Patients posture affects clinical outcomes and range of motion after reverse total shoulder arthroplasty: A clinical study.

Background: Movement limitations following implantation of reverse total shoulder arthroplasty (rTSA) have been observed in some patients postoperatively, with implant design and positioning recognized as important influential factors. Recent analyses have identified patient's posture, measured as scapula internal rotation on computed tomography (CT), as an additional factor influencing the functional outcome after rTSA. However, no clinical study has correlated the preoperatively photo-documented posture to functional outcome.

The Sagittal Tibial Tubercle Trochlear-Groove Distance Is Not Equivalent on Magnetic Resonance Imaging and Computed Tomography Measurements in Patients With Patellar Instability.

Purpose: To analyze the difference of the sagittal tibial tubercle trochlear-groove (sTTTG) on magnetic resonance imaging (MRI) and computed tomography (CT) and to assess the influence of the knee flexion angle (KFA) and tibiofemoral (TF) rotation on the sTTTG.

Methods: All patients who underwent patellar-stabilizing surgery for patellar instability between January 2019 and July 2023 at a single institution were included in the current study. Patients were included when a preoperative MRI of the assessed knee and standardized CT imaging in full knee extension of the lower extremity was available.

Combined Correction of Coronal and Rotational Deformities of the Femur With Distal Femoral Osteotomy Using Patient-Specific Instrumentation.

Background: Distal femoral osteotomy (DFO) can be used to simultaneously correct coronal and rotational deformities. Patient-specific instruments (PSIs) are known to be helpful in such complex osteotomies, but data on surgical accuracy for the combined correction of coronal and rotational deformities of the femur are missing.

Purpose: To investigate the radiological results of DFO for simultaneous correction of coronal and rotational deformities using PSIs.

Evaluating the Corrected Femoroepiphyseal Acetabular Roof Index in Patients With Borderline Dysplasia Undergoing Periacetabular Osteotomy or Hip Arthroscopy.

Background: Identifying hip instability in symptomatic patients with borderline dysplasia of the hip (BDH) is of paramount importance, as it can influence both surgical decision-making and surgical outcomes. The femoroepiphyseal acetabular roof (FEAR) index is strongly affected by the hip adduction/abduction angle during the pelvic radiograph, which has not yet been considered in the recommended threshold values.

Purpose: To compare the corrected FEAR index in symptomatic patients with BDH treated with pelvic periacetabular osteotomy (PAO) or hip arthroscopy.

Small changes of femoral torsion in varus or valgus distal femoral osteotomy using patient-specific instruments.

Purpose: Hinge fractures show a relatively high incidence in varus and valgus distal femoral osteotomy (DFO) and can lead to delayed- or non-union. Another observed complication of a hinge fracture is an unintentional change of the postoperative femoral torsion of up to + 9.5° in conventionally performed DFO.

Simultaneous patellar tendon and anterior cruciate ligament rupture: a systematic review, meta-analysis and algorithmic approach.

Introduction: Isolated patellar tendon (PT) or anterior cruciate ligament (ACL) ruptures are common injuries, yet the co-occurrence of both presents a rare challenge for clinicians. The objectives of the study are to document diagnostic and therapeutic approaches, outcomes, and complications of combined PT and ACL injuries and to develop an algorithm to guide clinicians in decision-making.

Methods: The systematic review und metanalysis was conducted according to the PRISMA guidelines.

No significant change of tibiofemoral rotation after femoral rotational osteotomy in patients with patellofemoral instability.

Purpose: An increased value of tibiofemoral rotation is frequently observed in patients with patellofemoral instability or maltracking. Nevertheless, the appropriate approach for addressing this parameter remains unclear so far. One potential approach for correcting tibiofemoral rotation is femoral rotational osteotomy.

Femoro-Epiphyseal Acetabular Roof Index Values on Anteroposterior Pelvic Radiographs Significantly Increase With Hip Adduction and Decrease With Abduction.

Purpose: To investigate the impact of hip adduction and abduction on the femoro-epiphyseal acetabular roof (FEAR) index using conventional anteroposterior pelvic radiographs of patients with borderline hip dysplasia (BHD).

Methods: Patients with BHD (lateral center edge angle [LCEA] with values of 18° ≤ LCEA <25°) and who were subject to periacetabular osteotoym were selected from a consecutive retrospective cohort from January 2009 to January 2016. The hip ad-/abduction (adduction handled as negative values) and the FEAR index (lateral opening angles handled as positive values) were measured in the initially standardized acquired pelvic radiographs.

Acute surgical treatment of entrapped avulsion fractures of the inferior angle of the scapula in adults: Two case reports.

Inferior angle of scapula fractures are rare, and can lead to pain and impaired shoulder function. This report details the cases of two adult patients with inferior angle of scapula fractures who underwent acute surgical reduction and suture repair. In both patients, the avulsed fragment was dislocated and entrapped in the scapulothoracic joint resulting in noticeable crepitations and disturbed scapulothoracic rhythm during active range of motion.

Patellofemoral arthroplasty with onlay prosthesis leads to higher rates of osteoarthritis progression than inlay design implants: a systematic review.

Purpose: The aim of this study was to report the clinical and functional outcomes, complication rates, implant survivorship and the progression of tibiofemoral osteoarthritis (OA), after new inlay or onlay patellofemoral arthroplasty (PFA), for isolated patellofemoral OA. Comparison of different implant types and models, where it was possible, also represented one of the objectives.

Methods: A systematic literature search following PRISMA guidelines was conducted on PubMed, Scopus, Embase and Cochrane databases, to identify possible relevant studies, published from the inception of these databases until 11.
