Randomized Controlled Trial Comparative StudyUltrashort versus Conventional Anatomic Cementless Femoral Stems in the Same Patients Younger Than 55 Years.
Because the clinical and radiographic performance of an ultrashort anatomic cementless stem has been investigated in only two randomized controlled studies, well-designed trials should aim for a thorough comparison of the outcomes of ultrashort anatomic cementless and conventional anatomic cementless stems. ⋯ Level I, therapeutic study.

Multicenter StudyReliability and Validity of a Japanese-language and Culturally Adapted Version of the Musculoskeletal Tumor Society Scoring System for the Lower Extremity.
The Musculoskeletal Tumor Society (MSTS) scoring system is a widely used functional evaluation tool for patients treated for musculoskeletal tumors. Although the MSTS scoring system has been validated in English and Brazilian Portuguese, a Japanese version of the MSTS scoring system has not yet been validated. ⋯ The Japanese-language translation of the MSTS scoring system for the lower extremity has sufficient reliability and reasonable validity. Nevertheless, the observation of a ceiling effect suggests poor ability of this system to discriminate from among patients who have a high level of function.

ReviewMedical School Experiences Shape Women Students' Interest in Orthopaedic Surgery.
Orthopaedic surgery now has the lowest percentage of women in residency programs of any surgical specialty. Understanding factors, particularly those related to the medical school experience, that contribute to the specialty's inability to draw from the best women students is crucial to improving diversity in the profession. ⋯ Successful recruitment of women to orthopaedic surgery may be improved by early exposure and access to role models, both of which will help women students' perceptions of their role in field of orthopaedic surgery.

Comparative StudyHip, Knee, and Ankle Osteoarthritis Negatively Affects Mechanical Energy Exchange.
Individuals with osteoarthritis (OA) of the lower limb find normal locomotion tiring compared with individuals without OA, possibly because OA of any lower limb joint changes limb mechanics and may disrupt transfer of potential and kinetic energy of the center of mass during walking, resulting in increased locomotor costs. Although recovery has been explored in asymptomatic individuals and in some patient populations, the effect of changes in these gait parameters on center of mass movements and mechanical work in patients with OA in specific joints has not been well examined. The results can be used to inform clinical interventions and rehabilitation that focus on improving energy recovery. ⋯ The fatigue and limited physical activity reported in patients with lower extremity OA could be associated with increased mechanical work of the center of mass. Focused gait retraining potentially could improve walking mechanics and decrease fatigue in these patients.
