The role of physiatry in regenerative medicine: the past, the present, and future challenges.

Historically, the foundation of physical medicine and rehabilitation training has provided the capabilities to optimize nonoperative treatments of a variety of musculoskeletal conditions, including acute and chronic muscle, tendon, ligament, and cartilage disorders. Such treatments include the use of nonsteroidal anti-inflammatory drugs (NSAIDs), therapeutic modalities (eg, thermal and manual therapies), and corticosteroid injections in conjunction with specific rehabilitation exercises. Although NSAIDs, modalities, and corticosteroids may be helpful for short-term pain reduction and early recovery of function, they do not typically reverse the structural changes associated with degenerative conditions and may contribute to worse long-term outcomes by potentially interfering with tissue healing.

Basic principles regarding strength, flexibility, and stability exercises.

Strength, flexibility, and stability are physiologic parameters associated with health-related physical fitness. Each of these domains affects health in general, the risk of injury, how an injury is treated, and performance in activities of daily living and sports. These domains are affected by individual phenotype, age, deconditioning, occupational activity, and formal exercise.

The effects of blood and fat on Morse taper disassembly forces.

Biological debris between modular components using Morse tapers in hip arthroplasty can lead to weakening of the implant construct. We conducted a study to determine the effect of blood and fat within the taper interface. Tapers were divided into groups 1 (clean), 2 (surface covered with blood and fat), and 3 (blood and fat wiped off).
