Platelet-Rich Plasma Improves Strength and Speed of Recovery in an Active-Duty Soldier with Isolated Injury to the Lateral Collateral Ligament of the Knee: A Case Report.

Ligamentous injuries of the knee occur in the military, but constitute an overwhelmingly disproportionate number of medical discharges, which can be due to prolonged recovery through traditional use of physical therapy (PT) and other non-operative modalities. The use of platelet-rich plasma (PRP) may substantially increase the speed of recovery and patient outcomes but is little explored for less common isolated ligamentous injuries, such as the lateral collateral ligament, especially in active-duty populations. We describe the use of PRP in a young, otherwise healthy active-duty male to treat an isolated LCL injury with significant positive outcomes. These findings support consideration for early use of PRP in similar cases to improve recovery timelines and aid in return to duty.

Immediate Effects of Long-Axis Talocrural Thrust Manipulation on the Length of the Anterior Talofibular and Calcaneofibular Ligaments Measured With Musculoskeletal Ultrasound Imaging.

OBJECTIVE: The aim of the present study was to measure the immediate effect of a thrust manipulation on the length of the anterior talofibular and calcaneofibular ligaments in healthy patients. METHODS: A convenience sample of 47 healthy patients were recruited for this quasi-experimental study. The patients had an age range from 22 to 54 years, with a mean age of 30.36 years. There were 23 female patients and 24 male patients. Musculoskeletal ultrasound imaging was used to measure the length of the anterior talofibular and calcaneofibular ligaments before and immediately after a high-velocity long-axis thrust manipulation of the talocrural joint during various validated test positions. RESULTS: A single long-axis thrust manipulation did not result in a significant change in the length of the anterior talofibular ligament (P = .325). Additionally, there was no significant difference in calcaneofibular length after a long-axis thrust manipulation (P = .26). CONCLUSION: The results indicate that the length of the anterior talofibular and calcaneofibular ligament did not significantly change after a single long-axis thrust manipulation of the talocrural joint in healthy patients. It appears that the joint capsule of the talocrural joint reached end-range during the manipulation before the ligament undergoes plastic length changes; thus, the increase in joint range of motion after a thrust manipulation was probably not due to increased plastic length changes of the anterior talofibular and calcaneofibular ligaments.

Revision Lateral Ankle Reconstruction 40 Years After Chrisman-Snook Procedure: A Case Report.

CASE: A 70-year-old active woman presented with lateral ankle instability 40 years after a lateral ankle reconstruction procedure. Examination demonstrated gross instability, and advanced imaging revealed attenuation of her previous graft. She underwent anatomic reconstruction through a modified Brostrom-Gould technique and was able to return to hiking without pain. CONCLUSION: Recurrent lateral ankle instability after reconstruction represents a unique challenge for orthopaedic surgeons. Utilization of a modified Brostrom-Gould procedure with suture tape augmentation is a promising alternative to allograft or autograft reconstruction for patients with active lifestyle goals in the context of recurrent instability.

[Biomechanical analysis of ankle-foot complex during a typical Tai Chi movement-Brush Knee and Twist Step].

The purpose of this study is to analyze the biomechanics of ankle cartilage and ligaments during a typical Tai Chi movement-Brush Knee and Twist Step (BKTS). The kinematic and kinetic data were acquired in one experienced male Tai Chi practitioner while performing BKTS and in normal walking. The measured parameters were used as loading and boundary conditions for further finite element analysis. This study showed that the contact stress of the ankle joint during BKTS was generally less than that during walking. However, the maximum tensile force of the anterior talofibular ligament, the calcaneofibular ligament and the posterior talofibular ligament during BKTS was 130 N, 169 N and 89 N, respectively, while it was only 57 N, 119 N and 48 N during walking. Therefore, patients with arthritis of the ankle can properly practice Tai Chi. Practitioners with sprained lateral ligaments of the ankle joint were suggested to properly reduce the ankle movement range during BKTS.

Regeneration of grade 3 ankle sprain, using the recombinant human amelogenin protein (rHAM+ ) in a rat model.

Lateral ligament tears, also known as high-grade ankle sprains, are common, debilitating, and usually heal slowly. Ten to thirty percent of patients continue to suffer from chronic pain and ankle instability even after 3 to 9 months. Previously, we showed that the recombinant human amelogenin (rHAM+ ) induced regeneration of fully transected rat medial collateral ligament, a common proof-of-concept model. Our aim was to evaluate whether rHAM+ can regenerate torn ankle calcaneofibular ligament (CFL), an important component of the lateral ankle stabilizers. Right CFLs of Sabra rats were transected and treated with 0, 0.5, or 1 µg/µL rHAM+ dissolved in propylene glycol alginate (PGA). Results were compared with the normal group, without surgery. Healing was evaluated 12 weeks after treatment by mechanical testing (ratio between the right and left, untransected ligaments of the same rat), and histology including immunohistochemical staining of collagen I and S100. The mechanical properties, structure, and composition of transected ligaments treated with 0.5 µg/µL rHAM+ (experimental) were similar to untransected ligaments. PGA (control) treated ligaments were much weaker, lax, and unorganized compared with untransected ligaments. Treatment with 1 µg/µL rHAM+ was not as efficient as 0.5 µg/µL rHAM+ . Normal arrangement of collagen I fibers and of proprioceptive nerve endings, parallel to the direction of the force, was detected in ligaments treated with 0.5 µg/µL rHAM+ , and scattered arrangement, resembling scar tissue, in control ligaments. In conclusion, we showed that rHAM+ induced significant mechanical and structural regeneration of torn rat CFLs, which might be translated into treatment for grades 2 and 3 ankle sprain injuries.

A qualitative study of health professions curricula and management of lateral ankle ligament sprain demonstrates inconsistency.

BACKGROUND: Health educators aim to graduate students who are safe, effective and practice evidence-based medicine (EBM). Clinical Practice Guidelines (CPGs) are tools for translating evidence into clinical practice for health professionals and educators who lack time to appraise the evidence. There have been CPGs published for lateral ankle ligament sprains (LALS) for physiotherapists, nurses, and doctors. Clinical decision rules have also been developed for LALS to increase the safety of practice. The Ottawa Ankle Rules (OAR) were developed to screen for the need for an x-ray following an ankle or foot injury. METHODS: Educators from the Australasian College of Sports and Exercise Physicians (ACSEP), St John Ambulance first aiders, pharmacy, nursing, and physiotherapy disciplines were participants in this study. Using purposeful sampling with semi-structured questions and a LALS case study, 19 Australian educators were interviewed. Curricula and textbooks were also collected and analysed. Two researchers independently analysed the data using a deductive method. RESULTS: Analysis found that no educator used a CPG to inform their teaching. There was no common LALS curriculum for the five groups studied. There were two approaches: a triage curriculum (St John Ambulance, pharmacy, nursing) and a reflective curriculum (ASCEP and physiotherapy). Textbooks influenced curriculum for physiotherapy, pharmacy and first aid educators. The triage curricula recommend rest, ice, compression and elevation (RICE) alone, while the reflective curricula uses OAR, RICE, immobilisation if the LALS is severe, functional support (brace), exercises and manual therapy. In addition, ACSEP and physiotherapy do not recommend electrotherapy. All five groups were cautious about the use of non-steroidal anti-inflammatory drugs (NSAIDs). CONCLUSIONS: Physiotherapy and ACSEP educators teach OAR. Despite not using the CPGs to inform curriculum, physiotherapy and ACSEP have unintentionally aligned their curriculum with current LALS CPG recommendations. However, nursing, pharmacy and first aid trainers are not teaching OAR or aligned with LALS CPGs. Educators in pharmacy, nursing and first aid should re-examine their curricula and consider possibly teaching OAR and using CPG. Clinical practice guideline developers should consider pharmacists and first aiders as users of their LALS CPGs.

Stener-like lesion of the lateral collateral ligament of the first metatarsophalangeal joint.

Displaced ulnar collateral ligament injuries of the metacarpophalangeal joint of the thumb, also known as Stener lesions, are a well-recognized clinical entity, requiring surgical intervention because of the trapped location of the torn lateral collateral ligament superficial to the adductor aponeurosis of the thumb. We report a similar lesion located at the first metatarsophalangeal joint, to our knowledge the first ever described in the literature. In our patient, magnetic resonance imaging showed a full-thickness tear of the lateral collateral ligament of the first metatarsophalangeal joint, as well as a full-thickness tear of the extensor hood, with dislocation of the proximal part of the ruptured lateral collateral ligament to a position superficial to the extensor hood. Analogous to true Stener lesions, we are convinced these patients also need early surgical repair. Therefore, we would like to raise awareness about their existence to ensure adequate management of these lesions, in order to prevent possible long-term complications like chronic pain, instability, and joint degeneration.

[Efficacy of Shangbai ointment in alleviating pain in patients with acute ankle joint lateral collateral ligament injury: a randomized controlled trial].

OBJECTIVE: To investigate the effect of Shangbai ointment in relieving pain in patients with acute ankle joint lateral collateral ligament injury. METHODS: Fifty patients with unilateral ankle injury were randomized into Shangbai ointment treatment group and control group (n=25). The Visual Analog Scale (VAS) pain scores, ankle joint circumference, Kofoed score and self-rated lower limb function were recorded before and at 3, 7, and 14 days after the treatment. RESULTS: The baseline data were comparable between the two groups. The VAS pain score and swelling elimination in the treatment group were better than those in the control group at 3, 7, and 14 days after treatment; the Kofoed ankle score was higher in the treatment group than in the control group at 7 and 14 days after treatment. The patients in the treatment also reported better self-rated lower limb function than those in the control group at 7 and 14 days after the treatment. CONCLUSION: Shangbai ointment treatment can rapidly relieve pain in patients with acute ankle joint lateral collateral ligament injury and improve the functional scores of the joint.

Lateral collateral ligament reconstruction for chronic varus instability of the hallux interphalangeal joint.

Chronic varus instability of the hallux interphalangeal joint is a rare injury, and only a few reports of this injury have been published. In some studies, this injury has been related to taekwondo. Taekwondo is an essential martial art in the Korean military. We have described a case of varus instability of the hallux interphalangeal joint in a professional soldier who had practiced taekwondo for 5 years and the surgical outcome after reconstruction of the lateral collateral ligament with the fourth toe extensor tendon.

Isolated plantar dislocation of the 1st metatarsophalangeal joint.

Plantar dislocation of the 1st metatarsophalangeal joint is an extremely rare injury. To the best of our knowledge, there are no previous reports in the literature of an isolated dislocation of this type requiring open reduction and surgical repair. In this case report, we describe the clinical and operative findings and discuss in detail our surgical technique for the successful management of this unusual injury.

Ankle sprain.

INTRODUCTION: Injury of the lateral ligament complex of the ankle joint occurs in about one in 10,000 people a day, accounting for a quarter of all sports injuries. METHODS AND OUTCOMES: We conducted a systematic review and aimed to answer the following clinical question: What are the effects of treatment strategies for acute ankle ligament ruptures? We searched: Medline, Embase, The Cochrane Library, and other important databases up to November 2009 (Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). RESULTS: We found 38 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. CONCLUSIONS: In this systematic review we present information relating to the effectiveness and safety of the following interventions: cold treatment, diathermy, functional treatment, homeopathic ointment, immobilisation, physiotherapy, surgery, and ultrasound.

A double blind, randomised, parallel group study on the efficacy and safety of treating acute lateral ankle sprain with oral hydrolytic enzymes.

OBJECTIVE: To compare the effectiveness and safety of the triple combination Phlogenzym (rutoside, bromelain, and trypsin) with double combinations, the single substances, and placebo. DESIGN: Multinational, multicentre, double blind, randomised, parallel group design with eight groups structured according to a factorial design. SETTING: Orthopaedic surgery and emergency departments in 27 European hospitals. PARTICIPANTS: A total of 721 patients aged 16-53 years presenting with acute unilateral sprain of the lateral ankle joint. PRIMARY EFFICACY CRITERIA: (a) Pain on walking one or two steps, as defined by the patient on a visual analogue scale. (b) The range of motion, as measured by the investigator and expressed as a sum of flexion and extension. (c) The volume of the injured ankle measured with a volometer. RESULTS: At the primary end point at seven days, the greatest reduction in pain was in the bromelain/trypsin group (73.7%). The Phlogenzym group showed a median reduction of 60.3%, and the placebo group showed a median reduction of 73.3%. The largest increase in range of motion (median) was in the placebo group (60% change from baseline). The Phlogenzym group showed a median increase of 42.9%. The biggest decrease in swelling was in the trypsin group (3.9% change from baseline). The Phlogenzym group showed a -2.30% change from baseline and the placebo group a -2.90% change. In the subgroup analysis of patients who did not use a Caligamed brace, Phlogenzym was superior to placebo for the summarising directional test of the primary efficacy criteria (MW = 0.621; LB-CI 0.496; p = 0.029; one sided Wei-Lachin procedure). The vast majority of doctors and patients rated the tolerability of all treatments tested as very good or at least good. CONCLUSIONS: Phlogenzym was not found to be superior to the three two-drug combinations, the three single substances, or placebo for treatment of patients with acute unilateral sprain of the lateral ankle joint. The small subgroup of patients treated without the support of a Caligamed brace showed evidence of superiority of Phlogenzym over placebo. Further research is warranted to study this effect of Phlogenzym in patients treated without ankle support.
