The effects of soft tissue lateral release on the stability of the ligament complex of the knee.
Valgus deformity presents a particular challenge in total knee arthroplasty. This condition regularly leads to contractures of the lateral capsular ligament complex and to overstretching of the medial ligamentous complex. Reconstruction of the knee joint kinematics and anatomy often requires lateral release. However, data on how such release weakens the stability of the knee are missing in the literature. This study investigated the effects of sequential lateral release on the collateral stability of the ligament complex of the knee in vitro. ⋯ Our study shows for the first time the association between sequential lateral release and stability of the ligamentous complex of the knee. To maintain the stability, knee surgeons should avoid releasing the entire lateral collateral ligament, which would significantly decrease stability in the lateral compartment.

Acetabular retroversion in dysplastic hips is associated with decreased 3D femoral head coverage independently from lateral center-edge angle.
The clinical significance of acetabular retroversion in non-dysplastic hips can be explained as pincer-type femoroacetabular impingement (FAI), whereas that in dysplastic hips is not clarified because FAI normally poses little problems for dysplastic hips. We aimed to evaluate three-dimensional (3D) femoral head coverage in dysplastic hips with and without acetabular retroversion and to elucidate the role of acetabular retroversion on the 3D femoral head coverage. ⋯ Acetabular retroversion in dysplastic hips was associated with decreased 3D femoral head coverage independently from lateral center-edge angle. The age at surgery in the retroversion group was significantly younger, suggesting a relationship between decreased 3D coverage and potentially earlier symptom onset.

Efficacy of total hip arthroplasty after operatively treated acetabular fracture.
We evaluated the clinical and radiological outcomes of patients following total hip arthroplasty (THA) for acetabular fracture. ⋯ THA secondary to an operatively treated acetabular fracture provides good symptomatic relief, but shows relatively inferior survival rates, and clinical failure was related to post-traumatic arthritis with acetabular non-union.

"Cat and dog bite injuries of the hand: early versus late treatment".
Animal bites of the hand are common injuries in the emergency department. Serious complications may occur if those injuries are not treated adequately. The purpose of the study was to examine if there is a difference between the treatment of animal bite injuries at an early stage (first treatment within the first 24 h after injury, group I) versus a later stage (first treatment more than 24 h after injury, group II) retrospectively. ⋯ Level 3, therapeutic.

Massive graft resorption after iliac crest allograft reconstruction for glenoid bone loss in recurrent anterior shoulder instability.
Donor site morbidity constitutes the most prevalent source of complications during anatomic glenoid reconstruction. Therefore, the aim of this study was to evaluate the clinical and radiologic results of arthroscopic anatomic glenoid reconstruction using an allogenic, tricortical iliac crest bone graft for glenoid bone loss in recurrent anterior shoulder instability. ⋯ Level IV, case series, therapeutic study.
