The ACL reconstruction with hamstring tendons has become increasingly popular, in part because it is assumed that the complication rate associated with the technique and their severity are lower than with patellar tendon. Two cases of stress reaction of the medial supracondylar area of the femur after ACL reconstruction with hamstring tendons using BioTransfix (Arthrex, Naples, FL, USA) devices for fixation within femur are presented. Both patients were professional athletes (one soccer and one basketball player), and it is hypothesized that the accelerated rehabilitation program used might have represented a risk factor for stress fractures when associated with the guide pin exit hole in the medial femoral cortex. To our knowledge, no such cases have been published to date, but it is important to consider this possibility if an unexplained pain arises in the rehabilitation process of an ACL reconstruction using transfemoral fixation.

We present the case of a 64-year-old female patient who had a traumatic dislocation of a reversed shoulder arthroplasty that was unnoticed for 5 weeks and that was reduced arthroscopically. Arthroscopy of the shoulder, as in other joints with prostheses, can facilitate the treatment of conditions that would otherwise require the use of open surgery to solve them and that might become more frequent because of the widespread use of reversed shoulder arthroplasties, which have a high rate of dislocation.
