RESUMO
BACKGROUND AND PURPOSE: This study's purpose was to investigate the reliability, validity, and responsiveness of the Patient-Specific Functional Scale (PSFS) for measuring mobility-related goals in people with multiple sclerosis (MS). METHODS: Data from 32 participants with MS who underwent 8 to 10 weeks of rehabilitation were analyzed (Expanded Disability Status Scale scores 1.0-7.0). For the PSFS, participants identified 3 mobility-related areas where they had difficulty and rated them at baseline, 10 to 14 days later (before starting intervention), and immediately after intervention. Test-retest reliability and response stability of the PSFS were calculated using the intraclass correlation coefficient (ICC 2,1 ) and minimal detectable change (MDC 95 ), respectively. Concurrent validity of the PSFS was determined with the 12-item Multiple Sclerosis Walking Scale (MSWS-12) and the Timed 25-Foot Walk Test (T25FW). PSFS responsiveness was determined using Cohen's d , and minimal clinically important difference (MCID) was calculated based on patient-reported improvements on a Global Rating of Change (GRoC) scale. RESULTS: The PSFS total score demonstrated moderate reliability (ICC 2,1 = 0.70, 95% CI: 0.46 to 0.84) and the MDC was 2.1 points. At baseline, the PSFS was fairly and significantly correlated with the MSWS-12 ( r = -0.46, P = 0.008) but not with the T25FW. Changes in the PSFS were moderately and significantly correlated with the GRoC scale (ρ = 0.63, P < 0.001), but not with MSWS-12 or T25FW changes. The PSFS was responsive ( d = 1.7), and the MCID was 2.5 points or more to identify patient-perceived improvements based on the GRoC scale (sensitivity = 0.85, specificity = 0.76). DISCUSSION AND CONCLUSIONS: This study supports the use of the PSFS as an outcome measure in people with MS to assess mobility-related goals.Video Abstract available for more insights from the authors (see the Video, Supplemental Digital Content 1, available at: http://links.lww.com/JNPT/A423 ).

[Purpose] There is little evidence for blood flow restriction (BFR), or Kaatsu, training in people with neurologic conditions. This study's purpose was to survey clinicians on BFR use in people with neurologic conditions. [Participants and Methods] One-hundred twelve physical therapists and other healthcare professionals who reported using BFR in the past 5â years completed an anonymous, online survey. [Results] Eighty-nine percent of respondents thought BFR was safe in people with neurologic conditions. Meanwhile, 38% reported BFR use in people with neurologic conditions. The most common intervention used with BFR was resistance training (n=33) and the most commonly reported benefit was improved strength (n=27). The most common side-effect causing treatment to stop was intolerance to pressure (n=6). No side-effects requiring medical attention were reported. In order to support future BFR use in neurologic populations, the most common response was the need for more research (n=63). [Conclusion] Despite the lack of evidence, clinical use of BFR in people with neurologic conditions may be somewhat common. Although this study had a relatively small sample size and collected data retrospectively, the results support the potential clinical feasibility and safety of BFR use in patients with neurologic conditions and suggest that more research is needed.
RESUMO
BACKGROUND: With recent Medicare payment changes, older adults are increasingly likely to be discharged home instead of to extended care facilities after total joint arthroplasty (TJA), and may therefore be at increased risk for readmissions. Identifying risk factors for readmission could help re-align care pathways for vulnerable patients; recent research has suggested preoperative dependency in activities of daily living (ADL) may increase perioperative and postoperative surgical complications. However, the proportion of older surgical patients with ADL dependence before TJA, and the impact of ADL dependency on the frequency and timing of hospital readmissions is unknown. QUESTIONS/PURPOSES: (1) What proportion of older adults discharged home after TJA have preoperative ADL dependency? (2) Is preoperative ADL dependency associated with increased risk of hospital readmissions at 30 days or 90 days for older adults discharged home after TJA? METHODS: This was a retrospective cohort analysis of 6270 Medicare fee-for-service claims from 2012 from a 5% national Medicare sample for older adults (older than 65 years) receiving home health care after being discharged to the community after elective TJA. Medicare home health claims were used for two reasons: (1) the primary population of interest was older adults and (2) the accompanying patient-level assessment data included an assessment of prior dependency on four ADL tasks. Activities of daily living dependency was dichotomized as severe (requiring human assistance with all four assessed tasks) or partial/none (needing assistance with three or fewer ADLs); this cutoff has been used in prior research to evaluate readmission risk. Multivariable logistic regression models, clustered at the hospital level and adjusted for known readmission risk factors (such as comorbidity status or age), were used to model the odds of 30- and 90- day and readmission for patients with severe ADL dependence. RESULTS: Overall, 411 patients were hospitalized during the study period. Of all readmissions, 64% (262 of 411) occurred within the first 30 days, with a median (interquartile range [IQR]) time to readmission of 17 days (5 to 46). Severe ADL dependency before surgery was common for older home health recipients recovering from TJA, affecting 17% (1066 of 6270) of our sample population. After adjusting for clinical covariates, severe ADL dependency was not associated with readmissions at 90 days (adjusted odds ratio = 1.20 [95% CI 0.93 to 1.55]; p = 0.15). However, severe preoperative ADL dependency was associated with higher odds of readmission at 30 days (adjusted OR = 1.45 [95% CI 1.11 to 1.99]; p = 0.008). CONCLUSIONS: Severe preoperative ADL dependency is modestly associated with early but not late hospital readmission after TJA. This work demonstrates that it may important to apply a simple screening of ADL dependency preoperatively so that surgeons can guide changes in care planning for older adults undergoing TJA, which may include participation in preoperative rehabilitation (pre-habilitation) or more aggressive follow-up in the 30 days after surgery. Further research is needed to determine whether severe ADL dependence can be modified before surgery, and whether these changes in dependency can reduce readmission risk after TJA. LEVEL OF EVIDENCE: Level III, therapeutic study.

OBJECTIVE: To determine the relation between performance on a clinical quadriceps activation battery with (1) activation measured by doublet interpolation and (2) recovery of quadriceps strength and functional performance after total knee arthroplasty (TKA). DESIGN: Planned secondary analysis of a randomized controlled trial. SETTING: University research laboratory. PARTICIPANTS: Patients (N=162; mean age, 63±7y; 89 women) undergoing TKA. MAIN OUTCOME MEASURES: Patients were classified as high (quadriceps activation battery ≥4/6) or low (quadriceps activation battery ≤3/6) based on performance on the quadriceps activation battery measured 4 days after TKA. Differences between groups in activation and recovery at 1, 2, 3, 6, and 12 months after TKA were compared using a repeated-measures maximum likelihood model. RESULTS: The low quadriceps activation battery group demonstrated poorer quadriceps activation via doublet interpolation (P=.01), greater quadriceps strength loss (P=.01), and greater functional performance decline (all P<.001) at 1 month after TKA compared with the high quadriceps activation battery group. Differences between low and high quadriceps activation battery groups on all measures did not persist at 3 and 12 months (all P>.05). CONCLUSIONS: Poor performance on the quadriceps activation battery early after TKA is related to poor quadriceps activation and poor recovery in the early postoperative period. Patients in the low quadriceps activation battery group took 3 months to recover to the same level as the high quadriceps activation battery group. The quadriceps activation battery may be useful in identifying individuals who need specific interventions to target activation deficits or different care pathways in the early postoperative period to speed recovery after TKA.

OBJECTIVES: The purpose of this study was to identify descriptive factors in individuals with a primary complaint of low back pain (LBP) associated with improved pain and function after receiving physical therapy for LBP with or without manual therapy and exercise directed at the femoroacetabular joints. METHODS: Participants were enrolled in a randomized clinical trial investigating physical therapy interventions for their LBP, with or without interventions directed at the femoroacetabular joints (hips). A participant was deemed recovered if all of the following were met: Numeric Pain Rating Scale (NPRS) score of ≤2 points, ≤10% on the modified Oswestry Disability Index at discharge, and a global rating of change score of +4 at both 2 weeks and discharge. Logistic regression modelling determined descriptor variables that best predicted treatment recovery. RESULTS: Data from 90 participants were included in the analysis, with 44% (n = 40) achieving recovery by discharge from physical therapy (average 7.95 [±4.68]) visits. The variables of concurrent hip problems, lower body mass index ≤25.4, an irritable condition, and a baseline NPRS score of 4 points or less were retained in the final model (R2 = .384). Having a concurrent hip problem had the highest odds of achieving recovery in the model (odds ratio: 5.34, 95 % confidence interval: 1.31-21.8). CONCLUSIONS: The findings for the patients in this study suggest that those with a concurrent hip problem, a lower body mass index, irritable symptoms, and a baseline NPRS score of 4 points or less were associated with greater odds of achieving recovery with multimodal physical therapy interventions. Further research should continue to investigate the interplay between the lumbar spine and hip joints.

BACKGROUND: Arthrofibrosis is a debilitating postoperative complication of total knee arthroplasty (TKA). It is one of the leading causes of hospital readmission and a predominant reason for TKA failure. The prevalence of arthrofibrosis will increase as the annual incidence of TKA in the United States rises into the millions. METHODS: In a narrative review of the literature, the etiology, economic burden, treatment strategies, and future research directions of arthrofibrosis after TKA are examined. RESULTS: Characterized by excessive proliferation of scar tissue during an impaired wound healing response, arthrofibrotic stiffness causes functional deficits in activities of daily living. Postoperative, supervised physiotherapy remains the first line of defense against the development of arthrofibrosis. Also, adjuncts to traditional physiotherapy such as splinting and augmented soft tissue mobilization can be beneficial. The effectiveness of rehabilitation on functional outcomes depends on the appropriate timing, intensity, and progression of the program, accounting for the patient's ability and level of pain. Invasive treatments such as manipulation under anesthesia, debridement, and revision arthroplasty improve range of motion, but can be traumatic and costly. Future studies investigating novel treatments, early diagnosis, and potential preoperative screening for risk of arthrofibrosis will help target those patients who will need additional attention and tailored rehabilitation to improve TKA outcomes. CONCLUSION: Arthrofibrosis is a multi-faceted complication of TKA, and is difficult to treat without an early, tailored, comprehensive rehabilitation program. Understanding the risk factors for its development and the benefits and shortcomings of various interventions are essential to best restore mobility and function.

OBJECTIVE: The objective of this study was to determine the feasibility of low-load resistance training with blood flow restriction (BFR) for people with advanced disability due to multiple sclerosis (MS). METHODS: In this prospective cohort study, 14 participants with MS (Expanded Disability Status Scale [EDSS] score = 6.0 to 7.0; mean age = 55.4 [SD = 6.2] years; 71% women) were asked to perform 3 lower extremity resistance exercises (leg press, calf press, and hip abduction) bilaterally twice weekly for 8 weeks using BFR. Feasibility criteria were as follows: enrollment of 20 participants, ≥80% retention and adherence, ≥90% satisfaction, and no serious adverse events related to the intervention. Other outcomes included knee extensor, ankle plantar flexor, and hip abductor muscle strength, 30-Second Sit-to-Stand Test, Berg Balance Scale, Timed 25-Foot Walk Test, 12-Item MS Walking Scale, Modified Fatigue Impact Scale, Patient-Specific Functional Scale, and daily step count. RESULTS: Sixteen participants consented, and 14 completed the intervention, with 93% adherence overall. All participants were satisfied with the intervention. A minor hip muscle strain was the only intervention-related adverse event. There were muscle strength improvements on the more-involved (16%-28%) and less-involved (12%-19%) sides. There were also changes in the 30-Second Sit-to-Stand Test (1.9 repetitions; 95% CI = 1.0 to 2.8), Berg Balance Scale (5.3 points; 95% CI = 3.2 to 7.4), Timed 25-Foot Walk Test (-3.3 seconds; 95% CI = -7.9 to 1.3), Modified Fatigue Impact Scale (-8.8 points; 95% CI = -16.5 to -1.1), 12-Item MS Walking Scale (-3.6 points; 95% CI = -11.5 to 4.4), Patient-Specific Functional Scale (2.9 points; 95% CI = 1.9 to 3.8), and daily step count (333 steps; 95% CI = -191 to 857). CONCLUSION: Low-load resistance training using BFR in people with MS and EDSS scores of 6.0 to 7.0 appears feasible, and subsequent investigation into its efficacy is warranted. IMPACT: Although efficacy data are needed, combining BFR with low-load resistance training may be a viable alternative for people who have MS and who do not tolerate conventional moderate- to high-intensity training because of more severe symptoms, such as fatigue and weakness. LAY SUMMARY: Low-load strength training with BFR was feasible in people who have advanced disability due to MS. Using BFR may provide an alternative for people with MS who do not tolerate higher intensity training due to more severe symptoms, such as fatigue and weakness.

Total knee arthroplasty (TKA) improves patient-reported function by alleviating joint pain, however the surgical trauma exacerbates already impaired muscle function, which leads to further muscle weakness and disability after surgery. This early postoperative strength loss indicates a massive neural inhibition and is primarily driven by a deficit in quadriceps muscle activation, a process known as arthrogenic muscle inhibition (AMI). To enhance acute recovery of quadriceps muscle function and long-term rehabilitation of individuals after TKA, AMI must be significantly reduced in the early post-operative period. The aim of this narrative review is to review and discuss previous efforts to mitigate AMI after TKA and to suggest new approaches and interventions for future efficacy evaluation. Several strategies have been explored to reduce the degree of post-operative quadriceps AMI and improve strength recovery after TKA by targeting post-operative swelling and inflammation or changing neural discharge. A challenge of this work is the ability to directly measure AMI and relevant contributing factors. For this review we focused on interventions that aimed to reduce post-operative swelling or improve knee extension strength or quadriceps muscle activation measured by twitch interpolation. For individuals undergoing TKA, the use of anti-inflammatory medications, tranexamic acid, cryotherapy, intra-articular drains, torniquets, and minimally invasive surgical techniques for TKA have limited benefit in attenuating quadriceps AMI early after surgery. However, interventions such as inelastic compression garments, voluntary muscle contractions, and neuro-muscular electrical stimulation show promise in mitigating or circumventing AMI and should continue to be refined and explored.
RESUMO
BACKGROUND: Despite growing interest in minimally invasive surgery (MIS) techniques for total knee arthroplasty (TKA), few randomized controlled trials have compared MIS and conventional TKA using a combination of functional performance, knee pain, knee range of motion (ROM), and surgical and radiographic outcomes. METHODS: A prospective, randomized investigation comparing early outcomes of TKA using conventional or MIS approaches (n = 44). Patients were assessed preoperatively, 48 hours, 4 and 12 weeks postoperatively by blinded evaluators. Outcome measures included timed-up-and-go, 100-ft walk, knee pain, passive knee ROM, Knee Society Score, blood loss, tourniquet time, hospital length of stay, surgical complications, and radiographic outcomes. RESULTS: No significant differences in functional performance, knee pain, knee ROM, surgical, or radiographic outcomes were observed between groups at 48 hours, 4 or 12 weeks postoperatively. CONCLUSION: While surgical and radiographic outcomes were not compromised with MIS surgery, there were also no improvements in pain, ROM, or functional performance with MIS TKA.

OBJECTIVE: There is no consensus for how to use rehabilitation visits after total knee arthroplasty (TKA). We sought to develop expert recommendations for outpatient rehabilitation visit usage after TKA. DESIGN: Delphi study. METHODS: First, we developed a broad list of preliminary visit usage recommendations, which were specific to patients' recovery status (ie, slow, typical, or fast recovery) and time since surgery. We then invited 49 TKA experts to participate on a Delphi panel. During round 1, we surveyed panelists regarding their level of agreement with each preliminary recommendation. We conducted additional Delphi rounds as needed to build consensus, which we defined using the RAND/UCLA method. We updated the survey each round based on panelist feedback and responses from the previous round. RESULTS: Thirty panelists agreed to participate, and 29 panelists completed 2 Delphi rounds. The panel reached consensus on recommendations related to visit frequency, visit timing, and the use of telerehabilitation. The panel recommended that outpatient rehabilitation should begin within 1 week after surgery at a frequency of 2 times per week for the first postoperative month regardless of recovery status. The panel recommended different visit frequencies depending on the patient's recovery status for postoperative months 2 to 3. The panel agreed that telerehabilitation can be recommended for most patients after TKA, but not for patients recovering slowly. CONCLUSION: We used the Delphi process to develop expert recommendations for the use of outpatient rehabilitation visits after TKA. We envision these recommendations could help patients decide how to use visits based on their own preferences. J Orthop Sports Phys Ther 2023;53(9):1-9.

OBJECTIVE: Rigorously trained physical therapy researchers are essential for the generation of knowledge that guides the profession. However, there is a current and projected dearth of physical therapy researchers capable of sustaining research programs in part due to perceived financial barriers associated with pursuit of a doctor of philosophy (PhD) degree, with and without postdoctoral training, following doctor of physical therapy (DPT) degree completion. This study aimed to evaluate the financial impact of PhD and postdoctoral training, including opportunity cost, years to break even, and long-term earnings. METHODS: Clinical and academic salaries were obtained via the 2016 APTA Median Income of Physical Therapist Summary Report and 2019 CAPTE Annual Accreditation Report. Salaries were adjusted to total compensation to account for benefits and compared over a 30-year period starting after DPT education. Total compensations were also adjusted to the present value, placing greater weight on early career earnings due to inflation and potential investments. RESULTS: Relative to work as a clinical physical therapist, 4 years of PhD training result in an earnings deficit of $264,854 rising to $357,065 after 2 years of additional postdoctoral training. These deficits do not persist as evidenced by a clinical physical therapist career earning $449,372 less than a nonmajority scholarship academic career (DPT to PhD to academia pathway) and $698,704 less than a majority scholarship academic career (DPT to PhD to postdoctoral training to academia pathway) over a 30-year period. Greater long-term earnings for PhD careers persist when adjusting to present value. CONCLUSIONS: Although there is an initial opportunity cost of PhD and postdoctoral training represented by a relative earnings deficit, advanced research training results in greater long-term earnings. IMPACT: The findings of this study allow physical therapists interested in pursuing PhD and postdoctoral training to be better informed about the associated financial ramifications.

PURPOSE OF REVIEW: Previous studies on rehabilitation following total knee arthroplasty (TKA) demonstrated limited efficacy in increasing long-term outcomes. More recently, several rehabilitation approaches have demonstrated greater efficacy for increasing long-term strength and functional performance outcomes following TKA. RECENT FINDINGS: Neuromuscular electrical stimulation (NMES), applied to the surgical limb's quadriceps muscle for the first 6 weeks following surgery, has been shown to improve the speed of recovery from TKA and leads to long-term increases in strength and functional performance. Rehabilitation programs that incorporate higher intensity, progressive resistive exercises that target all major muscle groups of the lower extremity have demonstrated superior long-term strength and functional gains compared with lower intensity programs. Finally, although the greatest strength and functional losses occur immediately after surgery, there is emerging evidence that strength and functional gains can be made after the acute postoperative recovery period with programs focusing on the use of progressive aquatic exercise or eccentric exercise. SUMMARY: Functional recovery following TKA can be enhanced by the use of NMES and utilization of a comprehensive, higher intensity strength training program in conjunction with traditional rehabilitation approaches.

A prospective, randomized investigation compared early clinical outcomes of total knee arthroplasty (TKA) using conventional or minimally invasive surgical (MIS) approaches (n = 44). Outcome measures included isometric quadriceps and hamstrings strength, quadriceps activation, functional performance, knee pain, active knee range of motion, muscle mass, the Short Form-36, and Western Ontario and McMaster University Osteoarthritis Index, assessed preoperatively and 4 and 12 weeks after TKA. Four weeks after TKA, the MIS group had greater hamstring strength (P = .02) and quadriceps strength (P = .07), which did not translate to differences in other outcomes. At 12 weeks, there were no clinically meaningful differences between groups on any measure. Although MIS may lead to faster recovery of strength in patients undergoing TKA, there was no benefit on longer-term recovery of strength or functional performance.

RATIONALE: The benefits of clinical practice guideline (CPG) adoption for the management of patients with back pain are well documented. However, the gap between knowledge creation and implementation remains wide with few studies documenting the iterative process of comprehensive implementation in clinical settings. The objective of this study was to improve adherent physical therapy care according to CPG's for low back pain and describe the knowledge to action (K2A) process used in a rural healthcare organization. METHODS: A prospective case control cohort design was used to evaluate physical therapy provider practice changes during an 18 month intervention. Four clinical sites were selected, two of which received multifaceted educational and process interventions tailored to feedback from ongoing K2A cycle outcomes. Overall program assessment included monthly charge code reports for adherence and a pre-post survey of confidence for guideline use. Pragmatic Reach-Effectiveness-Adoption-Implementation-Maintenance (RE-AIM) criteria were used to complete the process evaluation. RESULTS: A significant difference (p < 0.001, mean difference 13.5, CI [8.5,18.5]) for charge code adherence favoured education site-1 over control site-2 after implementation. Adherence scores remained above target at both education sites 18 months after implementation. Survey differences were significant for confidence scores at education sites in use of the cognitive behavioural category, overall treatment category use and guideline communication. Process evaluation supported multifaceted interventions tailored to education sites with average cost measured by staff education time of 15.5 h per therapist trained. CONCLUSION: This study extends the literature of guideline implementation by describing the unique cycles required for promoting provider behaviour change within a rural healthcare system. Adherence and confidence results suggest increased provider CPG use which was supported by the process evaluation. This study demonstrates the importance of multiple site comparisons, long-term reporting and standardized frameworks for assessment of real-world CPG implementation.

OBJECTIVE: To determine the reliability, responsiveness, and convergent validity of the Four-Meter Walk Test (4mWT) compared to the Six-Minute Walk Test (6MWT) surrounding total knee arthroplasty (TKA). DESIGN: Secondary analysis of a randomized controlled trial. SETTING: Research laboratory. PARTICIPANTS: One hundred sixty-two patients (aged 63.5 ± 7.4 (mean ± sd) years; 89 females) undergoing TKA participated. MAIN OUTCOME MEASURES: 4mWT (usual and fastest) and 6MWT were measured 1-2 weeks preoperatively, and 1, 2, 3, 6 and 12 months post-operatively. RESULTS: 4mWT demonstrated excellent test-retest reliability with Interclass Correlation Coefficients (ICC's) ranging from 0.80 to 0.93 s. 4mWT also demonstrated small measurement error with Standard Error of Measurement (SEM) ranging from 0.15 to 0.35 s. 4mWT (fastest) demonstrated similar responsiveness to 6mWT in the first 2 months after surgery and better responsiveness from 2 to 3 months after surgery. Convergent validity between 6MWT and 4mWT (fastest) was high, with Pearson correlation coefficients ranging from 0.73 to 0.81. CONCLUSIONS: The 4mWT (fastest) has excellent test-retest reliability, shows high responsiveness sufficient for clinical outcomes in the immediate postoperative time periods, and exhibits high convergent validity with 6MWT. Given space and time requirements to conduct each test, 4mWT may be preferred for routine clinical assessment.IMPLICATIONS FOR REHABILITATIONWalking abilityâ¢Walking is an important functional ability for patients who undergo total knee arthroplasty (TKA).â¢While the Six-Minute Walk Test is a validated measure of walking ability in the TKA population, its clinical utility is limited by the space and time it takes to perform the test.â¢The Four-Meter Walk Test (fastest speed) is a valid, reliable, and responsive alternative to the 6MWT and is recommended for routine clinical use after TKA.

BACKGROUND: The ideal treatment of early-stage arthrofibrosis after total knee arthroplasty is unclear. The purpose of this study was to determine the treatment effect, including variability, and feasibility of a multimodal physical therapy program as compared to manipulation under anesthesia. METHODS: This was a prospective feasibility study with a retrospective cohort comparison. Ten consecutive patients (aged 64 ± 9 years, 7 females) with early-stage arthrofibrosis were enrolled 6 weeks after primary total knee arthroplasty and participated in the multimodal physical therapy program. The multimodal physical therapy program consisted of manual therapy, therapeutic exercise, and static progressive splinting delivered over 4 weeks. The outcomes included knee range of motion (ROM), adherence, patient satisfaction, and safety. Data were compared to a retrospective cohort of 31 patients with arthrofibrosis (aged 65 ± 9 years, 20 females) who underwent manipulation under anesthesia followed by physical therapy. RESULTS: Overall, knee ROM outcomes were similar between multimodal physical therapy (110° ± 14) and manipulation under anesthesia (109° ± 11). Seven out of ten patients achieved functional ROM (≥ 110°) and avoided manipulation under anesthesia with the multimodal physical therapy program. Three out of 10 multimodal physical therapy patients required manipulation under anesthesia secondary to failure to demonstrate progress within 4 weeks of the multimodal physical therapy program. Adherence to the multimodal physical therapy program was 87 ± 9%. The median patient satisfaction with the multimodal physical therapy program was "very satisfied." Safety concerns were minimal. CONCLUSION: The use of the multimodal physical therapy program is feasible for treating early-stage arthrofibrosis after total knee arthroplasty, with 70% of patients avoiding manipulation under anesthesia. Randomized controlled trials are needed to determine the efficacy of the multimodal physical therapy program and to determine the optimal patient selection for the multimodal physical therapy program versus manipulation under anesthesia. TRIAL REGISTRATION: ClinicalTrials.gov, NCT04837872 .
RESUMO
BACKGROUND: Swelling after total knee arthroplasty (TKA) is often profound and persistent, increasing risks of DVT, infection, and wound dehiscence, and impairing rehabilitation. We investigated the feasibility and initial efficacy of a multimodal swelling control intervention (MSI), comprised of an inelastic adjustable compression garment (CG), manual lymph drainage (MLD) massage, and home exercise program (HEP) after total knee arthroplasty (TKA) compared to a control group. METHODS: Sixteen individuals (mean age 64.7 ± 7.1y) performed MSI for three weeks after TKA, through day 21 (D21). Outcome measures included patient satisfaction, safety, patient adherence, and swelling measured by Single Frequency Bioimpedance Assessment (SF-BIA). All outcomes were measured preoperatively and at postoperative D4, D7, D14, D21 and, three weeks after discontinuing MSI, on D42. Efficacy of MSI was calculated with Hedge's g effect size estimates using the SF-BIA ratios for MSI versus CONTROL (N = 56; mean age 64.3 ± 9.3y) at key post operative time points. RESULTS: Patient satisfaction was 93% with no adverse events. Adherence to CG, MLD, and HEP were 85%, 99%, and 97% respectively. Peak swelling reduction with MSI was at D21 (Hedges' g = 1.60 at D21 (95% CI 0.99, 2.21)). Minimal change in swelling was observed three weeks after cessation of MSI on D42. CONCLUSIONS: The self-administered MSI program is feasible and demonstrated strong initial efficacy to control swelling after TKA. Minimal rebound swelling was observed once MSI was withdrawn at D21. Future studies should examine the efficacy of inelastic adjustable compression in a randomized controlled trial.

Purpose: To develop reference charts that describe normative quadriceps strength recovery after total knee arthroplasty (TKA) as measured by handheld dynamometry (HHD).Materials and Methods: We conducted a retrospective analysis of post-TKA quadriceps strength recovery in a longitudinal dataset consisting of both clinical and research HHD data. We created sex-specific models for recovery using Generalized Additive Models for Location, Scale, and Shape. We created reference charts from the models to display the recovery of population centiles over the first six postoperative months.Results: A total of 588 patient records with 1176 observations were analyzed. Reference charts for both sexes demonstrated a rapid increase in quadriceps strength over the first 60 postoperative days followed by a more gradual increase over the next 120 days. Males appeared to demonstrate faster recovery and greater strength on average compared to females. The quadriceps strength recovery of three female patient records was plotted on the reference chart to illustrate the charts' potential clinical utility.Conclusions: These reference charts provide normative data for quadriceps strength recovery after TKA as assessed by HHD. The reference charts may augment clinicians' ability to monitor and intervene upon quadriceps weakness-a pronounced and debilitating post-TKA impairment-throughout rehabilitation.Implications for RehabilitationHandheld dynamometry (HHD) is an objective and clinically feasible method for assessing muscle strength, but normative HHD values are lacking for quadriceps strength recovery after total knee arthroplasty (TKA).We created sex-specific reference charts which provide normative quadriceps strength HHD values for the first 180 days after TKA.These reference charts may improve clinicians' ability to monitor and intervene upon post-TKA quadriceps strength deficits.

OBJECTIVE: Prediction models can be useful tools for monitoring patient status and personalizing treatment in health care. The goal of this study was to compare the relative strengths and weaknesses of 2 different approaches for predicting functional recovery after knee arthroplasty: a neighbors-based "people-like-me" (PLM) approach and a linear mixed model (LMM) approach. MATERIALS AND METHODS: We used 2 distinct datasets to train and then test PLM and LMM prediction approaches for functional recovery following knee arthroplasty. We used the Timed Up and Go (TUG)-a common test of mobility-to operationalize physical function. Both approaches used patient characteristics and baseline postoperative TUG values to predict TUG recovery from days 1-425 following surgery. We then compared the accuracy and precision of PLM and LMM predictions. RESULTS: A total of 317 patient records with 1379 TUG observations were used to train PLM and LMM approaches, and 456 patient records with 1244 TUG observations were used to test the predictions. The approaches performed similarly in terms of mean squared error and bias, but the PLM approach provided more accurate and precise estimates of prediction uncertainty. DISCUSSION AND CONCLUSION: Overall, the PLM approach more accurately and precisely predicted TUG recovery following knee arthroplasty. These results suggest PLM predictions may be more clinically useful for monitoring recovery and personalizing care following knee arthroplasty. However, clinicians and organizations seeking to use predictions in practice should consider additional factors (eg, resource requirements) when selecting a prediction approach.
