RESUMO

Background: Primary repair of the anterior cruciate ligament (ACL) confers an alternative to ACL reconstruction in appropriately selected patients. Purpose: To prospectively assess survivorship and to define the clinically meaningful outcomes after ACL repair. Study Design: Case series; Level of evidence, 4. Methods: Included were consecutive patients with Sherman grade 1-2 tears who underwent primary ACL repair with or without suture augmentation between 2017 and 2019. Patient-reported outcomes (Lysholm, Tegner, International Knee Documentation Committee, Western Ontario and McMaster Universities Osteoarthritis Index, and Knee injury and Osteoarthritis Outcome Score [KOOS] subscales) were collected preoperatively and at 6 months, 1 year, and 2 years postoperatively. The minimal clinically important difference (MCID) was calculated using a distribution-based method, whereas the Patient Acceptable Symptom State (PASS) and substantial clinical benefit (SCB) were calculated using an anchor-based method. Plain radiographs and magnetic resonance imaging (MRI) were obtained at 6 months, 1 year, and 2 years postoperatively. Results: A total of 120 patients were included. The overall failure rate was 11.3% at 2 years postoperatively. Changes in outcome scores required to achieve the MCID ranged between 5.1 and 14.3 at 6 months, 4.6 and 8.4 at 1 year, and 4.7 and 11.9 at 2 years postoperatively. Thresholds for PASS achievement ranged between 62.5 and 89 at 6 months, 75 and 89 at 1 year, and 78.6 and 93.2 at 2 years postoperatively. Threshold scores (absolute/change based) for achieving the SCB ranged between 82.8 and 96.4/17.7 and 40.1 at 6 months, between 94.7 and 100/23 and 45 at 1 year, and between 95.3 and 100/29.4 and 45 at 2 years. More patients achieved the MCID and PASS at 1 year compared with 6 months and 2 years. For SCB, this trend was also observed for non-KOOS outcomes, while for KOOS subdomains, more patients achieved the SCB at 2 years. High-intensity signal of the ACL repair (odds ratio [OR], 31.7 [95% CI, 1.5-73.4]; P = .030) and bone contusions on MRI (OR, 4.2 [95% CI, 1.7-25.2]; P = .041) at 1 year postoperatively were independently associated with increased risk of ACL repair failure. Conclusion: The rate of clinically meaningful outcome improvement was high early after ACL repair, with the greatest proportion of patients achieving the MCID, PASS, and SCB at 1 year postoperatively. Bone contusions involving the posterolateral tibia and lateral femoral condyle as well as high repair signal intensity at 1 year postoperatively were independent predictors of failure at 2 years postoperatively.

RESUMO

Anterior cruciate ligament (ACL) tears are routinely treated with an ACL reconstruction. This is based on historical literature reporting high failure rates after ACL repairs in addition to the limited healing potential of the ACL. Recently, improved understanding of pathophysiology of ligamentous healing has led to increasing interest in treating proximal avulsions with excellent tissue quality in the acute setting, as this technique allows for ACL healing. Potential advantages of ACL repair include preservation of native proprioceptive and kinematics of the knee, avoidance of graft harvesting morbidity and the possibility to perform a primary ACL reconstruction in case of failure. As a consequence, several techniques for ACL repair have been proposed that can be performed in isolation or with suture augmentation. The primary aim of this technical note is to describe step-by-step the ACL repair technique with and without suture augmentation. The secondary aim of the current study is to review the indications, patient selection and advantages of the technique.

RESUMO

Acute Achilles tendon rupture can be treated either surgically or nonsurgically. The flexor hallucis longus (FHL) has been used successfully in patients with large chronic Achilles tendon defects. The aim of this study was to describe the clinical outcomes of isolated endoscopic FHL transfer in patients with acute Achilles tendon ruptures at a minimum follow-up of 18 months. Fifty-six male patients with an average age of 36.3 years who underwent endoscopic FHL transfer as a treatment for acute Achilles tendon ruptures were included. Follow-up was for a mean (± standard deviation) of 27.5 ± 7.29 months. At 18 months postoperatively, the Achilles tendon total rupture score mean was 95 ± 4.26, and the American Orthopaedic Foot and Ankle Society score was a mean of 96.4 ± 4.31. The median value for FHL tendon dynamometry on the surgical side was 95.72 (range 70.1 to 142), and 100.7 (range 68 to 161) for the nonoperated side. Mean ankle plantarflexion strength at 18 months was 19.19 ± 2.55 kg • m compared with the uninjured side of 19.27 ± 2.16 kg • m. Relative Achilles tendon resting angle showed a mean of -0.25° ± 2.43°. Magnetic resonance imaging performed at a minimum of 18 months postoperatively showed a homogeneous continuous Achilles tendon signal for 43 patients and heterogeneous signal intensity in 13 patients (23.21%). No patients reported any great toe complaints or symptomatic deficits of flexion strength. No neurovascular or skin complications were encountered. The current study demonstrated satisfactory and comparable results with minimal complications when using the endoscopic FHL tendon transfer in surgical management of acute Achilles tendon ruptures, compared with the currently used methods.

RESUMO

OBJECTIVES: Injury to the lateral ligament complex of the ankle is one of the most common sports-related injury. Usually lateral ankle evolves with excellent clinical recovery with non surgical treatment, however, near about 30% develop a lateral chronic instability sequela. Several open and arthroscopic surgical techniques have been described to treat this medical condition. MATERIAL AND METHODS: Of the 22 patients who were treated; 18 males and 4 females, and aged from 17-42 years (mean 28 years). All patients presented a history of more than three ankle sprains in the last two years and presented positive anterior drawer and talar tilt test of the ankle in the physical examination. We perform an anterior arthroscopy of the ankle in order to treat asociated disease and then we performed "All inside¨ lateral ligament repair through two portals (anteromedial and anterolateral) using an anchor knotless suture. RESULTS: Clinical outcome evaluations were performed at a mean follow up of 25 months. (R: 17-31). Overall results has been shown by means of the American Orthopaedic Foot and Ankle Society (AOFAS). Mean AOFAS scores improved from 63 points (range 52-77) preoperatively to 90 points (range 73-100) at final follow up. No recurrences of ankle instability were found in the cases presented. CONCLUSION: Several surgical procedures have been described during the last years in order to treat chronic ankle instability. ¨All inside¨ lateral ligament reconstruction presents lower local morbidity than open procedures with few complications. Moreover, it is a reproductible technique, with high clinical success rate, few complications and relatively quick return to sports activities. A high knowledge of the anatomic landmarks should be essential to avoid unwated injuries.

RESUMO

Ankle ligament injuries are one of the most frequent lesions identified in professional soccer players. In most cases, the ligaments involved are the anterior talofibular ligament and the calcaneal fibular ligament. In the present report, we describe a professional soccer player who sustained an ankle sprain that did not respond to initial therapy. The findings from radiographic and magnetic resonance images were inconclusive. Ultimately, rupture of the posterior, transverse ligament with avulsion of the tibial labrum was identified as the cause of his ongoing ankle pain. Confirmation of the pathologic findings and successful treatment were performed arthroscopically.

RESUMO

Endoscopy for the posterior region of the ankle through two portals is becoming more widespread for the treatment of a large number of conditions which used to be treated with open surgery years ago. The tendon of the flexor hallucis longus (FHL) travels along an osteofibrous tunnel between the posterolateral and posteromedial tubercles of the talus. Chronic inflammation of this tendon may lead to painful stenosing tenosynovitis. The aim of this report is to describe two cases depicting an accessory tendon which is an anatomical variation of the flexor hallucis longus in patients with posterior friction syndrome due to posterior ankle impingement and associated with a posteromedial osteochondral lesion of the talus. The anatomical variation (FDAL) described was a finding during an endoscopy of the posterior region of the ankle, and we have spared it by sectioning the superior flexor retinaculum only. The accessory flexor digitorum longus is an anatomical variation and should be taken into account when performing an arthroscopy of the posterior region of the ankle. We recommend this treatment on this type of injury although we admit this does not make a definite conclusion.
