    ABSTRACT: Cross-sectional studies have shown that patients with primary hip osteoarthritis (OA) have higher bone mineral density (BMD), higher BMI, lower lean body mass, and higher fat content. But it is unknown if this phenotype is found also in patients with knee OA and if it precedes OA or manifests as a result of the disease. We included 21 women and 18 men (mean age, 71 years; range, 48-85 years) with primary OA in all three knee compartments, 17 women and 56 men (mean age, 55 years; range, 34-74 years) with primary medial knee OA and 122 women and 121 men without OA as controls. We measured total body BMD (g/cm(2)), fat and lean mass (%) by dual energy X-ray absorptiometry and also registered height and weight to calculate BMI (kg/m(2)). Z-scores were calculated for each individual. Data are presented as means with 95% confidence intervals within brackets. Individuals with primary OA in all three knee compartments had the following Z-scores: total body BMD 0.4 (0.0, 0.9); BMI 1.2 (0.7, 1.6); proportion of lean mass -0.6 (-1.1, -0.1); proportion of fat mass 0.4 (0.0, 1.8). Individuals with medial knee OA had the following Z-scores: total body BMD 0.4 (0.3, 0.6); BMI 1.1 (0.8, 1.4); proportion of lean mass -0.8 (-1.3, -0.9); proportion of fat mass 0.9 (0.7, 1.1). A phenotype with higher BMD, higher BMI, higher fat mass, and proportionally lower lean body mass is evident in individuals with primary OA in all three knee compartments and in patients with only medial knee OA.

    ABSTRACT: The aim of our study was to analyze the clinical outcome after repair of cartilage defects of the knee with subchondral drilling and resorbable polymer-based implants immersed with autologous platelet-rich plasma (PRP). Fifty-two patients with focal chondral defects were treated with subchondral drilling, followed by covering with a polyglycolic acid - hyaluronan (PGA-HA) implant (chondrotissue®) immersed with autologous PRP. At 5-year follow-up, patients' situation was assessed using the Knee Injury and Osteoarthritis Outcome Score (KOOS) and compared to the pre-operative situation. The KOOS showed clinically meaningful and significant (p < 0.05) improvement in all subcategories compared to baseline. Subgroup analysis showed that there were no differences in the clinical outcome regarding defect size and localization as well as degenerative condition of the knee. Cartilage repair was complete in 20 out of 21 patients at 4-year follow-up as shown by magnetic resonance observation of cartilage repair tissue (MOCART) scoring. Covering of focal cartilage defects with the PGA-HA implant and PRP after bone marrow stimulation leads to a lasting improvement of the patients' situation.

    ABSTRACT: CT scanning is an important tool in the evaluation of trauma patients. We review a case involving a trauma patient in which a cervical spine computed tomography (CT) artifact affected decision-making by physicians. The CT artifact mimicked bilateral dislocated facets (51-B1.1). On the basis of CT findings, the patient was transferred to a different hospital for evaluation. Discrepancy between the primary CT scan and patient physical exam prompted secondary CT scans and X-ray evaluation; neither of these studies showed osseous abnormalities. This case reinforces the necessity for physicians to formulate their diagnosis based upon multiple areas of information including physical examination, plain x-ray and subsequent advanced imaging, rather than relying solely on advanced imaging.

    ABSTRACT: We introduce a new set of modifications and present the results from 48 patients (a total of 60 feet operated), who underwent this modified Wilson's osteotomy for the correction of Hallux Valgus. Patients were of an average age of 52 years old (from 21 to 75 years of age) and were followed up for a mean of 12 months post-operatively. Patient evaluation was made with the symptom scoring system as presented by Kataraglis et al., with the final outcome being satisfactory in all of the cases. This set of modifications introduced to the original Wilson's osteotomy, proved to offer a stable, predictable and satisfactory outcome in all cases and we strongly recommend it.

    ABSTRACT: In the case of primary malignant tumors, extensive metastatic disease, major trauma or end-stage revision arthroplasty, the orthopaedic surgeon often has to deal with the need to reconstruct large skeletal defects, or replace bone of low quality. In the past years this was frequently impossible, and the only solution was amputation of the extremity. Later, the introduction of custom-made endoprostheses capable of reconstructing large skeletal defects, also known as megaprostheses, allowed for sparing of the extremity. This was especially valuable in the case of oncologic orthopaedic surgery, as advances in the medical treatment of sarcoma patients improved prognosis and limb-preserving surgery proved to have comparable patient survival rates to amputation. However, custom-made designs were implicated in frequent mechanical failures. Furthermore, they were extremely difficult to revise. The introduction of modular endoprostheses in the 1980s marked a new era in orthopaedic oncologic surgery. Modular megaprostheses consist of a number of different components in readily available sets, which can be assembled in various combinations to best address the specific bone defect. Moreover, they proved to have considerably lower rate of mechanical failures, which were also much easier to address during revision surgery by replacing only the parts that failed. The functional outcome after reconstruction with megasprostheses is often very satisfactory and the patient can enjoy a good quality of life. Nowadays, the major challenge is to eliminate the rate of non-mechanical complications associated with surgery of that magnitude, namely the risk for wound dehiscence and necrosis, deep infection, as well as local recurrence of the tumor. In our present mini-review, we attempt to make a critical approach of the available literature, focusing on the multiple aspects of reconstructive surgery using megaprostheses. We present the evolution of megasprosthetic implants, the indications for their use, and describe the outcome of surgery, so that the non-specialized orthopedic surgeon also becomes familiar with that kind of surgery which is usually performed in tertiary centers. A special interest lays in the recent developments that promise for even better results and fewer complications.

    ABSTRACT: The use of conventional modalities for chronic neck pain remains debatable, primarily because most treatments have had limited success. We conducted a review of the literature published up to December 2013 on the diagnostic and treatment modalities of disorders related to chronic neck pain and concluded that, despite providing temporary relief of symptoms, these treatments do not address the specific problems of healing and are not likely to offer long-term cures. The objectives of this narrative review are to provide an overview of chronic neck pain as it relates to cervical instability, to describe the anatomical features of the cervical spine and the impact of capsular ligament laxity, to discuss the disorders causing chronic neck pain and their current treatments, and lastly, to present prolotherapy as a viable treatment option that heals injured ligaments, restores stability to the spine, and resolves chronic neck pain. The capsular ligaments are the main stabilizing structures of the facet joints in the cervical spine and have been implicated as a major source of chronic neck pain. Chronic neck pain often reflects a state of instability in the cervical spine and is a symptom common to a number of conditions described herein, including disc herniation, cervical spondylosis, whiplash injury and whiplash associated disorder, postconcussion syndrome, vertebrobasilar insufficiency, and Barré-Liéou syndrome. When the capsular ligaments are injured, they become elongated and exhibit laxity, which causes excessive movement of the cervical vertebrae. In the upper cervical spine (C0-C2), this can cause a number of other symptoms including, but not limited to, nerve irritation and vertebrobasilar insufficiency with associated vertigo, tinnitus, dizziness, facial pain, arm pain, and migraine headaches. In the lower cervical spine (C3-C7), this can cause muscle spasms, crepitation, and/or paresthesia in addition to chronic neck pain. In either case, the presence of excessive motion between two adjacent cervical vertebrae and these associated symptoms is described as cervical instability. Therefore, we propose that in many cases of chronic neck pain, the cause may be underlying joint instability due to capsular ligament laxity. Currently, curative treatment options for this type of cervical instability are inconclusive and inadequate. Based on clinical studies and experience with patients who have visited our chronic pain clinic with complaints of chronic neck pain, we contend that prolotherapy offers a potentially curative treatment option for chronic neck pain related to capsular ligament laxity and underlying cervical instability.
