How Common is Subsequent Posterior Tibial Tendon Dysfunction or Tarsal Tunnel Syndrome After Ankle Sprain Injury?
The objective of this study was to investigate the incidence of PTTD and TTS in the 2 years following an ankle sprain and which variables are associated with its onset. In total, 22,966 individuals in the Military Health System diagnosed with ankle sprain between 2010 and 2011 were followed for 2 years. The incidence of PTTD and TTS after ankle sprain was identified. Binary logistic regression was used to identify potential demographic or medical history factors associated with PTTD or TTS. In total, 617 (2.7%) received a PTTD diagnosis and 127 (0.6%) received a TTS diagnosis. Active-duty status (odds ratio [OR] 2.18, 95% ...

Radiographic Evidence of Early Posttraumatic Osteoarthritis following Tibial Plateau Fracture Is Associated with Poorer Function
J Knee Surg DOI: 10.1055/s-0042-1755375To determine if radiographic evidence of posttraumatic osteoarthritis (PTOA) following tibial plateau fracture correlates with poorer clinical and functional outcomes, patients with tibial plateau fractures were followed at 3, 6, and 12 months. All patients had baseline radiographs and computed tomography scan. Radiographs obtained at each follow-up were reviewed for healing, articular incongruence, hardware positional changes, and the development of postinjury arthritic change. Cohorts were determined based on the presence (PTOA) or absence (NPTOA) of radiographic evidence of PTOA. D...

A Population-Level Summary of Health Care Utilization for the Management of Patellar Tendinopathy in the Military Health System
J Knee Surg DOI: 10.1055/s-0042-1751266Patellar tendinopathy (PT) is a common nontraumatic orthopaedic disorder of the knee suffered by many service members. Understanding the make-up of usual care for PT at the system level can better frame current clinical gaps and areas that need improvement. Exercise therapy is recommended as a core treatment for PT, but it is unclear how often it is used as a part of usual care for PT within the Military Health System (MHS). The purpose of the study was to identify interventions used in the management of PT and the timing of these interventions. A secondary purpose was to determine if...
