Tennis elbow is the most common cause of lateral-sided elbow pain with a major socioeconomic impact. The etiology of tennis elbow is not completely understood, but there are many different treatment options. This review gives an overview of the current concepts of diagnosis and treatment of tennis elbow and the impact on work participation.
Background: Diagnosing capitellar osteochondritis dissecans (OCD) can be difficult, causing delay in treating young athletes. The main aim of this retrospective diagnostic study was to determine which radiological technique is preferred to identify and classify elbow OCD. Methods: We identified young patients who underwent elbow arthroscopy because of symptomatic OCD. We included all patients who had pre-operative radiographs, a computed tomography (CT) scan and magnetic resonance imaging (MRI) available. We assessed whether the osteochondral lesion could be identified using the various imaging modalities. All lesions were classified according to previous classifications for X-ray, CT and MRI, respectively. These results were compared with findings at arthroscopy. Results: Twenty-five patients had pre-operative radiographs as well as CT scans and MRI. In six patients, the lesion was not visible on standard X-ray. In 20 patients, one or two loose bodies were found during surgery, consistent with an unstable lesion. Pre-operatively, this was seen on 11 X-rays, 13 MRIs and 18 CT scans. Conclusions: Capitellar OCD lesions are not always visible on standard X-rays. A CT appears to be the preferred imaging technique to confirm diagnosis of OCD. Loose bodies are often missed, especially on standard X-rays and MRIs.
Introduction Range of motion (ROM) is closely monitored before and after surgery for stiff elbow and during rehabilitation. Measurements in the home environment may be helpful to increase involvement and adherence of the patient. Therefore, our objective is to investigate the validity and inter- and intraobserver reliability of 3 alternative methods to assess the ROM by the patient in a home-based situation, in comparison to the universal goniometer (UG). We hypothesize that all 3 alternative methods will be valid alternatives and show a level of reliability equivalent to UG. Methods Goniometric measurements of elbow flexion, extension, pronation and supination using photography, movie, and a smartphone application were obtained. The validity of these measurement methods was compared to UG. The interobserver and intraobserver reliability were calculated for all measurement methods. Results Photography and movie based goniometry of the elbow showed good validity in flexion and extension. The interobserver and intraobserver reliability were found to be good to excellent for photo and movie but moderate to poor for UG and the smartphone application. Conclusions Photo or movie based goniometry seems to be a useful option for initial and follow-up measurement of the elbow ROM, both in the outpatient clinic and in a home environment. Based on our study, the smartphone application we used is not recommended.
Injections carried out manually for the treatment of LE are not accurate, resulting in the majority being localized intra-articular. For future research to the effect of injection therapy in the treatment of LE, it is important that injections should be performed in a reproducible and standardized way.
Background
In the treatment of Lateral Epicondylitis (LE) no single intervention concerning injection therapies has been proven to be the most effective with regard to pain reduction. In this trial 3 injection therapies (perforation with application of autologous blood, perforation with application of dextrose and perforation only) will be compared in a standardized and ultrasound guided way. The objective is to assess the effectiveness of these 3 injection therapies on pain, quality of life and functional recovery. By conducting this study, we hope to make a statement on the effectiveness of injection therapy in the treatment of LE. Hereby, unnecessary treatments can be avoided, a more universal method of treatment can be established and the quality of the treatment can be improved.
Methods/design
A multicenter, randomized controlled trial with a superiority design and 12 months follow-up will be conducted in four Dutch hospitals. One hundred sixty five patients will be recruited in the age of 18 to 65 years, with chronic symptomatic lateral epicondylitis lasting longer than 6 weeks, which have concordant pain during physical examination. Patients will be randomized by block randomization to one of the three treatment arms. The treatment will be blinded for patients and outcome assessors. The following three injection therapies are compared: perforation with application of autologous blood, perforation with application of dextrose and perforation only. Injections will be performed ultrasound guided in a standardized and automated way. The primary endpoint is: pain (change in ‘Visual Analogue Scale’). Secondary endpoints are quality of life and functional recovery. These measurements are collected at baseline, 8 weeks, 5 months and 1 year after treatment.
Discussion
When completed, this trial will provide evidence on the effectiveness of injection therapy in the treatment of lateral epicondylitis on pain, quality of life and functional recovery. In current literature proper comparison of the effectiveness of injectables for LE is questionable, due to the lack of standardization of the treatment. This study will overcome bias due to manually performed injection therapy.

The analgesic effect of local infiltration analgesia (LIA) after total knee arthroplasty (TKA) has been reported to be less than 24 hours. The concept of continuous LIA (CLIA) has been developed to achieve prolonged analgesia by bolus injections or by pump infusion of analgesics. The purpose of this meta-analysis is to assess the effect of CLIA versus single-shot injection LIA (SLIA) and placebo on pain after TKA.A systematic search was performed in most relevant databases to identify all randomized controlled trials (RCTs) comparing intra-articular CLIA with SLIA or placebo for TKA. Primary outcome measures were visual analogue scale (VAS)-scores after 24, 48, and 72 hours at rest and during activity. Data were extracted for meta-analysis and pooled using Cochrane software. The results of comparable studies were pooled using the fixed effects model or random effects model.A total of 11 RCTs were included. Five articles were eligible for meta-analysis comparing CLIA versus placebo, involving 227 TKAs. VAS scores at rest 24 hours after surgery were in favor of CLIA with a decrease of pain scores of 46%. On the second and third postoperative day, the decrease in VAS scores was no longer significant. During activity VAS scores were also in favor of CLIA after 24 and 48 hours.Two studies were eligible for meta-analysis comparing CLIA versus SLIA. VAS scores at rest, 48 hours after surgery, were in favor of CLIA. CLIA can possibly provide a reduced pain perception for 24 hours postoperative at rest after performing a TKA. This effect may persist until 48 hours postoperative during activity. Due to the high level of heterogeneity no firm further conclusions can be drawn.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
