BACKGROUND: Gait modifications can reduce the knee adduction moment, a representation of knee loading. Reduced loading may help to slow progression of medial knee osteoarthritis. We aimed to investigate the response of patients with medial knee osteoarthritis to direct feedback on the knee adduction moment as a method for modifying the gait pattern, before and after training with specific gait modifications. METHODS: Forty patients with medial knee osteoarthritis underwent 3D gait analysis on an instrumented-treadmill, while receiving real-time feedback on the peak knee adduction moment...

Anti-citrullinated protein antibodies (ACPAs) are a key serological marker of rheumatoid arthritis (RA). To investigate whether miR-let7a downregulated ACPA-induced macrophage activation and arthritis, miR-let7a levels were assessed in the synovial fluid from patients with RA or osteoarthritis (OA). In addition, expression of the pro-inflammatory genes HMGA2, PI3K, and IRF5 was examined in ACPA-induced macrophages and a collagen antibody-induced mouse model of arthritis. As expected, miR-let7a expression in synovial fluid macrophages was substantially lower in patients with RA than in those with OA...

BACKGROUND: Several recent reports define the line from the centre of the femoral head to the lowest point of the calcaneus. The purpose of this study was to comparatively examine the usefulness of the hip-calcaneus (HC) line and hip-ankle (HA) line for the evaluation of lower-limb alignment in healthy individuals and in patients with osteoarthritis (OA). METHODS: Participants included 34 healthy individuals (mean age, 26.4years) and 34 patients with OA (mean age, 74...

BACKGROUND: Injury is an important risk factor for osteoarthritis (OA), a highly prevalent and disabling joint disease. Joint shape is linked to OA, but the interplay of injury and joint shape and their combined role in OA, particularly at the ankle, is not well known. Therefore, we explored cross-sectional associations between ankle shape and injury in a large community-based cohort. METHODS: Ankles without radiographic OA were selected from the current data collection of the Johnston County OA Project...

Articular tuberculosis of the ankle joint is a rare presentation of skeletal tuberculosis (10% of cases). This unusual location and the low index of clinical suspicion leads to delays in diagnosis and treatment. Radiographic and analytic studies are unspecific in the first stage. CAT and MRI are useful in diagnosis. Chemotherapy is the mainstay of treatment and surgery is often required to establish the diagnosis and in the treatment. We report a case of ankle tuberculosis in a 22 month-old child. The diagnosis was confirmed by synovial biopsy...

Lower limb strengthening exercise is pivotal for the management of symptoms related to knee osteoarthritis (OA). Though improvement in clinical symptoms is well documented, concurrent changes in gait biomechanics are ill-defined. This may occur because discrete analyses miss changes following an intervention, analyses limited to the knee undermine potential mechanical trade-offs at other joints, or strengthening interventions not been designed based on biomechanical principles. The purpose of this study was to characterize differences in entire gait waveforms for sagittal plane ankle, knee, and hip angles and external moments; the knee adduction moment; and frontal plane hip angle and moment following 12-weeks of a previously designed novel lower limb strengthening program...

PURPOSE: Arthroscopic bone marrow stimulation (BMS) has been considered the primary surgical treatment for osteochondral defects (OCDs) of the talus. However, fixation has been considered as a good alternative. Recently, a new arthroscopic fixation technique was described: the lift, drill, fill and fix procedure (LDFF). The purpose of this study was to evaluate the clinical and radiological results between arthroscopic LDFF and arthroscopic BMS in primary fixable talar OCDs at 1-year follow-up...

BACKGROUND: Capsular shrinkage is an arthroscopic stabilization technique that can be used in patients with chronic ankle instability (CAI), if desired in addition to primary arthroscopic procedures. Despite positive short-term results, long-term follow-up of these patients has not yet been performed. Therefore, our objective was to assess whether capsular shrinkage still provided functional outcome after 12-14 years compared to preoperative scores. METHODS: This study was a retrospective long-term follow-up of a prospectively conducted longitudinal multicenter trial...

Structural abnormalities on MRI are frequent after an ankle sprain. To determine the association between patient history, physical examination and early osteoarthritis (OA) in patients after a previous ankle sprain, 98 patients with persistent complaints were selected from a cross-sectional study. Patient history taking and physical examination were applied and MRI was taken. Univariate and multivariable analyses were used to test possible associations. Signs of OA (cartilage loss, osteophytes and bone marrow edema) were seen in the talocrural joint (TCJ) in 40% and the talonavicular joint (TNJ) in 49%...

RATIONALE: High tibial osteotomy (HTO) has been used widely for medial compartment knee osteoarthritis to correct the deformity and relieve symptoms, especially in young patients who are willing to maintain the high activity level. However, the change of bone morphology, ligament imbalance, limb malalignment, and other complications may influence the short-term outcomes of HTO. Some cases may even require conversion to TKA shortly after HTO because of the loss of correction or pain due to accelerated osteoarthritis...

BACKGROUND: Ankle fractures are frequently occurring injuries. Despite the relatively simple operative technique, patients often suffer from postoperative complications. Little is known about postoperative treatment of implant-associated infections of the ankle. Therefore, this study shows and evaluates a treatment algorithm in long- and short-term outcomes compared to infection-free patients. METHODS: Data from patients of over 20 years of a level 1 trauma center and university hospital was retrospectively analyzed including age, gender, comorbidities, smoking status, fracture classification, number of revisions, length of in-patient stay due to fracture and infection, and results of microbiological specimen with the length of antibiotic treatment...

INTRODUCTION: There are few specific reports of late medial instability after total knee arthroplasty (TKA). We described two cases of late medial instability of the knee due to hip disease with osteoarthritis or rheumatoid arthritis after TKA, which required revision TKA. PRESENTATION OF CASES: An 82-year-old woman experienced right femoral neck fracture due to a fall that required conservative treatment at age 77 years and underwent left TKA at age 80 years. A 68-year-old woman underwent left TKA at age 54 years, right TKA at age 64 years, and left THA at age 67 years...

Background Talar osteochondral lesions are an important risk factor for the development of talar osteoarthritis. Furthermore, osteochondral lesions might explain persistent ankle pain. Early diagnosis of accompanying chondral defects is important to establish the optimal therapy strategy and thereby delaying or preventing the onset of osteoarthritis. The purpose of this review is to explain modern cartilage imaging with emphasis of MR imaging as well as the discussion of more sophisticated imaging studies like CT-arthrography or functional MR imaging...

A subset of C2/C3 pilon fractures, open pilon injuries, metaphyseal bone comminution, and those involving substantial soft tissue or vascular injury may be nonreconstructable. Such injuries are at risk of progress to nonunion and failing open reduction internal fixation (ORIF). The risk of infection, malunion, and nonunion is relatively high with such injury patterns. In such cases, tibiotalar arthrodesis is performed after ORIF fails as a salvage procedure. Overall, the literature agrees that all pilon fractures will develop posttraumatic osteoarthritis, and these patients are ultimately treated with an arthrodesis or in narrow population with total ankle arthroplasty...
