Context:Patellar tendinopathy is a common condition. There are a wide variety of treatment options available, the majority of which are nonoperative. No consensus exists on the optimal method of treatment.Evidence Acquisition:PubMed spanning 1962-2014.Study Design:Clinical review.Level of Evidence:Level 4.Results:The majority of cases resolve with nonoperative therapy: rest, physical therapy with eccentric exercises, cryotherapy, anti-inflammatories, corticosteroid injections, extracorporeal shockwave therapy, glyceryl trinitrate, platelet-rich plasma injections, and ultrasound-guided sclerosis. Refractory cases may require either open or arthroscopic debridement of the patellar tendon. Corticosteroid injections provide short-term pain relief but increase risk of tendon rupture. Anti-inflammatories and injectable agents have shown mixed results. Surgical treatment is effective in many refractory cases unresponsive to nonoperative modalities.Conclusion:Physical therapy with an eccentric exercise program is the mainstay of treatment for patellar tendinopathy. Platelet-rich plasma has demonstrated mixed results; evidence-based recommendations on its efficacy cannot be made. In the event that nonoperative treatment fails, surgical intervention has produced good to excellent outcomes in the majority of patients.
The current standard of care for prosthetic joint infection includes two-stage arthroplasty, with antibiotic-impregnated cement spacers (ACS) utilized between the stages. We report a 75-year-old woman with previously normal renal function, who developed acute kidney injury (AKI) secondary to biopsy-proven acute tubular necrosis and acute interstitial nephritis after ACS placement containing tobramycin and vancomycin. Peak tobramycin level measured 25.3 mcg/mL, the highest value reported in the literature after ACS placement. Intermittent hemodialysis was initiated with subsequent full recovery of renal function. This paper reviews the published literature regarding the accumulation, toxicity and removal dynamics of aminoglycoside (AG) antibiotics and vancomycin in renal patients. Obtaining serum AG level should be strongly considered in patients experiencing AKI after ACS.Renal replacement therapy may assist in reducing toxic AG levels.
Patients undergoing THA for AVN were more likely to be younger, male, African American, have more medical co-morbidities, and more likely to have a myocardial infarction than those with OA. While the number of primary THAs performed for AVN in the United States has increased over the past ten years, the rate of primary THA for OA increased at a much more rapid rate.
The rate of total knee arthroplasty (TKA) utilization in younger patients (< 65 years old) is increasing. Little is known regarding demographics and in-hospital outcomes in this population. The National Hospital Discharge Survey (NHDS) database was searched using International Classification of Diseases, Ninth Revision (ICD-9) procedure codes for patients admitted to U.S. hospitals for unilateral primary TKA between 2001 and 2010. Patients were separated into young (< 65 years of age) and senior cohorts (≥ 65 years of age). ICD-9 diagnosis and procedure codes were used to identify demographics, hospital length of stay, in-hospital adverse events, mortality, and discharge disposition. Trends were evaluated by linear regression with Pearson correlation coefficient () and statistical comparisons were made using Student -test and chi-square analysis. The young cohort accounted for 38.4% of TKAs performed from 2001 to 2005, increasing to 42.7% of TKAs from 2006 to 2010. They had a higher percentage of males (36.4 vs. 34.2%, < 0.001). Rates of obesity (11.1 vs. 6.0%, < 0.001) and morbid obesity (5.8 vs. 1.9%, < 0.001) were significantly higher, yet they had less comorbidities (4.7 vs. 5.2, < 0.001), and lower rates of transfusion (12.2 vs. 19.8%, < 0.001), pulmonary embolism (PE) (0.31 vs. 0.49%, < 0.020), and mortality (0.03 vs. 0.18%, < 0.001). Patients < 65 years old undergoing TKA have almost double the rate of obesity of patients ≥ 65 years old. This could explain the higher rates of periprosthetic infection and aseptic mechanical failure seen in younger patients. However, the young cohort had a more favorable discharge disposition and lower mortality and risk of PE than elderly patients.
Objectives:It is unknown whether pateints undergoing tenotomy for painful internal snapping at the time of hip arthroscopy can expect equivalent functional outcome to patients undergoing hip arthroscopy without tenotomy. The contribution of the psoas tendon and hip capsule to hip stability is also currently debated. The purpose of this matched study is to (1) compare two-year outcome scores in a study group who underwent psoas tenotomy to a matched control group who did not have a psoas tenotomy, and (2) perform a subgroup analysis of the study group comparing capsular repair to capsular release.Methods:Between April of 2008 and December of 2012, we prospectively collected data and reviewed 694 hip arthroscopies with a minimum 2 year follow up. A total of 243 patients had undergone psoas tenotomy and comprised the study group available for matching. After a power analysis was performed we matched 50 patients in the control group to 50 patients in the study group. A subgroup analysis of the study group was then performed based on the capsular treatment performed. Twenty five patients who underwent capsular release were compared to 25 patients who underwent capsular repair. The protocol included pre- and post-operative administration of four hip-specific patient-reported outcome (PRO) tools, the visual analog scale (VAS), and patient satisfaction scores.Results:Both the study group (n=50) and control group (n=50) demonstrated a statistically significant improvement in patient-reported outcome (PRO) scores and pain scores at 2-year follow up (p<0.05). No statistical differences in PRO scores, pain scores, or patient satisfaction was observed at 2-years between the study group and the control group as well as between the capsular repair and capsular release subgroups.Conclusion:In patients with painful internal snapping and psoas impingement lesions arthroscopic psoas tenotomy appears to result in similar two-year outcomes to patients not undergoing psoas tenotomy at the time of labral treatment. We were unable to detect a significant role for capsular closure at the time of psoas tenotomy; however, this requires further study.
