Randomized Controlled Trial
Long-term results of radial extracorporeal shock wave treatment for chronic plantar fasciopathy: A prospective, randomized, placebo-controlled trial with two years follow-up.
Numerous randomized controlled trials (RCTs) demonstrated efficacy and safety of extracorporeal shock wave therapy (ESWT) for chronic plantar fasciopathy (cPF). However, only two such RCTs investigated a follow-up period of more than 1 year, both applying focused ESWT. Corresponding data for radial ESWT (rESWT) have not yet been reported. ⋯ These data indicate that rESWT is effective and safe for the management of cPF with long-term follow-up of 2 years. © 2016 Orthopaedic Research Society.

Randomized Controlled Trial
Effect of radial shock wave therapy for carpal tunnel syndrome: A prospective randomized, double-blind, placebo-controlled trial.
Three recent studies demonstrated the positive effect of extracorporeal shock wave therapy (ESWT) for treating carpal tunnel syndrome (CTS). However, none have entirely proved the effects of ESWT on CTS because all studies had a small sample size and lacked a placebo-controlled design. Moreover, radial ESWT (rESWT) has not been used to treat CTS. ⋯ This is the first study to assess rESWT in a randomized placebo-controlled trial and demonstrate that rESWT is a safe and effective method for relieving pain and disability in patients with CTS. © 2015 Orthopaedic Research Society.

Randomized Controlled Trial Comparative Study
The effect of different types of insoles or shoe modifications on medial loading of the knee in persons with medial knee osteoarthritis: a randomised trial.
Many conservative treatments exist for medial knee osteoarthritis (OA) which aims to reduce the external knee adduction moment (EKAM). The objective of this study was to determine the difference between different shoes and lateral wedge insoles on EKAM, knee adduction angular impulse (KAAI), external knee flexion moment, pain, and comfort when walking in individuals with medial knee OA. Seventy individuals with medial knee OA underwent three-dimensional walking gait analysis in five conditions (barefoot, control shoe, typical wedge, supported wedge, and mobility shoe) with pain and comfort recorded concurrently. ⋯ A significant reduction in latter stance EKAM was seen in the lateral wedge insoles compared to the other conditions, with only the barefoot condition reducing the external knee flexion moment. However, the mobility shoe showed significant immediate knee pain reduction and improved comfort scores. Different lateral wedge insoles show comparable reductions in medial knee loading and in our study, the mobility shoe did not affect medial loading.

Randomized Controlled Trial
Effects of steroids on thrombogenic markers in patients undergoing unilateral total knee arthroplasty: a prospective, double-blind, randomized controlled trial.
Venous thromboembolism (VTE) remains an important complication after total knee arthroplasty (TKA). Systemic thrombin generation starts perioperatively. Inflammation, characterized by a rise in interleukin-6 (IL6), initiates the coagulation cascade, but low-dose steroids can reduce post-TKA IL6 levels. ⋯ The mean rise in PF1.2 in the control group was significantly greater compared to the study group (672 ± 173 pMol/L vs. 350 ± 211 pMol/L, p < 0.001). Mean PAP was higher in the study group at 4 h (1639 ± 823 µg/L vs. 1087 ± 536 µg/L), but did not reach statistical significance (p = 0.07). These results may have clinical implications in terms of postoperative VTE risk and management.

Randomized Controlled Trial Comparative Study
Sensitivity of gait parameters to the effects of anti-inflammatory and opioid treatments in knee osteoarthritis patients.
The study aim was to address the need for objective markers of pain-modifying interventions by testing the hypothesis that selective gait measures of knee joint loading can distinguish differences between non-steroidal anti-inflammatory (NSAID), analgesic treatment (opioid-receptor agonist), and placebo in patients medial knee osteoarthritis (OA). A randomized, single-blind washout, double-blind treatment, double-dummy cross-over trial using three treatment arms placebo, opioid (Oxycodone), and NSAID (Celecoxib) in medial compartment knee OA patients. Six patients with Kellgren-Lawrence radiographic severity grades of 2 or 3 completed six testing sessions (gait and pain assessment) at 2-week intervals. ⋯ Self-reported function (WOMAC scores) was not different among treatments (p>0.05). The changes in total reaction moments and GRFs for only the NSAID suggest that greater increases in joint loading occurs when joint inflammation is treated in addition to pain. The total knee reaction moment, representing the magnitude of the extrinsic moment, appears to be a sensitive marker, more so than self-reported metrics, for evaluating knee OA treatment effects.
