Radiographic Evaluation of Medial Opening-Wedge High Tibial Osteotomy Using a New Internal Fixator with a Wedge-Shaped Spacer Block

J Knee Surg DOI: 10.1055/s-0039-1700977We developed a new internal fixator: a rigid T-shaped plate with locking screws and wedge-shaped spacer block for high tibial osteotomy. The purpose of the present study was to evaluate the radiographic outcome of opening-wedge high tibial osteotomy (OWHTO) using this new internal fixator. Sixty OWHTOs were performed in patients with medial compartment osteoarthritis and varus deformity (28 males and 23 females). Patients' mean age was 60.4 years. Preoperative and postoperative radiographs were obtained. The paired t-test was used to evaluate the differences over time with respect to radiographic variables. Union of the osteotomy gap was obtained in all patients, and no implant breakage was found. On anterior–posterior radiographs, a significant difference was observed (p

This study aimed to identify clinical phenotypes based on clinical prognostic factors in patients with secondary hip OA using data from prospective cohort studies and to define the clinical features of each phenotype.MethodsFifty patients participated. Two-step cluster analysis was performed to identify the phenotypes using the following potential prognostic factors for hip OA progression: spinal inclination in standing, thoracolumbar spine mobility, daily cumulative hip moment, and minimum joint space width (JSW) at baseline. Comprehensive basic and clinical features (age, body mass index, hip pain, Harris hip score, JSW,...

ConclusionAlthough rare, osteoid osteoma may occur in the hallux. Even if the patient age, pain pattern, and radiographic findings do not exactly meet the classical definitions for osteoid osteoma, this tumor should always be included in the differential diagnosis list in patients presenting with foot pain.

We describe, in this article, the hinged joint distraction technique. A total of 50 patients with posttraumatic ankle osteoarthritis with a mean age of 40.0±8.5 years were included in a prospective randomized study: 25 patients in ankle debridement alone group and 25 patients in debridement and hinged ankle distraction group. The mean follow-up was 46±12 months (range: 36 to 78 mo). The clinical and radiographic outcomes were evaluated at the 6-month and 3-year follow-up using the Visual Analog Scale (VAS), American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot score, SF-36 quality of life score,...

CONCLUSION:  RSO can be a good alternative in the treatment of synovitis and prevention of deterioration of inflammatory and radiographic features even in patients suffering from osteoarthritis and rheumatoid arthritis. RSO may have also a long-term effect to stop or delay progression of both diseases. PMID: 32074661 [PubMed - as supplied by publisher]

AbstractPurposeTo perform a radiographic assessment of osteoarthritis, progression after partial meniscectomy (PM) in degenerative medial meniscus posterior root tears (MMPRTs) in relation to preoperative mechanical axis (MA). The hypothesis is that neutral-aligned knees with degenerative MMPRTs have better radiographic outcomes than those of varus-aligned knees after arthroscopic PM.MethodsRecords of 114 patients with degenerative MMPRTs and Kellgren –Lawrence (KL) grade ≤ 2 osteoarthritis, who underwent PM, had preoperative weight-bearing hip-to-ankle radiographs from 2004 to 2014, and were followed-up fo...

This study aimed to provide an update on the association between MetS and OA and on the potential role of leptin in OA. In this review, we summarized the current knowledge of the association between MetS and OA and updated the evidence on the potential role of leptin in OA. Clinical studies have investigated the epidemiologic association between MetS or its components and OA. Results suggested strong epidemiologic associations between MetS and OA, especially in the Asian population. Animal studies also indicated that metabolic dysregulation may lead to OA pathogenesis. The systemic role of MetS in OA pathophysiology is ass...

CONCLUSION: Overall, having or developing DM and/or CVD reduced the likelihood of symptomatic and functional improvement over time, suggesting an impact of comorbid CVD and DM on the clinical and radiographic course of HOA. Additional studies are needed to confirm these findings. PMID: 32062598 [PubMed - as supplied by publisher]
