Lateral Ankle Ligament Reconstruction

Background: Anatomic lateral ankle ligament reconstruction has been proposed for patients with chronic ankle instability. A reliable approach is a reconstruction technique using an allograft and 2 fibular tunnels. A recently introduced approach that entails 1–fibular tunnel reconstruction might reduce the risk of intraoperative complications and ultimately improve patient outcome. Hypothesis: We hypothesized that both reconstruction techniques show similar ankle stability (joint laxity and stiffness) and are similar to the intact joint condition. Study Design: Controlled laboratory study. Methods: A total of 10 Thiel-conserved cadaveric ankles were divided into 2 groups and tested in 3 stages—intact, transected, and reconstructed lateral ankle ligaments—using either the 1– or the 2–fibular tunnel technique. To quantify stability in each stage, anterior drawer and talar tilt tests were performed in 0°, 10°, and 20° of plantarflexion (anterior drawer test) or dorsiflexion (talar tilt test). Bone displacements were measured using motion capture, from which laxity and stiffness were calculated together with applied forces. Finally, reconstructed ligaments were tested to failure in neutral position with a maximal applicable torque in inversion. A mixed linear model was used to describe and compare the outcomes. Results: When ankle stability of intact and reconstructed ligaments was compared, no significant difference was found between reconstruction techniques for any flexion angle. Also, no significant difference was found when the maximal applicable torque of the 1-tunnel technique (9.1 ± 4.4 N·m) was compared with the 2-tunnel technique (8.9 ± 4.8 N·m). Conclusion: Lateral ankle ligament reconstruction with an allograft using 1 fibular tunnel demonstrated similar biomechanical stability to the 2-tunnel approach. Clinical Relevance: Demonstrating similar stability in a cadaveric study and given the potential to reduce intraoperative complications, the 1–fibular tunnel approach should be considered a viable option for the surgical therapy of chronic ankle instability. Clinical randomized prospective trials are needed to determine the clinical outcome of the 1-tunnel approach.

Category: Ankle; Sports Introduction/Purpose: Ankle sprains are one of the most common athletic injuries. If a patient fails to improve through conservative management, surgery is an option to restore ankle stability. The purpose of this study is to analyze the variability across rehabilitation for patients undergoing lateral ankle ligament repair, reconstruction, or suture tape augmentation. Methods: 26 protocols were found. Inclusion criteria was protocols for ankle ligament surgery. Protocols for nonoperative care were excluded. A rubric was created to analyze weightbearing, range of motion (ROM), immobilization, single leg exercises, return to running, and return to sport (RTS). Results: There was variability especially in recommendations for immobilizing brace, partial and full weigh bearing, specific ROM movements of the ankle, and return to single leg exercise and running. For repair and reconstruction, none of these categories had greater than 60% agreement. 100% (12/12) of repair and 86% (12/14) of reconstruction protocols recommended no ROM postoperatively, and 86% (6/7) repair and 78% (11/14) reconstruction recommended no weightbearing postoperatively, making postoperative ROM and weightbearing status the most consistent aspects across protocols. Suture tape augmentation protocols generally allowed rehabilitation on a quicker timeline with full weightbearing by week 4-6 in 100% (3/3) of protocols and full ROM by week 8-10 in 66% (2/3). RTS was consistent in repair protocols (100% at week 12-16). Conclusion: ROM was variable across protocols and did not always match up with supporting literature. Return to sport was likely to correlate between protocols and the literature. Weightbearing was consistent between protocols. The variability between programs demonstrated the need for standardization of rehabilitation.

Ankle Ligament Injury

Background. Lateral ankle ligament injuries are most common in sports, which affects athletes in all ages. It has been found that lateral ankle ligaments are injured in 1 of 10000 physically active people. Higher sports level professional players and amateurs need to return to sport early with no physical, psychological and economic consequences. Studies search for the most effective treatment after lateral ankle ligament injuries. Research aim – to perform a systematic review and determine the effect of early physiotherapy on pain and function after lateral ankle ligament injury. Methods. We conducted literature search using the Pubmed, Ebsco, Pedro, Google scholar databases, and chose controlled trials where early physiotherapy orientated to pain and function was used. Results. In control groups where traditional immobilization with RICE method was used, pain decreased to 1.96 ± 1.33 points, in the intervention groups who had early physiotherapy and RICE method, pain decreased to 1.53 ± 1.23 points. Effect size in control groups was r = 0.55 points, in the intervention groups it was r = 0.54 points. In control groups who had traditional immobilization with RICE method, function increased to 68.67 ± 16.79 point, in the intervention groups who had early physiotherapy and RICE method, function increased to 75.61 ± 13.27 points. Effect size in control groups was r = 0.82 points, in the intervention groups r = 0.88 point. Conclusions. Early physiotherapy orientated to pain and functions after lateral ankle ligaments injury helps to reduce pain faster and increases function, and helps return back to work and sports activities.Keywords: lateral ankle ligament, injuries, early physiotherapy.

Chronische Beschwerden

Auch für schwere Distorsionen des oberen Sprunggelenkes (OSG) ist nach dem Ausschluss von Frakturen die möglichst frühzeitige funktionelle Behandlung Therapie der Wahl. Die Prognose der Verletzung ist gut, chronische Beschwerden und Instabilität sind eher selten und zudem unabhängig vom initialen therapeutischen Vorgehen. In solchen Fällen bedarf es weiterer Diagnostik (MRI) und eventuell sekundärer Stabilisation in einer Fachklinik. Eine Indikation zur Operation gibt es nur in wenigen Ausnahmefällen.
