Atypical location of an osteoid osteoma with atypical anterior knee pain.

Introduction: An osteoid osteoma is a painful tumor that most commonly affects the extra-articular parts of the long bones. An intra-articular location of an osteoid osteoma is rare. Various differential diagnoses may arise in connection with such an unusual location because it causes atypical clinical signs.

Functional outcomes of repair of Achilles tendon using a biological open surgical method.

Objective: The aim of this study was to evaluate the mid-term functional outcomes of ankles following biological open Achilles tendon repair and early postoperative mobilization.

Methods: The study retrospectively evaluated 22 male patients who underwent one-sided biological open Achilles tendon repair. The American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot score, isokinetic muscle strength and endurance tests and active angle reproduction test at 15° of dorsiflexion and 20° of plantarflexion of the injured and uninjured sides were measured and compared.

Mid-term results of Oxford Phase 3 unicompartmental knee arthroplasty in obese patients.

Objective: The aim of this study was to evaluate the mid-term outcomes of Oxford Phase 3 unicompartmental knee arthroplasty (UKA) in obese patients in terms of prosthesis survival, progression of lateral compartment arthrosis and functional outcomes.

Methods: The study included 67 patients, with a body mass index over 30, treated with mobile bearing Oxford Phase 3 UKA for isolated medial osteoarthritis between January 2005 and December 2010. Preoperative and postoperative knee range of motion (ROM) and knee scores (Hospital for Special Surgery, HSS and Oxford knee scores) were compared.

Aortic elastic properties in athletes using anabolic-androgenic steroids.

The use of anabolic-androgenic steroids (AAS) has been linked to acute cardiovascular events in athletes. The purpose of the present study was to investigate the aortic elastic properties in athletes who had been self-administering AAS compared with a group of athletes not using these drugs. Fourteen male bodybuilders using AAS and 27 male wrestlers (non-users) volunteered to the study.

Discrimination between physiologic and pathologic left ventricular dilatation.

The identification of certain cardiovascular disease in athletes may constitute the basis for disqualification from competition in an effort to minimize the risk of sudden cardiac death. The aim of this study was to assess diastolic and systolic parameters measured by tissue Doppler imaging in endurance veteran athletes who had prominent cardiac dilatation and patients with idiopathic dilated cardiomyopathy in order to determine whether these variables might differentiate each other.
