The influence of previous joint arthroplasty on fulfillment of patients' expectations of subsequent lumbar surgery.
The objective of this study was to analyze the association of previous arthroplasty with patients' postlumbar surgery fulfillment of expectations. The findings indicated that patients had less fulfillment of expectations with subsequent lumbar surgery. The authors concluded that surgeons should discuss potential differences between arthroplasty and lumbar surgery during preoperative evaluations and postoperative assessments.

How back pain affects patient satisfaction after primary total knee arthroplasty.
This study looked at patient-reported outcomes (PROs) for patients with back pain (BP) who underwent total knee arthroscopy (TKA) surgery for pre- and postoperatively. This multicenter cohort study included 9,057 patients undergoing primary unilateral TKA who were enrolled in FORCE-TJ. Back pain (BP) intensity was assessed using the Oswestry back disability index (ODI) pain intensity questionnaire, with BP severity then classified into 4 categories. PROs were collected preoperatively and postoperatively after 1 year including the Knee injury and Osteoarthritis Outcome Score (KOOS) (total score, pain, Activities of Daily Living (ADL), and Quality of Life (QOL), Short-Form health survey 36-item (SF-36) Physical Component Score (PCS), and Mental Component Score (MCS)). At 1 year a total of 18.3% TKA patients were dissatisfied. At the time of surgery, a total of 4,765 patients (52.6%) reported back pain, divided into mild BP (24.9%), moderate (20.3%), and severe (7.2%). Severe back pain was significantly associated with patient dissatisfaction at 1 year after TKA. The predictive variables for dissatisfaction include age [odds ratio (OR) for younger patients <65 years versus older patients ≥65 years], educational level [OR for post high school versus less], smoking [OR for nonsmoker versus current smoker)], and Charlson comorbidity index [OR for CCI ≥2 versus 0]. The authors recommend surgeons consider a spine evaluation in patients who have severe BP prior to TKA.
