Many of the methods used to assess knee mechanics after total knee arthroplasty (TKA) have failed to create realistic testing conditions in terms of joint load and range of motion. In contrast, motion capture studies facilitate knee assessments during functional, weight-bearing activities. Using motion capture techniques, this study aimed to examine differences in sagittal tendon kinematics between TKA and normative individuals. The relative positions of the patellar tendon and quadriceps tendon, as a function of knee flexion-extension, were estimated during step down and bilateral deep knee bend tasks. To assess the validity of this technique, motion capture data were compared to radiographic data for each TKA patient. Sagittal knee tendon angles were measured directly from the radiographs and compared to corresponding points in the dynamic data. Results of the patellar and quadriceps tendon angles showed good agreement between the two methods, with absolute errors ranging from 2.9o to 5.6o, suggesting that noninvasive motion capture is a suitable method for evaluating knee mechanics.","PeriodicalId":322846,"journal":{"name":"The Internet Journal of Orthopedic Surgery","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122927338","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Peter","doi":"10.5580/164e","DOIUrl":"https://doi.org/10.5580/164e","url":null,"abstract":"Introduction Orthopaedic surgery consumes a considerable proportion of blood available to the National Health Service. Effective and judicious management of available blood is therefore vital. In order to review the usage of packed red cells in our centre, we carried out an audit involving patients who underwent total hip and knee replacement.Methods A retrospective audit was carried out to include all patients who underwent elective total hip and knee replacement, and underwent blood transfusion. A total of 449 patients were included and those who underwent transfusion were identified.Results Sixty five patients (14.5%) underwent blood transfusion. Approximately 5% required blood transfusion in both primary and revision TKR. 16% transfused in uncemented primary THR. 27.3% transfused in cemented primary THR. 30.7% transfused in uncemented revision THR. 77.7% transfused in cemented revision THR. 133 units were transfused in total out the 198 requested.Conclusion The present audit demonstrates that the cross matched to transfused ratio is within 2:1. Efforts should be made to reduce it to 1:1 where transfusion is necessary. This will aid in not only reducing the cost of transfusion, but also in reducing the risks associated with blood transfusion. INTRODUCTION Hip and knee joint replacements are very common and very successful orthopaedic procedures and the numbers done are increasing year on year. This is partly to do with the fact that it is being done in much younger age groups than before and due to the increase in the aging population. It is estimated that by 2033, 23% of the population will be aged 65 and above. Orthopaedic surgery consumes a considerable proportion of blood available to the National Health Service. It has been reported to be in the range of 10 – 15%. The increasing demand will further burden the National Blood service. Blood transfusion is accompanied by potentially fatal hazards. Although the risk of infection contracted through blood transfusion is declining, the non infectious serious hazards of transfusion will contribute to the morbidity and mortality associated with transfusion. It is also predicted that this might remain as a leading cause in the coming years. Effective and judicious management of available blood is therefore vital and should become part of joint replacement surgery. In order to review the usage of packed red cells in our centre, we carried out an audit involving patients undergoing elective total hip (THR) and total knee (TKR) joint replacement. The aim of the audit was to assess the extent of red cells being used and to compare it to other studies and also to serve as a baseline for future audits in our department. METHODS A retrospective audit was carried over a 6 month period between February 2008 and July 2008. A full list of patients who underwent elective THR and TKR was obtained.

Motten, Nipun Kalsotra, Manjeet Singh, Nidhi Mahajan, U. Kiran","doi":"10.5580/2207","DOIUrl":"https://doi.org/10.5580/2207","url":null,"abstract":"This is a prospective study of the role of closed interlocking nailing of fractures of the shaft of the tibia in 25 cases aged from 18-54 years, out of which 23 (92%) were males and 2 (8%) were females. Th right side was involved in 13 (52%) patients and the left in 12 patients (48%). Motor vehicle accidents were the major cause of the tibial fractures (80%). There were 18 (72%) closed and 7 (28%) open fractures and most of the fractures were either oblique (36%) or transverse (32%) while 20% were comminuted, spiral 8% and 4% were segmental. Reamed closed interlocking nailing was done in most cases under image intensifier. Partial weight bearing was started within the first two weeks in 84% of patients after surgery and full weight bearing was started at 6 weeks. Fracture united in 100% of cases in our series and time of union ranged from 11-28 weeks with the average 14 weeks in 24 cases. Excellent results were found in 18 (72%) cases. In 4 (16%) cases results were good and in two cases results were fair. In one (4%) case result were poor, who had delayed union and deep infection. INTRODUCTION The tibia is the most commonly fractured long bone. The optimal method of treatment for these injuries remains debatable. In spite of all the advances, fractures of the tibia still pose a challenge to the orthopaedic surgeons and thus the management of the fractured tibia requires the widest experience, the greatest wisdom, and the nicest of the clinical judgement in order to choose the most appropriate treatment for particular pattern of injury. That is why Sir John Charnley long back spoke rightly that “we have still a long way to go before the best method of treatment of fractures of the shaft of the tibia can be stated with finality”. Since the advent of intramedullary fixation it has undergone several modifications specially the advent of locking which has widened the rather limited indications of unlocked nailing. When operative fixation is indicated locked I.M. nail at present appears to be an attractive surgical option, as it is the only operative modality closest to the safe yet rewarding and time honoured conservative treatment. The intramedullary interlocking nail can be solid or hollow type and can be used either in static or dynamic mode, may be reamed or undreamed, but however the ideal technique remains a matter of controversy. Presented here is a clinical study for evaluation of results of closed interlocking nailing of fractures of the shaft of the tibia in 25 cases done in the post graduate department of orthopaedics, GMC, Jammu.
