BACKGROUND: Lower extremity analysis for preoperative total knee and hip arthroplasty routines can increase surgery success rate and hence reduce associated costs. Current tools are limited by being invasive, limited to supine analysis, or too expensive. This study aimed to propose and validate a device, OrthoPilot®, based on the combined use of a stereophotogrammetric and ultrasound system which can in vivo and noninvasively measure varus/valgus, flexion/extension, femur and tibia torsion, and femur and tibia lengths...

OBJECTIVE: Navigated computer-assisted total knee arthroplasty (TKA) shows inconclusive mid- to long-term outcome results and is limited by increased costs, surgery-time and an additional learning curve. We introduced a treatment algorithm preserving computer-assisted TKA for patients with adipositas-per-magna, posttraumatic leg-deformities, osteosynthetic material in-situ or reduced preoperative X-ray quality. METHODS: 237 primary unilateral TKA were allocated based on the treatment concept described above...

A 60-year-old man, who had claudication in his right limb due to total occlusion of the right superficial femoral artery, received bare metal stents. Although the bare metal stents in the superficial femoral artery did not show restenosis 5 years after stent implantation, angiography revealed significant in-stent restenosis when he developed right critical limb ischemia at 8 years post implantation. Ballooning for in-stent lesions did not result in full expansion. His right limb was amputated above the knee due to progressive limb ischemia...

BACKGROUND: Knee osteoarthritis (KOA) is a common chronic degenerative disorder. It causes joints pain, walking difficulties and a decline of general physical function. Many pain drugs and treatment modalities can be prescribed for KOA. Among traditional medicine in Morocco, Argan oil has been used in the treatment of knee osteoarthritis to reduce pain and improve physical activity, though there have been no medical-based evidence for such treatment. Argan oil is known to have anti-oxidant and lipid modulatory properties due to its content of many substances, such as tocopherols, phytosterols, saturated and unsaturated fatty acids...

BACKGROUND: Adductor canal block (ACB) and local infiltration anesthesia (LIA) are both widely accepted techniques for postoperative pain control without quadriceps weakness after total knee arthroplasty (TKA). However, the above techniques are insufficient in efficacy or duration. AIMS: The aim of our study was to address whether ACB plus posterior capsular infiltration (PCI) result in improved analgesia compared with ACB or LIA in patients underwent TKA during 48 h after operation...

PURPOSE: Distal femoral periprosthetic fractures above a total knee replacement in elderly patients are technically challenging to treat. Bone quality is often poor, the fractures comminuted, and post-operative mobilisation is difficult. This study assesses the clinical, radiological and functional outcome of revision knee distal femoral replacement (DFR) in these fractures. METHODS: We identified 14 patients over 70 years of age (70-94) who underwent DFR for periprosthetic fractures above a knee replacement...

We report a successful management of a case of methicillin-resistant Staphylococcus aureus positive right lower limb cellulitis for above knee amputation under combined nerve blocks. The ongoing sepsis, thrombocytopenia, and severe respiratory infection with wheeze made us avoid both neuraxial block and general anesthesia and plan for a nerve block. We instituted a modified high inguinal femoral block along with sciatic and lateral femoral nerve blocks separately to successfully conduct the case. We decided to report as there were not as many cases as ours in the literature...

AIMS: Periprosthetic fracture is a significant complication of total hip and knee arthroplasty. This study aimed to describe the survival of patients sustaining periprosthetic femoral fractures and compare this with that of the general population, as well as to identify the factors that influence survival. PATIENTS AND METHODS: A total of 151 patients (women: men 116:35, mean age 74.6 years, standard deviation 11.5) that sustained a periprosthetic fracture between January 2005 and October 2012 were retrospectively analysed...

AIMS: We aimed to investigate factors related to the technique of medial opening wedge high tibial osteotomy which might predispose to the development of a lateral hinge fracture. PATIENTS AND METHODS: A total of 71 patients with 82 osteotomies were included in the study. Their mean age was 62.9 years (37 to 80). The classification of the type of osteotomy was based on whether it extended beyond the fibular head. The level of the osteotomy was classified according to the height of its endpoint...

PURPOSE: As the aims of changes in total knee arthroplasty (TKA) designs are to reinstate more natural kinematics, the current study evaluated the in vivo kinematics in patients who underwent a cruciate retaining gradually changing femoral radius ("G-CURVE") against a cruciate retaining conventional changing femoral radius ("J-CURVE") geometry TKA design. The hypothesis of the study is that the G-CURVE design would allow a substantial increase in the femoral rollback compared to the J-CURVE design...

BACKGROUND: Injury to the infrapatellar branch of the saphenous nerve (IPBSN) is a high-frequency complication in anterior cruciate ligament (ACL) reconstruction. We analyzed the risk factor of IPBSN injury in ACL reconstruction. Moreover, we investigated the influence on treatment outcome by this complication. METHODS: One hundred twenty-three patients who underwent ACL reconstruction using semitendinosus tendon graft were studied. Gender, age, BMI, and additional use of gracilis tendon were recorded...

BACKGROUND: Lateral soft-tissue release can jeopardize the common peroneal nerve (CPN) in total knee arthroplasty for valgus knees. Previous studies reporting safe zones to protect the CPN were based on well-aligned knees. We conducted this study to compare the localization of the CPN in well-aligned knees and in valgus knees. METHODS: We conducted a consecutive 3-dimensional radiographic study on magnetic resonance images of 58 well-aligned knees and 39 valgus knees...

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...
