ABSTRACT OBJECTIVES Anterior knee pain is a common problem in patients who have undergone TKR which causes dissatisfaction among them. There are Various methods for prevention of anterior knee pain following TKR .The objective of this study is to determine the effect of circumpatellar electrocautery on anterior knee pain following TKR and to compare the results with that of those patients who have undergone TKR without circumpatellar denervation. METHODS This is a cohort study conducted in Dept. of Orthopedics, Govt. Medical College, Kozhikode,kerala, 2014. Total sample size was 90.out of which 2 patients died during the study period. We lost follow up of 7 patients. Among the remaining 81 patients 42 had undergone TKR with circumpatellar denervation using electocautery and 39 without circumpatellar denervation. They were kept under follow up. Patients were followed up postoperatively at 1 month, 3 months, 6 months and at one year. At all postoperative visits, a clinical score was determined using the Knee Society score and the clinical anterior knee pain rating system described by Waters and Bentley RESULTS There is no statistically significant difference in AKP score between both groups.There is a statistically significant difference in the knee society score at 1 st month(p value <.001). But there is no difference on further follow up visits . CONCLUSION There is no statistically significant difference between final outcome of patients who underwent patella denervation using circumpatellar electrocauterisation and those without denervation with respect to anterior knee pain among patients who have undergone TKR.

Our health care system has faced many challenges over the past 40 plus years. Now these challenges have forced us into a complicated situation that makes it confusing on how best to proceed. Today third party insurance payers make most health care payments. Our premiums are paid into a risk pool-on medical services for other people. Consumers are disconnected from knowing the cost of goods or services that they are receiving. This commentary reviews the current situation and provides a few common sense approaches for pursuing the best potential policies.

Modular neck femoral components were introduced to optimize femoral neck anteversion, leg length, offset, and stability in total hip arthroplasty. However, concerns have been raised in recent years regarding early failure of these implants due to corrosion, pseudotumor, as well as fracture of the modular neck. Removing modular neck femoral implants is challenging as removal of the modular femoral neck leaves a proximally coated femoral stem level with the proximal bone of the femoral neck. We describe a posterior femoral single limb osteotomy (posterior cut of an extended trochanteric osteotomy) for the removal of a modular neck femoral component.

In the setting of periprosthetic joint infection, the complete removal of implants and cement can be challenging with well-fixed, cemented implants about the knee. This can get especially complex in the setting of long cemented femoral component stems. Osteotomies are well described in the proximal femur and tibia for removal of implants and cement. There is little information available on distal femoral osteotomies. We describe an anterolateral oblique distal femoral osteotomy for the removal of well-fixed, cemented components in resection knee arthroplasty that preserves vascularity to the osteotomized segment.

Partial knee (unicompartmental) arthroplasty (PKA) for medial compartment disease of the knee has a long and well documented history of successful results over long periods of follow up. The Oxford Partial Knee Replacement has been available in the U.S. since 2004. After completing an FDA required instructional course, surgeons may use the device. Both the implant and the instruments have evolved since its introduction in 2004. This paper outlines the authors continuous cohort of 249 patients, 286 knees from 2004 to 2014 with minimum 2 year follow up, and reports the results while discussing the impact of experience, instruments and implants, and technique on the outcome of patients in this series. For the aggregate group of 286 knees, there were 17(5.9%) all-cause revisions to TKA, including 2(0.7%) dislocations, resulting in a (83%) survivorship at ten years. The survivorship at ten years for retained implants was 97% if non-implant related causes are not included. At one year, there were 89% excellent and good results, 5% fair, and 6% poor. At two years, there were 93% excellent and good, 1 % fair, and 5.5% poor. The causes for the poor results at one and two years were tibial sided failure or persistent pain. Three (12%) of patients with a poor result at one year had converted to good and excellent at two years. The use of the Oxford Mobile Bearing™ PKA has been shown to be a useful part of the surgeon’s surgical armamentarium when dealing with anteromedial osteoarthritis or osteonecrosis of the knee. PKA has been shown to have a lower morbidity and mortality and is cost effective when compared to total knee arthroplasty. The author’s experience, as demonstrated in this study, adds validity to the concept that understanding the pathoanatomy of anteromedial osteoarthritis and gaining surgical experience through increased surgical volume, adherence to well documented technique, and the use of a time proven implant, can be accomplished with a high degree of successful outcomes for patients with the appropriate indications.

The length of time to return to work after Total Knee Replacement is often treated as a monolithic entity. Figures produced under such an assumption are interesting but have little practical value in individual cases. Numerous factors most of which are not under medical control are involved. What is clear however is that the timing of surgery is of considerable importance in a job specific situation and this is under medical control.

Background: The medial tibial reduction osteotomy (MTRO) was introduced to achieve coronal ligamentous balance in total knee arthroplasty (TKA) patients with substantial preoperative varus deformity. Limited data exists on the outcomes of patients requiring an MTRO. This study compares outcomes of a matched cohort of patients that either required or did not require an MTRO during TKA. Methods: A retrospective review was performed on 67 patients that underwent an MTRO during primary TKA to achieve coronal balance. This patient population was matched 1:1 to another cohort of TKA patients by age, gender, and BMI that did not require an MTRO. A clinical and radiographic evaluation was utilized to compare the two cohorts. Results: Preoperatively, the tibiofemoral angle was 3.42° valgus versus 6.12° varus in the control and MTRO cohorts respectively (p=0.01). Mean postoperative tibiofemoral angles were 3.40° versus 2.43° valgus respectively. Postoperative Knee Society Scores were superior in the MTRO cohort (183.84 versus 174.58; p=0.04). Intraoperatively, no superficial MCL releases were required to achieve coronal balance in either cohort. Complications were similar and limited in both groups. Medial tibial bone resorption was observed in 64% of MTRO subjects averaging 2.02mm versus only 0.3mm in the control cohort ( p=0.01). Conclusion: Patients requiring an MTRO achieved similar alignment and superior knee scores compared to a control cohort with less varus deformity. This procedure eliminated the need for release of the superficial MCL. Resorption of medial tibial bone was commonly observed, possibly secondary to saw-induced thermal necrosis associated with performing an MTRO.

Abstract Introduction: Short stems have been designed with the purpose of preserving bone tissue, decreasing the incidence of thigh pain and facilitating surgical techniques. The aim of our study was to assess whether a shortened tapered conventional stem was able to reduce the incidence of thigh pain. Methods: Between March 2010 and December 2012, 200 patients were enrolled in the study. Visual analogue scale (VAS) that included mapping of the pain, Harris Hip Score (HHS), Short Form-12 (SF-12) and radiographic outcomes were evaluated prior to surgery as well as at 6, 12 and 24 months post-operatively. Results: After 6 months, 6 patients (3%) had thigh pain. After 12 months, 3 patients (1.5%) complained about thigh pain. After 2 years, 2 patients (1%) had thigh pain. There was no correlation between pain and clinical, radiological, or demographic variables. Conclusion: The shortened tapered conventional stem resulted in a lower incidence of thigh pain for up to 2-years following surgery, compared with conventional or other short stems.

The following office tip describes four patients that underwent primary total knee arthroplasty and developed posterolateral knee pain at a mean follow-up duration of 1.6 months postoperatively. The first patient in this series noted substantial pain lying in bed (in a lateral decubitus position with the operative leg up) while attempting to abduct her leg to adjust her sheet in bed. A thorough clinical and radiographic work-up was performed. This patient’s posturing in bed (and subsequent physical exam maneuver) led to a presumptive diagnosis of popliteal tendinopathy. The diagnosis was confirmed arthroscopically by identifying a frayed and inflamed popliteal tendon. After undergoing arthroscopic popliteal tendon release, the patient noted complete pain relief while retaining coronal stability in both flexion and extension. The following office tip defines a previously undescribed clinical diagnostic examination for popliteal tendinopathy that was identified based on a patient’s symptomatology and subsequently utilized to identify three additional cases of arthroscopically confirmed popliteal tendinopathy.

Background Achieving correct leg and femoral neck lengths remains a challenge during total hip arthroplasty (THA). Several methods for intraoperative evaluation and restoration of leg length have been proposed, and each has inaccuracies and shortcomings. Both the supine positioning of a patient on the operating table during the direct anterior approach (DAA) THA and the preservation of the anterior capsule tissue are simple, readily available, and cost-effective strategies that can lend themselves well as potential solutions to this problem. Technique The joint replacement is performed through a longitudinal incision (capsulotomy) of the anterior hip joint capsule, and release of the capsular insertion from the femoral intertrochanteric line. As trial components of the prosthesis are placed, the position of the released distal capsule in relationship to its original insertion line is an excellent guide to leg length gained, lost, or left unchanged. Methods The radiographs of 80 consecutive primary THAs were reviewed which utilized anterior capsule preservation and direct capsular measurement as a means of assessing change in leg/femoral neck length. Preoperatively, the operative legs were 2.81 +/- 8.5 mm (SD) shorter than the nonoperative leg (range: 17.7 mm longer to 34.1 mm shorter). Postoperatively, the operative legs were 1.05 +/- 5.64 mm (SD) longer than the nonoperative leg (range: 14.9 mm longer to 13.7 mm shorter). Conclusion The preservation and re-assessment of the native anterior hip capsule in relationship to its point of release on the femur is a simple and effective means of determining leg/femoral neck length during DAA THA.
