“…One recent prospective study by Mortensen et al performed a direct comparison between the Rosenberg and valgus stress radiograph in assessment of the lateral JSW in 73 patients prior to PKR or TKR [ 18 ]. Our results are in line with their findings; they demonstrated a 0.45–0.62 mm smaller lateral JSW on valgus stress compared to Rosenberg radiographs with a similar precision and strong correlation between the JSW measured on the Rosenberg and the valgus stress radiograph.…”

“…Studies that directly compare the Rosenberg and valgus stress radiographs are scarce. Moreover, the difference found in JSW measured between the Rosenberg and valgus stress radiographs are very small (< 1 mm) [ 18 ]. Yet, the added value of valgus stress radiographs in patients with (suspected) medial knee osteoarthritis remains unclear and would be valuable to assess.…”

Introduction A valgus stress radiograph, in addition to the weight-bearing fixed flexion posteroanterior radiograph (e.g., Rosenberg), is deemed useful to assess lateral cartilage wear by measuring lateral joint space width (JSW) in patients with medial knee osteoarthritis. This study aimed to assess: (1) the difference in measured lateral JSW between the Rosenberg and the valgus stress radiograph, and (2) the ability of the valgus stress radiograph to detect lateral cartilage wear (indicated by joint space narrowing) in patients where the Rosenberg radiograph showed full thickness cartilage (i.e., the additional value). Materials and methods The Rosenberg and valgus stress radiographs, obtained between January 1st 2018 and December 31st 2018, of 137 patients with medial knee osteoarthritis prior to total or partial knee replacement were retrospectively collected. The lateral JSW was measured at its midpoint (midJSW) and minimum (minJSW). The differences were tested with a paired-sample t test. The valgus stress radiograph was considered to have an additional value if: (1) JSW ≥ 5 mm on the Rosenberg radiograph, (2) JSW < 5 mm on valgus stress radiograph, and (3) > 2 mm less JSW on the valgus stress than on the Rosenberg radiograph. Results The mean differences in lateral JSW between the Rosenberg and valgus stress radiographs were 0.53 mm (SD = 1.0 mm, p < 0.001) for midJSW and 0.66 mm (SD = 1.1 mm, p < 0.001) for minJSW with both values being lower on the valgus stress radiograph. The valgus stress radiograph was of additional value in 4–6% of the patients. Conclusions Although the valgus stress radiograph shows more lateral JSW narrowing compared to Rosenberg radiograph, it only has an additional value in 1 out of 17–25 patients with medial osteoarthritis. We, therefore, recommend a Rosenberg radiograph as routine radiographic assessment and only use an additional valgus stress radiograph in case of discrepancy between clinical and radiological findings.

PurposeThe aim of this study was to identify preoperative predictors for 1‐year posttotal knee arthroplasty (TKA) pain and pre‐ to post‐TKA pain difference in knee osteoarthritis (KOA) patients.MethodsFrom March 2018 to July 2023, this prospective longitudinal cohort study enrolled KOA patients awaiting TKA from four hospitals in Belgium and the Netherlands. Different biopsychosocial predictors were assessed preoperatively by questionnaires and physical examinations (input variables). The Knee injury and Osteoarthritis Outcome Score (KOOS) subscale pain was used to measure pain intensity. The absolute KOOS subscale pain score 1‐year post‐TKA and the difference score (ΔKOOS = 1‐year postoperative − preoperative) were used as primary outcome measures (output variables). Two multivariable linear regression analyses were performed.ResultsTwo hundred and twenty‐three participants were included after multiple imputation. Worse absolute KOOS subscale pain scores 1‐year post‐TKA and negative or closer to zero ΔKOOS subscale pain scores were predicted by self‐reported central sensitisation, lower KOA grade and preoperative satisfaction, and higher glycated haemoglobin, number of pain locations and personal control (adjusted R2 = 0.25). Additional predictors of negative or closer to zero ΔKOOS subscale pain scores were being self‐employed, higher preoperative pain and function (adjusted R2 = 0.37).ConclusionThis study reports different biopsychosocial predictors for both outcomes that have filtered out other potential predictors and provide value for future studies on developing risk assessment tools for the prediction of chronic TKA pain.Protocol RegistrationThe protocol is registered at clinicaltrials.gov (NCT05380648) on 13 May 2022.Level of EvidenceLevel II.
