Prevention of motor ascending branch of the rectus femoris injuries in Bernese periacetabular osteotomy: a cadaveric study.

The Bernese periacetabular osteotomy (PAO) is a surgical procedure used to treat hip dysplasia in young adults, but it carries the risk of neurological complications, including injury to the motor ascending branch of the rectus femoris (MABRF). This study aimed to describe anatomical considerations to prevent MABRF injuries during PAO. A cadaveric study was conducted on seven specimens.

Bernese Periacetabular Osteotomy: A Comparative Study of Four Types of Incisions.

Bernese periacetabular osteotomy has diverse complications associated with incisions, such as dehiscence, hypertrophy, depression, and hyperpigmentation on scars, which affect patient satisfaction. The objective was to evaluate aesthetics and satisfaction outcomes in four different incisions. We evaluated 176 incisions in 148 patients.

Bernese periacetabular osteotomy: functional outcomes in patients with untreated intra-articular lesions.

Developmental dysplasia of the hip (DDH) has been recognized to be a condition leading to osteoarthritis. Periacetabular osteotomy (PAO) has showed good results on hip preservation treatment for these cases. Nevertheless, intra-articular damage may be responsible for persistent post-operative symptoms, so treat the articular damage before or during the PAO has emerged as an alternative to address it.

Varus mechanism is associated with high incidence of popliteal artery lesions in multiligament knee injuries.

Purpose: This study aims to identify multiple ligament knee injury patterns that possess a high-risk of vascular lesion.

Methods: We retrospectively compared torn ligament patterns and the presence of vascular lesions confirmed by magnetic resonance imaging and computed tomography angiography from 122 consecutive patients with diagnoses of multiple ligament knee injury made at the emergency department between January 2012 and December 2017. Patients were not eligible if they had an ipsilateral lower extremity lesion (dislocations or fractures at another level), initial evaluation at another hospital, or follow-up for less than 12 months.

Clinical and functional outcomes of primary total knee arthroplasty: a South American perspective.

Background: The aim of this study was to report the clinical and functional outcomes as well as complications after primary total knee arthroplasty in a cohort of Chilean patients.

Methods: We retrospectively reviewed 191 total knee arthroplasties performed in 182 patients over an 8-year period, with a minimum follow-up of 2 years. The primary outcome measure was the rate of major complications.

Total knee replacement in patients with osteoarthritis and concomitant inveterate patellar dislocation.

The inveterate patellar dislocation is an uncommon entity. The most frequent findings correspond to a misaligned valgus associated with lateral patellar dislocation. When severe knee osteoarthritis is present, total knee arthroplasty is an option, whether it is associated or not with realignment of the extensor apparatus.
