Triceps Tendon

Background: Triceps tendon ruptures typically result from a forceful elbow eccentric contraction. The goal of a distal triceps tendon repair is to reattach the torn tendon back to the olecranon. Surgery is indicated for patients with complete rupture of the triceps tendon or symptomatic partial tears with failed conservative management. The complication rate occurs in 22% of patients postoperatively; however, only 0% to 4% of patients suffer a re-rupture of the tendon. Indications: We present a case of a highly active 38-year-old right-hand dominant man with acute onset of left posterior elbow pain following 1-handed pushup resulting in a complete distal triceps avulsion with 1.5 cm retraction. Technique: The distal triceps avulsion was repaired in a double row fashion using 2 double-loaded all-suture anchors in the medial row and anchor in the lateral row through a posterior approach. Results: Full anatomic footprint coverage was able to be achieved intraoperatively, and gentle range of motion from 0 to 90 degrees of flexion did not result in gap formation. Discussion/Conclusion: Successful outcomes with full anatomic footprint coverage of the distal triceps tendon can be achieved through a double row repair configuration.

Double Row Repair

Background: Triceps tendon ruptures are rare orthopaedic injuries that almost always require surgical repair. This study tests the biomechanical properties of an original anchorless double-row triceps repair against a previously reported knotless double-row repair. Hypothesis: The anchorless double-row triceps repair technique will yield similar biomechanical properties when compared with the knotless double-row repair technique. Study Design: Controlled laboratory study. Methods: Eighteen cadaver arms were randomized into 2 groups. One group received the anchorless repair and the other received the knotless anchor repair. A materials testing system (MTS) machine was used to cycle the repaired arms from 0° to 90° with a 2.5-pound weight for 1500 cycles at 0.25 Hz. Real-time displacement of the tendon was measured during cycling using a probe. Load to failure was performed after completion of cyclic loading. Results: The mean displacement with the anchorless technique was 0.77 mm (SD, 0.25 mm) at 0° (full elbow extension) and 0.76 mm (SD, 0.38 mm) at 90° (elbow flexion). The mean displacement with the anchored technique was 0.83 mm (SD, 0.57 mm) at 0° and 1.01 mm (SD, 0.62 mm) at 90°. There was no statistically significant difference for tendon displacement at 0º ( P = .75) or 90º ( P = .31). The mean load to failure with the anchorless technique was 618.9 N (SD, 185.6 N), while it was 560.5 N (SD, 154.1 N) with the anchored technique, again with no statistically significant difference ( P = .28). Conclusion: Our anchorless double-row triceps repair technique yields comparable biomechanical properties to previously described double-row triceps tendon repair techniques, with the added benefit of avoiding the cost of suture anchors. Clinical Relevance: This anchorless double-row triceps tendon repair can be considered as an acceptable alternative to a knotless anchor repair for triceps tendon ruptures.

Triceps tendon ruptures and avulsions are rare injuries and are often associated with systemic diseases. This paper illustrates the unique case of a 20-year-old female patient with pseudohypoparathyroidism, who sustained bilateral triceps avulsion fractures after a fall. She underwent suture anchor fixation, augmented with tension band suture as double row repair with excellent post-operative results. We describe the pathophysiology of this injury and the unique method of fixation, which can be an alternative effective method to repair these injuries.

Triceps Tendon

Triceps tendon ruptures are rare injuries and are frequently missed on initial presentation to the emergency department. In cases of complete rupture, surgical repair is recommended but no guidelines exist on the optimum reconstructive technique or rehabilitation. We present a surgical technique and rehabilitation programme for the management of these injuries. A midline posterior incision is performed, the ruptured triceps tendon is identified and mobilized, and the tendon footprint is prepared. The tendon is then repaired using bone suture anchors, with a parachute technique, and held in 40° of flexion. The rehabilitation programme is divided into five phases, over a period of 12 weeks. Range of movement is gradually increased in a brace for the first 6 weeks. Rehabilitation is gradually increase in intensity, progressing from isometric extension exercises to weight-resisted exercises, and finally plyometrics and throwing exercises. Our surgical technique provides a solid tendon repair without the need for further metalwork removal. The graduated rehabilitation programme also helps to protect the integrity of the repair at the same time as enabling patients to gradually increase the strength of the triceps tendon and ultimately return to sport activities.

Background: Restoring footprint anatomy, minimizing gap formation, and maximizing the strength of distal triceps tendon repairs are essential factors for a successful healing process and return to sport. Hypothesis: The novel V-shaped distal triceps tendon repair technique with unicortical button fixation closely restores footprint anatomy, provides minimal gap formation and high ultimate failure load, and minimizes iatrogenic fracture risk in acute/subacute distal triceps tendon tears. Study Design: Controlled laboratory study. Methods: Twenty-four cadaveric elbows (mean ± SD age, 66 ± 5 years) were randomly assigned to 1 of 3 repair groups: the transosseous cruciate repair technique (gold standard), the knotless suture-bridge repair technique, and the V-shaped distal triceps tendon repair technique. Anatomic measurements of the central triceps tendon footprint were obtained in all specimens with a 3-dimensional digitizer before and after the repair. Cyclic loading was performed for a total of 1500 cycles at a rate of 0.25 Hz, pulling in the direction of the triceps. Displacements were measured on the medial and lateral tendon sites with 2 differential variable reluctance transducers. Load to failure and construct failure mode were recorded. Results: The mean triceps bony insertion area was 399.05 ± 81.23 mm2. The transosseous cruciate repair technique restored 36.6% ± 16.8% of the native tendon insertion area, which was significantly different when compared with the knotless suture-bridge repair technique (85.2% ± 14.8%, P = .001) and the V-shaped distal triceps tendon repair technique (88.9% ± 14.8%, P = .002). Mean displacement showed no significant difference between the V-shaped distal triceps tendon repair technique (medial side, 0.75 ± 0.56 mm; lateral side, 0.99 ± 0.59 mm) and the knotless suture-bridge repair technique (1.61 ± 0.97 mm and 1.29 ± 0.8 mm) but significance between the V-shaped distal triceps tendon repair technique and the transosseous cruciate repair technique (4.91 ± 1.12 mm and 5.78 ± 0.9 mm, P < .001). Mean peak failure load of the V-shaped distal triceps tendon repair technique (732.1 ± 156.0 N) was significantly higher than that of the knotless suture-bridge repair technique (505.4 ± 173.9 N, P = .011) and the transosseous cruciate repair technique (281.1 ± 74.8 N, P < .001). Mechanism of failure differed among the 3 repairs, with the only olecranon fracture occurring in the knotless suture-bridge repair technique at the level of the lateral row suture anchors. Conclusion: At time zero, the V-shaped distal triceps tendon repair technique and the knotless suture-bridge repair technique both provided anatomic footprint coverage. Ultimate load to failure was highest for the V-shaped distal triceps tendon repair technique, while gap formation was different only in comparison with the transosseous cruciate repair technique. Clinical Relevance: The V-shaped distal triceps tendon repair technique provides an alternative procedure to other established repairs for acute/subacute distal triceps tendon ruptures. The reduced repair site motion of the V-shaped distal triceps tendon repair technique and the knotless suture-bridge repair technique at the time of surgery may allow a more aggressive rehabilitation program in the early postoperative period.

Introduction. Obesity is an increasingly common comorbidity that may negatively affect outcomes following orthopaedic surgery. It is valuable to determine whether obese patients are vulnerable for postoperative complications. The purpose of this study was to analyze data from the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) to determine the effect of obesity on surgical treatment of Achilles tendon ruptures. Methods. Patients who underwent a surgical repair of the Achilles tendon were retrospectively identified through the ACS NSQIP. The patients were divided into 2 cohorts (obese and nonobese), then perioperative and postoperative factors were evaluated for association with obesity. Results. A total of 2128 patients were identified, of whom 887 (41.7%) were classified as obese. Obesity correlated with an increased operative time, 60.9 versus 56.1 minutes. The only postoperative complication associated with obesity was wound dehiscence. Logistic regression adjusted for comorbid conditions demonstrated that obesity was not associated with an increased risk of wound dehiscence. Conclusion. A large segment of the patient population undergoing Achilles tendon repair is obese. Obesity was found to have an increased association with wound dehiscence, likely related to comorbid conditions, following Achilles tendon repair. Obesity was not significantly associated with any other complication. Levels of Evidence: III, Retrospective Cohort Study

BACKGROUND: Missed traumatic Achilles tendon ruptures in children are rarely reported in the literature. Various techniques have been described to reconstruct delayed Achilles tendon ruptures for adults, but the long-term consequences in the growing child are unknown. CLINICAL CASE: The article presents a clinical observation of a 8-year-old girl with missed rupture of the Achilles tendon operated 7 weeks after the trauma by end-to-end Kessler-type sutures augmented with the plantaris tendon. At 2-year follow-up, the patient was completely asymptomatic. DISCUSSION: A review of the literature shows that this is the third neglected pediatric case of post-traumatic Achilles tendon rupture. The first case concerns a 10-year-old boy treated successfully six weeks after the traumat by open surgical repair using the Bunnell sutures technique. The second patient was a 7-year-old girl, she was operated 8 weeks after the trauma with a termino-terminal tenorrhaphy using the Bunnell technique augmented with the plantaris tendon. CONCLUSIONS: Using the plantaris tendon to reinforce the Achilles tendon repair offers satisfactory results with minimal morbidity. Prognosis depends on the extent of tendon defect which determines the long-term functional outcome. Any skin wound that sits on the back of the leg requires a systematic and careful physical examination to check the integrity of the Achilles tendon.

Abstract Background: Tendon injury is a common but tough medical problem. Unsatisfactory clinical results have been reported in tendon repair using mesenchymal stem cells (MSCs) therapy, creating a need for a better strategy to induce MSCs to tenogenic differentiation. This study was designed to investigate the role of hypoxia in the tenogenic differentiation of MSCs in vitro and in vivo and to compare the tenogenic differentiation capacities of different MSCs under hypoxia condition in vitro. Methods: Adipose tissue-derived MSCs (AMSCs) and bone marrow-derived MSCs (BMSCs) were isolated and characterized by the expression of MSC-specific markers and tri-lineage differentiation. The expression of hypoxia induced factor-1 alpha (Hif-1α) and the proliferation of AMSCs and BMSCs were examined in order to confirm the establishment of hypoxia condition. qRT-PCR, western blot, and immunofluorescence staining were used to evaluate the expression of tendon-associated marker Col-1a1, Col-3a1, Dcn, and Tnmd in AMSCs and BMSCs under hypoxia and/or Tgf-β1 condition. In vivo, a patellar tendon injury model was established. Normoxic and hypoxic BMSCs were cultured and implanted. Histological, biomechanical and transmission electron microscopy analyses were performed to assess the improved healing effect of hypoxic BMSCs on tendon injury. Results: Hypoxia remarkably increased the expression of Hif-1α and the proliferation of AMSCs and BMSCs. Our in vitro results detected that hypoxia not only promoted a significant increase in tenogenic markers in both AMSCs and BMSCs compared with the normoxia group, but also showed higher inductility compared with Tgf-β1. In addition, hypoxic BMSCs exhibited higher potential of tenogenic differentiation than hypoxic AMSCs. Our in vivo results demonstrated that hypoxic BMSCs possessed better histological and biomechanical properties than those of normoxic BMSCs, as evidenced by histological scores, quantitative analysis of immunohistochemical staining for Col-1a1 and Tnmd, the range and average of collagen fibril diameters and patellar tendon biomechanical tests. Conclusions: These findings suggested that hypoxia may be a practical and reliable strategy to induce tenogenic differentiation of BMSCs for tendon repair and could enhance the effectiveness of MSCs therapy in treating tendon injury.

Category: Sports; Other Introduction/Purpose: Achilles tendon ruptures are a common sporting injury, mostly occurring in men over the age of 40. Operative repair of Achilles tendon can lead to earlier return to activity and improved function in the active population. Mini-open repairs have recently been described for effective treatment of Achilles tendon ruptures. We aim to describe our unique mini- open Achilles tendon repair technique and to report our clinical outcomes. Methods: We retrospectively reviewed charts of patients from January 2010 and July 2019 who underwent a 3cm mini-open Achilles tendon repairs, without additional targeting devices, for closed acute Achilles tendon ruptures. Patients were followed up for a minimum of one year. We recorded pre- and postoperative Foot and Ankle Disability Index (FADI), visual analog scale (VAS), and the Foot and Ankle Outcome Score (FAOS) scores. Subgroup analysis were performed for acute repairs (< 2 weeks) and subacute (2-6 weeks). Two-sided student’s t-test to compare preoperative and postoperative outcomes for continuous variables. Chi-square analyses were used to determine the strength of correlation between categorical variables. A p-value of < .05 was considered significant for all statistical analyses. Results: A total of 33 patients met the inclusion criteria and are included in this study. The mean age of our cohort was 43.8 years old (range 22-78) and 78.8% of patients were male. The mean length of follow-up was 4.4 years (range 1.0-9.8 years). The mean time from injury to surgery was 15.6 days (1-45 days). Patients reported a mean return to their previous level of activity at a mean of 5.6 months (range 1.7-22.1). The mean pre- and postoperative outcomes scores improved significantly for both the acute and subacute repair groups (p < 0.05). There were no significant differences for postoperative outcomes scores between the acute and subacute Achilles repair groups (p > 0.05). There were no reported complications in our patient cohort. Conclusion: Patients showed improvements in postoperative patient-reported outcome scores with minimal complications. There were no significant difference in outcomes for acute versus subacute repairs. Our mini-open Achilles tendon repair, which required no additional targeting instrumentation, has shown favorable mid-term results.
