Revision Risk of Unipolar and Bipolar Hemiarthroplasties in the Dutch Arthroplasty Register.

Background: Hemiarthroplasty (HA) for hip fractures can be performed with a unipolar or bipolar head. We describe the use of unipolar and bipolar HA after a hip fracture in the Netherlands and determined revision rates and risk factors.

Methods: All HAs for an acute hip fracture registered in the Dutch Arthroplasty Register (LROI) during 2007 to 2021 were included; 44,127(88%) unipolar and 6,013(12%) bipolar HAs.

The prognosis of ankle fractures: a systematic review.

The aim of this study was to update the scientific evidence for ankle fracture prognosis by addressing radiographic osteoarthritis, time course and prognostic factors. A systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Studies were included if they were randomized controlled trials, controlled trials or observational studies, including case series and case-control studies investigating radiologically confirmed osteoarthritis in adults with a classified ankle fracture, treated with or without surgery, with a minimum follow-up of 1 year.

Comparable mortality but higher revision rate after uncemented compared with cemented total hip arthroplasties in patients 80 years and older: report of 43,053 cases of the Dutch Arthroplasty Register.

Background and purpose - Mortality and revision risks are important issues during shared decision-making for total hip arthroplasty (THA) especially in elderly patients. We examined mortality and revision rates as well as associated patient and prosthesis factors in primary THA for osteoarthritis (OA) in patients ≥ 80 years in the Netherlands. Patients and methods - We included all primary THAs for OA in patients ≥ 80 years in the period 2007-2019.

Low revision rate of dual mobility cups after arthroplasty for acute hip fractures: report of 11,857 hip fractures in the Dutch Arthroplasty Register (2007-2019).

Background and purpose - Dislocation is one of the most frequent reasons for cup revision after total hip arthroplasty (THA) for an acute fracture. A dual mobility cup (DMC) might reduce this risk. We determined the cup revision rate after THA for an acute fracture according to type of cup.

Lower 5-year cup re-revision rate for dual mobility cups compared with unipolar cups: report of 15,922 cup revision cases in the Dutch Arthroplasty Register (2007-2016).

Background and purpose - During revision hip arthroplasty the dual mobility cup (DMC) is widely used to prevent dislocation despite limited knowledge of implant longevity. We determined the 5-year cup re-revision rates of DMC compared with unipolar cups (UC) following cup revisions in the Netherlands. Patients and methods - 17,870 cup revisions (index cup revision) were registered in the Dutch Arthroplasty Register during 2007-2016.

Dual mobility cups in primary total hip arthroplasties: trend over time in use, patient characteristics, and mid-term revision in 3,038 cases in the Dutch Arthroplasty Register (2007-2016).

Background and purpose - We noticed an increased use of dual mobility cups (DMC) in primary total hip arthroplasty (THA) despite limited knowledge of implant longevity. Therefore, we determined the trend over time and mid-term cup revision rates of DMC compared with unipolar cups (UC) in primary THA. Patients and methods - All primary THA registered in the Dutch Arthroplasty Register (LROI) during 2007-2016 were included (n = 215,953) and divided into 2 groups - DMC THA (n = 3,038) and UC THA (n = 212,915).

Higher mid-term revision rates of posterior stabilized compared with cruciate retaining total knee arthroplasties: 133,841 cemented arthroplasties for osteoarthritis in the Netherlands in 2007-2016.

Background and purpose - The preference for a cruciate retaining (CR) or posterior stabilized (PS) TKA (total knee arthroplasty) system varies greatly between Dutch hospitals, independent of patient characteristics. We examined mid-term revision rates for men and women of different age categories. Patients and methods - We included all 133,841 cemented fixed-bearing primary CR or PS TKAs for osteoarthritis reported in the Dutch Arthroplasty Register (LROI) in 2007-2016.

Gastrocnemius recession: A cadaveric study of surgical safety and effectiveness.

Background and purpose - Many methods of gastrocnemius lengthening have been described, with different surgical challenges, outcomes, and risks to the sural nerve. Our aims were (1) to locate the gastrocnemius muscular-tendinous junction in relation to the mid-length of the fibula (from here on designated the mid-fibula), (2) to compare the dorsiflexion achieved with dorsal recession or ventral recession, and (3) to determine the risk of injury to the sural nerve during gastrocnemius recession. Methods - In 10 pairs of fresh-frozen adult cadaveric lower extremities transected above the knee, we measured dorsiflexion, performed dorsal or ventral gastrocnemius recession at the mid-fibula, and then measured the increase in dorsiflexion and fasciotomy gap.

[Unexplained pain in the ankle and foot. Consider transient osteoporosis].

Transient osteoporosis is an increasingly recognized condition that causes severe pain in weight-bearing joints and is characterized by otherwise unexplained bone-marrow oedema on MRI. We present two patients, a 40-year-old man and a 60-year-old woman, with longstanding severe pain in the foot and ankle. Both had invalidating pain with only mild swelling of the foot or ankle.

Dual mobility acetabular component in revision total hip arthroplasty for persistent dislocation: no dislocations in 50 hips after 1-5 years.

Background: A dual mobility cup has the theoretic potential to improve stability in primary total hip arthroplasty (THA) and mid-term cohort results are favorable. We hypothesized that use of a new-generation dual mobility cup in revision arthroplasty prevents dislocation in patients with a history of recurrent dislocation of the THA.

Materials And Methods: We performed a retrospective cohort study of patients receiving an isolated acetabular revision with a dual mobility cup for recurrent dislocation of the prosthesis with a minimum follow-up of 1 year.

Health care use of patients with osteoarthritis of the hip or knee after implementation of a stepped-care strategy: an observational study.

Objective: To enhance guideline-based nonsurgical management of osteoarthritis (OA), a multidisciplinary stepped-care strategy has been implemented in clinical practice. This study aimed to describe health care use after implementation of this strategy and to identify factors related to such use at multiple levels.

Methods: For this 2-year observational prospective cohort, patients with symptomatic hip or knee OA were included by their general practitioner.

Effect of stepped care on health outcomes in patients with osteoarthritis: an observational study in Dutch general practice.

Background: A stepped care strategy (SCS) to improve adequate healthcare use in patients with osteoarthritis was developed and implemented in a primary care region in the Netherlands.

Aim: To assess the association between care that is in line with the SCS recommendations and health outcomes.

Design And Setting: Data were used from a 2-year observational study of 313 patients who had consulted their GP because of osteoarthritis.

Non-surgical care in patients with hip or knee osteoarthritis is modestly consistent with a stepped care strategy after its implementation.

Objective: To improve the management of hip or knee osteoarthritis (OA), a stepped care strategy (SCS) has been developed that presents the optimal sequence for care in three steps. This study evaluates the extent to which clinical practice is consistent with the strategy after implementation and identifies determinants of SCS-consistent care.

Design: A 2-year observational prospective cohort study.

The use of a dual-mobility concept in total hip arthroplasty patients with spastic disorders: no dislocations in a series of ten cases at midterm follow-up.

Introduction: Total hip arthroplasty (THA) is one of the treatment options in patients with cerebral palsy (CP) with painful osteoarthritis of the hip. However, the risk of dislocation of the prosthesis is higher in patients with CP when compared with physically normal patients. In this retrospective study of ten consecutive cases, we hypothesized that the use of a dual-mobility cup could reduce this risk of dislocation combined with good functional results.

Agreement of general practitioners with the guideline-based stepped-care strategy for patients with osteoarthritis of the hip or knee: a cross-sectional study.

Background: To improve the management of hip or knee osteoarthritis (OA), a multidisciplinary guideline-based stepped-care strategy (SCS) with recommendations regarding the appropriate non-surgical treatment modalities and optimal sequence for care has been developed. Implementation of this SCS in the general practice may be hampered by the negative attitude of general practitioners (GPs) towards the strategy. In order to develop a tailored implementation plan, we assessed the GPs' views regarding specific recommendations in the SCS and their working procedures with regard to OA.

Joint-pain comorbidity, health status, and medication use in hip and knee osteoarthritis: a cross-sectional study.

Objective: To determine the prevalence of joint-pain comorbidities in individuals with hip or knee osteoarthritis (OA) and to assess the differences in the characteristics of people with and without joint-pain comorbidities.

Methods: In this cross-sectional study, individuals referred to secondary care for treatment of hip/knee OA completed questionnaires to determine sociodemographic characteristics, disease-related outcomes, and joint-pain comorbidities. Joint-pain comorbidity was defined as pain perceived in a joint, other than the index joint, for more than half of the days in the preceding month.

Chronic instability of the anterior tibiofibular syndesmosis of the ankle. Arthroscopic findings and results of anatomical reconstruction.

Background: The arthroscopic findings in patients with chronic anterior syndesmotic instability that need reconstructive surgery have never been described extensively.

Methods: In 12 patients the clinical suspicion of chronic instability of the syndesmosis was confirmed during arthroscopy of the ankle. All findings during the arthroscopy were scored.

"Beating osteoARThritis": development of a stepped care strategy to optimize utilization and timing of non-surgical treatment modalities for patients with hip or knee osteoarthritis.

Inadequacies in health care practices have been reported despite existing guidelines to manage hip or knee osteoarthritis. To facilitate guideline implementation and improve utilization of non-surgical treatment options a care strategy should be developed. This study describes the development of an evidence-based, multidisciplinary, patient-centered, stepped care strategy.

Foot function after fusion of the first metatarsophalangeal joint.

Background: We measured with a validated score the operative outcome in patients without concomitant foot surgery who underwent fusion of the first metatarsophalangeal (MTP) joint for hallux rigidus (HR) and hallux valgus (HV). We also examined whether there is a correlation between foot function and hallux position to try to formulate an optimum fusion angle.

Materials And Methods: Between 2002 and 2005, a consecutive series of 62 patients underwent crossed screw fusion of the first MTP joint (27 HR and 35 HV) without concomitant surgery of the same or contralateral foot or had previous surgery of the same foot.

[Conservative treatment of hip and knee osteoarthritis: a systematic, step-by-step treatment strategy].

In the Netherlands the current, conservative management of osteoarthritis of the hip and knee is heterogeneous and suboptimal. Existing guidelines only provide indications for certain interventions, but they do not provide recommendations about the sequence of these treatments. A step-by-step treatment strategy has now been developed in addition to the guidelines.

[Guideline 'Diagnostics and treatment of osteoarthrosis of the hip and knee'].

In patients with osteoarthritis of the hip or knee, radiological examinations are only indicated in general practice if there is discrepancy between the history and the findings in the physical examination. The treatment of first choice is a combination of physiotherapy and oral analgesics. If paracetamol fails to reduce the pain sufficiently, NSAIDs can be prescribed.
