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.

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.

Return to sports after hip resurfacing versus total hip arthroplasty: a mid-term case control study.
Hip resurfacing (HR) is an alternative to conventional total hip arthroplasty (THA) for the treatment of osteoarthritis (OA) in very active, young male patients. However, there is no study in the literature that has proven its benefits for high-impact sport over standard primary THA. The aim of the current study was to investigate the return to sport and function level of male patients after THA vs. HR. ⋯ HR patients showed a significantly higher High-activity arthroplasty score (HAAS) (14.9 vs. 12.9, p < 0.001) and Lower extremity activity scale (LEAS) (15.9 vs. 14.1, p < 0.001) and reached significantly higher values in the Hip cycle score (HCS) (44.7 vs. 35.7 p = 0.037) and Impact score (IS) (40.9 vs. 29.6, p < 0.002) than THA patients. No significant differences were found in the HOOS function section (91.4 vs. 90.3, p = 0.803) and the Pain numeric rating scale (NRS)-11 (0.6 vs. 0.9 p = 0.169). Patients with HR had a slightly higher Harris hip score (HHS) (97.8 vs. 95.6, p = 0.015) CONCLUSION: The current study suggests that young male patients are able to engage in higher activity levels after HR compared to standard THA.

Patient expectation fulfilment following total hip arthroplasty: a 10-year follow-up study.
The primary aim of this study was to assess how expectation fulfilment changes up to 10 years following total hip arthroplasty (THA). ⋯ Expectation fulfilment following THA changes with time. The majority of patients report high levels of expectation fulfilment following THA at late follow-up. This information can be used to help manage the longer-term expectations of patients undergoing THA.
