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.

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.
