Arthroscopic Assisted Anterior Cruciate Ligament Tibial Spine Avulsion Reduction and Cortical Button Fixation

Double Decker anterior cruciate ligament avulsion

Distal anterior cruciate ligament avulsion from tibial side is an unusual injury. It can be either bony avulsion, which is more common, or rarely a soft tissue peeling of tibial spine with no bone injury. This case report represents a very infrequent injury of combined soft tissue peeling of distal anterior cruciate ligament along with bony avulsion of tibial spine in a 12-years-old boy after falling from his bike.

Arthroscopic fixation techniques for tibial eminence fractures in pediatric patients: a review

The introduction of new internal fixation devices and arthroscopic techniques has led to significant changes in the surgical treatment of tibial eminence fractures (TEFs) in children. In recent years, arthroscopic surgery has arisen as the gold standard for the treatment of TEFs. This popularity of arthroscopic techniques has reduced surgical complications and improved patient prognosis. In this paper, we investigate the current situation of the use of arthroscopic fixation techniques for pediatric TEFs. We searched the PubMed database using the terms "arthroscopic treatment and tibial eminence," "arthroscopic treatment and tibial spine," "tibial eminence avulsion", "tibial spine fracture", with no limit on the year of publication. From these articles, we reviewed the use of various arthroscopic TEFs fixation techniques reported in the current literature. Overall, we found that the choice of fixation method seems to have no effect on clinical outcomes or imaging results. However, if an easy, strong fixation that is less prone to epiphyseal damage is desired, as a junior practitioner, the anchor technique should be mastered first, whereas for senior practitioners, a variety of fixation techniques for TEFs should be mastered, including anchors, sutures, and screws, so that personalized fixation can be achieved with the least amount of trauma, operative time, and complications. Higher quality studies are needed in the future to provide Useful evidence to determine the optimal fixation technique in terms of clinical outcomes, function, and complications.

Arthroscopic ACL Avulsion Fixation With Adjustable Loop Length Cortical Endobutton

Various surgical management techniques have been introduced to treat anterior cruciate ligament avulsion fractures. There is disagreement among orthopedic surgeons about which fixation device to use during arthroscopy. Recently, there has been an increase in the use of arthroscopic techniques for fixation, and different devices such as sutures, screws, and fiber wires are being considered. The development of fiber wires has made it possible to use them in comminuted avulsions with satisfactory stability, whereas screws cannot be used in such cases. Sutures do not provide adequate stability for early range of motion compared to other methods. The article then goes on to describe a specific arthroscopic fixation technique that uses an adjustable loop cortical button to manage the avulsed fragment and provide stability.

Tibial Spine Avulsion Repair With FiberRing Suture and Anterior Cruciate Ligament Repair TightRope

Tibial spine avulsion fractures occur predominantly in children and young adults and are an uncommon type of knee injury. To ensure knee stability and preserve range of motion with minimal knee laxity, it is essential to restore anterior cruciate ligament length through surgical reduction and fixation of the fracture. Achieving anatomic reduction of tibial spine avulsion fractures with an arthroscopic approach is a technically complex procedure. In this Technical Note and accompanying video, we describe a unique fixation repair of tibial spine avulsion fractures using Arthrex FiberRing sutures and an Arthrex ACL Repair TightRope. The technique presented is an effective method to reduce tibial spine avulsion fractures to anatomic position with a variable tensioning system that allows for a strong and secure fixation method.

[Treatment of tibial insertion avulsion fracture of anterior cruciate ligament involving anterior root of lateral meniscus with multi-point fixation with anchor and suture]

Objective

To investigate the effectiveness of arthroscopic multi-point fixation with anchor and suture in the treatment of tibial insertion avulsion fracture of anterior cruciate ligament (ACL) involving the anterior root of lateral meniscus (LM).

Methods

A retrospective analysis was conducted on the clinical data of 28 patients with tibial insertion avulsion fracture of ACL involving the anterior root of LM who were treated with arthroscopic multi-point fixation with anchor and suture between October 2017 and January 2023. There were 12 males and 16 females with the mean age of 26 years (range, 13-57 years). There were 20 cases of sports injury and 8 cases of traffic accident injury. In 2 cases of old fracture, the time from injury to operation was 45 days and 90 days, respectively; in 26 cases of fresh fracture, the time from injury to operation was 3-20 days (mean, 6.7 days). According to the Meyers-McKeever classification, there were 4 cases of type Ⅱ, 11 cases of type Ⅲ, and 13 cases of type Ⅳ. The preoperative Lysholm knee function score was 42.1±9.0, the International Knee Documentation Committee (IKDC) score was 40.0±7.3, and the Tegner score was 0.7±0.7.

Results

All operations were successfully completed, and the incisions healed by first intention. All the 28 patients were followed up 5-60 months (mean, 20.4 months). During the follow-up, there was nocomplication such as infection, vascular or nerve injury, loosening or breakage of internal fixator, or stiffness of knee joint. Postoperative X-ray films showed satisfactory fracture reduction and firm fixation. All fractures healed clinically, and the healing time was 8-16 weeks (mean, 10.3 weeks). At last follow-up, Lachman test and anterior drawer test were negative. At last follow-up, Lysholm knee function score was 92.4±5.5, IKDC score was 91.6±4.4, and Tegner score was 5.2±1.1, which significantly improved when compared with preoperative scores ( t=-22.899, P<0.001; t=-29.870, P<0.001; t=-19.979, P<0.001).

Conclusion

Multi-point fixation with anchor and suture in the treatment of tibial insertion avulsion fracture of ACL involving the anterior root of LM can not only fix the LM, but also effectively reduce and fix the avulsion fracture, which can obtain good effectiveness.
