INTRODUCTION: Femoral neck fractures are a common occurrence in lower limb amputees. Good post-operative results of hip hemiarthroplasty have been described in below-knee amputees. However, to our knowledge, very few such cases have been reported in above-knee amputees. CASE REPORT: We present a case of a 75-year-old male patient who underwent above-knee amputation of the right lower limb for severe crush injury right leg and a bipolar hemiarthroplasty for an ipsilateral fracture neck of femur sustained in the same road traffic accident...

REVIEW
Mohammad Shahid, Rik Kundra
Platelet-rich plasma (PRP) is an autologous blood product with platelet concentrations above baseline values. The process involves the extraction of blood from the patient which is then centrifuged to obtain a concentrated suspension of platelets by plasmapheresis. It then undergoes a two-stage centrifugation process to separate the solid and liquid components of the anticoagulated blood. PRP owes its therapeutic use to the growth factors released by the platelets which are claimed to possess multiple regenerative properties...

Eugene Kim, Giovanni Cucchiaro
Spinal cord stimulation can be a valuable treatment option in the management of neuropathic pain in select pediatric patients. We present a unique case of a 16-year-old girl with Klippel-Trenaunay-Weber syndrome and scoliosis who required the placement of a spinal cord stimulator (SCS) for severe sciatic nerve neuropathic pain after a right above-knee amputation. Several attempts at lead placement were required before successful pain coverage was achieved because of late recognition of significant vertebral body rotation...

BACKGROUND: Training intensity is an important variable in strength training and above 80% of one repetition maximum is recommended for promoting strength for athletes. Four dynamic and two isometric on-field exercises are included in the Hölmich groin-injury prevention study that initially failed to show a reduction in groin injuries in soccer players. It has been speculated that exercise-intensity in this groin-injury prevention program was too low to induce the strength gains necessary to protect against groin-related injuries...

BACKGROUND: Hemophilic pseudotumor (HPT) is a rare disease with many challenges. Only a few reports on surgical treatment for HPT have been published. METHODS: The cases of 23 patients with HPT who had surgical treatment from July 1996 to December 2014 were retrospectively reviewed. Demographic data, blood loss and transfusion during surgery, outcomes, and complications after surgery were analyzed. RESULTS: Eleven patients underwent HPT resection; 4 underwent HPT excision, allograft transplantation, and absorbable screw fixation; 3 had HPT resection and metallic internal fixation; 2 had HPT resection, autogenous fibular grafting, and absorbable screw fixation; 2 underwent curettage and bone-grafting; and 1 patient received above-the-knee amputation...

BACKGROUND: Knee osteoarthritis (OA) is a leading joint disease. In most of the early stages it does not involve the whole knee joint. Often, symptoms only or mainly concern the medial compartment combined with a slight varus malalignment. OBJECTIVES: Do valgus braces or laterally wedged insoles influence biomechanics and thus improve pain and function in patients with medial OA? Does the OA grade, severity of malalignment or patient's body weight predict the efficacy of the above-mentioned conservative treatment options? MATERIALS AND METHODS: The current literature was reviewed in regard to biomechanical changes to joint loading and their correlation to clinical results...

A gear-based knee joint is designed to improve the performance of mechanical-type above-knee prostheses. The gear set with the help of some bracing, and bracket arrangement, is used to enable the prosthesis to follow the residual limb movement. The motion analysis and finite-element analysis (FEA) of knee joint components are carried out to assess the feasibility of the design. The maximum stress of 29.74 MPa and maximum strain of 2.393e-004 are obtained in the gear, whereas the maximum displacement of 7...

PURPOSE: Autologous subchondral bone grafting in combination with autologous chondrocyte implantation (ACI) (sandwich procedure) is a well-accepted procedure for the treatment of osteochondral lesions of the knee. This requires a different surgical technique and preoperative planning compared to ACI alone. In addition, pain from bone marrow donor site locations can be expected and should be part of patient consent and expectations. This study evaluates whether the MRI made as part of the standard preoperative cartilage patient work up has the diagnostic accuracy to predict the need for a sandwich procedure...

Extraintestinal infections due to Clostridium difficile are uncommon. When such infections occur, extraintestinal C. difficile isolates are usually identical to fecal isolates. We present a rare case of a large postoperative abscess caused by C. difficile infection, in which different C. difficile strains were isolated from the abscess and from feces of the patient. An 82-year-old woman with cutaneous polyarteritis nodosa developed pain, skin ulcers, and extensive necrosis of the right leg. Above-knee amputation was performed without stopping antiplatelet therapy, leading to postoperative hematoma...

BACKGROUND: Malalignment of the lower extremity is commonly seen in patients with severe osteoarthritis undergoing total knee arthroplasty (TKA) and is believed to play a role in quadriceps strength loss. Deformity correction is typically achieved through surgical techniques to provide appropriate ligamentous balancing. Therefore, this study examined the influence of change in lower extremity alignment on quadriceps strength outcomes after TKA. METHODS: Seventy-three participants (36 male; mean age, 62 years; and mean body mass index, 29...

R Sehjal, N Bakti, R Goddard
BACKGROUND: Effective operating room ventilation is required to reduce the risk of surgical site infection. Vertical laminar airflow from above the surgical field provides a source of 'ultra-clean' air, carrying contaminants away from the operative site. An anaesthetic screening drape is often used to shield the operative site from the anaesthetic team, and this defies the principles of vertical laminar airflow. METHODS: A mock theatre set-up for a total knee replacement was constructed with and without the use of an anaesthetic screening drape...

With antiretroviral therapy, patients who are human immunodeficiency virus (HIV)-positive are increasingly becoming candidates for total hip arthroplasty (THA) and total knee arthroplasty (TKA). Prior reports focus on perioperative complications, but longer-term outcomes remain unclear. The authors specifically analyzed clinical outcomes, perioperative complications, and survivorship free of periprosthetic joint infection (PJI) of THAs and TKAs in HIV-positive patients who had extended follow-up. A total of 21 HIV-positive patients who underwent 29 primary arthroplasties (14 THAs, 15 TKAs) from 1992 to 2012 were retrospectively reviewed...

INTRODUCTION: Previous studies show a limited alteration of gait at normal walking speed after spinal fusion surgery for adolescent idiopathic scoliosis (AIS), despite the presumed essential role of spinal mobility during gait. This study analyses how spinal fusion affects gait at more challenging walking speeds. More specifically, we investigated whether thoracic-pelvic rotations are reduced to a larger extent at higher gait speeds and whether compensatory mechanisms above and below the stiffened spine are present...

The popliteal fossa is the site of several diseases that may be similar in the clinical setting but very different in aetiology, treatment and prognosis. The contemporary presentation of more than one of these conditions is a rare though potentially fatal combination that may lead to a delay in the diagnosis and therapeutic approach. In this report we describe the case of a patient that presented at our Vascular Department for persistent pain and severe swelling of the right popliteal fossa eight months after the surgical treatment of a symptomatic popliteal aneurysm by mean of a dacron prosthetic graft...
