Achilles tendon reattachment after surgical treatment of insertional tendinosis using the suture bridge technique: a case series

Anterior Cruciate Ligament Reconstruction with Internal Brace Augmentation Results in Fewer Reruptures Compared to Reconstruction without Augmentation

Objective  To compare the clinical outcomes of anterior cruciate ligament (ACL) reconstruction using autografts with and without internal brace augmentation. Methods  Data from patients who underwent ACL reconstruction with hamstring and quadriceps tendon autografts, with a minimum follow-up of one year, with or without internal brace augmentation were collected prospectively analyzed retrospectively. The Lysholm and Tegner functional scores were collected before and after surgery, as well as data on postoperative complications. For the comparison of means of the two groups, we used the Student t test or the Mann-Whitney non-parametric test, when the assumption of normality of the data was rejected. Results  In total, 55 patients underwent ACL reconstruction with internal brace augmentation and another 55 patients underwent ACL reconstruction without internal brace augmentation. The patients were aged between 16 and 63 years (mean of 32.7 ± 11.4 years). A total of 62 patients (56.4%) underwent ACL reconstruction with hamstring graft, and 19 patients (17.3%), with quadriceps tendon graft, with a diameter variation of 7 mm to 11 mm (mean of 8.95 ± 0.83 mm). The postoperative scores did not differ between the groups ( p  > 0.05). Regarding the group submitted to ACL reconstruction with internal brace augmentation, 4 patients had complications: @ cases of arthrofibrosis, 2 (3.7%); 1 case of rerupture (1.8%); and 1 case of thrombosis (1.8%). In the group submitted to ACL reconstruction without augmentation, 7 patients manifested complications: 2 cases of arthrofibrosis (3.9%); 4 cases of rerupture (7.3%); and 1 case of infection (2%). Conclusion  The results of the present study show that fewer cases of ACL rerupture were observed after reconstruction with internal brace augmentation when compared with ACL reconstruction without augmentation, although no differences in functional scores were found.

Endoscopic calcaneal SpeedBridge technique: Decreased postoperative complication rate in insertional achilles tendinopathy

BACKGROUND

An endoscopic calcaneal SpeedBridge technique was described recently. The primary objective of this study was to report the postoperative complications seen with calcaneal SpeedBridge repair. The secondary objective was to report short- and medium-term functional outcomes.

HYPOTHESIS

Postoperative complications are less common with endoscopic vs. open SpeedBridge suturing.

MATERIAL AND METHODS

The endoscopic SpeedBridge technique was used in 9 patients who had insertional Achilles tendinopathy refractory to conservative management. The patients were evaluated at least 24 months after the procedure. Infectious and wound-healing complications were recorded. Visual analogue scale (VAS) scores for pain and patient satisfaction, shoeing difficulties, the European Foot and Ankle Society (EFAS) score, and the Victorian Institute of Sport Assessment-Achilles (VISA-A) score were assessed.

RESULTS

During the mean follow-up of 25.3 months, no complications were recorded. The EFAS and VISA-A scores were 37/40 and 91/100, respectively. The mean VAS scores for pain and satisfaction were 1.7/10 and 9.3/10, respectively. No patients reported shoeing difficulties.

CONCLUSION

Endoscopic calcaneal SpeedBridge suturing is associated with a lower complication rate compared to the open variant. Clinical outcomes are highly satisfactory in the short and middle terms.

Single-Row Repair Versus Double-Row Repair in the Surgical Management of Achilles Insertional Tendinopathy: A Systematic Review

Background

Approximately 6% of people will report Achilles tendon pain during their lifetime, and one-third of these individuals will have Achilles insertional tendinopathy (AIT). For patients who have failed conservative treatment, surgical repair is performed. Achilles tendon repair can occur through various techniques, including a single-row or double-row repair.

Purpose

To determine if there are significant advantages to double-row repair over single-row repair with respect to biomechanical and clinical outcomes.

Study design

Systematic review; Level of evidence, 3.

Methods

A systematic review of the literature was conducted in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. An electronic search of the EMBASE and PubMed databases was performed for all studies related to surgical treatment of AIT, which yielded 1431 unique results. These included both biomechanical and clinical studies. Clinical studies in which patients were not diagnosed with AIT, underwent surgery for repair of acute Achilles tendon rupture, or studies that included additional procedures such as a concomitant flexor hallucis longus transfer were excluded. Eligible studies were independently screened by 2 reviewers. A risk-of-bias assessment was conducted using the Cochrane Risk Of Bias In Non-randomized Studies-of Interventions and risk-of-bias tool for randomized trials tools.

Results

A total of 23 studies were included, 4 of which were biomechanical studies and 19 were clinical studies. Biomechanical comparison found that there was a significant advantage to using double-row versus single-row fixation with respect to load at yield (354.7 N vs 198.7 N; P = .01) and mean peak load (433.9 N vs 212 N; P = .042). There was no significant difference between double-row and single-row repair with respect to load to failure. Significant heterogeneity of the studies did not allow for a statistical comparison of the clinical outcomes between double-row and single-row repairs.

Conclusion

Although biomechanical studies favor double-row repair for AIT, the current data available on the clinical outcomes are not sufficient to determine if there is a clinical advantage of double-row repair. Larger, prospective randomized controlled trials utilizing validated outcome measures are needed to further elucidate whether the biomechanical advantages associated with double-row repair also translate into improved patient-reported outcomes.

Calcaneal tuberosity avulsion fractures - A review

Calcaneal tuberosity avulsion fracture, an extra-articular injury, is a rare fracture caused internally by Achilles tendon driven following intense contraction of gastrocnemius-soleus complex, and externally by low-energy (possibly high-energy). Moreover, the risk of injuries of the skin and Achilles tendon around calcaneal tuberosity is closely related to Lee classification and Carnero-Martín de Soto Classification of calcaneal tuberosity avulsion fracture. Although the diagnosis confirmed by X-ray, digital imaging and computed tomography (CT), magnetic resonance imaging (MRI) should also be used to evaluate soft tissue. In recent years, the understanding of this fracture has witnessed the development of different internal fixation devices and surgical procedures. These advances have been further elaborated scientifically in terms of their ability to provide stable fracture reduction ad resistance to Achilles tendon forces. In order to obtain a comprehensive knowledge of the disease, this article reviewed the new understanding of the anatomy, typing, risk factors, and treatment modalities of calcaneal tuberosity avulsion fracture in recent years.

No Loss of Strength After Insertional Achilles Tendon Reconstruction With Single-Anchor or Double-Row Repair

Many different types of surgical repair for insertional Achilles tendinosis have been described. Strength after surgery is an essential factor for patient function and satisfaction. A retrospective series of patients that underwent surgery for insertional Achilles tendon surgery were contacted to come in for prospective strength testing, with the tester blinded to the type of surgery performed. Thirty-seven patients came in for testing, 24 with a single-anchor repair and 13 with a double-row repair. Strength of plantarflexion was tested at 60°/s and 120°/s and was compared. First each operative leg was compared to the nonoperative leg as a control. Then the percentage change, or symmetry, from the control leg to the operative leg was compared between those with a single-anchor and double-row repair. Satisfaction was also assessed with a simple questionnaire and compared the types of repair. The results demonstrated there was no statistically significant change in strength after surgery compared to the nonoperative leg, and there was no difference in limb symmetry between types of repair. Similarly, there was no difference between the groups in satisfaction. Our study showed that there is, on average, no loss of strength after insertional Achilles tendon surgery at an average follow-up of nearly 2 years, regardless of type of repair.

The Addition of a Krackow Rip Stop Suture Augment After Achilles Tendon Debridement for Insertional Achilles Tendinopathy: A Biomechanical Study

BACKGROUND

In the operative treatment of insertional Achilles tendinopathy, the Achilles tendon is often released from its insertion to allow for adequate debridement of pathologic tissue. The use of a double row suture anchor construct has become increasingly favorable among surgeons after Achilles tendon debridement. This study hypothesized that the addition of a Krackow rip stop suture augment to the double row suture anchor construct would increase the repair's maximum load to failure. A biomechanically stronger repair would potentially decrease the risk of catastrophic failure with early weight-bearing or accidental forced dorsiflexion after operative management for insertional Achilles tendinopathy.

METHODS

Fourteen cadaveric specimens were used to compare the 2 repair techniques. Achilles tendons were debrided and repaired using either a double row suture anchor with and without the additional Krackow rip stop suture augment. The 2 repair techniques were compared using an axial-torsion testing system to measure average load to failure.

RESULTS

The average load to failure for the double row suture anchor repair alone was 152.00 N. The average load to failure for the tendons with the double row suture anchor with the Krackow rip stop augment was 383.08 N. An independent-samples Mann-Whitney U-test was conducted and the suture anchor plus Krackow augment group had a significantly higher load to failure (P = .011, Mann-Whitney U = 5.00, n1 = n2 = 7, P < .05, 2-tailed).

CONCLUSION

This study confirmed that the addition of a Krakow rip stop augment to the double row suture anchor is able to increase the maximum load to failure when compared to the double row suture anchor alone. These results suggest the potential of this added technique to decrease the risk of catastrophic failure.

Platelet-rich plasma in the pathologic processes of tendinopathy: a review of basic science studies

Tendinopathy is a medical condition that includes a spectrum of inflammatory and degenerative tendon changes caused by traumatic or overuse injuries. The pathological mechanism of tendinopathy has not been well defined, and no ideal treatment is currently available. Platelet-rich plasma (PRP) is an autologous whole blood derivative containing a variety of cytokines and other protein components. Various basic studies have found that PRP has the therapeutic potential to promote cell proliferation and differentiation, regulate angiogenesis, increase extracellular matrix synthesis, and modulate inflammation in degenerative tendons. Therefore, PRP has been widely used as a promising therapeutic agent for tendinopathy. However, controversies exist over the optimal treatment regimen and efficacy of PRP for tendinopathy. This review focuses on the specific molecular and cellular mechanisms by which PRP manipulates tendon healing to better understand how PRP affects tendinopathy and explore the reason for the differences in clinical trial outcomes. This article has also pointed out the future direction of basic research and clinical application of PRP in the treatment of tendinopathy, which will play a guiding role in the design of PRP treatment protocols for tendinopathy.

Retrospective Comparison of Isolated Haglund's Deformity Surgery Versus Combined With Gastrocnemius Recession

Insertional Achilles tendonitis is a common pathology treated by foot and ankle surgeons that may require surgical intervention. Literature has shown good outcomes following detachment and reattachment of the Achilles for removal of the exostosis. However, there is minimal literature showing the impact of adding a gastrocnemius recession to the Haglund's resection. The goal of the present study was to retrospectively review the outcomes of an isolated Haglund's resection versus a Haglund's resection combined with a gastrocnemius recession. A retrospective chart review of 54 operative extremities was performed: 29 with isolated Haglund's resection and 25 with a Strayer gastrocnemius recession. We found similar decreases in pain between the 2 groups, 6.1 to 1.5 and 6.8 to 1.8 in the isolated Haglund's and Strayer's group, respectively. We found decreased postoperative Achilles rupture and reoperation rates in the Strayer group but this did not reach statistical significance. We found a statistically significant decreased rate of wound healing complications in the Strayer group, 4% in the Strayer group and 24% in the isolated procedure. In conclusion, adding a Strayer to a Haglund's resection was found to have a statistically significant decrease in wound complications. We recommend future randomized controlled studies to compare the use of a Strayer procedure on postoperative complications.

Treatment of Calcific Insertional Achilles Tendinopathy: Knotless Internal Brace versus Knot-Tying Suture Bridge

Background: This study aimed to compare the knotless internal brace technique and the knot-tying suture bridge technique via the medial approach in the treatment of calcific Achilles tendinopathy. Methods: The clinical data of 25 cases of calcific Achilles tendinopathy in which nonoperative treatments had failed were retrospectively collected. All the patients received Achilles tendon debridement and Haglund deformity excision through a medial approach, followed by repair using the knotless internal brace technique or the knot-tying suture bridge technique. Pain was evaluated by using the visual analog scale (VAS). The American Orthopedic Foot and Ankle Score (AOFAS) questionnaire was administered preoperatively and postoperatively. Results: The mean follow-up time was 2.6 (range 2–3.5) years. There were no wound complications and no Achilles tendon ruptures. At 1 year postoperatively, the internal brace group was superior to the suture bridge group in terms of the VAS scores (p = 0.003). However, no differences were noticed between the two groups in either the VAS or the AOFAS scores at 2 years postoperatively. Conclusions: The medial approach in combination with the suture bridge technique was effective in treating calcific Achilles tendinopathy. The knotless internal brace technique involved less pain compared to the knot-tying suture bridge technique only at the early postoperative stage.

Double Row Fixation is More Costly and Does Not Have Clinical Benefit Over Single Anchor for Insertional Achilles Tendon Surgery

Surgical repair of insertional Achilles tendinosis is indicated in the face of failed conservative measures. Several methods for this repair have been described, and the optimal method is not universally agreed upon. In addition, the cost of medical care is important, and should be considered when determining the surgical repair for each patient. The purpose of this study is to compare implant costs between a single anchor or 4 anchor, double row repair, and evaluate associated outcomes. A retrospective comparative trial was performed for this purpose. The entire study encompassed 110 patients, 78 with a single anchor repair, and 32 with a double row repair. The average implant cost of the single anchor repair was $391.18 ± $272.10 and the double row repair was $1811.2 9 ± $169.47, p < .001. The groups did not have a statistically significant difference in complications (9% with single anchor vs 6.3% with double row, p = 1.0) or revisions 6.4% with single anchor vs 3.1% with double row, p = .67). The only difference in demographics between the groups was that the single anchor group had a higher percentage of female patients (p = .04). While the double row repair has been shown to have favorable biomechanical results, the present study did not show a benefit in complications or revisions and was a more costly repair technique. Surgeons should take these findings in consideration when choosing the repair technique when surgery is indicated.

Review of Achilles Tendon Reattachment Using Double-Row Knotted and Knotless Techniques in the Management of Insertional Achilles Tendinopathy

Insertional Achilles tendinopathy represents a chronic degenerative condition affecting the insertion of the Achilles. Surgery is indicated in recalcitrant cases and often involves extensive debridement followed by subsequent repair of the insertion. In the present study, we evaluate the results of knotted and knotless double-row suture systems for Achilles reattachment. Despite the popularity of double-row repairs, there is a relative paucity of clinic data regarding efficacy of the available implants. In a retrospective cohort study, 38 patients (40 Achilles tendons) who received double-row repairs between November 2012 and December 2016 were evaluated. In addition to demographic information, preoperative pain scores and symptom duration were recorded. Perioperative and postoperative records were reviewed, and telephone interviews were conducted to assess patient satisfaction, functional status, postoperative pain, and information regarding surgical complications. At a mean follow-up of 32.5 months, 35 (92.1%) patients reported satisfaction with the outcome. Decreased pain levels were reported in 38 (95%) ankles, with 21 (52.5%) ankles being rated pain-free postoperatively. Of the patients working prior to surgery, 20 (95.2%) were able to return to normal work duties, and all 11 (100%) patients who engaged in sports preoperatively were able to return to the same level of activity. Two patients developed postoperative infections, one of which required operative debridement. No Achilles avulsions were encountered. No significant differences were noted between the 2 operative techniques. Considering the available biomechanical data, along with high patient satisfaction rates and low rate of complications, double-row repair offers a viable option for recalcitrant insertional Achilles tendinopathy.

Chronic insertional Achilles tendinopathy secondary to congenital os Achilles: A case report

INTRODUCTION

Insertional Achilles tendinopathy is a common overuse disorder affecting the foot and ankle that can lead to the development of a Haglund's deformity with chronicity, a retrocalcaneal exostosis that forms at the Achilles insertion site, further increasing pain and dysfunction.

PRESENTATION OF CASE

We report a case of a healthy, 35-40-year-old male with chronic left-sided insertional Achilles pain beginning in early adolescence. Physical exam demonstrated bilateral prominences on the posterior aspect of both heels, exquisitely tender on the left and without range of motion deficits. Imaging demonstrated a large calcific ossicle clearly within the tendinous insertion of the Achilles onto the left calcaneus. He underwent surgical intervention to provide pain relief and restore function. He exhibited full recovery post-operatively and has now returned to full functional activities.

DISCUSSION

Given his symptom pathogenesis and progression, this patient may likely have suffered from chronic insertional Achilles tendinopathy due to an accessory ossicle that we believe was congenital. Current literature describes an additional secondary ossification center that appears over the dorsal, posterosuperior surface of the calcaneus. We suspect that there was a lapse in fusion at this additional ossification center that contributed to his pathological condition.

CONCLUSION

This case report presents a unique occurrence of Achilles tendinopathy likely due to an accessory ossicle of congenital etiology. This highlights the importance of investigating the prevalence of this condition in those with chronic insertional Achilles tendinopathy, thus providing meaningful insight in considering effective treatment modalities in the management of these patients.

Clinical outcomes following surgical management of insertional Achilles tendinopathy using a double-row suture bridge technique with mean two-year follow-up

BACKGROUND

The clinical outcomes following surgical management of insertional Achilles tendinopathy (IAT) vary depending on the surgical technique used to reattach the Achilles tendon following debridement. The aim of this study was to investigate the clinical outcomes of patients with IAT who underwent surgical management with a double-row suture bridge technique used to reattach the Achilles tendon.

METHODS

A retrospective review of consecutive patients diagnosed with IAT, who underwent surgical management utilising a double-row suture bridge technique (Arthex Speedbridge), and a minimum of 3-month follow-up were included. The primary outcome was the Manchester-Oxford Foot Questionnaire (MOXFQ) Index score which is a patient reported outcome measure (PROM). Secondary outcomes included EuroQol EQ-5D-5L health-related quality of life PROM and complication rates.

RESULTS

Between July 2013 and June 2020, 50 consecutive patients (23 male; 27 female) were included. The mean age (± standard deviation) was 52.3 ± 11.3 (range 29.0-84.3). Pre- and post-operative PROM data were available for all cases. The mean follow-up was 2.4 ± 1.9 years. The MOXFQ Index score improved from 48.5 to 12.4 (p < 0.01), EQ-5D-5L improved from 2.7 ± 0.46 to 1.2 ± 0.37 (p < 0.01), and EQ-VAS improved from 48.0 ± 18.4 to 84.1 ± 12.6 (p < 0.01). Four patients had complications which were of minimal clinical relevance and caused no deviation from routine recovery. There were no cases of tendon rupture.

CONCLUSION

This study has demonstrated that surgical management of IAT is safe and effective with clinical improvement in both clinical and general health-related quality of life outcome PROMs.

[Application of percutaneous transcalcaneal reconstruction technique for acute Achilles tendon insertion avulsion]

OBJECTIVE

To introduce a percutaneous transcalcaneal reconstruction technique for the treatment of acute Achilles tendon insertion avulsion, and to assess its short-term effectiveness.

METHODS

Between January 2014 and June 2020, 25 patients with acute Achilles tendon insertion avulsion were treated with the percutaneous transcalcaneal reconstruction technique. There were 24 males and 1 female, with an average age of 44.1 years (range, 34-60 years). The disease duration was 1-5 days (mean, 1.8 days). There were 23 cases of sports injury and 2 cases of fall injury. The preoperative American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score was 55.6±6.7 and the visual analogue scale (VAS) score was 4.6±0.5. The operation time, intraoperative blood loss, hospital stay, related complications, the time of weight-bearing standing with a slightly raised heel, and the time of walking with a slightly raised heel were recorded. The AOFAS ankle-hindfoot score and the VAS score were used to evaluate the ankle joint function and the pain. Achilles tendon continuity was examined by color Doppler ultrasonography and healing of the Achilles tendon was examined by MRI. At last follow-up, the Arner-Lindholm scale was used to evaluate the effectiveness.

RESULTS

The operation time was 45-50 minutes (mean, 46.8 minutes). The intraoperative blood loss was 10-20 mL (mean, 13.8 mL). The hospital stay was 4-6 days (mean, 4.9 days). The color Doppler ultrasonography before discharge showed the continuous recovery of the Achilles tendon. All incisions healed by first intention, and there was no complication such as sural nerve injury or deep venous thrombosis of lower extremity. All patients were followed up 15-50 months (mean, 30.3 months). After 14-21 days, the patients started to weight-bearing stand with a slightly raised heel, with an average of 17.6 days; they began to walk with a slightly raised heel at 20-28 days, with an average of 23.7 days. MRI showed that the Achilles tendon healed at last follow-up. The AOFAS score was 90.0±3.2 at 6 months after operation and 95.8±4.5 at last follow-up, and the VAS scores were 1.7±0.6 at 6 months and 1.0±0.8 at last follow-up, which were all improved when compared with those before operation (P<0.05); the difference was also significant between the two time points after operation (P<0.05). According to the Arner-Lindholm scale, the effectiveness at last follow-up was excellent in 25 cases. All patients had returned to sports.

CONCLUSION

The percutaneous transcalcaneal reconstruction technique is a promising alternative option in treating acute Achilles tendon insertion avulsion, for it can achieve early rehabilitation and better ankle function recovery.

Surgical Takedown Approaches to Insertional Achilles Tendinopathy: A Systematic Review

Various techniques of surgical detachment for treatment of insertional Achilles tendinopathy have been described, including lateral release, medial release, central tendon splitting (CTS), and complete detachment. A systematic review of electronic databases was performed, encompassing 17 studies involving 703 patients and 746 feet, to compare outcomes associated with surgical takedown techniques. Observed results include wound complication rates (CTS 2.8%; Lateral 0%; Medial 0.4%; Complete 1.3%), postoperative rupture rates (CTS 0.7%; Lateral 0.8%; Medial 0.7%; Complete 2.6%), rate of revision (CTS 0.4%; Lateral 0.9%; Medial 4.2%; Complete 2.6%), rate of infection (CTS 1.1%; Lateral 1.7%; Medial 3.7%; Complete 6.5%). Lateral takedown group was found to have a statistically significant lower rate of complications compared to the complete takedown group (p = .0029). In light of these results, it is recommended that patient characteristics such as case specific tendon pathology and calcaneal morphology take precedent in determining the surgical approach to Achilles takedown.

Insertional Achilles Tendinopathy: Analysis of 166 Procedures and Return to Activity

The surgical procedure for Insertional Achilles tendinopathy (IAT) varies widely with no consensus as to approach and documenting return to activity (RTA). This study presents outcomes of surgery for IAT by a single surgeon, documenting activity level and return to activity. From January 2001 through January 2018, 166 procedures were reviewed. Surgery included debridement of the Achilles insertion, resection of the superior calcaneus and bursa, and re-attachment with suture anchors. There were 110 males and 56 females. The majority of patients in the entire cohort were runners (n = 54). The average age of the cohort was 50.3 ± 12.1 years (range 20-80). Average follow-up was 114.0 ± 63.5 months (range 6-222 months). Average RTA for males and females were 6.43 months and 7.22 months, (p = .2), respectively. There was no difference in RTA between patients who had calcific tendinosis (n = 84) and noncalcific tendinosis (n = 82). Complications were 2 infections, 2 DVTs, and 17 deep suture reactions with a total complication rate of 12.6%; there were no re-ruptures postoperatively. There was no significant difference in number of complications between absorbable and nonabsorbable suture in the anchors (p = .41). The average RM score was 1.5 ± 0.7. The RM scores were better for males (p = .002), but there were no differences in RTA or complications between sexes. Overall, 95.8% of the procedures resulted in improved outcome and ability to return to activity including sports. This retrospective investigation shows surgical intervention for IAT yields good results with an average return to activity including sports in approximately 7 months.

Endoscopic speed bridge: A new treatment for insertional Achilles tendinopathy

Surgical treatment may be indicated after failure of medical management of insertional Achilles tendinopathy, and may consist in simple calcaneoplasty, increasingly performed endoscopically, or in open detachment-reattachment. Isolated calcaneoplasty sometimes shows poor results in case of multiple overlooked lesions (bone, tendon, pre- or retro-tendinous bursitis). Detachment-reattachment may be indicated in case of tendon lesion, but incurred scar and infection related risk in up to 30% of cases in certain reports. In this context, we describe a new original technique using an endoscopic Achilles speed bridge, which we call the "snake technique" for the S-shaped order of performance of the 6 necessary approaches.

Endoscopic treatment of insertional Achilles tendinopathy: A cadaver feasibility study

INTRODUCTION

One treatment option in insertional Achilles tendinopathy is open reconstruction of the insertion, resecting the enthesophyte and posterosuperior calcaneal prominence and reinserting the tendon using anchors. Although classically performed as an open procedure, the necessary subcutaneous release and dissection can entail problems of healing in at-risk patients.

HYPOTHESIS

It is possible to perform Achilles disinsertion-reinsertion with posterosuperior calcaneal prominence resection endoscopically, without iatrogenic risk, enabling complete resection of the enthesophyte and posterosuperior calcaneal prominence and satisfactory reinsertion.

MATERIAL AND METHODS

An operative technique was developed, consisting in Achilles disinsertion-reinsertion with resection of the posterosuperior calcaneal prominence and enthesophyte endoscopically via 5 portals. A feasibility study was conducted in an anatomy laboratory on 10 foot specimens, assessing iatrogenic impact. Bone resection quality was assessed under endoscopic and fluoroscopic control. Reinsertion quality was assessed endoscopically and on dissection of the specimens.

RESULTS

In the 10 procedures, there were no failures. Resection of the calcifications and the calcaneal prominence was complete in all cases. Reinsertion was satisfactory in all cases. There were no iatrogenic neural lesions.

DISCUSSION/CONCLUSION

It was possible to perform endoscopic Achilles disinsertion-reinsertion with resection of the posterosuperior calcaneal prominence and enthesophyte. The procedure did not seem to increase iatrogenic risk, and enabled complete bone resection and satisfactory reinsertion. This endoscopic technique now needs to be validated clinically, with comparison versus open surgery.

Conventional vs Accelerated Rehabilitation Protocol Following Reattachment of Achilles Tendon for Insertional Achilles Tendinopathy

BACKGROUND

No studies have compared early vs conventional postoperative weightbearing following suture bridge Achilles tendon reattachment. We, therefore, evaluated postoperative functional outcomes in these patients.

METHODS

We collected data on 49 patients who underwent surgical treatment of insertional Achilles tendinopathy using a central Achilles tendon-splitting approach and reattachment with suture bridge technique by a single surgeon. Functional outcomes were measured by a visual analog scale (VAS) for pain, Foot and Ankle Ability Measure (FAAM), and Short Form Health Survey (SF-36) at 3, 6, and 12 months postoperatively. The differences in outcomes were analyzed using multiple linear regression.

RESULTS

Eighteen and 31 patients underwent the conventional and accelerated protocols, respectively; their corresponding mean ages were similar, 53 and 57 years, as were all other baseline characteristics. The mean scores (conventional vs accelerated group) for VAS for pain, FAAM, and SF-36 in the conventional group at 3 months postoperatively were 4 ± 1 vs 3 ± 1 points, 53 ± 8 vs 68 ± 3 points, and 57 ± 15 vs 67 ± 10 points (P < .05 for each comparison). There were no statistically significant differences between the groups at 6 and 12 months postoperatively. All patients could perform the single heel raise test at 6 months, and none experienced complications.

CONCLUSION

In this small study, short-term functional outcomes were better in the accelerated group. More data are needed before the accelerated program can be recommended.

Endoscopic resection of enthesopathy via a direct midline transtendinous approach with associated reattachment of the Achilles tendon (endo-REDMTART): a cadaveric feasibility study

PURPOSE

The aim of our study was to determine the feasibility of an all-posterior endoscopic resection of enthesopathy via direct midline transtendinous approach with detachment and reattachment of the Achilles tendon (endo-REDMTART).

MATERIALS & METHODS

Endo-REDMTART was performed in 10 ankles by two foot and ankle surgeons. Posterolateral and posteromedial portals were utilized. Three accessory, more distal portals were utilized (one posterolateral, one posteromedial, and one midline transtendinous). We measured the quality of the resection of the calcaneal spur and the length of tendon that was able to be reattached to the calcaneus.

RESULTS

The procedure was successful in all 10 cases. The mean minimum thickness of resected calcaneal spur was 7 mm (5-9 mm) thick, and the mean anteroposterior distance was 23 mm (20-25 mm). In all 10 cases, the maximum distance between the distal Achilles tendon and calcaneus was 1 mm (0-1 mm), with good tendon-bone contact.

CONCLUSIONS

The data here suggest that endo-REDMTART is feasible. This procedure provides all of the advantages of endoscopic technique without compromising the efficacy of Haglund deformity resection.

Endoscopic SpeedBridge Procedure for the Treatment for Insertional Achilles Tendinopathy: The Snake Technique

Surgical treatment of insertional Achilles tendinopathy is indicated in case of failure of conservative therapy. A choice is then made within a large spectrum of procedures from minimally invasive techniques such as endoscopic calcaneoplasty to more invasive procedures, such as dorsal closing wedge calcaneal osteotomy. Isolated calcaneoplasties can lead to poor results in cases of pre-existing Achilles tendon lesions; in these cases the tendon disinsertion is justified. In this context, we describe an endoscopic treatment of insertional Achilles tendinopathy.

Functional Outcomes of Insertional Achilles Tendinopathy Treatment: A Systematic Review

BACKGROUND

Achilles tendinopathy is a common clinical problem that can be either insertional or noninsertional, and effective treatment of each type can vary. We sought to investigate the current evidence on different treatment methods for insertional Achilles tendinopathy with a focus on functional outcomes.

METHODS

We performed a systematic review of the available literature using the PubMed/MEDLINE and Cochrane Central Register of Controlled Trials databases. Data from included studies were categorized according to treatment method and reported with respect to functional outcomes and complications.

RESULTS

A total of 1,457 abstracts were reviewed; 54 studies with 2,177 patients met the inclusion criteria. Among the 54 studies, 6 operative techniques and 6 nonoperative treatments were evaluated.

CONCLUSIONS

Eccentric exercises and low-energy extracorporeal shockwave therapy (ESWT) have the greatest evidence for the initial management of insertional Achilles tendinopathy. ESWT has been increasingly studied in recent years, but more high-quality evidence is needed. Operative treatment with tenotomy, debridement, retrocalcaneal bursectomy, and calcaneal exostectomy is effective. Flexor hallucis longus tendon transfer may benefit cases of more severe disease.

Heel Complications

Postoperative complications can be burdensome on both the patient and the surgeon. Attention in literature is often directed toward different forms of treatment and successful outcomes in surgery. The incentive of this article is to bring insight toward postoperative complications in rearfoot surgery, more specifically, the repair of the Achilles tendon with suture tape and suture anchors. This article directs attention to the recent reports on hypersensitivity reactions seen with the use of suture tape and nonabsorbable suture anchors and may encourage physicians to make patients aware of this potential complication when using these materials.

Biomechanical Comparison of All-Soft Suture Anchor Single-Row vs Double-Row Bridging Construct for Insertional Achilles Tendinopathy

BACKGROUND

Two common operative fixation techniques for insertional Achilles tendinopathy are the use of all-soft suture anchors vs synthetic anchors with a suture bridge. Despite increasing emphasis on early postoperative mobilization, the biomechanical profile of these repairs is not currently known. We hypothesized that the biomechanical profiles of single-row all-soft suture anchor repairs would differ when compared to double-row suture bridge repairs.

METHODS

Achilles tendons were detached from their calcaneal insertions on 6 matched-pair, fresh-frozen cadaver through-knee amputation specimens. Group 1 underwent a single-row repair with all-soft suture anchors. Group 2 was repaired with a double-row bridging suture bridge construct. Achilles-calcaneal displacement was tracked while specimens were cyclically loaded from 10 to 100 N for 2000 cycles and then loaded to failure. Linear mixed models were used to analyze the independent effects of age, body mass index, tendon morphology, repair construct, and footprint size on clinical and ultimate failure loads, Achilles-calcaneal displacement, and mode of failure.

RESULTS

The suture bridge group was independently associated with an approximately 50-N increase in the load to clinical failure (defined as more than 5 mm tendon displacement). There was no difference in ultimate load to failure or tendon/anchor displacement between the 2 groups.

CONCLUSION

This cadaveric study found that a double-row synthetic bridge construct had less displacement during cyclic loading but was not able to carry more load before clinical failure when compared to a single-row suture anchor construct for the operative repair of insertional Achilles tendinopathy.

CLINICAL RELEVANCE

Our data suggest that double-row suture bridge constructs increase the load to clinical failure for operative repairs of insertional Achilles tendinopathy. It must be noted that these loads are well below what occurs during gait and the repair must be protected postoperatively without early mobilization. This study also identified several clinical factors that may help predict repair strength and inform further research.

Study of the clinical and functional results of open calcaneoplasty and tendinous repair for the treatment of the insertional tendinopathy of the Achilles' tendon

BACKGROUND AND OBJECTIVES

Insertional tendinopathy accounts for 23% of the pathology of the Achilles tendon. Surgery is indicated when conservative treatment of pain and functional limitation fails. Our objective is to analyse the clinical-functional results of surgical treatment with disinsertion, debridement and double row reattachment with high strength suture tape.

MATERIAL AND METHODS

We present 13 patients with insertional Achilles tendinopathy, treated between February 2015 and October 2016. In all of them we performed inverted T-tendon disinsertion, debridement and calcareoplasty followed by double row tendon re-anchorage, without knots, with high resistance suture tape. Functional results were assessed with the AOFAS scale before and after surgery, with an average follow-up of 22 months.

RESULTS

The patients, 11 males and 2 females, with an average age of 43 years, presented a preoperative AOFAS score of 34.77±10.1 that reached 90.85±7 points after the operation, with an average increase of 56.08 points (IC 95% 48.13-64.02; P<0.01). The time to return to sports activities was 19 weeks (16-22). There were no complications.

CONCLUSION

The technique we present reports excellent results as a surgical treatment of insertional Achilles tendinopathy with intralesional calcification; it allows a wide contact surface between bone and tendon and an earlier return to previous sports activity.

Medial Epicondyle Fractures: Biomechanical Evaluation and Clinical Comparison of 3 Fixation Methods Used in Pediatric Patients

BACKGROUND

Screw fixation is the most commonly employed fixation strategy for displaced medial epicondyle fractures, but in younger patients with minimal ossification, the fracture fragment may not accommodate a screw. In these situations, Kirschner-wires (K-wire) or suture anchors may be utilized as alternatives. The purposes of this study were to examine the biomechanical properties of medial epicondyle fractures fixed with a screw, K-wires, or suture anchors, to evaluate clinical outcomes and complications of patients 10 years of age or younger treated with these approaches, and to perform a cost-analysis.

METHODS

Biomechanical assessment: Immature pig forelimbs underwent an osteotomy through the medial epicondyle apophysis, simulating a fracture. These were then fixed with a screw, K-wires or suture anchors. Cyclic elongation (mm), displacement (mm), load to failure (N), and stiffness (N/mm) were assessed. Clinical assessment: a retrospective review was performed of patients 10 years of age or younger with a medial epicondyle fracture fixed with these strategies. Radiographic outcomes, postoperative data and complications were compared. These data were used to perform a cost-analysis of each treatment approach.

RESULTS

Biomechanically, screws were stronger (P=0.047) and stiffer (P=0.01) than the other constructs. Clinically, 51 patients met inclusion criteria (screw=27, wires=11, anchor=13). Patients treated with K-wires were younger (P<0.05) and patients treated with screw fixation had a shorter casting duration (P=0.008). Irrespective of treatment strategy, all fractures healed (100%) and only 1 patient in the screw group lost reduction. Clinical outcomes and complications were similar between groups, but the suture anchor group was less likely to require a second surgery for implant removal (P<0.05). This lower reoperation rate led to a cost-saving of 10%.

CONCLUSIONS

Biomechanically, all 3 approaches provided initial fixation exceeding the forces observed across the elbow joint with routine motion. The screw construct was the strongest and stiffest. Clinically, all 3 strategies were acceptable, with screw fixation offering a shorter casting duration, but greater implant removal need with higher associated costs.

Outcomes of Operative Management of Insertional Achilles Tendinopathy in the Young vs Elderly

Background:

Insertional Achilles tendinopathy (IAT) is a common cause of chronic posterior heel pain. Surgical intervention reproducibly improves patients’ pain and functional status. We hypothesized that patients older than 60 years would have similar improvements in pain and function and low rates of complications after surgery for IAT when compared to a younger cohort.

Methods:

Retrospective review of adult case series in patients undergoing surgical management of IAT. Patients were stratified into those 60 years and younger and those older than 60 years. Patients with prior or concomitant surgical procedures and revisions were excluded. Visual analog scale (VAS), Short Form–36 Physical Component Summary and Mental Component Summary (SF-36 PCS/MCS) scores, wound infection, and recurrence, defined as a redevelopment of heel pain in the operative extremity within 6 months, were assessed with a minimum follow-up of 12 months. Statistical analysis was performed using linear regression mixed models and χ2 analysis. Thirty-seven patients were enrolled, with 38 operative heels. The younger cohort had an average age of 49.1 (range, 26-60) years. The older group had an average age of 66.8 (range, 61-76) years.

Results:

VAS and SF-36 PCS scores for the entire cohort significantly improved at 6 and 12 months postoperatively ( P < .001). Postoperative SF-36 MCS scores for the cohort significantly improved only at 12 months ( P < .001). No significant differences between the young and elderly were seen with regard to improvements in VAS and SF-36 PCS/MCS at 6 or 12 months postoperatively. Multiple linear regression models showed no significant difference between age groups and VAS score, SF-36 PCS/MCS, or change in pain scores after controlling for comorbidities. No significant difference in overall complication rates was seen between the 2 groups (4.9% vs 29.4%, P = .104). There was 1 recurrence of heel pain in the younger group and 4 recurrences of pain in the older group (23.5%) at 6 months, of which 2 resolved at 1 year. There was 1 case of a superficial wound infection requiring antibiotics in the older cohort (5.9%). No patients required surgical revision.

Conclusion:

Surgical management of IAT in an older population produced similar improvements in clinical results when compared to a younger cohort, with no significant increase in postoperative complications.

Surgical treatment of insertional Achilles tendinopathy: results after removal of the subcutaneous bursa alone-a case series

Background

Insertional Achilles tendinopathy is well known to be difficult to treat, especially when there is intra-tendinous bone pathology. This study is a case series on patients with chronic insertional Achilles tendon pain and major intra-tendinous bony pathology together with bursa and tendon pathology, treated with excision of the subcutaneous bursa alone.

Methods

Eleven patients (eight men and three women) with a mean age of 44 years (range 24–62) and a chronic (>6 months) painful condition from altogether 15 Achilles tendon insertions were included. In all patients, ultrasound examination showed intra-tendinous bone pathology together with pathology in the tendon and subcutaneous bursa, and all were surgically treated with an open excision of the whole subcutaneous bursa alone. This was followed by full weight-bearing walking in a shoe with open heel for 6 weeks.

Results

At follow-up 21 (median, range 12–108) months after surgery, 9/11 patients (12/15 tendons) were satisfied with the result of the operation and 10/11 (13/15 tendons) were back in their previous sport and recreational activities. The median VISA-A score had improved from 41 (range 0–52) to 91 (range 33–100) (p<0.01).

Conclusion

In patients with chronic painful insertional Achilles tendinopathy with intra-tendinous bone pathology, tendon and bursa pathology, open removal of the subcutaneous bursa alone can relieve the pain and allow for Achilles tendon loading activities. The results in this case series highlight the need for more studies on the pain mechanisms in insertional Achilles tendinopathy and the need for randomised studies to strengthen the conclusions.

Optimal Outcomes for Acute Avulsion Fracture of the Achilles Tendon Treated With the Insertional Reattachment Technique: A Case Series of 31 Cases With Over 2 Years of Follow-up

BACKGROUND

Avulsion fracture of the Achilles tendon is a less common but debilitating disorder. There is a paucity of literature on this problem.

PURPOSE

To present a retrospective case series assessing the clinical outcomes of avulsion fracture of the Achilles tendon after a reattachment procedure and to identify potential factors predicting postoperative outcomes.

STUDY DESIGN

Case series; Level of evidence, 4.

METHODS

A consecutive case series of 35 patients with acute insertional rupture of the Achilles tendon who received a reattachment procedure between 2011 and 2017 were reviewed. All patients were measured and classified by magnetic resonance imaging (MRI) and surgical findings. Patient-reported outcomes were evaluated using the visual analog scale (VAS) for pain, American Orthopaedic Foot & Ankle Society (AOFAS) Ankle-Hindfoot Scale, Foot Function Index (FFI), Tegner score, and Ankle Activity Score (AAS). The range of motion and single-legged heel raise test were also conducted for both ankles.

RESULTS

Thirty-one out of 35 (88.57%) patients were followed up for an average of 43.65 months. The VAS pain score and AOFAS Ankle-Hindfoot score improved from 4.87 ± 1.61 preoperatively to 2.07 ± 1.57 postoperatively and from 58.32 ± 18.66 preoperatively to 87.32 ± 7.53 postoperatively, respectively (both P < .001). The mean FFI, AAS, and Tegner scores after the operation were 11.84 ± 1.62, 5.71 ± 2.18, and 4.61 ± 1.31, respectively. Compared with the intact ankle, the mean deficit in dorsiflexion in the involved ankle was 9.54°± 6.25° (range, 0.59°-23.70°; P < .001) and the mean deficit in plantarflexion in the involved ankle was 6.31°± 4.02° (range, 0.24°-14.92°; P < .001). Thirty patients could perform the single-legged heel raise on the operative leg. A larger body mass index was associated with worse postoperative AOFAS and FFI outcomes. Longer follow-up predicted statistically significantly better FFI scores. Better postoperative dorsiflexion was associated with better postoperative FFI, AAS, and Tegner scores, and a statistically significant interaction was found between the VAS score and plantarflexion deficit. Age, preoperative insertional tenderness, Haglund deformity, and MRI classification showed little association with postoperative outcomes.

CONCLUSION

This study demonstrated that the reattachment procedure for acute avulsion fracture of the Achilles tendon can achieve firm fixation and promising outcomes.

Surgical Strategies for the Treatment of Insertional Achilles Tendinopathy

Insertional Achilles tendinopathy is one of the most common Achilles tendon disorders and often results in substantial heel pain and functional disability. There is consensus that treatment of insertional Achilles tendinopathy should start with nonoperative modalities. Surgery should be reserved for patients who fail exhaustive conservative treatment for a period of 3 months to 6 months and include débridement of insertional calcifications. Intratendinous degenerative tissue should be débrided and any Haglund deformity resected. Different surgical techniques have been described for reattachment of the distal Achilles tendon. The authors' preferred surgical technique includes the knotless double-row footprint reconstruction. Postoperative complications are not rare.

Suture Augmented Versus Standard Anterior Cruciate Ligament Reconstruction: A Matched Comparative Analysis

PURPOSE

To compare outcomes between standard anterior cruciate ligament reconstruction (ACLR) using hamstring grafts with and without suture augmentation (SA).

METHODS

Patients who underwent ACLR with hamstring autografts or allografts with minimum 2-year follow-up were retrospectively reviewed. Patients undergoing ACLR with SA were matched 1:1 by age, gender, body mass index, graft type, and revision status to standard ACLR. Range of motion, pain, postoperative activity, patient-reported outcome measures (PROMs), and complications were collected. Paired 2-tailed Student's t-tests and Pearson's χ²-tests were used for continuous and categorical variables, respectively. A multivariate analysis of variance was conducted. Return to preinjury activity level was assessed using Spearman's rho and Pearson's χ²-tests.

RESULTS

Sixty patients at a mean age of 29.50 ± 6.60 years, 43.4% male, body mass index 26.27 ± 3.37, and follow-up of 29.54 ± 5.37 months were included. Preoperative PROMs were not significantly different (P >. 05). Postoperative range of motion was similar between groups (P = .457). Postoperative average daily (0.60 ± 1.25 vs 1.66 ± 1.90) and maximum daily pain (1.57 ± 1.83 vs 3.35 ± 2.28) were significantly lower for SA (P < .014). SA predicted improvement in PROMs (P < .05) and maximum pain scores (P = .001). SA was significantly correlated with improved time to return to preinjury activity level (9.17 ± 2.06 vs 12.88 ± 3.94 months; P = .002) and percentage of preinjury activity level (93.33% ± 13.22% vs 83.17% ± 17.69%; P = .010). There was a trend toward improved rate of return to preinjury activity level for SA (76.7% vs 56.7%; P = .100).

CONCLUSIONS

Our study demonstrates that SA hamstring ACLRs were associated with improved PROMs, less pain, and a higher percentage of and earlier return to preinjury activity level when compared with standard hamstring ACLRs without evidence of overconstraint.

Lateral versus central tendon-splitting approach to insertional Achilles tendinopathy: a retrospective study

INTRODUCTION

This study aimed to compare operative outcomes between the lateral approach (LA) and the central approach (CA) to insertional Achilles tendinopathy (IAT).

METHODS

We retrospectively reviewed patients who underwent surgical treatment for IAT using the LA or CA. Patients' demographic data, postoperative complications and satisfaction rate were reviewed. Clinical outcomes were prospectively assessed preoperatively, at three months postoperatively and at the last visit, including patients' visual analogue scale (VAS) scores for pain, American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Scale scores and 36-item Short Form Health Survey (SF-36) scores.

RESULTS

There were 39 patients in the LA group and 32 in the CA group. In each group, average VAS and AOFAS Scale scores improved significantly. SF-36 scores improved in most parameters. No significant difference in baseline score; average AOFAS Scale score at each visit; and mean VAS score preoperatively and at last visit; satisfaction rate; and overall complication rate were observed between the groups. The mean VAS score in the LA group at postoperative three months was significantly lower than that in the CA group (2.7 ± 2.5 vs. 4.4 ± 3.0; p = 0.016). There were significantly more cases of delayed wound healing in the LA group than in the CA group (2.6% vs. 15.6%; p = 0.049).

CONCLUSION

Both approaches had comparable outcomes for IAT in terms of functional improvement, pain relief, overall enhancement of patients' health condition and overall postoperative complication rate. The LA provided better short-term pain relief and reduced delayed wound healing compared with the CA.

Proximal to Distal Exostectomy for the Treatment of Insertional Achilles Tendinopathy

When insertional Achilles tendinopathy is addressed surgically via a central-Achilles splitting approach, the calcaneal osteotomy has classically been performed from distal to proximal. We describe a simple proximal to distal technique that allows optimal resection of both the calcaneal exostosis and Achilles enthesophyte, minimizes risk to the soft tissues and skin, provides a bony attachment surface parallel to the axis of the Achilles tendon, and avoids the risk of osteotomy extension into the subtalar joint.

Surgical Correction of Haglund's Triad Using a Central Tendon-Splitting Approach: A Retrospective Outcomes Study

We evaluated the surgical outcomes of Haglund's triad using a central tendon-splitting approach, with Achilles tendon partial detachment and debridement, excision of the retrocalcaneal bursa, resection of Haglund's prominence, and reattachment of the Achilles tendon. The medical records of 22 patients (22 heels) who had undergone surgical correction of Haglund's triad from January 2010 to December 2015 were reviewed retrospectively. The visual analog scale pain score, American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot scale score, and 36-item Short-Form Health Survey physical and mental component scores were prospectively collected preoperatively, 6 months postoperatively, and at the last visit. The scores of a subjective question involving satisfaction were prospectively collected at the last visit. Possible risk factors were also evaluated. We reviewed the data from 12 females and 10 males, with the mean age of 59.2 ± 7.3 years and a mean follow-up duration of 15.1 ± 4.6 months. Significant improvement was found in the mean visual analog scale pain score, average American Orthopaedic Foot and Ankle Society Ankle-Hindfoot scale score, and 36-item Short-Form Health Survey physical component scale score. The overall satisfaction rate was 77.3% (17 of 22). Postoperative complications included 2 cases of delayed wound healing and 1 case of sensation loss over the heel wound. No Achilles tendon rupture or wound infection developed. Gender and body mass index did not affect the surgical outcomes. The surgical technique we used for Haglund's triad provided effective pain relief, function improvement, and overall enhancement of patients' health condition. More research is required to further evaluate the outcomes of our surgical approach to treat Haglund's triad and the possible risk factors.

Liquifying PLDLLA Anchor Fixation in Achilles Reconstruction for Insertional Tendinopathy

Insertional Achilles tendinopathy (IAT) is a frequent cause of posterior heel pain and is often associated with Haglund's deformity. Surgical correction for refractory cases of IAT has been well studied; however, the method of tendon fixation to bone in these procedures remains controversial, and to date, no standard technique has been identified for tendon fixation in these surgeries. Often, after Haglund's resection, there is large exposed cancellous surface for Achilles reattachment, which may require unique fixation to optimize outcomes. Previous studies have consistently demonstrated improved patient outcomes after Achilles tendon reconstruction with early rehabilitation with protected weight bearing, evidencing the need for a strong and stable anchoring of the Achilles tendon that allows early weight bearing without tendon morbidity. In this report, we highlight the design, biomechanics, and surgical technique of Achilles tendon reconstruction with Haglund's deformity using a novel technique that utilizes ultrasonic energy to liquefy the suture anchor, allowing it to incorporate into surrounding bone. Biomechanical studies have demonstrated superior strength of the suture anchor utilizing this novel technique as compared with prior techniques. However, future research is needed to ensure that outcomes of this technique are favorable when compared with outcomes using traditional suture anchoring methods.

Reattachment using the suture bridge augmentation for Achilles tendon avulsion fracture with osteoporotic bony fragment

Although avulsion fractures of the calcaneal tuberosity are rare injuries, these can be a challenging problem with frequent complications, such as loss of reduction and soft tissue problem. Anatomical reduction and internal fixation are indicated to avoid these pitfalls and to restore function of the triceps surae. However, the best fixation device and operative technique are still controversial. A case that achieved satisfactory clinical outcome through a reattachment technique using the suture bridge augmentation for Achilles tendon avulsion fracture with osteoporotic bony fragment is presented.

Efficacy of Achilles Suture Bridge Technique for Insertional Achilles Tendinosis in an Obese and Athletic Patient

Here, we report the efficacy of the suture bridge technique for treating insertional Achilles tendinosis in an obese and athletic patient. A 48-year-old man presented to our department with a 6-month history of left posterior heel pain. The patient was an athlete (triathlon) and appeared obese (height: 197 cm, body weight: 120 kg, body mass index: 30.9). A diagnosis of insertional Achilles tendinosis was made. Because 6 months of conservative treatments had failed, we performed open resection of the calcaneal exostosis and Haglund's deformity along with debridement of the degenerative tissue of the tendon. Wide detachment of the insertion of the Achilles tendon was necessary, and reattachment of the tendon was performed using the Arthrex SpeedBridge(TM) system (Arthrex, Inc., Naples, FL). Six weeks postoperatively, this patient was allowed to walk with full weight bearing. Twelve weeks after surgery, this patient started jogging with neither pain nor evidence of Achilles tendon rupture. The suture bridge technique was effective for the reconstruction of the Achilles tendon in an obese and athletic patient. J. Med. Invest. 63: 310-314, August, 2016.

Return to Sport and Physical Activity After Calcaneoplasty for Insertional Achilles Tendinosis

The primary aim of the present study was to examine the time required and the ability of a consecutive series of patients undergoing open calcaneoplasty with reattachment of the Achilles tendon to return to their preoperative level of sporting activity. The secondary aim was to evaluate the functional outcomes and complication profile of this procedure. Open calcaneoplasty was performed on 22 feet (14 left [63.6%] and 8 right [36.4%]) in 22 consecutive patients, with a mean age of 55.28 ± 9.17 years. The mean postoperative follow-up time was 21.5 ± 8.2 months. The time required to return to work and sports and the functional outcomes were recorded. Of the 22 patients, 70% were able to return to their preoperative level of sporting activity after open calcaneoplasty with Achilles tendon reattachment at a mean of 5.14 ± 3.76 (range 2 to 12) months postoperatively. All the patients were able to resume their preoperative employment status at a mean of 3.30 ± 1.73 (range 0.5 to 6) months. Statistically significant improvements were found in the short-form 36-item questionnaire, American Orthopedic Foot and Ankle Society hindfoot scale, and visual analog scale for pain scores postoperatively. Most patients (72.8%) subjectively scored excellent or very good outcomes on a Likert scale for patient satisfaction. Most patients were able to return to their preoperative level of sporting activity after open calcaneoplasty with Achilles tendon reattachment, and they were all able to resume their preoperative employment status. In the present series of patients, the procedure resulted in satisfactory outcomes with statistically significant improvements in patient-reported functional scores and pain relief after surgery.

A Proposed Staging Classification for Minimally Invasive Management of Haglund's Syndrome with Percutaneous and Endoscopic Surgery

Haglund's syndrome encompasses several different pathologies, including Haglund's deformity, insertional Achilles tendonopathy, retrocalcaneal bursitis, and superficial bursitis. Traditionally treated with open surgery, there is increasing interest in a more minimally invasive approach to this difficult region to reduce complications and improve the rate and ease of recovery. We review the evidence available for 2 of these techniques: the endoscopic calcaneoplasty and percutaneous Zadek's calcaneal osteotomy (also known as Keck and Kelly's osteotomy). The senior author's classification for management of the condition is presented as well as describing his operative technique for these procedures.

Knotless Repair of Achilles Tendon Rupture in an Elite Athlete: Return to Competition in 18 Weeks

Rupture of the Achilles tendon is an increasingly common injury, particularly in physically active males, and current evidence favors minimally invasive surgical repair. We describe the case of a 36-year-old male elite bobsled athlete with complete rupture of the Achilles tendon. He was treated with surgical repair of the ruptured tendon using an innovative, minimally invasive procedure based on an internal bracing concept and was able to undergo early mobilization and aggressive physiotherapy rehabilitation. His recovery was such that he returned to training at 13 weeks postoperatively and participated in an international competition at 18 weeks, winning a World Cup silver medal. He subsequently raced at the 2014 Winter Olympic Games at 29 weeks after surgery. At >2 years since his injury, he has experienced no complications or reinjury. This represents an exceptional recovery that far exceeds the standard expected for such injuries. The use of this technique for athletes could enable accelerated return to sporting activity and attainment of their preinjury activity levels.

Percutaneous Reconstruction of the Anterolateral Ligament of the Knee With a Polyester Tape

Recent advances in surgeons' understanding of the anatomic, biomechanical, and radiologic features of the anterolateral ligament (ALL) of the knee have led to an increased interest in reconstruction of this structure as part of the management of knee instability. Even without any technical flaws and proper positioning of the bone tunnels, there is a small subset of patients, approximately 7% of all patients, who experience some residual anterolateral rotational instability after anterior cruciate ligament reconstruction. For this reason, some researchers have turned again toward the anterolateral aspect of the knee and specifically the ALL. In this technical note, the surgical steps for percutaneous reconstruction of ALL of the knee using a polyester tape are described.

Use of a Central Splitting Approach and Near Complete Detachment for Insertional Calcific Achilles Tendinopathy Repaired With an Achilles Bridging Suture

After 3 to 6 months of conservative management for insertional calcific Achilles tendinopathy, operative intervention might be warranted. Despite a success rate of 75% to 100% with surgery, no consensus has been reached on the amount of acceptable detachment of the Achilles tendon. The present case series reports on the results of a central splitting approach with 80% to 90% detachment of the Achilles insertion repaired with a double-row bridging suture device. A total of 14 patients (16 heels) for whom nonoperative management for insertional calcific Achilles tendinopathy had previously failed were enrolled in the present study they had undergone surgical management. The patients were followed up for a mean of 18 (range 11 to 25) months postoperatively and were evaluated using the American Orthopaedic Foot and Ankle Society Hind Foot scoring system, 36-item Short Form Health Survey questionnaire, and pre- and postoperative visual analog pain scale. The mean visual analog pain scale core had decreased 5.84 (range 1 to 9) points postoperatively (p < .001). The mean postoperative American Orthopaedic Foot and Ankle Society Hind Foot score was 87 ± 19.7 (range 52 to 105) points. One patient reported moderate pain with no limitation of activities. The mean 36-item Short-Form Health Survey score for physical functioning was 77.7 (range 30 to 100) points postoperatively in 11 patients. No patient reported incisional discomfort. All 14 patients (16 heels) reported being satisfied and had returned to their previous functional status. Thus, the central splitting Achilles approach with anchoring of the Achilles insertion using the double-row suture device is a safe and reasonable option in the operative treatment of insertional calcific Achilles tendinopathy.

Knotted versus knotless suture bridge repair of the achilles tendon insertion: a biomechanical study

BACKGROUND

Surgical treatment of insertional Achilles tendinopathy often involves detachment and debridement of the Achilles tendon insertion. A recent study has shown that knotted suture bridge fixation of the Achilles to the calcaneus is biomechanically superior to single-row fixation, but there is an absence of literature on the use of different suture bridge constructs to repair the Achilles tendon.

HYPOTHESIS

There will be no significant difference in the load to failure, mode of failure, tendon strain, tendon stiffness, repair site gapping, or footprint size when comparing knotted suture bridge repair to knotless suture bridge repair of the Achilles tendon after detachment for insertional Achilles tendinopathy.

STUDY DESIGN

Controlled laboratory study.

METHODS

A single specimen from each pair of 10 cadaveric Achilles tendons was randomized to 1 of 2 Achilles insertion repair groups: knotted (n = 10) or knotless (n = 10) suture bridge repair. Repaired footprint size was measured, and then cyclic testing from 10 to 100 N for 2000 cycles was performed. This was followed by measurement of tendon strain, repair site displacement, load to failure, and tendon stiffness.

RESULTS

The knotted suture bridge repair had a significantly higher load to failure compared with the knotless suture bridge (mean ± SD, 317.8 ± 93.6 N vs 196.1 ± 12.1 N, respectively; P = .001). All constructs failed at the tendon-suture interface. Tendon strain after cyclic testing was significantly greater in the knotless (1.20 ± 1.05) compared with the knotted (0.39 ± 0.4) suture repair groups (P = .011). There was no significant difference in footprint size between the knotted (230.3 ± 63.3 mm(2)) and knotless (248.5 ± 48.8 mm(2)) groups (P = .40). There was also no significant difference in stiffness (knotted = 76.4 ± 8.0 N/mm; knotless = 69.6 ± 10.9 N/mm; P = .17) and repair site displacement after cyclic testing (knotted = 2.8 ± 1.2 mm; knotless = 3.6 ± 1.1 mm; P = .17).

CONCLUSION

During suture bridge repair of the Achilles tendon after detachment, knots at the proximal suture anchors significantly improve the biomechanical strength of the repair.

CLINICAL RELEVANCE

This study demonstrated that the knotless suture bridge repair had a significantly lower load to failure than the knotted suture bridge. Surgeons should be aware of these biomechanical differences, as they influence the postoperative rehabilitation protocol and may lead to higher surgical complication rates.

Outcome of calcaneoplasty in insertional achilles tendinopathy

ABSTRACT

BACKGROUND

Insertional Achilles tendinopathy may be associated with Haglund's deformity and result in chronic pain. It is usually refractory to conservative management. The aim of this study was to assess the outcome of calcaneoplasty performed in our hospital.

METHODS

Eight patients were prospectively evaluated pre- and postoperatively using the American Orthopaedic Foot and Ankle Society (AOFAS) Hindfoot Score, Visual Analogue Scale (VAS) and Short Form (SF) 36, as well as satisfaction rate. Average follow-up duration was 12.4 months.

RESULTS

The mean pre and post-operative AOFAS scores were significantly improved at three and six months. SF 36 improved in most parameters. The postoperative VAS score improved significantly and was 0 at 2 years. The procedure was rated as good to excellent by seven of the subjects.

CONCLUSION

We recommend calcaneoplasty for the treatment of insertional Achilles tendinopathy.

Knee medial collateral ligament and posteromedial corner anatomic repair with internal bracing

An internal brace is a ligament repair bridging concept using braided ultrahigh-molecular-weight polyethylene/polyester suture tape and knotless bone anchors to reinforce ligament strength as a secondary stabilizer after repair and return to sports, which may help resist injury recurrence. An internal brace may provide augmentation during knee medial and posteromedial corner anatomic repair. In patients with combined, chronic, symptomatic anterior cruciate ligament (ACL)-posteromedial corner laxity, combined ACL reconstruction with posteromedial corner reconstruction is indicated. Our ACL technique was previously published with video illustration in Arthroscopy and Arthroscopy Techniques. The purpose of this article is to describe, with video illustration, knee posteromedial corner reconstruction using anatomic repair with internal brace augmentation.
