AbstractIntroductionThe incidence of Achilles tendon rupture shows a gradually increasing trend, which is mainly managed by minimally invasive treatment due to its advantages, such as low wound infection rate. At present, the firmness of the commonly applied minimally invasive suture method for Achilles tendon remains controversial. Our research group has developed a novel suture method for Achilles tendon, which has achieved favorable clinical outcomes. Therefore, this experiment aimed to explore the optimal approach to repair Achilles tendon rupture through comparing the biomechanical strength of the commonly used Achilles tendon suture methods currently.Materials and methods6 fresh frozen human cadaveric Achilles tendon specimens were sutured by three kinds of technique, and were tested through the cyclical loading after repair.ResultsResults of cyclical loading showed that, the repair using the new technique was stronger after 10 cycles, 1000 cycles, and rupture. Moreover, the new technique had displayed superior anti-deformation strength to that of the Ma-Griffith technique.ConclusionsOur experimental results demonstrate that, the new technique proposed by our research group can attain comparable biomechanical properties to those of the Krachow technique. However, the sample size in this study is small, and further clinical trials are warranted.

Objective: To assess the degree of postoperative satisfaction of patients with acute Achilles tendon rupture who underwent surgical reconstruction by a minimally invasive technique using Tenolig®. Methods: A retrospective observational study was conducted with 18 patients with acute Achilles tendon rupture diagnosed by a positive Thompson test who underwent surgery. Outcomes were assessed using the American  arthopaedic Foot and Ankle Society (AOFAS) score and the Foot Function Index (FFI). Furthermore, quantitative variables were descriptively treated, and patients’ age was correlated with FII and AOFAS score using Spearman’s correlation coefficient at a significance level of 5%. Results: Patients underwent surgery from one to six days after injury and were discharged one day later. Only one patient had a superficial postoperative infection. Patients’ AOFAS scores ranged from 75 to 100 points, and FFI ranged from 0 to 20%. The patient withsuperficial postoperative infection had an AOFAS score and a FFI of 75 points and 20%, respectively. Conclusion: Percutaneous repair of complete Achilles tendon rupture with Tenolig® resulted in high functional scores and a low rate of complications.

Abstract Background Unlike acute Achilles tendon rupture (AATR), neglected Achilles tendon rupture (NATR) requires usually tendon grafting procedures for repair tendon defects caused by removing scar tissue. The conventional open surgery of V-Y tendon plasty and minimally invasive technique with plantar tendon transfer had been described, but the long-term efficacy between the two techniques still needs further certification. Methods Between February 1, 2008, and July 31, 2018. All of 46 patients with neglected Achilles tendon rupture, 25 patients in group A (21 males and 4 females; age, 34.28 ± 6.97 years) underwent the conventional operation of V-Y tendon plasty, and 21 patients in group B (14 males and 7 females; age, 35.29 ± 7.42 years) were treated by the minimally invasive technique. Two years follow-up was performed for the functional recovery with examinations of the Achilles tendon rupture score (ATRS), American Orthopaedic Foot and Ankle Society (AOFAS) Ankle Hind-Foot Scale Score, dorsiflexion, calf circumference, and heel raise test. Results Patient characteristics between the two groups were similar. The functional score of ATRS and AOFAS in Group B was higher than patients in group A at postoperative months 3, 6, and 12, while there is no difference at month 24. In group A, there were three patients exposed to soft tissue infections (two superficial infections and one deep infection) and one case with tendon exposure. In group B, a patient with tendon re-rupture was observed. There was no difference in dorsiflexion and calf circumference at follow-up two years and the much better recovery in heel raise test group B than A. Conclusions Two different techniques produced a significant functional improvement, and return to sports. However, this study demonstrated that the minimally invasive technique was recommended for patients with a tendon defect less than 6 cm and who have an urgent demand to return to the sports.

Objective: Our study compares the functional outcomes of patients who underwent open repair of the Achilles tendon with those of patients treated with the minimally invasive technique using the percutaneous Achilles repair system (PARS) over a 1-year minimum follow-up period and presents the complication rates for the 2 techniques. Methods: Between 2011 and 2016, 31 patients were reviewed; of these, 20 were included in the study (10 PARS X 10 open repair technique). Patients with chronic Achilles tendon rupture, insertional or bilateral, and patients with a history of surgery or previous ankle pathology that could mask functional outcomes were excluded from the study. The open repair technique was performed via a posteromedial incision to the ankle to repair the tendon and was combined with myotendinous transfer of the flexor hallucis longus tendon, which was fixed with a Biotenodesis screw. The minimally invasive technique was performed using the PARS of the company Arthrex through a small transverse incision at the site of the Achilles tendon rupture. Functional outcomes and complications were collected after at least 1 year of follow-up. Results: Both groups had similar American Orthopedic Foot and Ankle Society (AOFAS) scores (PARS: 95.3±5.1, open: 96.5±5.1; p=0.604), demonstrating similar functional outcomes. The PARS group had a higher number of complications than the open repair group (PARS: 20% x open: 10%), but the difference was not significant (p=0.383). Conclusion: For the treatment of acute Achilles tendon injuries, the PARS and open repair techniques had similar functional outcomes after 1 year of follow-up.

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.

Objective The purpose of the study is to evaluate the clinical results and return to sports in patients undergoing reconstruction of the Achilles tendon after minimally invasive reconstruction with semitendinosus tendon graft transfer. Methods Eight patients underwent surgical reconstruction with a minimally invasive technique and tendon graft augmentation with ipsilateral semitendinosus tendon for chronic Achilles tendon rupture (more than 30 days after the injury and a gap of >6 cm). Patients were evaluated at a minimum follow-up of 24 months after the surgery through the American Orthopaedic Foot and Ankle Society (AOFAS), the Achilles Tendon Total Rupture Scores (ATRS), the Endurance test, the calf circumference of the operated limb, and the contralateral and the eventual return to sports activity performed before the trauma. Results The mean age at surgery was 50.5 years. Five men and three women underwent the surgery. The average AOFAS was 92, mean Endurance test was 28.1, and the average ATRS was 87. All patients returned to their daily activities, and six out of eight patients have returned to sports activities prior to the accident (two football players, three runners, one tennis player) at a mean of 7.0 (range: 6.7–7.2) months after the surgery. No patient reported complications or reruptures. Conclusion Our study confirms encouraging results for the treatment of Achilles tendon rupture with a minimally invasive technique with semitendinosus graft augmentation. The technique can be considered safe and allows patients to return to their sports activity. Level of Evidence Level IV, therapeutic case series.

Category: Trauma Introduction/Purpose: Transfer of a flexor hallucis longus (FHL) tendon can not only reconstruct the Achilles tendon but also provide ischemic tendinous tissues with a rich blood supply to enhance wound healing. This retrospective study aims to investigate clinical outcomes in patients who underwent repair of Kuwada grade IV chronic Achilles tendon rupture with long hallucis longus tendons harvested using a minimally invasive technique. Methods: 35 patients who were treated for Kuwada grade IV Achilles tendon injuries from July 2006 to June 2011 were included in this retrospective study. The age ranged between 23 and 71 years. The duration from primary injury to surgery ranged from 29 days to 34 months (mean value, 137.6 days). All 35 patients had difficulties in lifting their calves. 32 were followed up for a mean 32.2 months (range 18-72 months), whereas 3 were lost to follow-up. Magnetic resonance imaging (MRI) showed that the tendon rupture gap ranged from 6.0 to 9.2 cm. Postoperative appearance and function were evaluated by physiotherapists based American Orthopedic Foot and Ankle Society-ankle and hindfoot score (AOFAS-AH), and Leppilahti Achilles tendon ratings. Results: Results were assessed in 32 patients. Except for one patient who suffered complications because of wound disruption 10 days after the operation, all other patients had primary wound healing, with 28 of 32 able to go up on their toes at last follow-up. The AOFAS-AH score was increased from preoperative (51.92 ± 7.08) points to (92.56 ± 6.71) points; Leppilahti Achilles tendon score was increased from preoperative (72.56 ± 7.43) to (92.58 ± 5.1). There were statistically significant differences. The result of the total excellent and good rate was 93.8% (30/32). MRI of Achilles tendon showed even signal without evidence of tear or cystic degeneration. Conclusion: Reconstruction of a chronic Achilles tendon rupture with an FHL tendon harvested using a minimally invasive technique showed good outcomes.

Abstract Background: Subcutaneous, spontaneous, complete ruptures of the Achilles tendon are usually caused indirectly by trauma associated with rapid movement. When minimally invasive Achilles tendon repair is performed, an active rehabilitation protocol can be implemented that allows for fast, measurable progress, reduced tissue atrophy, and an improved range of motion, thereby reducing pain and increasing patients’ overall physical well-being. However, overestimating the effectiveness of rehabilitative interventions can lead to arbitrary advancements in rehabilitation that significantly exceed the permitted levels of daily or professional activity. This issue can lead to various side effects and slow rehabilitation. The aim of the study was to evaluate the influence of adverse effects on objective outcomes after minimally invasive Achilles tendon repair.Methods: The study included 36 individuals with complete Achilles tendon rupture who underwent the percutaneous Ma-Griffith technique. The same rehabilitation protocol was used.Results: Five side effects were identified during rehabilitation: deformation of the repair construct (DRC), irritation of the sural nerve (SNI), morning ankle stiffness (MAS), edema of the soft tissue around the tendon (OST) and suture knots. DRC and MAS were associated with a longer time being required to achieve full ankle range of motion. SNI and OST were associated with a longer time being required to meet the criteria for dynamic training. None of the side effects were related to the isokinetic strength of the ankle plantar and dorsiflexors.Conclusions: The incidence of the assessed side effects in the postoperative period is not related to the type of activity, whether it is professional or amateur. Among the identified side effects, deformation of the regenerated shape of the heel tendon and MAS cause a delay in the recovery of full ankle range of motion. Calf nerve irritation and soft tissue swelling increase the time it takes to meet the criteria for starting dynamic training.Trial registration:The study was approved by the ethics committee of the Academy of Physical Education in Katowice (no. 13/2007)
