Previous reviews have reported that manifestations of pain sensitization may play an important role in the pain experienced by people with knee osteoarthritis. However, it is unknown if manifestations of pain sensitization are common features across other painful knee disorders or if sensitization requires targeted intervention. This review aims to synthesize the published research investigating manifestations of pain sensitization in painful knee disorders and to evaluate if the manifestations of pain sensitization change in response to treatment. ⋯ Our meta-analysis provides evidence of pain sensitization in people with knee osteoarthritis (strong evidence), people with patellofemoral pain (moderate evidence), and postmeniscectomy patients (very limited evidence). However, conflicting evidence exists in patellar tendinopathy. Metaregression indicates that pain is associated with pressure pain thresholds in knee osteoarthritis. In people with knee osteoarthritis and patellofemoral pain, several interventions were found to reduce manifestations of pain sensitization. This review highlights that pain sensitization may be amenable to treatment through exercise therapy, mobilization, and pharmacological and surgical intervention.

Meta Analysis
Effectiveness of Slump Stretching on Low Back Pain: A Systematic Review and Meta-analysis.
The slump test is a type of neurodynamic test that is believed to evaluate the mechanosensitivity of the neuromeningeal structures within the vertebral canal. The objective of this review was to investigate the effectiveness of slump stretching on back pain and disability in patients with low back pain (LBP). ⋯ There is very low to moderate quality of evidence that slump stretching may have positive effects on pain in people with LBP. However, the quality of evidence for the benefits of slump stretching on disability was very low. Finally, it appears that patients with nonradicular LBP may benefit most from slump stretching compared with other types of LBP.

Randomized Controlled Trial Multicenter Study
Effects of Electroacupuncture on Opioid Consumption in Patients with Chronic Musculoskeletal Pain: A Multicenter Randomized Controlled Trial.
To evaluate the efficacy and safety of electroacupuncture in reducing opioid consumption in patients with chronic musculoskeletal pain. ⋯ It is safe to reduce opioid medication use in patients with chronic pain. Due to the small sample size, we could not confirm if electroacupuncture offers extra benefit in addition to education. This nondrug therapy could be a promising adjunct to facilitate opioid tapering in patients who are willing to reduce opioids.

Randomized Controlled Trial Multicenter Study
Intra-articular Steroids vs Saline for Lumbar Z-Joint Pain: A Prospective, Randomized, Double-Blind Placebo-Controlled Trial.
To determine if intra-articular (IA) injection of corticosteroids is effective in reducing the need for radiofrequency ablation (RFA) in those with dual comparative medial branch block (MBB)-confirmed lumbar z-joint pain. ⋯ Intra-articular corticosteroids were not effective in reducing the need for or the time to a radiofrequency ablation of the medial branches in those with dual MBB-confirmed lumbar z-joint pain.

Randomized Controlled Trial Comparative Study
Comparison of Ultrasound-Guided Local Ozone (O2-O3) Injection vs Corticosteroid Injection in the Treatment of Chronic Plantar Fasciitis: A Randomized Clinical Trial.
Plantar fasciitis (PF) is one of the most common causes of heel pain. The affected area is often close to the attachment of plantar fascia to calcaneus bone. The purpose of this study was to compare the effects of ozone (O2-O3) injection to corticosteroid injection under ultrasound guidance for the treatment of chronic PF. ⋯ Both methods were effective in the treatment of chronic PF. Steroid injection provided a more rapid and short-term therapeutic effect. However, ozone (O2-O3) injection led to a slow and longer-lasting treatment outcome. Ozone (O2-O3) injection can be an effective treatment, with slow onset and a longer durability in the treatment of chronic PF.
