BACKGROUND The objective of this study is to review and summarize recent developments in wearable technology detailing the key enabling technologies (i.e., sensor components) and applications of wearable technology as they relate to lower extremity osteoarthritis. OBJECTIVE The objective of this study is to review and summarize recent developments in wearable technology detailing the key enabling technologies (i.e., sensor components) and applications of wearable technology as they relate to lower extremity osteoarthritis. METHODS A literature search was performed in March 2021 using the PubMed and EMBASE databases for publications on wearable movement technologies in lower-limb OA. Papers published within the previous 5 years were identified. The search was limited to original research studies published in English. Duplicate studies, systematic reviews, conference abstracts, and study protocols were removed. Sample keywords and their combinations included: (osteoarthritis OR TKA OR total knee arthroplasty OR total knee replacement) AND (wearable* OR sensor). RESULTS From the literature, 72 studies were determined relevant and subsequently included in this review. Wearable technology has successfully been implemented for gait assessment, movement pattern training using feedback, assessment of intervention outcomes, and physical activity monitoring. Additionally, some studies demonstrated algorithms or measurement systems that could be used for movement pattern training with feedback in future implementations. Study participants identified appearance and comfort during use as key aspects for the acceptance of wearable technology, and enjoyed seeing both quantitative sensor data as well as qualitative patient-reported outcomes. CONCLUSIONS Advancements in wearable sensor technology allow for data collection and analysis in both accurate and unobtrusive ways. The technology can be used to passively collect data, implement exercise interventions, or actively retrain movement patterns. Future opportunities remain to have more efficient, smaller systems and provide biofeedback for new, previously unused metrics.

Introduction: Physical rehabilitation is widely used following total knee arthroplasty (TKA), while no consensus has been reached regarding the optimal dosage, frequency and modality. Before a standardized protocol can be established, it is important to investigate the true efficacy for physical rehabilitation following TKA. Objective: To examine if physical rehabilitation is superior to no physical rehabilitation following total knee arthroplasty in terms of patient-reported outcomes for function and pain. Methods: The search strategy was conducted in five databases (MEDLINE, Embase, Cinahl, CENTRAL and SPORTDiscus) with eligibility criteria for inclusion being: Randomised controlled trials comparing patients receiving physical rehabilitation with a group receiving no physical rehabilitation following unilateral TKA. Potential sources of bias were assessed according to the Cochrane Risk of Bias Tool. The Consensus on Exercise Reporting Template (CERT) was used to extract and report exercise interventions from the included trials. Results: Only two of 3254 identified trials fulfilled the eligibility criteria and were included. The two trials were judged as being of moderate to good methodological quality, but lacking in the reporting of their exercise interventions. Difference in outcome measurements and interventions makes between-study comparison inconclusive. Conclusions: No conclusion regarding the superiority of physical rehabilitation to no-intervention following TKA can be drawn from the results of this systematic review. Further research is required to establish the true effectiveness of physical rehabilitation following TKA. Systematic review registration number: PROSPERO 2018 CRD42018094785.

AbstractDespite multiple studies, there remains a debate on the safety of bilateral total knee arthroplasty (BTKA) in the average age patient, with a paucity of data on the outcome of BTKA in an elderly population. This study included 89 patients aged 80 years and older undergoing sequential BTKA over 14 years were identified in a prospectively collected database. Two matched comparison groups were created: patients under 80 undergoing sequential BTKA and patients over 80 undergoing unilateral TKA (UTKA). An analysis of complications, mortality, revision, and patient-reported outcome measures was performed. Mean age of the elderly cohorts was similar: 82.6 for BTKA and 82.9 for UTKA. The average age BTKA cohort had a mean age of 69.1. Complication rates were higher in bilateral cohorts, more so in the elderly BTKA cohort. Pulmonary embolism (PE) was observed in bilateral cohorts only. In these patients, history of PE and ischemic heart disease was a strong predictive factor for developing a major complication. There was no difference in revision rates and infection rates between the three cohorts, and no difference in patient survivorship between the two elderly cohorts. Through the combination of low revision and high survivorship rates and comparable clinical outcomes, this article demonstrates that simultaneous BTKA is an appropriate option to consider for an elderly patient, with proper patient selection and perioperative management. The demonstrated risk groups show that emphasis on patient selection should be focused on medical history rather than chronological age.

Abstract Background The purpose of this study was to determine the mid-term clinical, radiographic and health-related quality of life (HRQoL) outcomes and define the survival rate in patients who had undergone revision total knee arthroplasty (TKA) using the single rotating hinged knee (RHK) design. Methods Between January 2004 and December 2013, 125 revision TKAs were performed at our institution using the single RHK implant. We conducted both a retrospective analysis of prospectively collected outcome data of these patients and a prospective follow-up study of all 39 living patients (41 knees). The follow-up phase included an optional extra follow-up visit, PROM questionnaires, and plain radiographs. Results The ten-year Kaplan-Meier survival rate of the revision RHK knees was 81.7% (95% CI 71.9–91.6%) with re-revision for any reason as the endpoint. Overall, 15 knees (12% of the total) underwent re-revision surgery during the follow-up. The median follow-up was 6.2 years (range, 0–12.7 years) post-operatively for the baseline group. One mechanical hinge mechanism-related failure occurred without any history of trauma or infection. At the time of the final follow-up, the majority of patients evinced a fairly good clinical outcome measured with patient-reported outcome measures and none of the components were radiographically loose. Conclusion We found that in patients undergoing complex revision TKA, fairly good functional outcome and quality of life can be achieved using an RHK implant. Further, it seems that in this type of patient cohort, revision TKA using an RHK implant relieves pain more than it improves ability to function. The NexGen® RHK design can be regarded as a suitable option in complex revision TKA.

Abstract Background The FINE total knee was developed in Japan and clinical use began in 2001. It has unique design features, including an oblique 3o femorotibial joint line that reproduces anatomical geometry. Although 20 years have passed since the FINE knee was clinically used for the first time in Japan, a formal clinical evaluation including patient-reported and radiographic outcomes has not been undertaken. Methods A total of 175 consecutive primary cruciate-retaining (CR)-FINE total knee arthroplasties (TKAs) at our hospital between February 2015 and March 2017 were included in this study. Three years postoperatively, range of motion (ROM), Knee Society Score (KSS), Knee Injury and Osteoarthritis Outcome Score (KOOS) and Forgotten Joint Score (FJS) were recorded and compared with preoperative scores. Radiographic analyses including mechanical alignment, component alignment, and incidence of radiolucent lines also were undertaken based on the radiographs 3 years postoperatively. Results One-hundred twenty-two knees (70%) were available for 3-year follow-up data using KOOS, except for the sports subscale. Postoperative KOOS-symptom, −pain and -ADL were > 85 points, but KOOS-sports, −QOL and FJS were less satisfactory. ROM, KSS and all the subscales of KOOS were significantly improved compared with preoperative scores. Postoperative mean FJS was 66 and was significantly correlated with all the subscales of KOOS, but not with postoperative ROM. Radiolucent lines ≧1 mm wide were detected in five knees (4.1%). There were no major complications needing revision surgeries. Conclusions Patient-reported outcomes (PROs) for symptoms, pain and ADL after the CR-FINE TKA were generally improved, but those for sports, QOL and FJS were improved less. The incidence of radiolucent lines was rare but detected around the femoral components. With the mid- to long-term follow-up, improvements of surgical technique will be necessary to achieve better PROs from patients receiving the FINE knee.

Abstract Background Total knee replacement operation (TKR) is the treatment of choice in severe knee osteoarthritis (OA). Rehabilitation post-TKR is still not well studied. The aim of this study was to compare between the high-intensity (HI) rehabilitation program and the low-intensity (LI) rehabilitation program following TKR. Results At 1 month following the TKR operations, significant improvements were found in the first group compared to the second group in all the measured parameters except for the knee range of motion (ROM). At 3 and 12 months follow-up periods, there were statistically significant differences between both groups in all the evaluated parameters except for the numeric pain rating scale and the knee ROM. Conclusions Both high-intensity and low-intensity rehabilitation programs are effective; however, HI program had superior functional gain and patient-reported outcomes compared to the LI program. Moreover, HI group has a long-term functional gain.

AbstractThis is a retrospective study. Prior studies have characterized the deleterious effects of narcotic use in patients undergoing primary total knee arthroplasty (TKA). While there is an increasing revision arthroplasty burden, data on the effect of narcotic use in the revision surgery setting remain limited. Our aim was to characterize the effect of active narcotic use at the time of revision TKA on patient-reported outcome measures (PROMs). A total of 330 consecutive patients who underwent revision TKA and completed both pre- and postoperative PROMs was identified. Due to differences in baseline characteristics, 99 opioid users were matched to 198 nonusers using the nearest-neighbor propensity score matching. Pre- and postoperative knee disability and osteoarthritis outcome score physical function (KOOS-PS), patient reported outcomes measurement information system short form (PROMIS SF) physical, PROMIS SF mental, and physical SF 10A scores were evaluated. Opioid use was identified by the medication reconciliation on the day of surgery. Propensity score–matched opioid users had significantly lower preoperative PROMs than the nonuser for KOOS-PS (45.2 vs. 53.8, p < 0.01), PROMIS SF physical (37.2 vs. 42.5, p < 0.01), PROMIS SF mental (44.2 vs. 51.3, p < 0.01), and physical SF 10A (34.1 vs. 36.8, p < 0.01). Postoperatively, opioid-users demonstrated significantly lower scores across all PROMs: KOOS-PS (59.2 vs. 67.2, p < 0.001), PROMIS SF physical (43.2 vs. 52.4, p < 0.001), PROMIS SF mental (47.5 vs. 58.9, p < 0.001), and physical SF 10A (40.5 vs. 49.4, p < 0.001). Propensity score–matched opioid-users demonstrated a significantly smaller absolute increase in scores for PROMIS SF Physical (p = 0.03) and Physical SF 10A (p < 0.01), as well as an increased hospital length of stay (p = 0.04). Patients who are actively taking opioids at the time of revision TKA report significantly lower preoperative and postoperative outcome scores. These patients are more likely to have longer hospital stays. The apparent negative effect on patient reported outcomes after revision TKA provides clinically useful data for surgeons in engaging patients in a preoperative counseling regarding narcotic use prior to revision TKA to optimize outcomes.

Abstract Objective The aim of this study was to evaluate the completeness of reporting of exercise adherence and exercise interventions delivered as part of clinical trials of post-operative total knee replacement (TKA) rehabilitation. Design: Scoping review Literature search A literature search was conducted in PubMed, EMBASE, AMED, CINAHL, SPORTDiscus and Cochrane Library. Study selection criteria All randomized controlled trials (RCT) that examined post-operative exercise-based interventions for total knee arthroplasty were eligible for inclusion. Studies that were multifactorial or contained exercise interventions for both hip and knee arthroplasty were also included. Data synthesis The definition, type of measurement used and outcome for exercise adherence were collected and analyzed descreptively. Quality of reporting of exercise interventions were assessed using the Consensus for Exercise Reporting Tool (CERT) and the Cochrane Risk of Bias Tool. Results There were a total of 112 RCTs included in this review. The majority of RCTs (63%, n = 71) did not report exercise adherence. Only 23% (n = 15) of studies provided a definition of adherence. RCTs were of poor quality, with 85% (n = 95) of studies having high or unclear risk of bias. Reporting of exercise interventions was poor, with only 4 items (of 19) (21%) of the CERT adequately reported (88–99%), with other items not fulfilled on at least 60% of the RCTs. There were no RCTs that had fulfilled all the criteria for the CERT. Conclusion The RCTs included in this study poorly reported exercise adherence, as well as description of the post-operative TKA rehabilitation intervention. Future RCTs should use valid and reliable measures of adherence and a proper tool for reporting of exercise interventions (e.g., CERT, TiDER). Pre-registration OSF:https://osf.io/9ku8a/

AbstractThe present study serves to establish Patient Reported Outcomes (PROs) as a tool for strengthening patient involvement and measuring outcomes in orthopaedic outpatient rehabilitation. Assessments by FFbH-R (Hannover Back Function Questionnaire for patients with back problems), Quick-DASH (Disabilities of Arm, Shoulder, and Hand Score for patients with upper extremity lesions), and LEFS (Lower Extremity Function Scale for patients with lower extremity lesions) were employed in 20 outpatient rehabilitation centres over a period of 12 months to evaluate changes in performance and participation from the subjective patient perspective. The following questionnaires were used: FFbH-R status post: lumbar disc surgery; cervical disc surgery; spinal canal decompression; conservative back pain treatment; other; Quick-DASH status post: rotator cuff reconstruction; shoulder arthroplasty; fracture (conservative or osteosynthesis); other; LEFS status post: hip arthroplasty; knee arthroplasty; anterior cruciate ligament repair; osteotomy; fracture (conservative treatment or osteosynthesis); other. Analysis of the 6,751 usable data sets demonstrated significant positive changes in all scores and diagnostic subgroups. The mean difference in score was 14.2 points in the FFbH-R, − 22 points in the Quick-DASH and 18 points in the LEFS. Thus, this study proves the positive effects of orthopaedic rehabilitation in an outpatient setting. PROs were instituted on a permanent basis in seven of the participating institutions.

Purpose: This study investigated the clinical effects of different patellar components without being affected by the femoral component design in total knee arthritis (TKA) for patients with knee osteoarthritis (OA). Methods: In total, 48 patients with OA who met the criteria of the American College of Rheumatology for OA were enrolled and randomly assigned in a 1:1 ratio to two groups according to the usage of patellar component design for TKA (medialized dome type [dome group] or medialized anatomic type [anatomic group]). To evaluate the clinical outcomes for TKA, knee range of motion (ROM), pain intensity of 0–100 mm visual analog scale (pain VAS), and the Japanese Knee Osteoarthritis Measure (JKOM) score were obtained at baseline and year 1. Results: The difference in knee ROM, pain VAS, or total JKOM score at year 1 was not significant between the dome and anatomic groups ( p = 0.398, 0.733 and 0.536, respectively). Moreover, similar results were obtained for changes in knee ROM, pain VAS, or total JKOM scores from baseline. In both groups, the pain VAS and total JKOM scores were significantly improved at year 1. Conclusion: Both dome and anatomic groups in TKA are significantly effective for pain and function using the JKOM score. However, their efficacy did not differ, according to the JKOM score. Results of this study are rare information focusing on the patellar component design and provide one of the insights into the TKA clinical management.
