Main reasons for prolonged hospital stay after total knee arthroplasty (TKA) are postoperative nausea and vomiting (PONV) and pain. Having a positive effect on both PONV and pain, perioperative administration of corticosteroids might improve rehabilitation and reduce length of hospital stay (LOS) after TKA. Aim of this review is to determine the ef...

A key component in fast-track total knee arthroplasty (TKA) is early mobilization. Preoperative fasting might cause orthostatic hypotension and -intolerance which both can interfere with early mobilization. It was hypothesized that consuming a carbohydrate drink 2-3 hours prior to surgery is a viable option to reduce orthostatic hypotension, and as...

Background and purpose: Aseptic loosening, mainly caused by migration, is one of the most common indications for revisions in unicompartmental knee arthroplasty (UKA). In this study, we investigated the early migration of the Persona Partial Knee (PPK, Zimmer Biomet, Warsaw, IN), a cemented medial fixed-bearing unicompartmental knee prosthesis, and...

Background and purpose — Early functional outcome after total knee arthroplasty (TKA) has been described before, but without focus on the presence of certain functional recovery patterns. We investigated patterns of functional recovery during the first 3 months after TKA and determined characteristics for non-responders in functional outcome. Patie...

PurposePostoperative mortality is commonly reported as outcome measurement after total knee arthroplasty (TKA). Mortality might be influenced by multiple factors including cementation of the prosthesis. Until now, the influence of cementation on early and late mortality after TKA is unknown. The aim of the present study was to determine the effect...

Abstract Background To evaluate the reliability of two different techniques for measuring penetration and distribution of the cement mantle in the proximal tibia after total knee arthroplasty (TKA) with Computer Tomography (CT) in vivo. Methods Standardized CT scans of the proximal tibia were taken 1 to 2 years after total knee arthroplasties impla...

Background: With an increasingly younger population and more active patients, assessment of functional outcome is more important than ever in patients undergoing total knee arthroplasty. Accelerometers have been used successfully to objectively evaluate gait quality in other fields. The aim of this study was to assess gait quality with acceleromet...

Background More personalized implant designs for total knee arthroplasty might optimize the clinical outcome after surgery. One of these personalized implant designs is the Persona knee implant system (Zimmer Biomet, Warsaw, Indiana, USA). The primary objective of this study was to determine patient reported outcomes and implant survivorship of the...

Preoperative planning is an important phase of total joint arthroplasty. Current template programs and methods only provide moderate accuracy for implant size prediction. Recently, a relationship between shoe size and implant size was found. We hypothesized that shoe size shows a high percentage of agreement for implant size of both femoral and tib...

Purpose: Early mobilization is an important aspect of fast-track protocols and intrathecal bupivacaine is often used in primary total knee arthroplasty (TKA). Although the optimal dose is not known, conventional doses leave patients unable to mobilize for two to four hours. The dose of an intrathecally administered local anesthetic should therefor...

IntroductionA Bankart procedure is a surgical technique for the repair of recurrent shoulder joint dislocations. This study reports the long-term results of the ‘open’-modified Bankart procedure. Methods We performed a retrospective cohort study in which patients are studied who had open-modified Bankart surgery for instability problems in the abse...

Background and purpose: Effective analgesia is essential for postoperative recovery and rehabilitation in TKA. The challenge of analgesic regimes is to obtain adequate pain relief and maximum muscle control to mobilize and rehabilitate patients early. However, the optimal dose and best composition are not known. We hypothesized that there would be...

Background: The main objective of this prospective randomized study was to compare the clinical and radiographic outcomes of the mini-midvastus (MMV) approach with the conventional approach for total knee arthroplasty at the 5-year follow-up. Methods: Ninety-seven patients (100 knees) with osteoarthritis were assigned to the MMV group or to a gr...

We retrospectively reviewed all 147 medial UKA's placed between 2001 and 2011 with a minimum follow-up of two years. The VAS for pain and satisfaction, the New Knee Society Score (KSS) for satisfaction and the Knee Injury and Osteoarthritis Outcome Score (KOOS) were used as patient reported outcomes (PROs). Pre-operative and follow-up radiographs o...

Background In total knee arthroplasty (TKA), cement penetration between 3 and 5 mm beneath the tibial tray is required to prevent loosening of the tibia component. The objective of this study was to develop and validate a reliable in vivo measuring technique using CT imaging to assess cement distribution and penetration depth in the total area unde...

A 23-year-old morbidly obese woman (BMI: 62,5 kg/m2) came to the ER because of a painful right knee. When walking the knee had collapsed spontaneously. Physical examination of the right leg was not possible due to pain. Examination of the unaffected left leg revealed multi-directional instability. A radiograph showed anterior luxation of the tibia.

The Oxford Shoulder Score (OSS) is an internationally-used patient-based outcome score. Up to now, it was not validated in Dutch. The purpose of this study was to produce a Dutch translation of the OSS and to test this version in terms of reliability and validity. Translation of the OSS was done according to the guidelines in literature. One hundre...

Pilot P, Vehmeijer SBW, Verburg H, Cornelisse HB, Bloem RM, Stand van zaken rond de totale heup- en knieartroplastiek. Huisarts Wet 2009;52(11):542-6. De totale heupoperatie en de knievervangende operatie zijn zeer succesvolle ingrepen, gelet op de verbetering van de kwaliteit van leven. Voor de levensduur van zowel een heup als een knie mag minim...

We report the outcome of a modified Bankart procedure using suture anchors in 31 patients (31 shoulders) with a mean follow-up of 11 years (10 to 15). The mean age of the patients was 28 years (16 to 39). At follow-up, the mean Rowe score was 90 points (66 to 98) and the Constant score was 96 points (85 to 100). A total of 26 shoulders (84%) had a...

Treatment of avascular necrosis (AVN) of the femoral head with a vascularized iliac bone graft was studied in nine patients (12 hips). The condition of the femoral head was classified radiographically before and after surgery. Magnetic resonance (MR) imaging was performed to demonstrate the extent and signal intensity characteristics of the area of...

Complete rupture of the tendon of the M. biceps femoris proximal to its insertion is a rare occurrence. Relatively few patients have been recorded. We describe a patient with a complete rupture sustained as a result of a water skiing accident, viz. a fall over the stern wave. The case history was in accordance with a theory about the cause of this...
