BACKGROUND AND OBJECTIVES: Radiofrequency ablation of genicular nerves has proved to be successful in relieving pain and incapacity caused by osteoarthritis of the knee. However, long-term efficacy of such a treatment remains to be assessed. The current study aimed to reproduce radiofrequency neurotomy of genicular nerves to manage gonarthrosis pain and disability and establish therapeutic response until 1 year after intervention. METHODS: This single-center, prospective, observational, noncontrolled, longitudinal study included patients with grade 3 to 4 gonarthrosis suffering from intractable knee pain, scoring 5 or more on the visual analog scale (VAS) during >6 months...

BACKGROUND: Musculoskeletal disorders (MSD) are the leading cause of sickness absence (SA) in Spain and the second in Catalonia. A greater knowledge of this field could allow the refocusing of social protection policies and interventions to reduce their frequency and duration. The objective of the study was to describe the characteristics and duration of SA due to MSD in Catalonia between 2007 and 2010. METHODS: The study population included all incident SA episodes due to MSD during the period 2007-2010, registered in the Institut Català d'AvaluacionsMèdiques (ICAM) database...

Gonarthrosis is a degenerative disease that affects mainly older people, but whose incidence has increased significantly in the last decade in population under the age of 65. The main objective of this study was developing a predictive model of synovial membrane degradation in relation to local nerve structures in patients with knee osteoarthritis, based on advanced morphometry and artificial neural networks (ANNs). We present here a pilot test of the method, describing preliminary findings in analyzing a pre-set number of images...

Lactococcus garvieae is known as a Gram-positive, catalase-negative, and facultatively anaerobic fish pathogen. The association between Lactococcus spp. and human infectious diseases is described as being mainly associated with lumbar osteomyelitis, hepatic abscess, and infective endocarditis. In the literature of orthopedic post-prosthetic infections, L. garvieae was associated with a case of hip prosthetic infection in a fishmonger woman. We present the case of a 79-year-old male patient with multiple comorbidities, who is admitted to our center with a 5-day history of pain, swelling, and motility disorder of the right knee by the presence of a bicondylar knee replacement surgery, which was performed due to gonarthrosis 17 years ago...

Chronic lateral dislocation of the patella is a rare condition and acquired causes are usually secondary to knee trauma. The neglected chronic dislocation leads to progressive genu valgum and external tibial torsion deformities with subsequent gonarthrosis, which becomes painful and debilitating. There is no consensus regarding treatment of these patients, but total knee arthroplasty (TKA) is a useful therapy in cases of painful symptomatic gonarthrosis. Few reports have shown that subvastus approach and lateral release may be a valid option for TKA, since it allows the correction of valgus deformity and patellar tracking without interrupting vascular blood supply of patella...

BACKGROUND AND OBJECTIVES: Total knee arthroplasty and total hip arthroplasty are associated with chronic pain development. Of the studies focusing on perioperative factors for chronic pain, few have focused on the differences that might arise from the anesthesia type performed during surgery. METHODS: This was a prospective observational study performed between July 2014 and March 2015 with patients undergoing unilateral elective total knee arthroplasty (TKA) or total hip arthroplasty (THA) for osteoarthritis...

Varus knee malalignment caused by medial compartment arthritis results in progressive asymmetric wear of the tibiofemoral joint. This wear can cause progressively painful gonarthrosis. Surgical methods to address varus knee malalignment include lateral closing-wedge proximal tibial osteotomy, medial opening-wedge osteotomy, and arthroplasty. Medial opening-wedge proximal tibial osteotomy is an effective procedure for restoring proper coronal alignment and reducing knee pain. In this technical note, we present a reproducible technique for proximal tibial osteotomy...

OBJECTIVE: The aim was to analyze the gait of knee osteoarthritis patients before osteotomy. MATERIAL/PATIENTS AND METHODS: Twenty-four patients aged 52.4 years±6.8, 15M/9F, were comparatively analyzed to 24 matched controls. Deficiencies and disabilities were evaluated by means of: numeric pain scale, Lysholm, Koos and Womac and SF-36 scores. They were also asked to estimate their self-perception of gait on a 4-level scale. Spatiotemporal gait parameters were also measured at comfortable speed, using an optical system (otpogait)...

BACKGROUND: For patients with knee osteoarthritis, even slight anatomical variations in the femur or the tibia could affect total limb alignment during total knee replacement (TKR). Our hypothesis implies that the femoral valgus correction angle (VCA) in patients indicated for TKR, is variable and higher than the reported norm of 6° utilized in most intramedullary instrumentation systems, and that tibial bowing may result to a disparity of the tibial mechanical axis to the anatomical axis...

BACKGROUND: Non-steroidal anti-inflammatory drugs (NSAIDs) are frequently prescribed to relieve pain and inflammation. These NSAIDs have also analgesic effects and can be administered via oral, injectable, and topical routes. During inflammation, a number of synovial mediators and cytokines are released which decrease the pH level of the synovial fluid. Administration of acidic NSAIDs further decreases the pH levels and hence contributes to the destruction of the cartilage. To our knowledge, no cellular-based study regarding the chondrotoxicity of phenyl alkanoic acid derivatives on NSAIDs was conducted before...

REVIEW
Benjamin V Herman, J Robert Giffin
High tibial osteotomy (HTO) has traditionally been used to treat varus gonarthrosis in younger, active patients. Varus malalignment increases the risk of progression of medial compartment osteoarthritis and an HTO can be performed to realign the mechanical axis of the lower limb towards the lateral compartment, thereby decreasing contact pressures in the medial compartment. Anterior cruciate ligament (ACL) insufficiency may lead to post-traumatic arthritis due to altered joint loading and associated injuries to the menisci and articular cartilage...

PURPOSE: Impaired proprioception accuracy of the knee has been proposed as a local factor in the onset and progression of knee osteoarthritis. Patients with decreased numbers of mechanoreceptors could be more likely to develop arthrosis due to a loss in proprioception of the joint. We aimed to identify and quantify the mechanoreceptors of the posterior cruciate ligament (PCL), the anterior capsule (AC) and the medial meniscocapsular junction (MCJ) in knee arthrosis. METHODS: PCLs, ACs and MCJs were harvested from 30 patients with Kellgren and Lawrence grades 3 and 4 osteoarthritis (OA), and ten knees taken from five cadavers without OA were used as a control group...

Analysis of polymorphisms of genes encoding antioxidant enzymes SOD1 (G7958A), SOD2 (T58C), CAT (C-262T), and GSTP1 (Ile105Val) in 93 patients with post-traumatic gonarthrosis showed that GSTP1 Ile105Val polymorphism is often associated with heterozygous mutation in catalase gene CAT C-262T. In gonarthrosis, catalase activity in peripheral blood mononuclear cells in patients with CT genotype of the C-262T locus of CAT gene more than 2-fold surpassed that in CC genotype and more than 50% surpassed the normal...
