knee osteoarthritis that exhibit either anterior or medial joint pain.

The Chondrogenic Potential of Mesenchymal Cells and Chondrocytes from Osteoarthritic Subjects: A Comparative Analysis.

Objective: The multipotential nature of stem or progenitor cells apparently makes them the ideal choice for any cell therapy, but this as yet remains to be proven. This study (30 subjects) was designed to compare the potential to repair articular cartilage of chondrocytes taken from different regions in osteoarthritic cartilage with that of mesenchymal stem cells prepared from bone marrow of the same subject.

Design: Cartilage biopsies, bone marrow, and blood samples were taken from each of 30 individuals with chronic osteoarthritis (aged 62-85 years) undergoing total knee replacement.

The effect of hyaluronan injections into human knees on the number of bone and cartilage wear particles captured by bio-ferrography.

Osteoarthritis is characterized by degradation of cartilage and subchondral bone, releasing wear particles into the synovial fluid. Intra-articular injections of exogenous hyaluronan are often given to patients suffering from osteoarthritis in order to compensate for the reduction in the level of endogenous hyaluronan and to restore the rheological properties of the synovial fluid. The exact effect of these injections is still ambiguous.

A treatment applying a biomechanical device to the feet of patients with knee osteoarthritis results in reduced pain and improved function: a prospective controlled study.

Background: This study examined the effect of treatment with a novel biomechanical device on the level of pain and function in patients with knee OA.

Methods: Patients with bilateral knee OA were enrolled to active and control groups. Patients were evaluated at baseline, at 4 weeks and at the 8-week endpoint.

The correlation between pes planus and anterior knee or intermittent low back pain.

Background: Anterior knee pain and intermittent low back pain are among the most common orthopedic complaints of adolescents. However, little is known about pes planus and its relative risk for these symptoms. The goal of the study was to track the prevalence of pes planus in adolescents, and examine its associated risk to anterior knee pain and intermittent low back pain, respectively.

The use of dynamic CT surview for cervical spine clearance in comatose trauma patients: a pilot prospective study.

Background: Bedside flexion and extension fluoroscopy was proposed for detecting occult ligamentous instability in comatose trauma patients. Nevertheless, a recent study showed that the C7-T1 motion segment is rarely visualised by this technique. We propose a new method for clearing the cervical spine in comatose patients.
