Impact of change in coronal plane alignment of knee (CPAK) classification on outcomes of robotic-assisted TKA.

Background: Mechanical alignment with total knee arthroplasty (TKA) has been widely used since the implantation of the first prosthetic knee. Multiple studies have reported 80% patient satisfaction with TKA. However, the reported patients' dissatisfaction is believed to be caused by having to convert different knee alignments to neutral alignments.

Step-Cut Subtrochanteric Osteotomy Combined with Total Hip Arthroplasty for Neglected Traumatic Hip Dislocations.

Background: Total Hip Arthroplasty remains the standard treatment protocol for patients with neglected traumatic dislocations of the hip with arthritis. A total hip arthroplasty needs to be frequently combined with a subtrochanteric shortening femoral osteotomy to aid in the reduction of the hip joint in such cases. Still long-term stable implant fixation, rigid construct, and favorable functional outcome remain a challenge.

Lateral Buttress Plate Along with Cancellous Screw Fixation for Hoffa Fracture Using Swashbuckler Approach.

Coronal plane fracture of the posterior femoral condyle, Hoffa fracture is a rare injury pattern. We report a case of a 32-year-old male with closed Lateral Hoffa fracture along with patella and medial condyle of tibia fracture. Patient was treated using 02 cannulated cancellous screws and a lateral recon plate for Hoffa fracture, tension band wiring for patella fracture and 02 cannulated cancellous screws for tibia fracture through modified swashbuckler approach.

Winging of Scapula: An Uncommon Presentation of a Common Tumor.

Neuromuscular causes of winging of scapula are well known, but winging and snapping of scapula may rarely be caused by space-occupying lesion of the thoracic wall. Although osteochondroma of scapula is rare, it is the most common neoplasm of scapula, and osteochondroma of ventral scapula may lead to pseudo-winging, snapping, and rib erosion on the same side. Owing to its rarity, we report two cases of osteochondroma of ventral scapula with complains of difficult scapulothoracic movement (snapping scapula) and pseudo-winging.

Osteoblastoma of Talus: A Diagnostic Dilemma.

The critical biomechanical importance of talus and nonspecific clinical features of talus lesion warrants a meticulous diagnostic work-up for specific management, particularly when the talus lesion is associated with concomitant soft tissue and joint abnormalities. We present a rare case of osteoblastoma of talus with concomitant tenosynovitis of tibialis anterior, ankle joint effusion, varicose vein and moderate distal arterial stenosis.

Adsorption of Emerging Ionizable Contaminants on Carbon Nanotubes: Advancements and Challenges.

The superior adsorption capacity of carbon nanotubes has been well recognized and there is a wealth of information in the literature concerning the adsorption of unionized organic pollutants on carbon nanotubes. Recently, the adsorption of emerging environmental pollutants, most of which are ionizable, has attracted increasing attention due to the heightened concerns about the accumulation of these emerging contaminants in the environment. These recent studies suggest that the adsorption of emerging ionizable contaminants on carbon nanotubes exhibit different characteristics than unionized ones.
