Project description:Achondroplasia is the most common form of dwarfism in humans and is orthopedically characterized by shortened extremities and an exaggerated lumbar lordosis. The surgical challenges are maintenance of axial alignment during limb lengthening as well as joint preservation and alignment restoration.We present a 46-year-old female suffering from achondroplasia with severe pain in both knees. Severe varus deformities of both femurs and degeneration of both knee joints became apparent on clinical and radiological examination. On each femur, we performed one-staged, lateral closed-wedge osteotomy, and total knee arthroplasty (TKA). Subsequently, the patient was relieved of knee joint pain and gained a greater range of motion.One-staged valgization osteotomy and concomitant TKA represents a challenging, yet reasonable, surgical solution in axially severe malaligned and joint degenerated patients.

Project description:The Mycoplasma hominis infection is a rare postoperative complication after joint replacement. Based on our knowledge, there were only two cases reported by Korea all over the world currently. A case of postoperative Mycoplasma hominis infection after total knee replacement in our hospital was reported in this article. It was confirmed through mass spectrometer and Mycoplasma cultivation and treated by the first stage debridement, polyethylene insert replacement, and then drainage and irrigation combined with sensitive antibiotics after the operation. We observed that the C reactive protein (CRP) level correlates with the development of disease, while the erythrocyte sedimentation rate (ESR) remains at a high level, indicating the relevance between the Mycoplasma hominis infection caused by knee joint replacement and CRP. This study aims to report the case and review relevant literature.

Project description:Introduction and importanceTotal femoral replacement (TFR) is a salvage surgical procedure that has been indicated mainly for oncologic indication to avoid lower limb amputation but has recently been indicated for non-oncological disorders.Case presentationWe report the case of a 63-year-old male with chronic osteomyelitis of the left femur, severe pain and bone deformation, the risk of amputation in this patient was very high. The patient underwent total femur replacement (TFR) with a modular mega-prosthesis. TFR was conducted in two phases. The first one consists of femur resection followed by placement of antibiotic cement; and the second operation was performed after 7 weeks, in which a modular mega-prosthesis was implanted. After a 2-month rehabilitation period, the patient recovered basic ambulation without any complaint of pain or detectable residual infection. The 1-year follow-up was uneventful, with no residual pain or infection. The patient retains normal ambulation and daily function.Clinical discussionChronic persistent osteomyelitis is a hard to manage non-neoplastic disorder that leads to amputation in severe cases. In such patients, TFR would be considered as a salvage therapy that could preserve the patient's anatomical integrity and ambulation.ConclusionTo the best of our knowledge, this is the first case of TFR for treatment of chronic persistent osteomyelitis in Vietnam. While TFR are still mainly indicated for oncology patients, TFR is anticipated to be performed more frequently for non-oncological disorders where there are extensive femoral bone loss and risk of amputation.

Project description:BackgroundThe quality and state of satisfaction reporting after total knee replacement (TKR) is variable.Questions/purposesThe purposes of this systematic review were (1) to examine the available literature on patient satisfaction after TKR, (2) to evaluate the quality of available evidence, and (3) to identify predictors of patient satisfaction after TKR.MethodsA systematic review of the MEDLINE database was performed. The initial search yielded 1219 studies. The inclusion criteria were English language, clinical outcome study with primary outcome related to TKR for osteoarthritis, and patient-reported satisfaction included as an outcome measure. Studies were assessed for demographics, methodology for reporting satisfaction, and factors influencing satisfaction.ResultsTwo hundred eight studies, including 95,560 patients who had undergone TKR, met all inclusion and exclusion criteria; 112 (53.8%) of these studies were published in the past 3 years. Satisfaction was most commonly measured using an ordinal scale. Twenty-seven studies (13%) used a validated satisfaction survey. Eighty-three percent of studies reported more than 80% satisfaction. The most commonly reported predictor of satisfaction was post-operative patient-reported functional outcome. Pre-operative anxiety/depression was the most common pre-operative predictor of dissatisfaction.ConclusionThere are numerous studies reporting patient satisfaction after TKR, and publication on the topic has been increasing over the past decade. However, the majority of studies represent lower levels of evidence and use heterogeneous methods for measuring satisfaction, and few studies use validated satisfaction instruments. In general, the majority of studies report satisfaction rates ranging from 80 to 100%, with post-operative functional outcome and relief of pain being paramount determinants for achieving satisfaction.

Project description:Maintenance or restoration of a good range of motion of the knee is one of the most important outcomes following knee surgery. According to previous studies, opening wedge high tibial osteotomy enables better recovery of range of motion in knee flexion than that achievable after total knee arthroplasty or unicompartmental knee arthroplasty. However, few reports provide a detailed description of the postoperative recovery of knee extension range of motion after opening wedge high tibial osteotomy. We describe our experience with a knee extension training program using a single-joint hybrid assistive limb device (HAL-SJ; Cyberdyne Inc., Tsukuba, Japan) during the acute recovery phase after opening wedge high tibial osteotomy. The HAL-SJ is a wearable robotic device that facilitates voluntary control of knee joint motion.A 67-year-old Japanese woman who underwent opening wedge high tibial osteotomy for spontaneous osteonecrosis of the left medial femoral condyle received HAL-SJ-based knee extension training postoperatively. Our experience with this patient revealed that knee extension training with the HAL-SJ during the acute phase following opening wedge high tibial osteotomy is feasible. Furthermore, the patient's knee extension range of motion improved to values similar to those seen during the preoperative stage, and her flexion range of motion was improved at 3 months after the surgery.HAL-SJ-based knee extension training could be used as a novel post-opening wedge high tibial osteotomy rehabilitation modality. Further exploration of individualized optimal settings of the HAL-SJ is required to improve its safety and efficacy.

Project description:Total hip replacement (THR) is a highly successful operation in alleviating pain and improving the overall function of the hip, in end-stage arthritis of the hip, in otherwise fit patients. However, THR as a surgical option in post-traumatic hip arthritis with ipsilateral above-knee amputation is rarely reported.We are presenting a case report of a 30-year-old male, who had previously underwent an above-knee amputation due to road-traffic accident, presenting 24 h after the injury with segmental fracture femur and popliteal artery laceration, for which the limb could not be salvaged. He had an impacted anteroinferior dislocation of the ipsilateral hip with significant cartilage damage of the femoral head which required open reduction. Subsequently, he developed traumatic arthritis of the involved hip which required conversion to an uncemented THR, using a minimally invasive (MIS) anterolateral approach. The preoperative management, surgical technique, and postoperative rehabilitation are described to highlight the technical challenges, these lower limb amputees may present along with review of literature of such rare cases.THR in an above-knee amputee with posttraumatic hip arthritis using MIS technique is an encouraging surgical option for early functional recovery and minimizing surgical complications.

Project description:Uterine leiomyoma (UL) is the most common benign smooth muscle tumour of the premenopausal women. Rarely it shows malignant behaviour by metastasizing through the pelvic veins into systemic veins, inferior vena cava (IVC), there it is termed as intravenous leiomyomatosis (IVL). IVL may restrict itself within the IVC or it may extend into right heart chambers reaching up to pulmonary arteries. Here we report a case of single staged excision of intracardiac(IC) extension of IVL of a 45 -year -old premenopausal women, who have undergone abdominal hysterectomy five years ago, with the complaints of shortness of breath aggravated on bending forward for the past two years.

Project description:Background:Total knee arthroplasty (TKA) in the setting of a prior contralateral above-knee amputation (AKA) represents a rare scenario with limited reported outcomes. As such, it is difficult for surgeons to effectively counsel these patients relative to risks and expected outcomes after TKA. We report outcomes for a series of 10 such patients. Methods:We retrospectively reviewed all patients at our institution from 2005 to 2018 who underwent a primary TKA and prior contralateral AKA and had a minimum 12-month follow-up. Data regarding complications, ambulatory status, reported pain, patient demographics, length of follow-up, and comorbidities were obtained. Results:Ten patients met criteria. Follow-up ranged from 1 to 8 years. Six reported no pain or improved pain with weight-bearing. Ambulatory status worsened for 5 patients, remained unchanged for 3, and improved for 2. Five patients had significant postoperative complications: infection requiring repeat surgery (3), quadriceps tendon rupture (1), and revision for implant failure and instability (1). Patients in this cohort had a median of 3 medical comorbidities known to affect postoperative outcomes and complication rates. Conclusions:While a contralateral AKA is not an absolute contraindication to TKA, these results should influence patient counseling. Most of our cohort benefited from improved pain, but only 2 of 10 had improved ambulation and half had significant complications. Medical comorbidities may have contributed to these complications. Surgeons contemplating TKA in this situation might consider modified postoperative recovery protocols and aggressive preoperative optimization of medical comorbidities to lower the risk of complication in this high-risk population.

Project description:BackgroundKnee extensor strength and knee extension range of motion (ROM) are important predictors of physical function in patients with a total knee arthroplasty (TKA). However, the relationship between the two knee measures remains unclear. The purpose of this study was to examine whether changes in knee extensor strength mediate the association between changes in knee extension ROM and self-report physical function.MethodsData from 441 patients with a TKA were collected preoperatively and 6 months postoperatively. Self-report measure of physical function was assessed by the Short Form 36 (SF-36) questionnaire. Knee extensor strength was measured by handheld dynamometry and knee extension ROM by goniometry. A bootstrapped cross product of coefficients approach was used to evaluate mediation effects.ResultsMediation analyses, adjusted for clinicodemographic measures, revealed that the association between changes in knee extension ROM and SF-36 physical function was mediated by changes in knee extensor strength.ConclusionsIn patients with TKA, knee extensor strength mediated the influence of knee extension ROM on physical function. These results suggest that interventions to improve the range of knee extension may be useful in improving knee extensor performance.

Project description:BackgroundDespite potential concerns regarding their validity, physician-rating websites continue to grow in number and utilization and feature prominently on major search engines, potentially affecting patient decision-making regarding physician selection.Questions/purposesWe sought to determine whether patient ratings on public physician-rating websites correlate with surgeon-specific outcomes for high-volume total knee replacement (TKR) surgeons in New York State (NYS) from 2010 to 2012.MethodsOnline patient ratings were compared to surgeon-specific outcomes from the Statewide Planning and Research Cooperative System (SPARCS) database from the NYS Department of Health. For each surgeon, we determined the infection rate, re-admission rate, and revision surgery rate within the study period, as well as the mean inpatient length of stay, for TKR from the SPARCS database. Online ratings were collected from two physician-rating websites (Vitals.com and HealthGrades.com).ResultsOne hundred seventy-four high-volume TKR surgeons were identified in NYS from 2010 to 2012. The mean rates of in-hospital infection, 90-day infection, 30-day re-admission, 90-day re-admission, and revision surgery were 0.25, 1.00, 4.89, 8.43, and 1.31%, respectively. The mean number of ratings for individual surgeons on HealthGrades.com and Vitals.com were 24.0 (range: 0 to 109) and 19.3 (range: 0 to 114), respectively, and mean overall ratings were 4.2 and 4.1 (out of 5) stars, respectively. As with online patient ratings of individual surgeons, variability was observed in the total adverse event rate distribution for individual surgeons. Despite sufficient variability in both online patient rating and surgeon-specific outcomes for high-volume TKR surgeons in NYS, no correlation was observed.ConclusionThere was no correlation between surgeon-specific TKR outcome measures and online patient ratings. We therefore advise that patients exert caution when interpreting ratings on these websites.
