Abstract
To explore the knowledge, attitude, and practice (KAP) towards enhanced recovery after surgery (ERAS) among colorectal cancer (CRC) patients. This cross-sectional study included CRC patients who underwent selective operation at the author's Hospital, between April 2021 and April 2023. Their demographic characteristics and KAP towards ERAS were collected using a self-designed questionnaire. A total of 652 valid questionnaires were collected, with knowledge, attitude, and practice scores of 37.29 ± 11.35 (possible range: 11-55), 39.51 ± 6.40 (possible range: 11-55), and 6.53 ± 2.21 (possible range: 0-8), respectively. A positive correlation was found between knowledge and attitude (r = 0.291, P < 0.001), knowledge and practice (r = 0.292, P < 0.001), and attitude and practice (r = 0.363, P < 0.001). Structural equation model (SEM) analysis showed that knowledge had a significant direct effect on attitude (β = 0.164, P < 0.001) and attitude had direct effect on practice (β = 0.099, P < 0.001), indicating an indirect effect of knowledge on practice. Attitude also had a direct effect on practice (β = 0.038, P < 0.001). CRC patients showed moderate knowledge and attitude, and proactive practice towards ERAS. Further improvement of knowledge may improve their attitude and practice, leading to better outcomes and quality of care among CRC patients.

Abstract
CASE A 19-year-old female athlete experienced calf pain during sport. A complete Achilles tendon rupture was diagnosed 4 weeks after injury. Ultrasound revealed discontinuity of the Achilles tendon with 2.0 cm of diastasis, persisting in plantarflexion. Plantarflexion immobilization was initiated, and progressive dorsiflexion was used until 10 weeks from injury. At 1 year from injury, ankle magnetic resonance imaging revealed a contiguous tendon, the patient was pain-free, and had returned to high-level athletics with equivalent sport performance relative to her preoperative status. CONCLUSION Certain Achilles tendon ruptures in young people may be treated nonoperatively with good clinical outcomes, even if diagnosis and immobilization are delayed and tendon diastasis persists in maximum plantarflexion.

Achilles tendon thickening does not affect elasticity and functional outcome after surgical repair of Achilles rupture: A retrospective study. Chin J Traumatol 2023; 26:323-328. [PMID: 37940448 PMCID: PMC10755773 DOI: 10.1016/j.cjtee.2023.10.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/31/2023] [Revised: 09/21/2023] [Accepted: 10/01/2023] [Indexed: 11/10/2023] Open
Abstract
PURPOSE Previous studies have confirmed that Achilles tendon occurs Achilles thickening after repair surgery of the rupture. Although this mechanism has been elucidated in the laboratory, there are few reports on its impact on clinical function. We designed a retrospective study to investigate the Achilles thickening after Achilles tendon rupture repair and its correlation between the elasticity and postoperative function. METHODS In this retrospective analysis, patients who underwent surgical treatment for acute Achilles tendon rupture from April 2016 to April 2020 were included. All the patients were regularly followed up at 3 months, 1 year, and 2 years after surgery. American Orthopaedic Foot Ankle Surgeon (AOFAS) scale and Leppilahti score were used to evaluate functional outcomes. Achilles elasticity was measured by ultrasound shear wave of elasticity. Achilles thickening was calculated as maximal transverse and longitudinal diameter in cross-sectional plane of magnetic resonance scan. Sample t-tests was used for different follow-up periods. Correlation between Achilles thickening and other factors were analyzed using Pearson's method. p < 0.05 indicates a statistically significant difference. RESULTS AOFAS scale and Leppilahti score at 1 year were significantly higher than at 3 months postoperatively (both p < 0.001). These functional scales were also improved at 2-year follow-up significantly (both p < 0.001). The dorsiflexion difference showed gradually recovery in each follow-up period (t = -17.907, p < 0.001). The elasticity of the Achilles appeared to continuously decreases during the postoperative follow-up period in all position sets (p < 0.001). In thickening evaluation, the cross-sectional area of the thickest plane of Achilles was significantly higher at 1 year postoperatively (310.5 ± 25.2) mm2 than that at 3 months postoperatively ((278.0 ± 26.2) mm2, t = -8.219, p < 0.001) and became thinner in 2-year magnetic resonance scan ((256.1 ± 15.1) mm2, t = 16.769, p < 0.001). The correlations between Achilles thickening, elasticity, and functional outcome did not show statistical significance (p > 0.05) in every follow-up period. CONCLUSION Achilles tendon thickens after surgery in the 1st year, but begins to gradually return to thinning about 2 years after surgery. There was no significant correlation between the increase and decrease of thickening and the patients' clinical function scores, Achilles elasticity, and bilateral ankle dorsiflexion difference.

Abstract
PURPOSE To systematically review and evaluate the current meta-analyses for the treatment of acute Achilles tendon rupture (AATR). This study can provide clinicians with a clear overview of the current literature to aid clinical decision-making and the optimal formulation of treatment plans for AATR. METHODS Two independent reviewers searched PubMed and Embase on June 2, 2022 based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Assessment of evidence was twofold: level of evidence (LoE) and quality of evidence (QoE). LoE was evaluated using published criteria by The Journal of Bone and Joint Surgery and the QoE by the Assessing the Methodological Quality of Systematic Reviews (AMSTAR) scale. Pooled complication rates were highlighted for significance in favour of one treatment arm or no significance. RESULTS There were 34 meta-analyses that met the eligibility criteria, with 28 studies of LoE 1, and the mean QoE was 9.8 ± 1.2. Significantly lower re-rupture rates were reported with surgical (2.3-5%) versus conservative treatment (3.9-13%), but conservative treatment was favoured in terms of lower complication rates. The re-rupture rates were not significantly different between percutaneous repair or minimally invasive surgery (MIS) compared to open repair, but MIS was favoured in terms of lower complication rates (7.5-10.4%). When comparing rehabilitation protocols following open repair (four studies), conservative treatment (nine studies), or combined (three studies), there was no significant difference in terms of re-rupture or obvious advantage in terms of lower complication rates between early versus later rehabilitation. CONCLUSION This systematic review found that surgical treatment was significantly favoured over conservative treatment for re-rupture, but conservative treatment had lower complication rates other than re-rupture, notably for infections and sural nerve injury. Open repair had similar re-rupture rates to MIS, but lower complication rates; however, the rate of sural nerve injuries was lower in open repair. When comparing earlier versus later rehabilitation, there was no difference in re-rupture rates or obvious advantage in complications between open repair, conservative treatment, or when combined. The findings of this study will allow clinicians to effectively counsel their patients on the postoperative outcomes and complications associated with different treatment approaches for AATR.

Abstract
INTRODUCTION Optimal postoperative rehabilitation regimen for acute Achilles tendon rupture (AATR) remains unclear. It is important to evaluate whether early functional weight-bearing rehabilitation program after minimally invasive repair results in an earlier return to pre-injury activity but increases the risk of re-rupture. MATERIALS AND METHODS This was a prospective randomized controlled trial involving 68 AATR patients undergoing minimally invasive surgery. 34 patients were enrolled in early weight‑bearing mobilization accelerated rehabilitation group (AR group); 34 patients were enrolled in the traditional rehabilitation (TR) group. Outcomes measures included American Orthopaedic Foot and Ankle Society Score (AOFAS) score and Achilles Tendon Total Rupture Score (ATRS) score before surgery and 3, 6, and 12 months after surgery, incidence rate of Achilles tendon re-rupture and total complications, length of hospital stay, time return to work and sports. RESULTS There was no significant difference in preoperative basic data between the two groups. However, AOFAS score and ATRS score were better in AR group than TR group at 3 months postoperatively (92.4 ± 3.5 vs 88.3 ± 4.5, P < 0.01; 91.1 ± 4.4 vs 88.9 ± 3.4, P = 0.03, respectively), the mean length of hospital stay (4.7 ± 1.5 vs 7.6 ± 2.0 days, P < 0.01) and time return to work (4.5 ± 1.0 vs 7.5 ± 1.6 weeks, P < 0.01) were shorter in AR group than in TR group. No statistical significance was calculated in patient-reported outcomes during the rest of the follow-up time and complications. CONCLUSION Early accelerated rehabilitation with weight-bearing in patients with AATR after minimally invasive surgery results in better early functional outcomes and shows similar security and feasibility.

Abstract
BACKGROUND Shear wave elastography (SWE) has been used to examine the elasticity of a ruptured Achilles tendon; however, the healing process of a ruptured tendon has not been studied yet. This study aimed to detail the change in mechanical properties of a healing Achilles tendon rupture managed conservatively or surgically using SWE. METHODS Using a prospective cohort study design, we evaluated the patients treated conservatively (conservative group) and surgically (surgical group) with the "gift-box" technique for an isolated index acute Achilles tendon rupture during their healing process. SWE measurements were taken of both the injured and uninjured sides every 4 weeks up to 24, 36, and 48 weeks after treatment. Additionally, tendon thickness and power Doppler (PD) grade were measured at the same time points as SWE measurements. The American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot rating system score and Achilles tendon Total Rupture Score (ATRS) were compared at 24 and 48 weeks. RESULTS The ruptured Achilles tendon obtained an SWE value comparable with the unruptured side at 12 weeks in the conservative group and at 4 weeks with surgical group. The surgical group had significantly higher SWE values up to 24 weeks compared with the conservative group. Additionally, this group had a significantly larger increase in tendon thickness in nearly all periods. Both treatment groups were comparable regarding the PD grade, AOFAS score, and ATRS. CONCLUSION SWE is a convenient noninvasive method to determine the progress of the healing process after tendon injury. Our analysis using SWE has revealed the detailed chronologic changes in SWE values and related mechanical properties of a healing Achilles tendon rupture, which can be used for devising appropriate rehabilitation protocols.

Abstract
BACKGROUND Early tensile loading improves material properties of healing Achilles tendon ruptures in animal models and in surgically treated human ruptures. However, the effect of such rehabilitation in patients who are nonsurgically treated remains unknown. HYPOTHESIS In nonsurgically treated Achilles tendon ruptures, early tensile loading would lead to higher elastic modulus 19 weeks after the injury compared with controls. STUDY DESIGN Randomized controlled trial; Level of evidence, 2. METHODS Between October 2015 and November 2018, a total of 40 nonsurgically treated patients with acute Achilles tendon rupture were randomized to an early tensile loading (loaded group) or control group. Tantalum bead markers were inserted percutaneously into the tendon stumps 2 weeks after the injury to allow high-precision measurements of callus deformation under mechanical testing. The loaded group used a training pedal twice daily to produce a gradual increase in tensile load during the following 5 weeks. Both groups were allowed full weightbearing in an ankle orthosis and unloaded range of motion exercises. Patients were followed clinically and via roentgen stereophotogrammetric analysis and computed tomography at 7, 19, and 52 weeks after the injury. RESULTS The mean ± standard deviation elastic modulus at 19 weeks was 95.6 ± 38.2 MPa in the loaded group and 108 ± 45.2 MPa in controls (P = .37). The elastic modulus increased in both groups, although it was lower in the loaded group at all time points. Tendon cross-sectional area increased from 7 weeks to 19 weeks, from 231 ± 99.5 to 388 ± 142 mm2 in the loaded group and from 188 ± 65.4 to 335 ± 87.2 mm2 in controls (P < .001 for the effect of time). Cross-sectional area for the loaded group versus controls at 52 weeks was 302 ± 62.4 mm2 versus 252 ± 49.2 mm2, respectively (P = .03). Gap elongation was 7.35 ± 13.9 mm in the loaded group versus 2.86 ± 5.52 mm in controls (P = .27). CONCLUSION Early tensile loading in nonsurgically treated Achilles tendon ruptures did not lead to higher elastic modulus in the healing tendon but altered the structural properties of the tendon via an increased tendon thickness.
