Abstract
BACKGROUND Achilles tendon ruptures often result in long-term functional deficits despite accelerated (standard) rehabilitation. PURPOSE/HYPOTHESIS The purpose of this study was to investigate if delayed loading would influence functional, clinical, and structural outcomes of the muscles and tendon 1 year after a surgical repair. It was hypothesized that delaying the loading would reduce the heel-rise height deficit 1 year after Achilles tendon rupture. STUDY DESIGN Randomized controlled trial; Level of evidence, 1. METHODS In total, 48 patients with a surgically repaired Achilles tendon rupture were randomized to 2 groups: the standard group received the currently accepted rehabilitation, and the delayed group received the same rehabilitation except that initial loading was delayed by 6 weeks. The primary outcome was the heel-rise height difference between the injured and uninjured sides at 1 year. The secondary outcomes were (1) tendon length measured with magnetic resonance imaging, (2) muscle fascicle length and pennation angle of the gastrocnemius medialis muscle, (3) Doppler activity measured with ultrasonography, (4) Achilles tendon Total Rupture Score (ATRS), and (5) isometric muscle strength. RESULTS The mean heel-rise height deficits for the standard and delayed groups were -2.2 cm and -2.1 cm, respectively (P = .719). The soleus part of the tendon was already elongated 1 week after surgery in both groups without a between-group difference (side-to-side difference: standard, 16.3 mm; delayed, 17.5 mm; P = .997) and did not change over 52 weeks. The gastrocnemius tendon length was unchanged at 1 week but elongated over time without a between-group difference (side-to-side difference at 52 weeks: standard, 10.5 mm; delayed, 13.0 mm; P = .899). The delayed group had less Doppler activity at 12 weeks (P = .006) and a better ATRS (standard, 60 points; delayed, 72 points; P = .032) at 52 weeks. CONCLUSION Delayed loading was not superior to standard loading in reducing the heel-rise height difference at 1 year. The data indirectly suggested reduced inflammation in the initial months and a better patient-reported outcome at 1 year in the delayed group. The soleus part of the tendon was already markedly elongated (35%) 1 week after surgery, while the length of the gastrocnemius tendon was unchanged at 1 week but was 6% elongated at 1 year. Together, these data indirectly suggest that the delayed group fared better, although this finding needs to be confirmed in future investigations.

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
Background An open Achilles tendon repair is performed in patients who have suffered an acute rupture. All patients with this injury should be counseled on their treatment options, which include open operative repair and functional rehabilitation. We prefer the use of an open repair in high-level athletes and those who have delayed presentation. Typically, this injury-and the resulting open repair-are seen in young or middle-aged patients as well as athletes. Operative repair of a ruptured Achilles tendon is associated with a much faster return to activity/sport when compared with nonoperative alternatives. This surgical procedure is especially useful in allowing this patient population to return to their previous activity level and functional capacity as quickly as possible. Description Open repair of a ruptured Achilles tendon begins with a 6 to 8-cm incision over the posteromedial aspect of the lower leg. Superficial and deep dissections are performed until the 2 ends of the ruptured tendon are identified. Adhesions are debrided to adequately mobilize and define the proximal and distal segments of the tendon. With use of a fiber tape suture, a modified locking Bunnell stitch is utilized to secure both ends. The fiber tape is tied securely, and the repair is reinforced with Vicryl suture (Ethicon). Once the tendon is repaired, the paratenon layer is identified and repaired with a running 0 or 2-0 Vicryl suture. This is an important step to minimize postoperative wound complications. The wound is then closed, and the extremity is splinted in maximum plantar flexion. Alternatives Alternative treatments include minimally invasive surgical techniques such as percutaneous Achilles tendon repair and nonoperative treatment with functional rehabilitation, which can provide excellent outcomes but can also lead to a slight decrease in explosiveness as the patient returns to sport1,2. Rationale Nonoperative and operative treatment of Achilles tendon rupture can both result in excellent patient outcomes. Appropriate patient selection is critical. Younger patients hoping to return to more highly competitive athletics should consider operative repair3. Possible differences have been identified in peak torque when comparing operative versus nonoperative treatment, with patients who had undergone operative repair having greater peak torque (i.e., explosiveness)2. Otherwise, findings are similar between treatment options as long as the patients meet the criteria for nonoperative treatment. Expected Outcomes Overall, the scientific literature demonstrates that the functional outcomes following operative repair are good to excellent. In a study by Hsu et al.4, 88% of patients were able to return to their baseline level of activity by 5 months postoperatively, with a complication rate of 10.6% and no reruptures. In a recent meta-analysis by Meulenkamp et al.5, the authors found that operative repair of Achilles tendon rupture was associated with a reduced risk of rerupture compared with primary immobilization (i.e., conventional cast immobilization with delayed weight-bearing for at least 6 weeks only). However, open surgical repair, minimally invasive repair, and functional rehabilitation all had similar risk of rerupture5. In a review by Ochen et al.6 that analyzed 29 studies with a total of 15,862 patients, operative repair was associated with a significantly lower risk of rerupture compared with nonoperative treatment (2.3% versus 3.9%, respectively). However, operative treatment was also associated with a significantly higher complication rate compared with nonoperative treatment (4.9% versus 1.6%, respectively)6. Finally, in a meta-analysis by Soroceanu et al.7, the authors found that if early range-of-motion protocols and functional rehabilitation were utilized, operative and nonoperative treatment resulted in similar outcomes and equivalent rates of rerupture. Important Tips To prevent rerupture of an Achilles tendon, remind patients to engage in adequate stretching and warming prior to physical activity.Palpate and locate the tendon defect prior to making the first incision.Immobilize the ankle joint in a splint for 2 weeks postoperatively in maximum plantar flexion.Pitfalls include:○ Poor suture management leading to tangling in the repair.○ Undertensioning or overtensioning of the repair, which can be avoided by sterilely draping out both legs and checking resting tension intraoperatively.○ Failure to close the paratenon, causing scarring of the skin or surrounding tissues, which can be avoided by making a relieving incision on the deep surface of the paratenon.○ Leaving suture knots on the dorsal side of the repair that may aggravate the skin.

Abstract
BACKGROUND Deficits in calf muscle function and heel-rise performance are common after an Achilles tendon rupture (ATR) and are related to tendon elongation and calf muscle atrophy. Whether early functional mobilization (EFM) can improve calf muscle function compared with standard treatment (ST) with 2 weeks of immobilization and unloading in a plaster cast is unknown. HYPOTHESIS EFM would lead to superior recovery of heel-rise performance, as demonstrated by more symmetrical side-to-side ankle and knee joint kinematics, compared with ST. STUDY DESIGN Cohort study; Level of evidence, 2. METHODS In total, 47 patients with an ATR were prospectively included and treated with open surgical repair and randomized 2:1 postoperatively to either EFM or ST. Overall, 29 patients were treated with a dynamic orthosis (EFM), and 18 underwent ST. At 8 weeks and 6 months after ATR repair, 3-dimensional motion analysis of heel-rise performance was conducted. At 6 months, tendon length and muscle volume were assessed with ultrasound imaging, calf muscle function with the heel-rise test, and patient-reported outcomes with the Achilles tendon Total Rupture Score. RESULTS At 8 weeks and 6 months, there were no significant group differences between the EFM and ST groups in heel-rise performance, but significant side-to-side differences in ankle and knee kinematics were detected. At 8 weeks and 6 months, both the EFM and ST groups showed a significantly decreased peak ankle plantarflexion angle and increased knee flexion angle on the injured limb compared with the uninjured limb during bilateral heel raises. Linear regression demonstrated that greater atrophy of the medial gastrocnemius muscle (P = .008) and higher body weight (P < .001) were predictors of a decreased maximum peak ankle plantarflexion angle on the injured limb at 6 months. CONCLUSION EFM after an ATR repair did not lead to superior recovery of calf muscle function, as assessed by heel-rise performance, compared with ST. Increased knee flexion seemed to be a compensatory strategy for decreased ankle plantarflexion. Medial gastrocnemius atrophy and increased body weight were additional factors associated with a decreased ankle plantarflexion angle. REGISTRATION NCT02318472 (ClinicalTrials.gov identifier).

Abstract
This study aimed to compare recovery of gait patterns in patients treated with early functional mobilization (EFM) or standard treatment (ST) after Achilles tendon rupture repair. Second, this study aimed to explore associations between gait patterns and tendon elongation and calf muscle atrophy, respectively. Forty-seven patients (12 females), mean age 38.7 (7.3) years, were included. Patients were postoperatively randomized to EFM (n = 29), including immediate weightbearing and ankle motion for 6 weeks, or ST (n = 18), with 2 weeks of unloading in a plaster cast followed by 4 weeks of weightbearing in an orthosis. Three-dimensional gait analyses were performed at 8 weeks and 6 months postoperatively to evaluate ankle and knee kinematics and kinetics. Ultrasound imaging was performed to assess tendon length and calf muscle atrophy. At 8 weeks, there were no significant group differences in ankle and knee kinematics and kinetics, while side-to-side differences between injured and uninjured side were present within both groups. At 6 months, the ST group exhibited higher generating ankle power and greater peak moments in ankle and knee compared to the EFM group. In both groups, peak ankle dorsiflexion angle was greater on the injured side compared to the uninjured side. No correlations were found between ankle joint gait deviations and degree of tendon elongation or muscle atrophy. Clinical significance: The accelerated rehabilitation regimen with EFM did not result in a more symmetrical gait pattern. The gait pattern deviations in the ankle joint were not related to the degree of muscle atrophy or tendon elongation.
