Abstract
INTRODUCTION This biomechanical study aims to assess the function of patients who were treated non-operatively for delayed diagnosis Achilles tendon rupture. Patients were treated using the Swansea Morriston Achilles Rupture Treatment protocol (SMART), which is a physiotherapy led non-operative treatment program. METHODS 19 patients (16M:3F) were enrolled and prospectively assessed using Achilles Repair Scores (ARS)/Achilles Tendon Rupture Scores (ATRS) (PROMS), Ankle ROM and isokinetic peak torque for plantarflexion of the ankle. MRI scans of both the injured and uninjured TA were performed to compare both AP diameter and length. RESULTS Both ATRS and ARS improved between short- and long-term follow-up. The mean difference in plantar torque between the injured and uninjured leg was 21.9%. There was no significant difference in ankle plantarflexion or dorsiflexion. There was no significant difference in length of the injured and uninjured TA on MRI. Three patients failed the SMART protocol requiring surgical fixation. DISCUSSION The SMART protocol can be an effective method of treatment even in younger and active patients especially if delay to treatment is less than 12 weeks. It may still be preferable for patients with a large gap size or high functional demand to elect for surgical intervention, but clinicians should consider the SMART protocol as an alternative to surgery and discuss it with some patients as a viable alternative.

Abstract
BACKGROUND Some authors found that delayed repair of Achilles tendon ruptures achieved similar functional outcomes when compared with acute repair of Achilles tendon ruptures. The purpose of our study was to compare functional outcomes and complication rates of acute repair to delayed repair after Achilles tendon ruptures. METHODS PubMed, Embase (Ovid) and the Cochrane Library were searched. RESULTS For Achilles tendon rupture score (ATRS), the overall result revealed that there was no significant difference in ATRS between acute repair groups and delayed repair groups (P = 0.59). For Tegner scores, Halasi scores and Achilles tendon resting angle (ATRA), there was no significant difference between the two groups (P = 0.28, P = 0.47 and P = 0.68). There was no significant difference in the subjective assessment between acute repair groups and delayed repair groups (P = 0.84). However, delayed repair groups showed a higher incidence of complications than acute repair groups (P = 0.01). Subgroup analyses showed that the mean time from injury to surgery of delayed repair groups affect the pooled result substantially. For mean time less than 28d, there was no difference in the incidence of complications between acute repair groups and delayed repair groups (P = 0.09). However, for mean time more than 28d, delayed repair groups showed a higher incidence of complications than acute repair groups (P = 0.05). CONCLUSION Our study showed delayed repair could obtain similar functional outcomes and subjective assessment when compared with acute repair. However, the rate of complications after delayed repair was higher than that of early repair. Further high-quality randomized controlled trials (RCT) are needed to evaluate the difference.

Repair within the first 48 h in the treatment of acute Achilles tendon ruptures achieves the best biomechanical and histological outcomes. Knee Surg Sports Traumatol Arthrosc 2020; 28:2788-2797. [PMID: 31119340 DOI: 10.1007/s00167-019-05536-w] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/17/2019] [Accepted: 05/07/2019] [Indexed: 12/16/2022]
Abstract
PURPOSE To compare the biomechanical and histological properties of Achilles tendons repaired at different time points during the acute injury period. METHODS Thirty-six skeletally mature Sprague-Dawley rats underwent bilateral mid-substance Achilles tenotomy. The Achilles tendons were repaired either in the first 24 h (group 1), 24-48 h (group 2), 48-72 h (group 3), or > 72 h (mean: 120 ± 5.2 h) (group 4) after tenotomy. Six weeks after repair, nine tendons per group were assessed biomechanically and histologically. The Stoll histological scoring system was used for histological examination. The groups were compared with each other and native tendons (control group). The correlations between biomechanical and histological results were analysed. RESULTS There were no significant differences between groups 1, 2 and 3 regarding the mean load to failure; it was significantly lower in group 4. Healed tendons in groups 1, 2 and 3 had significantly greater stiffness than native tendons and group 4 tendons. All healed tendons had a larger cross-sectional area than native tendons. There was no significant difference in tendon length between the groups. There was no significant difference in Young's modulus between the groups; Young's modulus was lower in all the groups than in the control group. Group 1 had significantly higher extracellular matrix organization, cell alignment, cell distribution and nucleus morphology scores and total scores than group 4. Group 1 had significantly higher extracellular matrix organization, cell distribution, vascularization and inflammation scores and total scores than group 3. A significant positive correlation was detected between the maximum load to failure and total histological score. CONCLUSION Repair of acute Achilles tendon rupture within 48 h, and especially in the first 24 h, provides better biomechanical and histological outcomes. In the clinical practice, the data could be used to decrease re-rupture rates, to achieve more anatomical tendon healing and to implement more effective post-operative rehabilitation programme.

Abstract
PURPOSE This retrospective study aimed to determine the patient-reported and functional outcome of patients with delayed presentation, who had received no treatment until 14 days following injury of Achilles tendon rupture repaired with minimally invasive surgery and were compared with a group of sex- and age-matched patients presenting acutely. Based on the outcomes following delayed presentation reported in the literature, it was hypothesized that outcomes would be inferior for self-reported outcome, tendon elongation, heel-rise performance, ability to return to play, and complication rates than for acutely managed patients. METHODS Repair was performed through an incision large enough to permit mobilisation of the tendon ends, core suture repair consisting of a modified Bunnell suture proximally and a Kessler suture distally and circumferential running suture augmentation. RESULTS Nine patients presented 21.8 (14.9) days (range 14-42 days) after rupture. The rate of delayed presentation was estimated to be 1 in 10. At 12 months following repair, patients with delayed treatment had median (range) ATRS score of 90 (69-99) compared with 94 (75-100) in patients treated acutely presenting 0.66 (1.7) (0-5) days. There were no significant differences between groups: ATRA [mean (SD) delayed: - 6.9° (5.5), acute: - 6° (4.7)], heel-rise height index [delayed: 79% (20), acute: 74% (14)], or heel-rise repetition index [delayed: 77% (20), acute: 71% (20)]. In the delayed presentation group, two patients had wound infection and one iatrogenic sural nerve injury. CONCLUSIONS Patients presenting more than 2 weeks after Achilles tendon rupture may be successfully treated with minimally invasive repair. LEVEL OF EVIDENCE III.

Abstract
BACKGROUND Minimally invasive repair of acute Achilles tendon ruptures has been performed for several years, resulting in reduced morbidity as compared with open repair. HYPOTHESIS A minimally invasive technique can be used to manage Achilles tendon ruptures in patients presenting between 14 and 30 days from injury. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS We prospectively recruited 21 consecutive patients who presented between 14 and 30 days after the index injury, and we compared them with 21 patients who were matched according to sex, age (±2 years), and level of activity, who presented within 14 days of the index injury. All patients underwent the same minimally invasive procedure under local anesthesia: a core suture repair consisting of a modified Bunnell suture in the proximal stump and a modified Kessler suture in the distal stump. RESULTS At 12 months after minimally invasive repair, patients with delayed treatment had a median Achilles tendon rupture score of 91 (SD, 2.4; range, 87-96) as compared with 91 (SD, 2.2; range, 86-96) in patients treated acutely, who presented at a median 2.4 days (range 1-6 days) from the injury. There were no significant differences between groups in terms of mean (SD) Achilles tendon resting angle: delayed repair group, -3.9° (2.0); acute repair group, -3.7° (1.9) (P = .69). No patient in either group developed a wound infection. One patient in the acute group experienced an iatrogenic sural nerve injury. CONCLUSION Patients with Achilles tendon rupture treated by percutaneous repair 14 to 30 days after injury achieved similar results at 1 year as patient treated <14 after injury.
