Patellofemoral dysbalance and genua valga: outcome after femoral varisation osteotomies.
Patellofemoral dysbalance may be caused by trochlear dysplasia, an elevated TTTG distance, femoral or tibial torsional deformities, patella alta, or a genu valgum. The surgical procedure for the treatment of a genu valgum is varisation osteotomy, usually in the femoral aspect. Several authors believe that a genu valgum is one cause of patellofemoral dysbalance, but studies about the outcome of the treatment with a varisation osteotomy are rare. ⋯ IV, case series.

Comparative StudyEffects of tibial baseplate shape on rotational alignment in total knee arthroplasty: three-dimensional surgical simulation using osteoarthritis knees.
Placement of tibial component is expected to fulfill both maximum surface coverage and recommended anterior-posterior (AP) alignment in total knee arthroplasty (TKA). The purpose of this study is to evaluate the effect of the tibial baseplate shape on AP axis. ⋯ Symmetrically or anatomically designed tibial baseplates have their own favored AP axis and specific performance on coverage. When aligned to axis 1/3MED, anatomically designed tibial baseplates will effectively lower the mismatch rates compared to a symmetrically designed tibial baseplate. Orthopaedic surgeons are expected to place the tibial components to the cut surface during TKA with full understanding of the features between different baseplate designs, AP axes, and posterior slopes for an ideal tibial rotational position.

Observational StudyAcetabular overcoverage in the horizontal plane: an underdiagnosed trigger of early hip arthritis. A CT scan study in young adults.
Acetabular overcoverage promotes hip osteoarthritis causing a pincer-type femoroacetabular impingement. Acetabular coverage in the horizontal plane is usually poorly defined in imaging studies and may be misdiagnosed. The goal of this study was to analyze the role of acetabular overcoverage measured in the frontal plane and in the horizontal plane by CT scan and to determine its relationship with other anatomic features in the onset of hip arthritis in young adults. ⋯ Acetabular overcoverage in the horizontal plane plays an important role in the onset of early hip arthritis. Considering that this condition is usually underdiagnosed, we suggest the anterior sector acetabular angle, the posterior sector acetabular angle, and the horizontal acetabular sector angles be routinely included in decision-making algorithms in hip conservative surgery to better define hips-at-risk of developing early hip osteoarthritis.

Arthroscopic one-tunnel transosseous foveal repair for triangular fibrocartilage complex (TFCC) peripheral tear.
Arthroscopic repair of a peripheral triangular fibrocartilage complex (TFCC) tear is a promising, minimally invasive surgical technique, especially in patients with symptomatic distal radioulnar joint (DRUJ) instability. The purpose of this study was to evaluate the clinical result of arthroscopic one-tunnel transosseous foveal repair for peripheral TFCC tears. ⋯ The present study shows that arthroscopic one-tunnel transosseous repair is a good treatment strategy for TFCC foveal tears in terms of reliable pain relief, functional improvement, and re-establishment of DRUJ stability.

Reverse shoulder arthroplasty in obese patients: analysis of functionality in the medium-term.
Obesity is an epidemic nowadays and this fact conditions results in orthopaedic surgery. Very few studies evaluates if obesity is a risk factor for reverse shoulder arthroplasty. The aim of this study is to confirm if there are differences with regard to the outcomes in patients undergoing reverse shoulder arthroplasty according to their body mass index (BMI). ⋯ Functional outcomes of reverse shoulder arthroplasty are worse in patients with a BMI over 35.
