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.

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.
