Patients 65 years or older of age markedly improved from baseline, similarly to younger patients. Postoperative outcome scores and MCID achievement demonstrated differences between groups at intermittent timepoints. With appropriate selection criteria, patient age may not act as a notable risk factor for successful MIS TLIF procedures.Practicing orthopaedic surgeons are subject to both the requirement and the opportunity to participate in individual or group quality assessment, quality-based payment programs, and clinical data registries. An important limitation to participating in and receiving the benefits of quality measuring activities and programs is the lack of a current resource outlining quality assessment models, current quality metrics, and the presence and function of current quality programs, payment models, and active orthopaedic registries. This article is intended as a primer for the practicing orthopaedic surgeon and orthopaedic groups. We provide a detailed overview of current quality metric databases, their categorization and use, and orthopaedic surgeon's role in creating and shaping the definition of quality care and outcomes assessment in the future. Physical function evaluated by Patient-Reported Outcomes Measurement Information System (PROMIS PF) instrument has been validated through the short-term postsurgical period in spine surgery patients. Evidence for long-term efficacy of PROMIS PF is lacking in lumbar decompression (LD) patients. The objective of this study was to evaluate correlations between PROMIS PF and legacy patient-reported outcome measures for patients undergoing LD. Consecutive primary or revision, single-level or multilevel LD surgeries were retrospectively reviewed from May 2015 to September 2017. Patients lacking preoperative or 2-year PROMIS PF scores were excluded. D
