Near-Optimal Recovery Within 3 Months:Investigating Health-Related Quality of Life and Functional Outcomes After Single-Stage Bilateral Hip Replacement for Osteoarthritis

Single-stage bilateral hip replacement (SSBHR) is a safe and successful orthopaedic intervention for patients suffering from bilateral osteoarthritis of the hip. Data on short- and mid-term recovery outcome studies are, unfortunately, scarce. The purpose of this study was to investigate the change in the functional measures and quality of life after SSBHR and to determine the patient's willingness to undergo the same procedure again. Data were prospectively collected and analyzed from patients with bilateral symptomatic hip osteoarthritis who underwent SSBHR from January 2019 until December 2020. Patients were excluded only if they failed to sign an informed consent or were unable to fill out questionnaires due to language or cognitive problems. Preoperatively and 3 and 12 months after surgery, health-related quality of life (HRQOL) and physical functioning were measured. Twelve months after surgery, patient satisfaction (willingness to undergo the same procedure again) was obtained. Complications, blood loss, and length of stay (LOS) were abstracted from the clinical notes and the electronic patient files. Patients improved significantly on all domains of HRQOL (16.0%-59.7%) and physical functioning (14.7%-15.8%) 3 months after surgery in comparison with preoperatively. No improvement was reported on HRQOL and physical functioning, except the Timed Up and Go score (14.1%), at 12 months after surgery in comparison with 3 months. No major or minor complications were found, and LOS was 2.9 days on average. One year after the surgery, all patients expressed satisfaction as suggested by their willingness to undergo the same surgical procedure again. Our study demonstrates that SSBHR offers a rapid recovery time and significant improvements in both functional status and HRQOL within 3 months after surgery. These findings can inform healthcare professionals and patients, suggesting that SSBHR is a viable treatment option for patients with bilateral hip osteoarthritis. Further research, including multicenter randomized controlled trials, is recommended to compare the recovery outcomes of SSBHR with two-stage bilateral hip replacement and confirm our findings

Age-Associated Changes in Proximal Femur Morphology Affect Femoral Component Sizing in Cementless Hip Arthroplasty

BACKGROUND: In cementless hip arthroplasty, the femoral component should obtain firm fixation within the endosteal bone and achieve adequate reconstruction of hip joint biomechanics simultaneously. Previous anatomical studies described age-related changes of the proximal femoral canal, such as canal widening, which theoretically necessitates the use of larger stem sizes in elderly patients. This study examines a potential association between patients' age at surgery and the implant size of a cementless femoral component. MATERIAL AND METHODS: A total of 13,423 primary hip arthroplasties with a single cementless stem registered in the Dutch Arthroplasty Register (LROI) were included. Patient characteristics (ie patients' age, sex, height and weight at time of surgery) and femoral component size were derived. A one-way ANCOVA was used to compare the mean stem size between age groups, and multivariable linear regression analysis was used in order to investigate to which extent ageing impacted stem size. RESULTS: Each subsequent age- group (ten-year intervals) had a significantly larger mean stem size than the prior age- group. Multivariable linear regression analysis revealed that age is positively correlated with stem size and that this correlation is more prominent in females than in males (beta = .046, P < .001 and beta = .028, P < .001 respectively). INTERPRETATION: Implant size is positively correlated with age, in particular in females and independently from investigated anthropometric characteristics. The present study endorses that the femoral canal morphology is related to patients' characteristics such as age and sex. The morphology will subsequently influence implant sizing and therefore may have biomechanical and clinical implications

Femoral Head Size is Correlated With Head Position in Very Elderly Patients

Background: In cases of femoral neck fracture, it is often not possible to accurately determine the original position of the head center to assess appropriate restoration of leg length. The aim of this study was to determine the accuracy of predicting the position of the femoral head center based on new and established correlations between the femoral head diameter (FHD) and the distance between the lesser trochanter and the femoral head center (LT-FHC) in the very elderly (aged >= 80 years) as the mainly affected but yet underinvestigated group. Methods: The FHD and the LT-FHC distance were determined in 148 subjects (104 males, 44 females); 90 aged >= 80 years and 58 aged Results: The FHD and the LT-FHC were significantly correlated, most strongly in elderly females (R = 0.554, P <.001). Using the new age-and gender-specific ratios, the LT-FHC distance could be predicted within 10 mm of the true value in 95% of the cases and in only 77% using previously reported formulas. Conclusion: Age-and gender-specific formulas yield higher accuracy than generic formulas. The formulas presented in this study can offer a practical, easy to use instrument for orthopedic surgeons performing hip arthroplasty in very elderly patients in addition to classic techniques to prevent significant leg-length discrepancy.

Twenty-Two-Year Outcome of Cartilage Repair Surgery by Perichondrium Transplantation

OBJECTIVE: The main purpose of the present study was to assess the risk for major revision surgery after perichondrium transplantation (PT) at a minimum of 22 years postoperatively and to evaluate the influence of patient characteristics. DESIGN: Primary outcome was treatment success or failure. Failure of PT was defined as revision surgery in which the transplant was removed, such as (unicondylar) knee arthroplasty or patellectomy. The functioning of nonfailed patients was evaluated using the International Knee Documentation Committee (IKDC) score. In addition, the influence of patient characteristics was evaluated. RESULTS: Ninety knees in 88 patients, aged 16 to 55 years with symptomatic cartilage defects, were treated by PT. Eighty knees in 78 patients were eligible for analysis and 10 patients were lost to follow-up. Twenty-eight knees in 26 patients had undergone major revision surgery. Previous surgery and a longer time of symptoms prior to PT were significantly associated with an increased risk for failure of cartilage repair. Functioning of the remaining 52 patients and influence of patient characteristics was analyzed using their IKDC score. Their median IKDC score was 39.08, but a relatively young age at transplantation was associated with a higher IKDC score. CONCLUSIONS: This 22-year follow-up study of PT, with objective outcome parameters next to patient-reported outcome measurements in a unique group of patients, shows that overall 66% was without major revision surgery and patient characteristics also influence long-term outcome of cartilage repair surgery

Referral decisions and its predictors related to orthopaedic care. A retrospective study in a novel primary care setting

Due to the ageing population, the prevalence of musculoskeletal disorders will continue to rise, as well as healthcare expenditure. To overcome these increasing expenditures, integration of orthopaedic care should be stimulated. The Primary Care Plus (PC+) intervention aimed to achieve this by facilitating collaboration between primary care and the hospital, in which specialised medical care is shifted to a primary care setting. The present study aims to evaluate the referral decision following orthopaedic care in PC+ and in particular to evaluate the influence of diagnostic tests on this decision. Therefore, retrospective monitoring data of patients visiting PC+ for orthopaedic care was used. Data was divided into two periods; P1 and P2. During P2, specialists in PC+ were able to request additional diagnostic tests (such as ultrasounds and MRIs). A total of 2,438 patients visiting PC+ for orthopaedic care were included in the analysis. The primary outcome was the referral decision following PC+ (back to the general practitioner (GP) or referral to outpatient hospital care). Independent variables were consultation- and patient-related predictors. To describe variations in the referral decision, logistic regression modelling was used. Results show that during P2, significantly more patients were referred back to their GP. Moreover, the multivariable analysis show a significant effect of patient age on the referral decision (OR 0.86, 95% CI = 0.81-0.91) and a significant interaction was found between the treating specialist and the period (p = 0.015) and between patient's diagnosis and the period (p ≤ 0.001). Despite the significant impact of the possibility of requesting additional diagnostic tests in PC+, it is important to discuss the extent to which the availability of diagnostic tests fits within the vision of PC+. In addition, selecting appropriate profiles for specialists and patients for PC+ are necessary to further optimise the effectiveness and cost of care
