Peri-prosthetic joint infection (PJI) is one of the most serious and dreaded complications after total joint replacement (TJR). Due to an aging population and the constant rise in demand for TJR, the incidence of PJI is also increasing. Successful treatment of PJI is challenging and is associated with high failure rates. ⋯ In order to translate phage therapy to treat PJI in clinics, further preclinical testing is still required to study optimal delivery methods as well as the interaction between phage and the immune system in vivo. © 2017 Orthopaedic Research Society.

Review Meta Analysis Comparative Study
Unilateral versus bilateral percutaneous kyphoplasty for osteoporotic vertebral compression fractures: A systematic review and meta-analysis of RCTs.
The purpose of this research was to compare the efficacy and safety of unilateral versus bilateral PKP for osteoporotic vertebral compression fractures (OVCFs). Six databases (Cochrane, PubMed, MEDLINE, EMBASE, SinoMed, and CNKI) were searched without language restrictions. Twelve randomized controlled trials involving a total of 1,030 patients were identified. ⋯ There were no differences in complications such as cement leakage and adjacent vertebral fractures between two approaches (p = 0.06 and p = 0.97, respectively). Life quality assessment (SF-36) indicates unilateral PKP had a better result of bodily pain relief (p < 0.05; 95%CI = 3.93 to 7.48) and general health benefit (p < 0.05; 95%CI = 0.02 to 2.93) with short-term follow-up after operation. We suggest that a unilateral PKP is advantageous.

As human lifespan increases so does the incidence of age-associated degenerative joint diseases, resulting in significant negative socioeconomic consequences. Osteoarthritis (OA) and intervertebral disc degeneration (IDD) are the most common underlying causes of joint-related chronic disability and debilitating pain in the elderly. Current treatment methods are generally not effective and involve either symptomatic relief with non-steroidal anti-inflammatory drugs and physical therapy or surgery when conservative treatments fail. ⋯ Studies over the past decades have uncovered a number of important molecular and cellular changes in joint tissues with age. However, the precise causes of damage, cellular targets of damage, and cellular responses to damage remain poorly understood. The objectives of this review are to provide an overview of the current knowledge about the sources of endogenous and exogenous damaging agents and how they contribute to age-dependent degenerative joint disease, and highlight animal models of accelerated aging that could potentially be useful for identifying causes of and therapies for degenerative joint diseases.
