Impact of Range of Motion Trajectory on Patient-Reported Outcomes Following Total Knee Arthroplasty.

Background: Postoperative knee range of motion (ROM) is among the most frequently reported functional metrics following total knee arthroplasty (TKA). Despite the major use of ROM as a metric, minimal literature exists assessing the progression of motion postoperatively over time or its implications on patient-reported outcome measures. As such, this study aimed to: (1) determine the recovery trajectory in knee ROM during the first year following primary TKA; and (2) determine if a correlation existed between patients' ROM recovery trajectory and patient-reported outcome measure scores.

Can fluoxetine mitigate mental health decline in musculoskeletal trauma patients: a pilot single-center randomized clinical trial.

Background: Musculoskeletal trauma is one of the leading causes of disability in the USA and its negative quality of life impact extends beyond that of physical recovery. More than 50% of victims of musculoskeletal trauma suffer lasting mental health issues and post-traumatic stress disorder (PTSD) symptomology following their injury. These symptoms can develop across all spectrums of patients and are independent predictors of poor outcome.

Forearm flexor injury is associated with medial ulnar collateral ligament injury in throwing athletes.

Background: Elbow ulnar collateral ligament (UCL) injuries have become increasingly common in throwing athletes. The forearm flexors (FF) have been studied as biomechanical stabilizers for the medial elbow. However, there are no studies investigating the association of concomitant UCL injuries and FF injuries in throwing athletes.

The V-Sign: A Simple Radiographic Sign of Shoulder Subluxation.

Introduction Shoulder subluxation is a common finding associated with orthopedic pathology. This study assesses the inter- and intra-observer reliability of a new radiographic sign used to identify glenohumeral subluxation. Methods Shoulders of 55 consecutive patients presenting with shoulder pain were reviewed for the presence of a "V-sign".

Assessment of the craniocaudal stability of four extracapsular stabilization techniques during two cyclic loading protocols: a cadaver study.

Objective: To (1) compare the effect of cyclic loading on craniocaudal tibial translation in cranial cruciate ligament (CrCL)-deficient stifles after extracapsular stabilization, and (2) evaluate the effect of peak force during cyclic loading on the rate of development of craniocaudal laxity.

Study Design: Biomechanical cadaveric study.

Sample Population: Cadaveric pelvic limbs (n = 24 pairs) from skeletally mature dogs.

Negative effects of smoking, workers' compensation, and litigation on pain/disability scores for spine patients.

Background: When initiating treatment for patients with spinal disorders, we examined the impact of smoking, workers compensation, and litigation on disability and pain scores.

Methods: With Institutional Review Board approval, the medical records of 13,704 consecutive patients with spinal disorders treated at two university spine centers were reviewed. Particular attention was focused on the pretreatment impact of three variables: smoking, workers compensation, and litigation.

Eliminating log rolling as a spine trauma order.

Background: Currently, up to 25% of patients with spinal cord injuries may experience neurologic deterioration during the initial management of their injuries. Therefore, more effective procedures need to be established for the transportation and care of these to reduce the risk of secondary neurologic damage. Here, we present more acceptable methods to minimize motion in the unstable spine during the management of patients with traumatic spine injuries.

Grade 2 chondrosarcoma: stage I or stage II tumor?

We analyzed chondrosarcomas of bone to assess whether Grade 2 tumors are more appropriately grouped with Grade 1 chondrosarcomas or Grade 3 and dedifferentiated chondrosarcomas (Musculoskeletal Tumor Society Stage I or Stage II). A retrospective chart review identified 109 patients who presented with nonmetastatic chondrosarcoma. Data were gathered on each tumor's histologic grade, extent (intracompartmental versus extracompartmental), resection margin status, and site (axial versus appendicular).

Humeral retroversion and its relationship to glenohumeral rotation in the shoulder of college baseball players.

Background: Previous studies have documented changes in musculature, bony anatomy, and glenohumeral rotation in the dominant shoulder of baseball players.

Hypothesis: In a group of asymptomatic college baseball players the total range of motion in the dominant and nondominant shoulders will be similar. Any measured increase in external rotation and decrease in internal rotation occurring between the two sides will be consistent and directly correlate with an increased angle of humeral retroversion in the dominant extremity.
