[Evidence-Based Treatment and Differential Diagnoses of Olecranon Bursitis].

Evidence-Based Treatment and Differential Diagnoses of Olecranon Bursitis Bursitis olecrani is a common clinical diagnosis that can have systemic, infectious and traumatic causes. In this article we want to present the diagnostics, possible differential diagnoses, complications and the current therapy recommendations as a practical guide.

[Pain after Shoulder Prosthesis Is Not Always Due to Infection or Loosening].

Pain after Shoulder Prosthesis Is Not Always Due to Infection or Loosening Summary: Suprascapular nerve neuropathy is becoming increasingly recognized as a reason for persistent shoulder pain. The underlying cause may be iatrogenic, as in the case of our patient, or due to ganglionic compression or traction. Unfortunately, diagnosis and thus adequate therapy is frequently delayed.

Early Outcomes of Adolescent ACL Reconstruction With Hybrid Hamstring Tendon Autograft-Allograft Versus Hamstring Tendon Autograft Alone.

Background: Small-diameter semitendinosus-gracilis tendon autografts may be encountered intraoperatively during anterior cruciate ligament reconstruction (ACLR); these have been shown to be at increased risk of graft rupture. One option that surgeons have pursued to reduce the theoretical failure rate of these smaller-diameter grafts is augmenting them with allograft material, thereby forming a larger-diameter hybrid autograft-allograft construct.

Purpose/hypothesis: The purpose of this study was to compare outcomes in adolescent athletes of primary ACLR using a hybrid autologous hamstring tendon and soft tissue allograft construct versus ACLR using small-diameter hamstring tendon autograft.

Trochleoplasty improves knee flexion angles and quadriceps function during gait only if performed bilaterally.

Purpose: To investigate if a trochleoplasty increases knee flexion angles and extensor moments in the gait of patients with patellar instability and to compare postoperative gait to a healthy control group.

Methods: A bilateral dislocation group (6 patients) and a unilateral dislocation group (14 patients) were treated with bilateral and unilateral trochleoplasty, respectively. Kinematics and kinetics of the lower extremity were captured using 3D-gait analysis (VICON, 12 cameras, 200 Hz, plug-in-gait, two force plates).

Recurrent patellar dislocations in adolescents result in decreased knee flexion during the entire gait cycle.

Purpose: To evaluate the kinematics/kinetics of the ankle, knee, hip in the sagittal plane in adolescents with recurrent patellar dislocation in comparison to a healthy control.

Methods: Case-control study. Eighty-eight knees (67 patients) with recurrent patellar dislocation (mean age 14.
