How to enhance tendon graft incorporation into bone tunnels for achieving satisfactory healing outcomes in patients with anterior cruciate ligament reconstruction (ACLR) is one of the most challenging clinical problems in orthopaedic sports medicine. Several studies have recently reported the beneficial effects of Mg implants in bone fracture healing, indicating the use potential of Mg devices in promoting the tendon graft osteointegration. Here, we developed an innovative Mg-based interference screws for fixation of the tendon graft in rabbits underwent ACLR and investigated the biological role of Mg-based implants in the graft healing...

BACKGROUND: Guidelines for patient blood management recommend restrictive transfusion practice for most adult patients. These guidelines are supported by evidence from randomised controlled trials (RCTs); however, one of the patient groups not explicitly examined in these studies is the geriatric population. We examined RCTs relevant to transfusion outcomes in older patients. Our aim was to determine whether special guidelines are warranted for geriatric patients, recognising the different pathophysiological characteristics of this group...

PURPOSE: The purpose of this study was to describe patterns of pain during the first year following total knee arthroplasty (TKA) and evaluate pre- and postoperative factors associated with pain and patient satisfaction at 1 year. It was hypothesized that more severe preoperative pain would be associated with more residual pain and lower patient satisfaction 1 year after surgery. METHODS: A longitudinal cohort study was performed with repeated measures of pain (0-10 numeric rating scale) and evaluation of other self-reported symptoms (Hospital Anxiety and Depression Scale, Pittsburgh Sleep Quality Index, and Fatigue Severity Score), daily functioning (Lawton Instrumental Activities of Daily Living Scale), quality of life (EQ-5D-3L), knee function (KSS Knee and Function Score), perioperative and clinical characteristics (e...

Background Symptomatic pre-arthritic deformities such as femoroacetabular impingement (FAI) or hip dysplasia often lead to localised cartilage defects and subsequently to osteoarthritis. The present review of the working group "Clinical Tissue Regeneration" of the German Society of Orthopaedics and Trauma (DGOU) and the hip committee of the AGA (German speaking Society for Arthroscopy and Joint Surgery) provides an overview of current knowledge of the diagnosis and surgical treatment of cartilage defects, in order to infer appropriate therapy recommendations for the hip...

BACKGROUND: Patients who sustain orthopaedic trauma in the form of fractures commonly ask treating providers whether the bone is "fractured" or "broken". While orthopaedic surgeons consider these terms synonymous, patients appear to comprehend the terms as having different meanings. Given the commonality of this frequently posed question, it may be important for providers to assess patients' level of understanding in order to provide optimal care. The purpose of this study is to evaluate patients' comprehension and understanding regarding the use of the terms fractured and broken...

BACKGROUND: Many patients with X-linked hypophosphataemic rickets (X-LHPR) demonstrate significant lower limb deformity despite optimal medical management. This study evaluates the use of guided growth by means of hemi-epiphysiodesis to address coronal plane deformity in the skeletally immature child. METHODS: Since 2005, 24 patients with X-LHPR have been referred to our orthopaedic unit for evaluation. All patients had standardised long leg radiographs that were analysed sequentially before and after surgery if any was performed...

PURPOSE: Mucopolysaccharidoses (MPS) are a group of rare lysosomal storage disorders associated with involvement of multiple organs along with a generalised skeletal dysplasia. Both haematopoetic stem cell transplant and enzyme replacement therapy have improved the outlook for patients while surgery remains high-risk and there is little information on clinical or functional outcome to justify many of the surgical procedures performed. This paper aims to summarise the orthopaedic surgical procedures in MPS patients for which quality of life (QoL) and functional data are available and to describe additional QoL and functional measurement tools of relevance to the assessment of orthopaedic outcomes in MPS...

BACKGROUND: The treatment of symptomatic partial rotator cuff tear has presented substantial challenge to orthopaedic surgeons as it can vary from conservative to surgical repair. Researches have established the influence of platelet rich plasma in healing damaged tissue. Currently very few data are available regarding the evidence of clinical and radiological outcome of partial rotator cuff tear treated with ultrasound guided platelet rich plasma injection in English literature. MATERIALS AND METHODS: 20 patients with symptomatic partial rotator cuff tears were treated with ultrasound guided platelet rich plasma injection...

INTRODUCTION: Major lower limb amputation significantly increases the energy cost of walking for patients. Complications such as osteomyelitis may require further surgery, and can lead to shortening of the stump. In these cases, the aim should be to treat infection without shortening the limb further. We present a series of patients with established osteomyelitis of the amputation stump, managed using a modified Lautenbach technique. METHOD: Six patients with either above or below knee amputations, in the practice of a single orthopaedic surgeon, were studied...

OBJECTIVE: It is difficult to completely and safely remove a tumor that is located in the subaxial cervical spine by using the posterior approach because of the anatomical characteristics. Previous reports regarding the total removal of subaxial schwannomas using the one-stage posterior approach are still limited. This study was to evaluate the feasibility and efficacy of treating the dumbbell-shaped schwannomas in the subaxial cervical spine using the one-stage posterior approach. METHODS: Patients with dumbbell-shaped schwannomas in the subaxial cervical spine were treated using the one-stage posterior approach...

BACKGROUND: There is still no evidence in literature for damage control orthopaedics (DCO), early total care (ETC) or using external fixation solely in fractures of the long bones in multi-system-trauma. The aim of this study was to determine parameters influencing the choice of treatment in clinical routine (DCO, ETC, or EF) in femoral or tibial shaft fractures in combination with multi-system-trauma, severe soft tissue damage or both. METHODS: Data of 236 patients with 280 fractures of long bones of the lower extremities treated at a level I trauma center were analysed...

BACKGROUND: Heel pain with or without calcaneal spur is a challenging problem. Once conservative measures have failed, surgery may be indicated; there has been debate about the best surgical procedure. Two standard operative procedures have been either releasing the plantar fascia or removing the spur with drilling of the calcaneus. In this study, we evaluated the results of percutaneous drilling of the calcaneus combined with mid-sole release of the plantar fascia for treatment of resistant heel pain...

Kristin Oliver, Tariq Awan, Matthew Bayes
BACKGROUND: Bone marrow concentrate (BMC) is growing in popularity as an alternative treatment option in orthopaedics. The regenerative capacity of BMC has been linked to the number of mesenchymal stem cells (MSCs) present in the graft at the time of its clinical application. MSC counts in bone marrow aspirate (BMA) are affected by harvest technique, but controversy exists over which aspiration method optimizes cellular yield while taking patient comfort and risk into consideration. PURPOSE: To compare a single- versus multiple-site bone marrow aspiration technique to determine which would generate a sufficient volume of high-quality BMA for concentration into a BMC graft...

OBJECTIVE: The American Academy of Orthopaedic Surgeons (AAOS) recently published appropriateness criteria for patients with knee osteoarthritis (OA) who are being considered for total knee arthroplasty (TKA). We evaluated the extent to which predictor variables used by the AAOS contribute to final classification, rated as "appropriate," "may be appropriate" or "rarely appropriate." METHODS: The RAND/UCLA Appropriateness method was used by AAOS to develop 864 clinical vignettes, each incorporating eight evidence-based variables associated with TKA outcome or need...

The mechanisms of metal release from the articulation at the head cup bearing and the tapered junctions of orthopaedic hip implants are known to differ and the debris generated varies in size, shape and volume. Significantly less metal is lost from the taper junction between Cobalt-Chromium-Molybdenum (CoCrMo) and Titanium (Ti) components (fretting-corrosion dominant mechanism), when compared to the CoCrMo bearing surfaces (wear-corrosion dominant mechanism). Corrosion particles from the taper junction can lead to Adverse Reactions to Metal Debris (ARMD) similar to those seen with CoCrMo bearings...
