Background: Excessive cartilage degradation is a known characteristic of osteoarthritis (OA). Biochemical markers, such as uCTX-II, have been shown to be associated with disease severity, yet the tissue origin of CTX-II has been disputed. This analysis investigates the association between OA knee joints at different radiographic stages and pain categories with levels of uCTX-II and biomarkers of bone resorption and formation.
Methods: Baseline data of two randomised clinical trials (NCT00486434 and NCT00704847) in patients with radiographic OA and presence of pain were analysed post hoc. A subgroup with available urine samples and evaluable radiographs for both knees (N = 1241) was analysed. Urine CTX-I, urine CTX-II and serum osteocalcin were analysed for associations with combined Kellgren-Lawrence (KL) scores, gender and pain for both knees to assess the contribution of joints at different stages.
Results: Pain, BMI, age, gender and KL grade were all significantly associated with uCTX-II. The association between pain and CTX-II appeared to be driven by weight-bearing pain. The level of uCTX-II incrementally increased with higher radiographic severity of each knee. Levels of bone markers CTX-I and osteocalcin were both significantly associated with BMI and gender, but neither were associated with radiographic severity. Biomarker levels between male or female groups of identical KL scores were found to be higher in females compared to males in some but not all KL score groups.
Conclusions: These results indicate that levels of uCTX-II are independently associated with radiographic severity of OA and pain intensity. CTX-II was associated with weight-bearing pain, but not non-weight-bearing pain, independent of co-variates. Bilateral OA knee joints appear to contribute to uCTX-II levels in an incremental manner according to radiographic severity of single joints. The data suggest that biomarker differences between genders should be taken into account when evaluating these markers in the context of structural features of OA.

Objectives: To compare the value of musculoskeletal ultrasound (MSUS) with conventional radiography in the detection of patients with early rheumatoid arthritis (RA) and to correlate the sonographic findings with disease activity, and functional disability scores.
Methods: Patients >18 years of age with RA ≤2 years who satisfied the 2010 EULAR/ACR classification criteria for rheumatoid arthritis and disease activity score 28 (DAS28) >2.6, were enrolled.

Objective: To maximize local tumor control, stabilize affected bones, and preserve or replace joints with minimal interventional burden, thereby enhancing quality of life for empowered living.
Indications: Suitable for patients with bone metastases, particularly those with severe pain and/or fractures and appropriate life expectancy.
Contraindications: In primary bone tumors, refer to the sarcoma surgery team for evaluation of wide resection.

Background: Although total hip and total knee arthroplasty are highly successful operations, the decision of whether and when to undergo surgery is highly subjective and discretionary, and specific guidelines regarding readiness for surgery remain elusive. The nature of these decisions underscores the importance of shared decision-making, which is founded on the concept that patients substantially contribute to determining their own readiness for surgery. The OPTION survey was developed as a conversation aid to facilitate shared decision-making in the context of total joint arthroplasty.

Background: Prune belly syndrome (PBS) is a rare condition characterized by absence of abdominal musculature, cryptorchidism, and obstructive uropathy. The most common orthopaedic problem is scoliosis, yet no reports on growth-friendly surgical treatment of early-onset scoliosis (EOS) exist. Our purpose was to evaluate outcomes of distraction-based implants in children with PBS.

Purpose: The aim of this study was to evaluate the effectiveness of single-photon emission computed tomography/computed tomography (SPECT/CT) in detecting and localizing the causative vertebra in cases of suspected fresh osteoporotic vertebral compression fractures (OVCFs) in patients with contraindications to MRI.
Methods: A total of 21 patients with severe back pain with 31 suspected OVCF segments and contraindications to MRI were initially identified through radiographs and the back pain-inducing test (BPIT). The responsible vertebral bodies were determined using [Tc]MDP SPECT/CT before percutaneous vertebroplasty (PVP).
