Background: A trochlear osteotomy aims to restore patellar stability in patients with recurrent patellar instability and trochlear dysplasia. The age of patients at time of surgery could be a relevant factor which influences outcome. We hypothesized that lower age at time of surgery is associated with better patient-reported outcomes.
View Article and Find Full Text PDFBackground: Surgical management of displaced midshaft clavicle fractures in adults leads to better union rates, improved early functional outcomes, and increased patient satisfaction compared with nonoperative treatment. However, both intramedullary fixation and plate osteosynthesis are subject to a specific array of disadvantages and complications. The Anser Clavicle Pin is a novel intramedullary device designed to address these disadvantages and complications.
View Article and Find Full Text PDFIntroduction: In patients with recurrent patellar dislocations, a tibial tubercle osteotomy (TTO) can be indicated to correct patella alta or an increased trochlear groove-tibial tubercle distance. Several surgical techniques are described. Previous studies emphasize that detaching osteotomies results in devascularisation, which can lead to non-union and tibial shaft fractures.

View Article and Find Full Text PDFBackground: Shortening of the fractured clavicle is proposed and debated as an indicator for surgical intervention. There is no standardized or uniform method for imaging and measuring shortening. Different methods and techniques can lead to different measured outcomes.
View Article and Find Full Text PDFBackground: Midshaft clavicle fractures are often associated with a certain degree of shortening. There is great variety in the imaging techniques and methods to quantify this shortening. This study aims to quantify the difference in measurements of shortening and length of fracture elements between 5 views of the fractured clavicle.
View Article and Find Full Text PDFBackground: One of the more commonly used methods of determining the amount of shortening of the fractured clavicle is by comparing the length of the fractured side to the length of contralateral unfractured clavicle. A pre-existing natural asymmetry can make quantification of shortening using this method unreliable. The goal of this study is to assess the side-to-side variation in clavicle length in 100 uninjured, skeletally mature adults.

Methods: Electronic databases (PubMed, EMBASE, and Cochrane) were searched. The 4-point-scale COSMIN checklist was used to evaluate the methodological quality of studies.
Background: The purpose of this study was to compare the mechanical stability of a relatively thin locking plate (FlexitSystem implant) with a relatively firm locking plate (TomoFix implant), both used for opening wedge high tibial osteotomy.
Methods: Seven fresh frozen paired human cadaveric tibiae were used. The opening wedge high tibial osteotomies in the left tibiae were fixated with the FlexitSystem implant and in the right tibiae with the TomoFix implant.
Background: Patient-Reported Outcome (PRO) measurement is a method for measuring perceptions of patients on their health and quality of life. The aim of this paper is to present the results of PRO measurements in total hip and knee replacement as routinely collected during 20 years of surgery in a university hospital setting.
Methods: Data of consecutive patients between 1993 and 2014 were collected.
Background: Developmental dysplasia of the hip (DDH) is a common cause of secondary osteoarthritis (OA) in younger patients, and when end-stage OA develops, a THA can provide a solution. Different options have been developed to reconstruct these defects, one of which is impaction bone grafting combined with a cemented cup. To determine the true value of a specific technique, it is important to evaluate patients at a long-term followup.

Patients And Methods: This study included 92 consecutive cemented femoral revisions performed in our department with a third-generation cementing technique and without instrumented bone impaction grafting between 1996 and 2007.
Syndesmotic disruption occurs in more than 10% of ankle fractures. Operative treatment with syndesmosis screw fixation has been successfully performed for decades and is considered the gold standard of treatment. Few studies have reported the long-term outcomes of syndesmosis injuries.

This rare condition can be treated with arthroscopic debridement with volume reduction of the anterior cruciate ligament.
View Article and Find Full Text PDFBackground: Reconstructing the medial patellofemoral ligament (MPFL) has become a key procedure for stabilizing the patella. Different techniques to reconstruct the MPFL have been described: static techniques in which the graft is fixed rigidly to the bone or dynamic techniques with soft tissue fixation. Static MPFL reconstruction is most commonly used.

Purpose: To prospectively evaluate the diagnostic performance of magnetic-resonance-arthrography (MRA) by experienced musculoskeletal radiologists in patients with traumatic-anterior-shoulder-instability (TASI), after feedback protocol execution.
Materials And Methods: Forty-five surgically confirmed MRA's were used to enhance personal feedback, to discuss differences in outcome between MRA assessment and surgical findings and to fine-tune definition interpretation agreement of 7 different TASI-related lesions, between experienced musculoskeletal radiologists and experienced orthopaedic shoulder surgeons. After execution of the feedback protocol 20 new, surgically confirmed, MRA's were assessed by 2 experienced musculoskeletal radiologists using a seven-lesion standardized scoring form.
Purpose: To evaluate the mid- to long-term results of the Richards' type II patellofemoral arthroplasty (PFA) in terms of functional scores, number and type of complications, patient satisfaction and survival.
Methods: We retrospectively studied patients that received a Richards' type II PFA at our institution between 1998 and 2007. Patients with a functioning PFA at the time of this study were evaluated.
Background: We compared the diagnostic reproducibility and accuracy of musculoskeletal radiologists with orthopaedic shoulder surgeons in 2 large medical centers in assessing magnetic resonance arthrograms (MRAs) of patients with traumatic anterior shoulder instability.
Methods: Forty-five surgically confirmed MRAs were assessed by 4 radiologists, 4 orthopaedic surgeons, 2 radiologic teams, and 2 orthopaedic teams. During MRA assessment and surgery, the same 7-lesion scoring form was used.
Background: The increasing number of total hip arthroplasties (THAs) performed in younger patients will inevitably generate larger numbers of revision procedures for this specific group of patients. Unfortunately, no satisfying revision method with acceptable survivorship 10 years after revision has been described for these patients so far.
Questions/purposes: The purposes of this study were to (1) analyze the clinical outcome; (2) complication rate; (3) survivorship; and (4) radiographic outcome of cemented revision THA performed with impaction bone grafting (IBG) on both the acetabular and femoral sides in one surgery in patients younger than 55 years old.
Purpose: It is often a difficult decision whether it is safe to perform revision hip surgery in a patient of 80 years and older. Therefore we evaluated the results of cemented revisions in these elderly patients.
Methods: Clinical data, radiographs and complications of 49 consecutive cup and/or stem revisions in 48 patients were prospectively collected.
Purpose: Patients suffering from post traumatic osteoarthritis of the acetabulum often require a total hip arthroplasty at a relatively young age. Long-term data outcome studies for this population are lacking. We report on the long-term outcome of 20 acetabular fractures in 20 patients treated with impaction bone grafting and a cemented cup after a mean follow-up of 18 years (range, 12-26 years).

The assessment of satisfaction is difficult because it is a multifactorial item for which no golden standard exists. One of the potential methods of measuring satisfaction is by using the well-known visual analogue scale (VAS).

Purpose: The purpose of this study was to investigate whether nocturnal pain and pain at rest preoperatively influence the satisfaction in patients after joint arthroplasty. The second research question is whether subjective outcome (VAS/WOMAC) after hip (THA) or knee arthroplasty (TKA) differs in patients with or without nocturnal pain and pain at rest preoperatively compared to those who do not.
Methods: A consecutive group of 189 TKAs and 189 THAs was evaluated.
