BACKGROUND CONTEXT: Obesity's impact on standing sagittal alignment remains poorly understood, especially with respect to the role of the lower-limbs. Given energetic expenditure in standing, a complete understanding of compensation in obese patients with sagittal malalignment remains relevant. PURPOSE: This study compares obese and non-obese patients with progressive sagittal malalignment for differences in recruitment of pelvic and lower limb mechanisms. STUDY DESIGN/SETTING: Single center retrospective review...

: Patellofemoral instability is a painful and commonly recurring condition, which often must be managed surgically. Diagnosis can be aided by the use of a variety of physical exam signs, such as the Q angle, Beighton hypermobility score, glide test, J sign, patellar tilt test, and apprehension test. Imaging modalities including x-ray, CT, and MRI guide both diagnosis and management by revealing trochlear dysplasia, bony malalignment, and ligamentous injury that contribute to instability...

: Recent reports suggest that uncemented total hip replacement arthroplasty (THR) results in favorable short- to mid-term clinical results. In the present study, we assessed the mid-term clinical results of VerSys Hip System uncemented THR at our hospital. MATERIALS AND METHODS: We studied patients who received THR using VerSys Hip System and who could be followed-up more than 3 years. Clinical records were used to retrospectively identify patient characteristics, which included age, gender, disease requiring THR, preoperative and postoperative pain score of the Japan Orthopaedic Association scoring system, range of motion in flexion and abduction, operating time, intraoperative complication, and additional operation or revision surgery...

BACKGROUND CONTEXT: Many radiological parameters have been reported to correlate with patient's disability including sagittal vertical axis (SVA), pelvic tilt (PT), and pelvic incidence minus lumbar lordosis (PI-LL). European literature reports other parameters such as lumbar lordosis index (LLI) and the global tilt (GT). If most parameters correlate with health-related quality of life scores (HRQLs), their impact on disability remains unclear. PURPOSE: This study aimed to validate these parameters by investigating their correlation with HRQLs...

BACKGROUND: Proper alignment of total knee arthroplasty (TKA) is essential for TKA function and may reduce the risk of aseptic failure. Technologies that prevent malalignment may reduce the risk of revision surgery. QUESTIONS/PURPOSES: The purpose of this study was to compare two competing TKA systems that purport improved alignment: patient-specific instrumentation (PSI), and a handheld portable navigation device (NAV). METHODS: After IRB approval, 49 consecutive PSI TKAs (40 patients) were matched based on preoperative characteristics to 49 NAV TKAs (40 patients) performed by a single surgeon...

REVIEW
Abhishek Abhishek, Michael Doherty
Calcium pyrophosphate crystal deposition (CPPD) associates with ageing, osteoarthritis (OA), uncommon metabolic diseases, mutations and polymorphisms in the ankylosis human gene (ANKH). CPPD is frequently polyarticular, occurs due to a generalised articular predisposition, and the association between CPPD and OA is joint specific, for example CPPD associates with knee OA, but not with hip OA. Other recently identified associations include knee malalignment (knee CC), low cortical BMD and soft-tissue calcification...

BACKGROUND: Although the tangential sesamoid view is used to visualize the sesamoid position relative to the first metatarsal head, correctly evaluating patients with severe varus of the first metatarsal is difficult. Computed tomography (CT) can be helpful due to its cross-sectional images in any plane. The purposes of this study were to evaluate the alignment of the tibial sesamoid and investigate the relationship between malalignment and degenerative change in the sesamoid metatarsal joint (SMJ) using simulated weight-bearing CT imaging in patients with hallux valgus...

BACKGROUND: Little is known about clinical outcomes after revision meniscal allograft transplantation (RMAT), and there are no studies on magnetic resonance imaging (MRI) evaluations during the early remodeling period. HYPOTHESIS: The objective imaging results, as determined by MRI evaluation, would be inferior to those of published data on primary meniscal allograft transplantations (MATs), although short-term clinical improvement would be achieved after RMAT. STUDY DESIGN: Case series; Level of evidence, 4...

BACKGROUND: The essential static patellar stabilizer is a normal-shaped trochlear groove. A dysplastic groove destabilizes the patella. Trochleoplasty approaches this underlying condition and reshapes the trochlea. However, studies have reported on trochleoplasty for revision cases or as accompanied by other interventions. The effect of trochleoplasty alone remains unexplained. PURPOSE: To introduce trochleoplasty as a stand-alone treatment for recurrent patellar dislocation and to compare its pre- to postoperative functional and clinical variables...

PURPOSE: Regarding the close interaction between the spinal alignment and the pelvis orientation, no parameter is routinely used to describe and to evaluate the global spinopelvic balance, taking into account simultaneously the spinal part and the pelvic part of the global alignment. We described the global tilt (GT) that could analyze malalignment considering the spine and the pelvis simultaneously. From a geometrical point of view, the global tilt is the sum of the pelvic tilt (PT) and the C7 vertical tilt (angular value of sagittal vertical axis)...

Guan-Yang Song, Xin Liu, Hui Zhang, Qian-Qian Wang, Jin Zhang, Yue Li, Hua Feng
BACKGROUND: A special type of meniscal lesion involving the peripheral attachment of the posterior horn of the medial meniscus (PHMM), termed ramp lesion, is commonly associated with anterior cruciate ligament (ACL) injury. However, no study has investigated its anatomic risk factors. Recently, increased meniscal slope has been identified as an independent anatomic risk factor for noncontact ACL injury. HYPOTHESIS: Increased medial meniscal slope (MMS) as measured on magnetic resonance imaging (MRI) will correlate with greater risk of concomitant ramp lesion in noncontact ACL injury...

OBJECTIVES: Initial stability of tibial trays is crucial for long-term success of total knee arthroplasty (TKA) in both primary and revision settings. Rotating platform (RP) designs reduce torque transfer at the tibiofemoral interface. We asked if this reduced torque transfer in RP designs resulted in subsequently reduced micromotion at the cemented fixation interface between the prosthesis component and the adjacent bone. METHODS: Composite tibias were implanted with fixed and RP primary and revision tibial trays and biomechanically tested under up to 2...
