Palmaris longus muscle, although of little functional use to the human upper limb, assumes great importance when used as a donor tendon for transfer or transplant. The variability in the prevalence of palmaris longus agenesis among various ethnic groups has been established, and the surgeon's awareness of the prevalence in a population or ethnic group is desirable. The prevalence of palmaris longus agenesis has, to the best of the authors' knowledge, not been reported in Indian patients. Five hundred Indian patients were examined for the presence or absence of palmaris longus tendon, using the conventional test for presence of palmaris longus. The prevalence and pattern of palmaris longus agenesis was analyzed statistically and any difference in prevalence or pattern of palmaris longus agenesis with regard to body side or sex was looked for. All statistical analysis was done using SPSS (version 12). chi2 test was used to analyze the association of agenesis with limb laterality and sex. The prevalence of palmaris longus agenesis was found to be 17.2% (8% bilateral and 9.2% unilateral). The prevalence of agenesis was significantly more common on the left side. Male subjects had a greater likelihood of unilateral agenesis, while female subjects were more likely to have bilateral agenesis. That prevalence of palmaris longus agenesis is race dependent is reaffirmed in the present study. Although the prevalence of palmaris longus agenesis in Indian patients was found to be much higher than the reported average prevalence in an Asian population, this tendon can still be counted on by surgeons treating Indian patients for use as a donor tendon, which will be present in a vast majority of Indian patients.

Background: Osteoarthritis (OA) is one of the major cause of morbidity, having a substantial influence on health quality of life, imposing enormous burden of cost on the health care system. It is a chronic degenerative disorder that is characterised by articular cartilage degeneration. It can be caused by aging, heredity and injury from trauma or disease. Primary symptoms of OA include joint pain, stiffness and limitation of movement. Disease progression is usually slow but can ultimately lead to joint failure with pain and disability. Stromal vascular fraction (SVF) derived from adipose tissue is a rich source of pre adipocytes, mesenchymal cells (MSC), endothelial progenitor cell, T cells, B cells, mast cells as well as adipose tissue macrophages. It can be easily obtained from loose connective tissue that is associated with adipose tissue by lipoaspiration under local anaesthesia. SVF is isolated without using any enzymes or chemicals and its autologous grafting is done in a single surgical sitting. Here, we evaluated safety and clinical efficacy of freshly isolated Autologous SVF cells in patients with grade 2-4 degenerative osteoarthritis (OA). . Methods: A total of 116 joints mainly knee OA were treated with autologous grafting of SVF done in a single surgical sitting. A total of 116 joints studied out of which 80 joints were followed up for 12 months, 88 joints followed for 9 months, 110 joints followed for 6 months and finally all 116 joints were followed for minimum 1 month for safety and efficacy. Results: Modified KOOS clinical score was used to evaluate clinical effect and was based on pain, non-steroid analgesic usage, limping, extent of joint movement, and stiffness evaluation before and at pre-operative, 1 Month post-op, 6 months post-op and 12 Months post-op after grafting. No side effects, systemic infection or cancer was associated with Autologous grafting of SVF. There was a significant improvement from pre-op to post op in all the followed patients. Average KOOS score improved from pre-operative 46.4 to post-operative 12 months average 77.9 i.e. very significant improvement in all grades. All sub-scale parameter for pain, symptoms, activity of living and quality of life showed significant improvement. Higher grade of OA were associated with comparatively slower healing. Conclusions: Autologous grafting of SVF in single surgical sitting is a novel and promising treatment approach for patients with degenerative OA. This treatment method was found to be minimal invasive, safe and cost-effective treatment modality for osteoarthritis.

<p class="abstract"><strong>Background:</strong> Distal femur is a complex fractures and most of times a personalized approach is needed for these fractures. Over a period of time variety of approaches and implants have been used for these fractures. The use of retrograde femur nail for fixing femur fracture, using entry from inter-condylar notch of femur, is a known method of treatment, but most surgeons are apprehensive of making an entry from the knee joint because of possible complications like knee pain, arthro-fibrosis, infections etc .The aim of this study was to investigate its effectiveness in fixation of distal 1/3^rdfracture of femur with special emphasis on the outcome and inherent surgical challenges<span lang="EN-IN">.</span></p><p class="abstract"><strong>Methods:</strong> A prospective study of 40 patients with fracture femur diaphysial distal one third were treated by retrograde nailing, from July 2010 to January 2016, after obtaining required approval from the Institutional ethical &amp; research committee. All the patients were followed till fracture union and evaluated on the basis of demography, duration of healing, complications and surgical challenges.<strong></strong></p><p class="abstract"><strong>Results:</strong> We observed that mean age of patients was 35.8 years (18 years to 62 years) where 87.5% were male and 12.5% were female.

Mean knee range of motion was 124.5 degree (70 to 140 degree), rate of knee pain 10% (4/40), re-operation rate 5% (2/40), infection rate 2.5% (1/40), and fat embolism 2.5% (1/40)<span lang="EN-IN">. </span></p><p class="abstract"><strong>Conclusions:</strong> Retrograde femoral nailing is a reliable alternative to antegrade nailing or plate fixation for diaphyseal fracture distal one third femur, and may be in some situations even advantageous when antegrade nail entry is challenging like ipsilateral hip fractures, previous implant in hip &amp; proximal femur, ipsilateral pelvi-acetabular injury, bilateral femoral shaft fracture, floating Knee injuries, poly-trauma and obese patients<span lang="EN-IN">.</span></p>

<p class="abstract"><strong>Background:</strong> Femoral component rotation in total knee arthroplasty (TKA) is essential for patella-femoral tracking, flexion gap balance and normal kinematic function of the knee. The two referencing techniques used for sizing and adjudging the femoral rotation are anterior referencing (AR) and posterior referencing (PR).The current study was designed so as to identify which referencing system determines the femoral rotation more accurately<span lang="EN-IN">.</span></p><p class="abstract"><strong>Methods:</strong> This study involved 34 consecutive patients (22 females and 12 males) with 60 osteoarthritic knees (bilateral=26; unilateral =8) who satisfied the inclusion criteria. The trans-epicondylar axis, was taken as gold standard to adjudge the correct femoral rotation and was marked as E. The axis of rotation as per anterior instrumentation (A), and as per posterior instrumentation (P) were marked and compared as to which of the axis (A or P) was parallel to E.<strong></strong></p><p class="abstract"><strong>Results:</strong> A was always parallel to E, however P was parallel to E in 42 knees.
