Late-stage rehabilitation after anterior cruciate ligament reconstruction: A multicentre randomised controlled trial (PReP)

BACKGROUND

At the completion of formal rehabilitation after anterior cruciate ligament reconstruction, functional capacity is only restored in a small proportion of affected individuals. Therefore, the end of formal rehabilitation is not the end of functional rehabilitation.

OBJECTIVE

To compare adherence to and effectiveness of a late-stage rehabilitation programme with usual care after anterior cruciate ligament (ACL) reconstruction.

METHODS

This prospective, double-blind, multicentre, parallel group, randomised controlled trial, included people aged 18 to 35 years after formal rehabilitation completion (mean [SD] 241 [92] days post-reconstruction). Participants were block-randomised to a 5-month neuromuscular performance intervention (Stop-X group) or usual care (medically prescribed standard physiotherapy, individual formal rehabilitation, home-exercises). All outcomes were measured once/month. Primary outcome was the normalised knee separation distance on landing after drop jump. Baseline-adjusted linear mixed models were calculated.

RESULTS

In total, 112 participants (Stop-X: 57; Usual care: 55,) were analysed. Initially, mean (SD) intervention frequency (units/week) was higher in the Stop-X than the Usual care group: 2.65 (0.96) versus 2.48 (1.14) units/week in the first and 2.28 (1.02) versus 2.14 (1.31) units/week in the second month. No between-group*time(*baseline)-differences were found for the primary outcome. Between-group*time-effects favoured the Stop-X-group at 2 months (fewer self-reported knee problems during sport, KOOS-SPORT) (estimate = 64.3, 95 % CI 24.4-104.3 for the Stop-X), more confidence to return to sport (ACL-RSI) (62.4, 10.7-114.2), fewer pain-associated knee problems (KOOS-PAIN) (82.8, 36.0-129.6), improved everyday activity abilities (KOOS-ADL) (71.1, 6.4-135.7), and improved limb symmetry index in the front hop for distance at 3 and 4 months (0.34, 0.10-0.57; 0.31, 0.08-0.54). No between-group*time-effects occurred for kinesiophobia, symptom-associated knee problems or balance hops performance. At the end of the intervention, 79 % of the Stop-X and 70 % of the Usual care participants (p < 0.05) had successfully returned to their pre-injury sport type and level.

CONCLUSIONS

The Stop-X intervention was slightly superior to usual care as part of late-stage rehabilitation after ACL-reconstruction. The small benefit might justify its use after formal rehabilitation completion.

The End of the Formal Rehabilitation Is Not the End of Rehabilitation: Knee Function Deficits Remain After Anterior Cruciate Ligament Reconstruction

OBJECTIVE

To rate athletes' functional ability and return to sport (RTS) success at the end of their individual, formal, medically prescribed rehabilitation after anterior anterior cruciate ligament (ACL) reconstruction.

METHODS

In our prospective multicenter cohort study, 88 (42 females) adults aged 18-35 years after acute unilateral ACL rupture and subsequent hamstring grafting were included. All patients were prospectively monitored during their rehabilitation and RTS process until the end of their formal rehabilitation and RTS release. As outcome measures, functional hop and jump tests (front hop, balance hops, and drop jump screening test) and self-report outcomes (Knee Injury and Osteoarthritis Outcome Score, ACL-RTS after injury) were assessed. Literature-based cut-off values were selected to rate each performance as fulfilled or not.

RESULTS

At 7.5 months (SD 2.3 months) after surgery, the percentage of participants meeting the functional thresholds ranged from 4% (Knee Injury and Osteoarthritis Outcome Score SPORT) and over 44% (ACL-RTS after injury sum score) to 59% (Knee Injury and Osteoarthritis Outcome Score activities of all daily living) in the self-report and from 29% (Balance side hop) to 69% (normalized knee separation distance) in performance testing. Only 4% fulfilled all the cut-offs, while 45% returned to the same type and level of sport. Participants who successfully returned to their previous sport (type and level) were more likely to be "over-cut-off-performers."

CONCLUSIONS

The low share of the athletes who fulfilled the functional RTS criteria highlights the importance of continuing the rehabilitation measures after the formal completion to assess the need for and success of, inter alia, secondary-preventive therapies.

EFAS/EAN survey on the influence of the COVID-19 pandemic on European clinical autonomic education and research

PURPOSE

To understand the influence of the coronavirus disease 2019 (COVID-19) pandemic on clinical autonomic education and research in Europe.

METHODS

We invited 84 European autonomic centers to complete an online survey, recorded the pre-pandemic-to-pandemic percentage of junior participants in the annual congresses of the European Federation of Autonomic Societies (EFAS) and European Academy of Neurology (EAN) and the pre-pandemic-to-pandemic number of PubMed publications on neurological disorders.

RESULTS

Forty-six centers answered the survey (55%). Twenty-nine centers were involved in clinical autonomic education and experienced pandemic-related didactic interruptions for 9 (5; 9) months. Ninety percent (n = 26/29) of autonomic educational centers reported a negative impact of the COVID-19 pandemic on education quality, and 93% (n = 27/29) established e-learning models. Both the 2020 joint EAN-EFAS virtual congress and the 2021 (virtual) and 2022 (hybrid) EFAS and EAN congresses marked higher percentages of junior participants than in 2019. Forty-one respondents (89%) were autonomic researchers, and 29 of them reported pandemic-related trial interruptions for 5 (2; 9) months. Since the pandemic begin, almost half of the respondents had less time for scientific writing. Likewise, the number of PubMed publications on autonomic topics showed the smallest increase compared with other neurological fields in 2020-2021 and the highest drop in 2022. Autonomic research centers that amended their trial protocols for telemedicine (38%, n = 16/41) maintained higher clinical caseloads during the first pandemic year.

CONCLUSIONS

The COVID-19 pandemic had a substantial negative impact on European clinical autonomic education and research. At the same time, it promoted digitalization, favoring more equitable access to autonomic education and improved trial design.

Contributors to self-report motor function after anterior cruciate ligament reconstruction

Numerous functional factors may interactively contribute to the course of self-report functional abilities after anterior cruciate ligament  (ACL)-reconstruction. This study purposes to identify these predictors using exploratory moderation-mediation models in a cohort study design. Adults with post unilateral ACL reconstruction (hamstring graft) status and who were aiming to return to their pre-injury type and level of sport were included. Our dependent variables were self-reported function, as assessed by the the KOOS subscales sport (SPORT), and activities of daily living (ADL). The independent variables assessed were the KOOS subscale pain and the time since reconstruction [days]. All other variables (sociodemographic, injury-, surgery-, rehabilitation-specific, kinesiophobia (Tampa Scale of Kinesiophobia), and the presence or absence of COVID-19-associated restrictions) were further considered as moderators, mediators, or co-variates. Data from 203 participants (mean 26 years, SD 5 years) were finally modelled. Total variance explanation was 59% (KOOS-SPORT) and 47% (KOOS-ADL). In the initial rehabilitation phase (< 2 weeks after reconstruction), pain was the strongest contributor to self-report function (KOOS-SPORT: coefficient: 0.89; 95%-confidence-interval: 0.51 to 1.2 / KOOS-ADL: 1.1; 0.95 to 1.3). In the early phase (2-6 weeks after reconstruction), time since reconstruction [days] was the major contributor (KOOS-SPORT: 1.1; 0.14 to 2.1 / KOOS-ADL: 1.2; 0.43 to 2.0). Starting with the mid-phases of the rehabilitation, self-report function was no longer explicitly impacted by one or more contributors. The amount of rehabilitation [minutes] is affected by COVID-19-associated restrictions (pre-versus-post: - 672; - 1264 to - 80 for SPORT / - 633; - 1222 to - 45 for ADL) and by the pre-injury activity scale (280; 103 to 455 / 264; 90 to 438). Other hypothesised contributors such as sex/gender or age were not found to mediate the time or pain, rehabilitation dose and self-report function triangle. When self-report function is rated after an ACL reconstruction, the rehabilitation phases (early, mid, late), the potentially COVID-19-associated rehabilitation limitations, and pain intensity should also be considered. As, for example, pain is the strongest contributor to function in the early rehabilitation phase, focussing on the value of the self-report function only may, consequently, not be sufficient to rate bias-free function.

THE COVID-19 PANDEMIC DID NOT AFFECT REHABILITATION FOLLOWING ACL RECONSTRUCTION

ABSTRACT Objective: To assess postoperative rehabilitation patterns in patients who underwent Anterior Cruciate Ligament Reconstruction (ACLR) during the COVID-19 pandemic. Methods: A retrospective study of patients who underwent primary isolated ACLR between February 2019 and July 2020. Two different periods were evaluated. The “COVID group” represents the period from February 1st to July 1st of 2020 and the “non-COVID group” represents the equivalent period in 2019. Rehabilitation features and the effect of the COVID-19 pandemic on rehabilitation habits were assessed. Patient outcome scores were assessed using the Lysholm, Tegner, and International Knee Documentation Committee (IKDC) questionnaires. Subjective satisfaction, post-operative complications, and subsequent surgeries were recorded. Results: The groups did not differ significantly in demographics, functional outcome scores, or subjective satisfaction. There was no significant difference in rehabilitation patterns between the groups. In the COVID group, only one patient (4%) reported participation in online physiotherapy. Conclusions: There were no differences in the post-operative rehabilitation patterns, including duration, length, and environment of the training, between patients who underwent primary isolated ACLR during the COVID-19 pandemic and those who underwent the treatment in the preceding non-COVID year. Patient outcome scores, subjective satisfaction, and subsequent surgery rates did not differ between the groups. Level of evidence IV; Therapeutic studies - investigation of treatment results.

The German Arthroscopy Registry DART: what has happened after 5 years?

PURPOSE

The German Arthroscopy Registry (DART) has been initiated in 2017 with the aim to collect real-life data of patients undergoing knee, shoulder, hip or ankle surgery. The purpose of this study was to present an overview of the current status and the collected data thus far.

METHODS

Data entered between 11/2017 and 01/2022 were analyzed. The number of cases (each case is defined as a single operation with or without concomitant procedures) entered for each joint, follow-up rates and trends between different age groups (18-29 years, 30-44 years, 45-64 years,  ≥ 65 years) and across genders, and quality of life improvement (pre- vs. 1 year postoperative EQ visual analogue scale [EQ-VAS]) for frequently performed procedures (medial meniscus repair [MMR] vs. rotator cuff repair [RCR] vs. microfracturing of the talus [MFX-T]) were investigated.

RESULTS

Overall, 6651 cases were entered into DART, forming three distinct modules classified by joint (5370 knee, 1053 shoulder and 228 ankle cases). The most commonly entered procedures were: knee: partial medial meniscectomy (n = 2089), chondroplasty (n = 1389), anterior cruicate ligament reconstruction with hamstring autograft (n = 880); shoulder: sub acromial decompression (n = 631), bursectomy (n = 385), RCR (n = 359); ankle: partial synovectomy (n = 117), tibial osteophyte resection (n = 72), loose body removal (n = 48). In the knee and shoulder modules, middle-aged patients were the predominant age group, whereas in the ankle module, the youngest age group was the most frequent one. The two oldest age groups had the highest 1-year follow-up rates across all modules. In the knee and shoulder module, 1-year follow-up rates were higher in female patients, whereas follow-up rates were higher in male patients in the ankle module. From pre- to 1-year postoperative, MFX-T (EQ-VAS: 50.0 [25-75% interquartile range: 31.8-71.5] to 75.0 [54.3-84.3]; ∆ + 25.0) led to a comparably larger improvement in quality of life than did MMR (EQ-VAS: 70.0 [50.0-80.0] to 85.0 [70.0-94.0]; ∆ + 15.0) or RCR (EQ-VAS: 67.0 [50.0-80.0] to 85.0 [70.0-95.0]; ∆ + 18.0).

CONCLUSION

DART has been sufficiently established and collects high-quality patient-related data with satisfactory follow-up allowing for a comprehensive analysis of the collected data. The current focus lies on improving patient enrolment and follow-up rates as well as initiating the hip module.

Investigation of the Clinical Effect of New Shoulder Joint Abduction Frame in Humeral Fracture Patients after Arthroscopic Shoulder Surgery

Objective

This work is organized to analyze the clinical effects of new shoulder joint abduction frame on the bone metabolic markers, shoulder joint function, and visual analogue scale (VAS) of humeral fracture patients undergoing arthroscopic surgery.

Methods

118 patients with humeral fracture who planned to undergo shoulder surgery in our hospital from November 2018 to June 2021 were selected as the study objects and were divided into two groups according to the random number method, with 59 patients in each group. The patients in the two groups were subjected to arthroscopic shoulder surgery. New shoulder joint abduction frame was used for shoulder joint fixation in the abduction frame group, and sling was used for shoulder joint fixation in the sling group after surgery. The duration of fixation was 4-6 weeks. Finally, the prognostic indicators, complications, and serum bone metabolism levels in 4 and 6 weeks after surgery, shoulder joint function (Neer score), VAS score before surgery and after 3 and 6 months of surgery, and excellent or good rate of shoulder joint activity after 6 months of surgery were compared between the two groups.

Results

The postoperative fracture healing time and start time of shoulder joint training were shorter, and the humeral varus angle and femur height loss were smaller in the abduction frame group than in the sling group (P < 0.05). There was no significant difference in the total incidence of complications between the two groups (3.39% and 13.56%, respectively) (P > 0.05). After 4 or 6 weeks of surgery, the levels of serum osteoprotegerin (OPG) and carboxyterminal propeptide of type I procollagen (PICP) were increased but the levels of tartrate-resistant acid phosphatase-5B (TRAP-5B) were decreased in the two groups with more significant differences in the abduction frame group (P < 0.05). After 6 months of follow-up, 2 cases were lost to follow-up in the abduction frame group and 3 cases in the sling group. Neer scores were increased, while VAS scores were decreased in the two groups in the third or sixth months after surgery with significant differences in the abduction frame group (P < 0.05). The excellent or good rate of shoulder joint activity was 94.74% (54/57) in the abduction frame group, significantly higher than that in the sling group (80.36%; 45/56) (P < 0.05).

Conclusion

The fixation effect of new shoulder joint abduction frame is significant after arthroscopic surgery, and patients can carry out functional training as early as possible, which is helpful to promote fracture healing, relieve pain, and restore shoulder joint function with high safety.

Impact of the COVID-19 Pandemic on Elective and Emergency Inpatient Procedure Volumes in Switzerland - A Retrospective Study Based on Insurance Claims Data

BACKGROUND

The severe acute respiratory syndrome coronavirus 2 (SARS‑CoV‑2) pandemic forced hospitals to redistribute resources for the treatment of patients with coronavirus disease 2019 (COVID-19), yet the impact on elective and emergency inpatient procedure volumes is unclear.

METHODS

We analyzed anonymized data on 234 921 hospitalizations in 2017-2020 (55.9% elective) from a big Swiss health insurer. We used linear regression models to predict, based on pre-pandemic data, the expected weekly numbers of procedures in 2020 in the absence of a pandemic and compared these to the observed numbers in 2020. Compensation effects were investigated by discretely integrating the difference between the two numbers over time.

RESULTS

During the first COVID-19 wave in spring 2020, elective procedure numbers decreased by 52.9% (95% confidence interval -64.5% to -42.5%), with cardiovascular and orthopedic elective procedure numbers specifically decreasing by 45.5% and 72.4%. Elective procedure numbers normalized during summer with some compensation of postponed procedures, leaving a deficit of -9.9% (-15.8% to -4.5%) for the whole year 2020. Emergency procedure numbers also decreased by 17.1% (-23.7% to -9.8%) during the first wave, but over the whole year 2020, net emergency procedure volumes were similar to control years.

CONCLUSION

Inpatient procedure volumes in Switzerland decreased considerably in the beginning of the pandemic but recovered quickly after the first wave. Still, there was a net deficit in procedures at the end of the year. Health system leaders must work to ensure that adequate access to non-COVID-19 related care is maintained during future pandemic phases in order to prevent negative health consequences.

The effect of COVID-19 on children with congenital talipes equinovarus in a tertiary service in the United Kingdom

During the coronavirus disease 2019 (COVID-19) pandemic, many aspects of healthcare have been hindered. The primary aim of this study was to identify what the impact of COVID-19 was on the delivery of outpatient care for children with congenital talipes equinovarus deformity (CTEV) at a large tertiary hospital in the UK. This study reviewed the patients who commenced their Ponseti treatment between March and September 2020, representing the cohort who received hands-on care during the first wave of the COVID-19 pandemic. Equivalent 6-month periods were searched in 2019 and 2018 as control cohorts. This study included a total of 45 children (72 affected feet) presenting for treatment of clubfoot. Twenty-three babies were seen with CTEV in 2020. For the same time period in 2018 and 2019, 11 babies were treated each year. The distance commuted to by families was higher in 2020 compared to 2019 and 2018, although the difference did not reach statistical significance (P = 0.301). Treatment with Ponseti casting was commenced at a mean age of 52 days, with no statistically significant differences between cohorts (P = 0.758). Using strict precautions, the Ponseti service at a large tertiary hospital in the UK grew in size and successfully provided treatment for children presenting with CTEV during the first wave of the COVID-19 pandemic. This study has shown that with careful protocols in place, children with CTEV can be treated successfully during times of pandemic, thereby reducing the post-pandemic burden of older children requiring treatment.

Effects of the COVID-19 Pandemic on the Epidemiology of Knee and Shoulder Arthroscopy

The purpose of our study was to comprehensively assess the effect of the COVID-19 pandemic on knee and shoulder arthroscopy performed in an orthopedic department of a university hospital in Poland. This study compared the data on all shoulder and knee arthroscopy procedures performed in two different periods: The period of the COVID-19 pandemic in Poland (from March 4, 2020, to October 15, 2020) and the corresponding period prior to the pandemic (March 4, 2019, to October 15, 2019). The study evaluated epidemiological data, demographic data, and hospital stay duration. The total number of arthroscopy procedures conducted in the evaluated period in 2020 was approximately 8.6% higher than that in the corresponding 2019 period. The mean duration of hospital stay for orthopedic patients after their knee or shoulder arthroscopy was 3.1 days in 2020 and 2.8 days in 2019. Our study revealed the mean age of arthroscopy patients during the pandemic to be lower at 48.4 years than the 51.2 years recorded in 2019. The male-to-female ratio was shown to be lower at .85 during the pandemic, having decreased from 1.5 in 2019. The COVID-19 pandemic did not reduce the number of arthroscopy performed at our center, and the mean age of the patients did not change. However, the pandemic had a marked effect on the mean duration of hospital stay and male-to-female ratio.

Management of Outpatient Elective Surgery for Arthroplasty and Sports Medicine During the COVID-19 Pandemic: A Scoping Review

Background:

The onset of the coronavirus disease 2019 (COVID-19) pandemic has presented unforeseeable challenges to the orthopaedic community, especially arthroplasty and sports medicine subspecialities, as many surgeries were deemed nonessential and delayed. Although there is a glimpse of hope with the approval and distribution of vaccines, daily case numbers and death tolls continue to rise at the time of this review.

Purpose:

To summarize the available literature on the management of elective sports medicine and arthroplasty procedures in the outpatient setting to gather a consolidated source of information.

Study Design:

Scoping review; Level of evidence, 5.

Methods:

A scoping review of 3 databases (PubMed, Embase, and OVID Medline) was performed using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) checklist. All retrospective and prospective analyses, systematic reviews and meta-analyses, expert opinions, and societal guidelines were included for review, with 29 articles meeting the inclusion criteria.

Results:

Guidance for resumption of elective arthroplasty and sports medicine surgery and patient selection during the COVID-19 pandemic focuses on resource availability, patient fitness, and time sensitivity of the procedure, with patient and surgical team safety as the highest priority. Telemedicine and other innovative technology can be used to continue patient care during periods of delayed surgery through monitoring disease progression and offering nonoperative management options.

Conclusion:

While the current societal recommendations provide guidance on safety protocols and patient prioritization, each orthopaedic practice must consider its unique situation and use evidence-based medicine when determining surgical timing and patient selection.

The Epidemiology of Hip and Knee Primary and Revision Arthroplasties during the COVID-19 Pandemic

BACKGROUND

The purpose of this study was to provide a comprehensive assessment of the impact of the COVID-19 pandemic on the epidemiology of primary and revision arthroplasties of the hip and knee joint.

METHODS

This study compared the data on knee and hip arthroplasty procedures from 2 hospitals (primary and revision) conducted in two periods: the period of the COVID-19 pandemic in Poland (from 4 March 2020 to 15 October 2020) and the corresponding period prior to the pandemic (from 4 March 2019 to 15 October 2019). We compared the epidemiological data, demographic data, and hospital stay duration data from these two periods.

RESULTS

Our analysis demonstrated that the total number of hip arthroplasties conducted in 2020 decreased by 26% in comparison with 2019. In the case of knee arthroplasties, the total number of procedures in the evaluated period in 2020 decreased by 44%. Our study also showed that the mean time of hospital stay for orthopedic patients following hip or knee arthroplasty was 22.87% shorter. The female-to-male patient ratio decreased between the analyzed periods, and this was 22.96% lower during the pandemic.

CONCLUSION

The COVID-19 pandemic in these two hospitals in Poland led to reduced numbers of hip and knee replacement procedures, shorter hospital stays, and a decreased female-to-male patient ratio. The mean age of patients undergoing hip or knee arthroplasty remained unchanged during the national lockdown with respect to the pre-pandemic figure.

The long road to recovery: at six months since the first COVID-19 wave, elective orthopedic care has still not fully recovered in Belgium

PURPOSE

The primary aim of our study was to investigate elective orthopaedic care during the first wave government-imposed COVID-19 lockdown and at four weeks and 21 weeks after resuming elective care. The secondary aim of our study was to evaluate the implementation of the European Society of Sports Traumatology, Knee Surgery and Arthroscopy (ESSKA) COVID-19 Guidelines and Recommendations for Resuming Elective Surgery in the clinical practice of Belgian knee surgeons.

METHODS

We sent three anonymous online surveys to 102 Belgian Knee Society members (BKS) at times mentioned above. Addressed topics were: (1) participant demographics, (2) elective surgeries, (3) outpatient visits, (4) ESSKA Guidelines, (5) patient and surgeon safety.

RESULTS

During the COVID-19 lockdown, there was a decrease of 97% in elective knee surgeries and 91% in outpatient visits. At four and 21 weeks after resuming elective care, volumes were respectively 67% and 89% for elective surgeries and 81% and 91% for outpatient visits. Regarding ESSKA guidelines, 91% of surgeons had no COVID-19 testing prior to resuming elective care. Ninety-two per cent reported preoperative (< 72 h) patient PCR testing, and 45% gave preference to young patients without comorbidities. Seventy-two per cent did not use additional personal protective equipment (PPE) if a patient PCR test was negative. Forty-nine per cent continued to give preference to general anaesthesia.

CONCLUSION

Our study shows that elective surgeries and outpatient visits were almost completely interrupted during the COVID-19 lockdown and were still below normal at four and 21 weeks after resuming elective care. Regarding ESSKA COVID-19 guidelines, our study observes good compliance in preoperative patient COVID-19 testing, but lower compliance for preoperative health care personnel testing, patient selection, use of PPE, and locoregional anaesthesia.
