Objectives: Acquired lymphedema of upper extremity is a chronic pathologic status that frequently occurs after breast cancer treatment. Reliable and quantitative evaluation of lymphedema is crucial for successful management of patients. Although lymphoscintigraphy is the primary investigation for the confirmation and evaluation of lymphedema, the specific protocol of stress intervention is not well established.

- The study aimed to improve the prediction of pathologic complete response (pCR) in breast cancer using MRI and ultrasound-guided biopsies after neoadjuvant chemotherapy (NAC).
- A total of 40 patients with nearly pCR underwent ultrasound-guided biopsies followed by surgery, revealing that pCR was confirmed in 67.5% of cases, with notable predictive values for the biopsy methods.
- The research suggests that using MRI criteria with ultrasound-guided biopsies can reliably identify patients who might safely avoid surgery after NAC, paving the way for future larger clinical trials.
Mechanoreceptor profile of the lateral collateral ligament complex in the human elbow.

Article Synopsis
- The lateral collateral ligament complex (LCLC) in the elbow provides essential joint stability and contains mechanoreceptors that play a protective role in preventing instability, particularly during activities that involve rotation.
- This study examined LCLCs extracted from cadaver elbows to evaluate the presence and arrangement of mechanoreceptors like Golgi, Ruffini, and Pacinian corpuscles, finding that Ruffini corpuscles had the highest density.
- The findings suggest that the distribution of these mechanoreceptors is crucial for proprioception, which may improve the outcomes of elbow ligament reconstruction surgeries.
The different role of each head of the triceps brachii muscle in elbow extension.
Acta Orthop Traumatol Turc
May 2018
Objective: The aim of this study was to investigate the functional role of each head of the triceps brachii muscle, depending on the angle of shoulder elevation, and to compare each muscle force and activity by using a virtual biomechanical simulator and surface electromyography.
Methods: Ten healthy participants (8 males and 2 females) were included in this study. The mean age was 29.
[Purpose] The purpose of this study was to examine the association between muscle-strengthening exercises applied to the knee extensor muscles and the maintenance of standing balance in both, the anteroposterior and mediolateral directions in patients who had undergone total knee replacement. [Subjects and Methods] Thirty patients who underwent total knee replacement with bilateral artificial joints participated in this study. During the eight-week study period, the load on the knee extensors was gradually increased, and the standing balance ability was measured by differentiating the anteroposterior and mediolateral directions both, before and after the experimental period.

[Purpose] The purpose of this study was to examine the relationship between standing balance increased through muscle-strengthening exercises and pain in knee osteoarthritis patients. [Subjects and Methods] Thirty knee osteoarthritis patients were equally divided into a strengthening exercise group and an unstable exercise group. Before and after the six-week experiment, the visual analogue scale was measured, and bilateral one-leg standing tests were performed.

Methods: From 1996 to 2012, among 290 knees that underwent meniscal allograft transplantation and received follow-up examination for more than 1 year, those knees that underwent second-look arthroscopy were reviewed. Patients with no postoperative MRI and patients with a time gap between postoperative MRI and second-look arthroscopy of more than 3 months were excluded.
