Return to Sport and Patient Satisfaction at 5-Year Follow-up After Nonoperative Treatment for Acute Achilles Tendon Rupture

Validation of a Composite Outcome Score for Assessing Return to Sports After Achilles Tendon Repair

BACKGROUND

The Ankle-GO is a composite outcome score based on 4 functional tests and 2 patient-reported outcome measures. It was initially described and validated for its ability to predict return to sports (RTS) at the same level of play after lateral ankle sprains.

PURPOSE/HYPOTHESIS

The main aim of this study was to assess the psychometric properties of the Ankle-GO in patients after Achilles tendon repair. The second objective was to evaluate its ability to predict RTS at the same level of play. It was hypothesized that this composite outcome score is a valid and reliable tool that is able to discriminate and predict the level of RTS at 9 months after Achilles tendon repair.

STUDY DESIGN

Case-control study; Level of evidence, 3.

METHODS

This was a prospective multicenter study. Patients who were active in sports and underwent primary acute Achilles tendon repair between April 2021 and December 2022 were included. A control group comprising 30 participants with no history of lower limb injuries was also evaluated. After standard rehabilitation for the first 2 months, the Ankle-GO was administered at 6 and 9 months after repair by the same experienced physical therapist. During testing, the patients were asked whether they were able to practice their main sport again and, if so, whether at the same or a lower level of play. A comparison between control participants and patients at 9 months after surgery was performed.

RESULTS

A total of 50 patients (24 women and 26 men), with a mean age of 38.3 ± 10.1 years, were included. No patients were lost to follow-up at 9 months. The Ankle-GO score at 6 months was 10.7 ± 4.8. At 9 months, the score had risen by 4.8 points. All participants scored above the minimum threshold. The minimum score achieved was 3 points (n = 5 [10%]). Only 1 patient (2%) obtained the maximum score (25 points). There was a significant difference in the Ankle-GO score between patients at 6 and 9 months and between control participants and patients at 9 months after Achilles tendon repair. Of the 50 patients included in the study, 14 (28%) returned to their preinjury level of sport at 9 months. The ability of the Ankle-GO score at 6 months to predict RTS at the preinjury level at 9 months was good (area under the curve = 0.71 [95% CI, 0.56-0.85]; P < .01). A Youden index of 0.42 was observed for a cut-off score of 8 points, which corresponds to a sensitivity of 81.8% and a specificity of 41.2%.

CONCLUSION

The Ankle-GO is a valid tool to evaluate and discriminate patients during the RTS continuum after Achilles tendon repair and to predict RTS at the same level at 9 months after surgery. This composite outcome score assesses ankle function and the patient's psychological readiness to avoid premature RTS and worsening of the injury. Further studies are needed to assess its value in identifying and predicting patients at risk of a recurrence.

Open vs. Percutaneous Achilles Tendon Repair: Experience of Single Orthopedic Institute with Long-Term Follow-Up

Background and Objectives: There are numerous techniques for the surgical treatment of Achilles tendon lesions described in the literature, and it is possible to distinguish repair techniques as either open surgery or percutaneous repair techniques. Both approaches have advantages and disadvantages. With this retrospective study, we aim to analyze the incidence of re-ruptures and other complications, return to sport and overall quality of life at a long-term follow-up in the treatment of acute ATRs, comparing the results of percutaneous repair with those of open repair. Materials and Methods: This is a retrospective study on a consecutive series of patients with complete tear of the AT who were managed through a surgical approach by the Operative Unit of Orthopaedics and Traumatology of Sant'Anna University Hospital (Ferrara, Emilia-Romagna, Italy) between April 2014 and December 2021. Patients were treated with a percutaneous or an open technique according to the surgeon's preference without randomization. Results: We considered 155 patients who met the established inclusion criteria. Of these, 103 (66.45%) patients underwent percutaneous treatment with the Tenolig® system, and 52 (33.55%) underwent open surgery, with an average ATRS in the first group of 92.5 compared to an average ATRS value of 82 in patients treated with the open technique. Conclusions: In our experience, following overlapping rehabilitation protocols in all patients included, we observed that the Tenolig® repair system led to a better ATRS at long-term follow-up, with comparable complication rates to open surgery.

Establishment of the Patient Acceptable Symptom State (PASS) for the Achilles Tendon Total Rupture Score in a Swedish Population

Background

As the use of patient-reported outcome measures (PROMs) is increasing in orthopaedic research, there is also a growing need for a standardized interpretation of these scores, such as the Patient Acceptable Symptom State (PASS), defined as the value beyond which patients consider themselves well. The Achilles tendon Total Rupture Score (ATRS) is the only PROM specific for Achilles tendon ruptures.

Purpose

To establish the PASS for the ATRS in a Swedish population.

Study Design

Cross-sectional study; Level of evidence, 3.

Methods

Patients treated for an acute Achilles tendon rupture at a single institution in Sweden (injured between July 1, 2018, and December 31, 2020) were asked to participate in this study. The patients completed a questionnaire consisting of the ATRS and an anchor question: "How satisfied are you with the result of your treatment?" Receiver operating characteristic curve analysis was performed to calculate the PASS threshold for a positive response to the anchor question.

Results

Of 516 eligible patients, 316 (61%) were included. The time from injury to completion of the questionnaire ranged from 12 to 27 months. The PASS threshold for the ATRS was found to be 75. The median ATRS of all patients was 80; 66% of patients reached an ATRS ≥75. Overall, 79% of patients were satisfied with the results of their treatment.

Conclusion

The estimated PASS for the ATRS was 75 in the general Swedish population at 12 to 27 months after an acute Achilles tendon rupture.

Tendon Elongation and Function After Delayed or Standard Loading of Surgically Repaired Achilles Tendon Ruptures: A Randomized Controlled Trial

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.

Current Concepts in Achilles Tendon Ruptures

The Achilles tendon has a high incidence of ruptures often occurring in weekend warriors and the aging population. Based on anatomic studies of the Achilles tendon, ruptures are commonly found in the watershed area proximal to the insertion site. Traditionally, treatment options included conservative therapy with immobilization and a prolonged non-weight-bearing phase versus surgical treatment. Surgical treatment can vary between open, minimally invasive, or percutaneous approaches. In more recent years, early functional rehabilitation with or without surgery has shown to have successful results.

Qualitative Research in Return to Sport: a Current Review of the Literature

PURPOSE OF REVIEW

Return to sport (RTS) is an important metric tied to patient satisfaction after receiving treatment for a sports-related injury. Recently, there has been an explosion of literature on RTS; yet a comprehensive review encompassing multiple injuries does not exist. Furthermore, RTS has historically been defined by quantitative measures that assess strength, function, and pain but little consideration has been given to psychologic factors nor has there been an open-ended forum for athletes to share with health care providers which factors they feel are most influential for RTS. This review also serves to heighten surgeons' awareness of underlying psychologic/psychosocial factors affecting RTS.

RECENT FINDINGS

Qualitative studies which employ open-ended questioning of athletes who have undergone surgical management of superior labral anterior-posterior (SLAP) tears, shoulder instability, ulnar collateral ligament (UCL) rupture, femoral acetabular impingement (FAI), and anterior cruciate ligament (ACL) tear demonstrate that fear of reinjury, lack of social support, and unrealistic expectations are all barriers to RTS. Qualitative studies give health care providers unique insight into the perspectives of their patients so that unmet postoperative needs can be addressed to facilitate RTS. Sports psychologists, coaches, athletic trainers, and physical therapists should create a positive environment to address these needs and provide optimal, holistic care to return athletes to the field safely. Though time consuming, further qualitative research is necessary to understand the unique factors affecting RTS in athletes.

Factors That Affect Return to Sports After an Achilles Tendon Rupture: A Qualitative Content Analysis

Background

Achilles tendon rupture is common among physically active individuals, yet a high percentage fail to return to their former activity after the injury. Quantifiable factors such as type of treatment, hours of rehabilitation, and age have not been associated with return-to-play rates. A factor that influences recovery is the participant's experience before and throughout the rehabilitation process, which can be explored using a qualitative content analysis.

Purpose

To explore and describe what influences the participant to return to physical activity after an Achilles tendon rupture.

Study Design

Cross-sectional study; Level of evidence, 3.

Methods

Twenty participants (14 men; mean age, 46 years) were interviewed as part of this study. All participants had ruptured their Achilles tendon 4 to 6 years before the interviews. From the interviews, codes were extracted that evolved into 19 subcategories, 6 categories, and 1 theme.

Results

The overarching theme that emerged was "Help me and then I can fix this." The 6 categories were (1) one's own drive to succeed, (2) having a supportive social network, (3) trusting the support from the health and social systems, (4) receiving and adapting information from others drives persistence in returning to activity, (5) impact of the injury on psychological factors; and (6) influence of physiological aspects.

Conclusion

To be able to recover properly from an Achilles tendon rupture and return to activity, the study participants described the importance of obtaining the support needed to be able to gain optimal rehabilitation. In the participants' opinion, for a greater chance of successful treatment and rehabilitation, it was vital to be provided with good support.

Surgical versus nonsurgical treatment of acute Achilles ruptures in the high demand patient: Using decision analysis to help clinical decisions

BACKGROUND

Recent literature suggests that functional treatment of acute non-insertional Achilles tendon ruptures yields outcomes (re-rupture and function) similar to those of surgery, but does not address the unique issues in treating high performance athletes or other high demand patients.

METHODS

Decision analysis was used to develop an estimate of outcome utility for both types of treatment using published Costs and Quality-Adjusted Life Years (QALYs) values. The expected value for either treatment was then calculated for high, intermediate, and normal demand patients, using the specific functional needs of the patients.

RESULTS

Nonoperative treatment is the preferred management for normal demand patients, while high and intermediate demand patients are more likely to experience better expected functional outcomes from surgery.

CONCLUSION

The combination of a decision analysis and expected value analysis provides evidence-based support for the existing intuitive recommendations that favor surgical treatment in elite athletes and other high demand patients.

Achilles Tendon Ruptures and Repair in Athletes-a Review of Sports-Related Achilles Injuries and Return to Play

PURPOSE OF REVIEW

Achilles tendon ruptures (ATR) are detrimental to sports performance, and optimal treatment strategy and guidelines on return to play (RTP) remain controversial. This current review investigates the recent literature surrounding nonoperative versus operative management of ATR, clinical outcomes, and operative techniques to allow the athlete a successful return to their respective sport.

RECENT FINDINGS

The Achilles tendon (AT) is crucial to the athlete, as it is essential for explosive activities such as running and jumping. Athletes that sustain an ATR play in fewer games and perform at a lower level of play compared to age-matched controls. Recent studies also theorize that ATRs occur due to elongation of the tendon with fatigue failure. Biomechanical studies have focused on comparing modes of fixation under dynamic loading to recreate this mechanism. ATRs can be career-ending injuries. Fortunately, the recent incorporation of early weight-bearing and functional rehabilitation programming for non-operative and operative patients alike proves to be beneficial. Especially for those treated nonoperatively, with the incorporation of functional rehabilitation, the risk of re-rupture among non-operative patients is beginning to approach the historical lower risk of re-rupture observed among patients treated operatively. Despite this progress in decreasing risk of re-rupture particularly among non-operative patients, operative managements are associated with unique benefits that may be of particular interest for athletes and active individuals. Recent studies demonstrate that operative intervention improves strength and functional outcomes with more efficacy compared to nonoperative management with rehabilitation. The current literature supports operative intervention in elite athletes to improve performance and shorten the duration to RTP. However, we acknowledge that surgical intervention does have inherent risks. Ultimately, most if not all young and/or high-level athletes with an ATR benefit from surgical repair, but it is crucial to take a stepwise algorithmic approach and consider other factors, which may lead towards nonoperative intervention. These factors include age, chronicity of injury, gap of ATR, social factors, and medical history amongst others in this review.

Supervised Physiotherapy Improves Three-Dimensional (3D) Gait Parameters in Patients after Surgical Suturing of the Achilles Tendon Using an Open Method (SSATOM)

BACKGROUND

The aim of this study was to assess the effectiveness of 38 supervised postoperative physiotherapy (SVPh) visits conducted between 1 and 20 weeks after SSATOM on the values of 3D gait parameters measured at 10 and 20 weeks after surgery.

MATERIAL

Group I comprised male patients (n = 22) after SSATOM (SVPh x = 38 visits) and Group II comprised male patients (n = 22) from the control group.

METHODS

A non-randomized, open-label, controlled clinical trial was performed in the two groups to obtain the following values: Step length (cm), stride length (cm), step width (cm), next stance phase (%), swing phase (%), double support (%), gait velocity (m/s), and walking frequency (step/min). The measurements were carried out using the BTS SMART system (Italy).

RESULTS

Orthopedic examination showed no pain, a negative result of Thompson and Matles tests, and proper healing of Achilles tendon (ultrasound image). In Group I, between 10 and 20 weeks after SSATOM, there was a statistically significant improvement in all tested gait parameter values (p ≤ 0.001 to 0.009).

CONCLUSIONS

Conducting 38 SVPh visits significantly improved the values of the analyzed kinematic and spatiotemporal gait parameters in patients in the twentieth week after SSATOM, which were mostly close to the non-operated side and the results of the control group. However, the gait speed and stride length were not close to the results of the control group.

Estimation of Patient Acceptable Symptom State (PASS) and Treatment Failure (TF) Threshold Values for the Achilles Tendon Total Rupture Score (ATRS) at 6 Months, 1 Year, and 2 Years After Acute Achilles Tendon Rupture

Interpretation of the Achilles tendon Total Rupture Score (ATRS) is challenging because limited knowledge exists about at which score the patients consider the outcome of treatment as satisfactory. The aims of the study were (1) to describe the proportion of patients who find their symptom levels to be satisfactory, to reflect treatment failure or neither after acute Achilles tendon rupture (ATR), and (2) to estimate the Patient Acceptable Symptom State (PASS) and the Treatment Failure (TF) threshold values for the ATRS at 6 months, 1 year, and 2 years after ATR. The study was based on data extracted from the nationwide Danish Achilles tendon Database which includes patients treated operatively or nonoperatively after ATR. The PASS and TF threshold values for ATRS were estimated using the adjusted predictive modeling method. One hundred and sixty-six patients were included at 6 months, 248 patients at 1 year, and 287 patients at 2 years after ATR. The proportion of patients who considered their symptom level to be satisfactory was 61% at 6 months, 50% at 1 year, and 66% at 2 years, while 5% at 6 months, 11% at 1 year, and 10% at 2 years considered their symptom level to reflect treatment failure. The PASS threshold value for ATRS (95% confidence interval) was 49 (46-52) at 6 months, 57 (54-60) at 1 year, and 52 (49-55) at 2 years. The TF threshold value for ATRS was 30 (23-36) at 6 months, 33 (26-40) at 1 year, and 35 (29-39) at 2 years. The calculated PASS and TF threshold values can help interpret the outcome of ATR when measured with the ATRS. About 50% to 66% of the patients had a satisfactory symptom level after ATR.

Return-to-play and performance after operative treatment of Achilles tendon rupture in elite male athletes: a scoping review

OBJECTIVE

To examine the current evidence regarding return-to-play (RTP) and performance after Achilles tendon rupture in elite athletes treated with operative intervention.

DESIGN

Scoping review.

DATA SOURCES

Published sources identified through a PubMed search of elite athletes, defined as professional or division one collegiate athletes in baseball, basketball, American football or soccer.

METHODS

Our search yielded a total of 2402 studies, with 13 studies fulfilling the study criteria of reporting elite athletes with objective measures of their athletic performance. A total of 709 elite athletes were included from the NBA, NFL, Major League Baseball (MLB), National Collegiate Athletic Association (NCAA) football and professional soccer.

RESULTS AND DISCUSSION

Overall, 61%-100% of elite male athletes RTP after Achilles tendon rupture and operative repair. NBA players had inferior performance compared with their preoperative status as well as controls of non-injured players. Studies did not show significantly different performance after Achilles injury for MLB players. Professional soccer, NFL and NCAA football studies reported varying performance after injury.

CONCLUSIONS

Evidence suggests that sports with explosive plantarflexion demands, such as basketball, may be associated with a greater decrease in performance despite operative intervention after Achilles rupture.

The dispersion of viscoelastic properties of fascicle bundles within the tendon results from the presence of interfascicular matrix and flow of body fluids

In this work, we investigate differences in the mechanical and structural properties of tendon fascicle bundles dissected from different areas of bovine tendons. The properties of tendon fascicle bundles were investigated by means of uniaxial tests with relaxation periods and hysteresis, dynamic mechanical analysis (DMA), as well as magnetic resonance imaging (MRI). Uniaxial tests with relaxation periods revealed greater elastic modulus, hysteresis, as well as stress drop during the relaxation of samples dissected from the posterior side of the tendon. However, the normalized stress relaxation curves did not show a statistically significant difference in the stress drop between specimens cut from different zones or between different strain levels. Using dynamic mechanical analysis, we found that fascicle bundles dissected from the anterior side of the tendon had lower storage and loss moduli, which could result from altered fluid flow within the interfascicular matrix (IFM). The lower water content, diffusivity, and higher fractional anisotropy of the posterior part of the tendon, as observed using MRI, indicates a different structure of the IFM, which controls the flow of fluids within the tendon. Our results show that the viscoelastic response to dynamic loading is correlated with fluid flow within the IFM, which was confirmed during analysis of the MRI results. In contrast to this, the long-term relaxation of tendon fascicle bundles is controlled by viscoplasticity of the IFM and depends on the spatial distribution of the matrix within the tendon. Comparison of results from tensile tests, DMA, and MRI gives new insight into tendon mechanics and the role of the IFM. These findings may be useful in improving the diagnosis of tendon injury and effectiveness of medical treatments for tendinopathies.

Long Term Clinical-Functional and Ultrasound Outcomes in Recreational Athletes after Achilles Tendon Rupture: Ma and Griffith versus Tenolig

Background and Objectives: The purpose of this retrospective study was to compare the long-term clinical-functional and ultrasound outcomes of recreational athletes treated with two percutaneous techniques: Ma and Griffith (M&G) and the Tenolig technique (TT). Materials and Methods: recreational athletes, between 18 and 50 years of age, affected by acute Achilles tendon rupture (AATR), treated by M&G or Tenolig techniques were recruited. Clinical-functional outcomes were evaluated using Achilles Tendon Rupture Score (ATRS), AOFAS Ankle-Hindfoot score, VAS (for pain and satisfaction) questionnaires, and ultrasound analysis (focal thickening, hypoechoic areas, presence of calcifications, tendinitis and alteration of normal fibrillar architecture). Results: 90 patients were included: 50 treated by M&G, 40 by TT. In all, 90% of patients resumed sports activities, with pre-injury levels in 56% of cases after M&G and in 60% after TT. In the M&G group, the averages of the questionnaires were ATRS 90.70 points, AOFAS 91.03, VAS satisfaction 7.08, and VAS pain 1.58. In the TT group: ATRS 90.38 points, AOFAS 90.28, VAS satisfaction 7.76, and VAS pain 1.34. The TT group showed a significantly higher satisfaction and return to sport activities within a shorter time. In the M&G group, ultrasound check showed a significantly greater incidence of thickening and an alteration of fibrillar architecture in the treated tendon. Three infections were reported, including one deep after M&G, two superficial in the TT group, and two re-ruptures in the Tenolig group following a further trauma. Conclusions: At long-term follow-up, M&G and TT are both valid techniques for the treatment of AATRs in recreational athletes, achieving comparable clinical-functional results. However, TT seems to have a higher patient satisfaction rate, a faster return to sports and physical activities, and fewer ultrasound signs of tendinitis. Finally, the cost of the device makes this technique more expensive.

Augmented Repair of Acute Total Achilles Tendon Rupture With Peroneus Brevis Tendon Transfer Using Oblique Transosseous Calcaneal Tunnel: A Prospective Case Series

Acute Achilles tendon rupture is one of the most common tendon injuries. This prospective study aimed to evaluate the functional outcomes of augmented repair of acute Achilles tendon rupture with peroneus brevis tendon transfer and fixation to an oblique calcaneal transosseous tunnel. Functional evaluation was performed using the American Orthopaedic Foot & Ankle Society (AOFAS) score and Achilles Tendon Total Rupture Score (ATRS). Postoperative complications were recorded. This study included 33 males and 9 females, with a mean age of 26.1 ± 4.2 years. The Achilles tendon ruptures were right in 24 patients and left in 18 patients. The cause of rupture was sports injuries in all patients. The mean distance from the calcaneal insertion to the tear site was 4.4 ± 1.3 cm. The mean time from injury to surgery was 2.4 ± 1.6 days. The mean follow-up time was 40.3 ± 4.9 months. The mean AOFAS and ATRS scores were 99.3 ± 1.2 and 95.9 ± 1.9, respectively, at 12 months of follow-up. The mean time to return to work was 12.1 ± 1.2 weeks. The mean time to return to light sports activities was 16.1 ± 1.8 weeks postoperatively. None of the patients developed re-rupture. Augmented repair of acute Achilles tendon ruptures with peroneus brevis tendon transfer is a robust repair with excellent functional outcomes and early weight-bearing and return to sports activities.

Rehabilitation After Surgical Repair of Acute Achilles Tendon Rupture: Functional Outcome With a Minimum Follow-Up of 6 Months

The best treatment and rehabilitation of Achilles tendon ruptures remains controversial. Current literature focuses mainly on objective outcomes despite possible incongruity with patient-reported functional outcomes. Therefore, we aimed to identify the course of patient-reported symptoms, function and quality of life during the early rehabilitation period. In this prospective cohort study, 33 patients with an acute Achilles tendon rupture treated with minimally invasive tendon repair were included in this study. They were followed up at 6, 12, 18 and 24 weeks after surgery with the Foot and Ankle Outcome Score questionnaire. At 6 weeks, patient-reported outcomes were poor regarding quality of life and sports. They however were quite high in the domains activities of daily living, symptoms and pain. All scores improved over the course of 6 months (symptoms (p = .03), activities of daily living (p = .001), sports (p = .002) and quality of life (p = .001). Pain did not improve significantly (p = .12), but patients had good pain scores from the start. There were no significant differences between patients with or without physical therapy. There were 3 minor complications and no re-ruptures in this cohort. In conclusion, patient-reported outcomes improve significantly during the first 6 months after surgery, except for pain. Scores for sports and quality of life remain suboptimal.

Six out of ten patients with sinus tarsi syndrome returned to pre-injury type of sport after subtalar arthroscopy

PURPOSE

The purpose of this study was to determine multiple return to sport rates, long-term clinical outcomes and safety for subtalar arthroscopy for sinus tarsi syndrome.

METHODS

Subtalar arthroscopies performed for sinus tarsi syndrome between 2013 and 2018 were analyzed. Twenty-two patients were assessed (median age: 28 (IQR 20-40), median follow-up 60 months (IQR 42-76). All patients were active in sports prior to the injury. The primary outcome was the return to pre-injury type of sport rate. Secondary outcomes were time and rate of return to any type of sports, return to performance and to improved performance. Clinical outcomes consisted of Numerous Rating Scale of pain, Foot and Ankle Outcome Score, 36-item Short Form Survey and complications and re-operations.

RESULTS

Fifty-five percent of the patients returned to their preoperative type of sport at a median time of 23 weeks post-operatively (IQR 9.0-49), 95% of the patients returned to any type and level sport at a median time of 12 weeks post-operatively (IQR 4.0-39), 18% returned to their preoperative performance level at a median time of 25 weeks post-operatively (IQR 8.0-46) and 5% returned to improved performance postoperatively at 28 weeks postoperatively (one patient). Median NRS in rest was 1.0 (IQR 0.0-4.0), 2.0 during walking (IQR 0.0-5.3) during walking, 3.0 during running (IQR 1.0-8.0) and 2.0 during stair-climbing (IQR 0.0-4.5). The summarized FAOS score was 62 (IQR 50-90). The median SF-36 PCSS and the MCSS were 46 (IQR 41-54) and 55 (IQR 49-58), respectively. No complications and one re-do subtalar arthroscopy were reported.

CONCLUSION

Six out of ten patients with sinus tarsi syndrome returned to their pre-injury type of sport after being treated with a subtalar arthroscopy. Subtalar arthroscopy yields effective outcomes at long-term follow-up concerning patient-reported outcome measures in athletic population, with favorable return to sport level, return to sport time, clinical outcomes and safety outcome measures.

Achilles Tendon Rupture: Mechanisms of Injury, Principles of Rehabilitation and Return to Play

The Achilles tendon is the thickest, strongest and largest tendon in the human body, but despite its size and tensile strength, it frequently gets injured. Achilles tendon ruptures (ATRs) mainly occur during sports activities, and their incidence has increased over the last few decades. Achilles tendon tears necessitate a prolonged recovery time, sometimes leaving long-term functional limitations. Treatment options include conservative treatment and surgical repair. There is no consensus on which is the best treatment for ATRs, and their management is still controversial. Limited scientific evidence is available for optimized rehabilitation regimen and on the course of recovery after ATRs. Furthermore, there are no universally accepted outcomes regarding the return to play (RTP) process. Therefore, the aim of this narrative review is to give an insight into the mechanism of injuries of an ATR, related principles of rehabilitation, and RTP.

Achilles Tendinosis Injuries-Tendinosis to Rupture (Getting the Athlete Back to Play)

Recreational athletes are susceptible to experiencing pain in the Achilles tendon, affecting their ability to complete daily activities. Achilles tendinosis is a degenerative process of the tendon without histologic or clinical signs of intratendinous inflammation, which can be categorized by location into insertional and noninsertional tendinosis. This condition is one that can be treated conservatively with great success or surgically for refractory cases. Currently, there is a lack of consensus regarding the best treatment options. This review aims to explore both conservative and operative treatment options for Achilles tendinopathy and Achilles tendon rupture.
