A 68-year-old man with right knee varus osteoarthritis was treated by lateral closed-wedge high tibial osteotomy. A correction loss with non-union occurred 6 months after surgery and a re-correction osteotomy was performed. Removing the proximal screws of the lateral plate, a medial opening-wedge re-osteotomy was performed. Arthroscopically harvested osteophytes were used to fill the gap after opening. An additional medial locking plate was installed on the medial side. Finally, the proximal lateral screws were reinserted and locked again...

OBJECTIVES: Meniscal pathology is integral to knee osteoarthritis (OA) and its progression; it provides a progression biomarker and a potential treatment target. MRI demonstrates large heterogeneity in meniscal damage; this structural complexity means measurement is difficult. The aim of this study was to apply novel 3D image analysis to determine which meniscal pathologies demonstrated most change during OA progression. METHODS: Knee images were selected from the progression cohort of the Osteoarthritis Initiative choosing participants with risk factors for medial OA progression...

Pediatric ankle fractures are common and have unique fracture characteristics because of the presence of distal tibial and fibular physes. When displaced (>3 mm widening of the physis or >2 mm intra-articular gap/step-off), these fractures are typically treated with anatomical reduction and internal fixation. Computed tomography is recommended for preoperative evaluation and surgical planning for intra-articular fractures. These fractures in younger children with substantial growth remaining should be followed closely to monitor for any growth disturbance...

BACKGROUND: Spontaneous osteonecrosis of the knee (SONK) is a clinical entity identified by acute knee pain usually associated with joint effusion, with radiographic findings of a radiolucent defect on the weightbearing area of the femoral condyle. Conservative treatment is initially undertaken; however, surgical procedures are often necessary. Historically, surgical options have included core decompression, cartilage repair, high tibial osteotomy, or joint arthroplasty. Few studies in the literature have reported the use of fresh osteochondral allograft (OCA) for the treatment of SONK lesions...

BACKGROUND: Patient-specific instrumentation (PSI) is attracting attention as a mechanical method of ensuring the accuracy of osteotomy during total knee arthroplasty (TKA). Few studies have focused on preoperative plans; thus, it is unclear how often initial plans have to be corrected preoperatively and intraoperatively. We investigated the frequency of corrections, the accuracy of intraoperative osteotomy, and postoperative alignment. METHODS: We analyzed 45 knees of 40 patients who underwent TKA using magnetic resonance imaging (MRI)-based PSI...

Developing effective treatment for osteoarthritis (OA), a prevalent and disabling disease, has remained a challenge, primarily due to limited understanding of its pathogenesis and late diagnosis. In the subchondral bone, rapid bone loss following traumatic injuries and bone sclerosis at the advanced stage of OA are well-recognized hallmarks of the disease. Recent studies have further demonstrated the crucial contribution of subchondral bone in the development of OA. However, the microstructural basis of these bone changes has not been examined thoroughly, and the paradox of how abnormal resorption can eventually lead to bone sclerosis remains unanswered...

REVIEW
J Mthethwa, A Chikate
Tibial plateau fractures form a wide spectrum of injuries presenting varying challenges to the trauma surgeon. The prognosis of this injury spectrum is largely dependent on the management of each particular configuration, and the literature is as a result littered with a number of management strategies with limited consensus. The aim of this review is to provide a concise guide to the trauma surgeon based on newer and classical peer-reviewed publications in international orthopaedic journals. A PubMed search was conducted to identify peer-reviewed publications within the last 10 years and expanded to identify classic papers pertaining to the Schatzker classification...

Post-menopausal osteoporosis (PMO) is a major global human health concern. Owing to the need for therapeutic drugs without side effects, natural extracts containing various polyphenolic compounds that may exert estrogenic effects have been studied in depth. Rhus verniciflua Stokes (RVS), which has been used as a traditional herbal medicine for centuries in Korea, was recently revealed to exert estrogenic effects attributable to its bioactive ingredients sulfuretin and butein, which have strong estrogen receptor-binding affinities...
