The anterior cruciate ligament (ACL) together with the posterior cruciate ligament is the central stabilizer of the knee. It stabilizes the tibia against increased anterior translation and internal rotation. With an incidence of 46/100,000 ACL tears are among the most common sports injuries in Germany. New prevention programs can reduce the risk of ACL injuries. Surgical treatment is recommended for young and athletic patients as it can also reduce the risk of further relevant injuries of the meniscus and cartilage. The standard of surgical treatment in Germany is the ACL reconstruction with an autologous tendon graft. In selected cases, the preservation of the ACL by arthroscopic refixation shows good results. Instead of the previously used purely time-based rehabilitation, function-based criteria are increasingly being included in the aftercare.

Review
Viral anterior uveitis (VAU) needs to be suspected in anterior uveitis (AU) associated with elevated intraocular pressure, corneal involvement, and iris atrophic changes. Common etiologies of VAU include herpes simplex, varicella-zoster, cytomegalovirus, and rubella virus. Clinical presentations can vary from granulomatous AU with corneal involvement, Posner-Schlossman syndrome, Fuchs uveitis syndrome, and endothelitis. Due to overlapping clinical manifestations between the different viruses, diagnostic tests like polymerase chain reaction and Goldmann-Witmer coefficient analysis on the aqueous humor may help in identifying etiology to plan and monitor treatment.

Review
The increasing incidence of anterior cruciate ligament injuries in skeletally immature children demands careful attention by orthopedic surgeons. Assessing skeletal age is essential to selecting the appropriate reconstruction technique. Males with a bone age of 15 years or older and females of 13 years and older are ideal candidates for a transphyseal anterior cruciate ligament reconstruction because there is minimal risk of growth disturbance. Children with substantial growth remaining (skeletal age males ≤12 years and females ≤10 years) seem to be at risk for more significant growth disturbance, so we generally recommend physeal-sparing techniques for these younger patients.

Review
There has been steady progress in understanding the pathogenesis, clinical features, and effective treatment of acute anterior uveitis (AU) over the past 5 years. Large gene wide association studies have confirmed that AU is a polygenic disease, with overlaps with the seronegative arthropathies and inflammatory bowel diseases, associations that have been repeatedly confirmed in clinical studies. The role of the microbiome in AU has received increased research attention, with recent evidence indicating that human leukocyte antigen B27 (HLA B27) may influence the composition of the gut microbiome in experimental animals. Extensive clinical investigations have confirmed the typical features of acute AU (AAU) and its response to topical, regional and systemic immunosuppressive treatment. Increased understanding of the role of cytokines has resulted in studies confirming the value of anti-cytokine therapy [anti-tumor necrosis factor (anti-TNF) and interleukin 6 (IL-6) therapy] in severe and recurrent cases of AAU, particularly in subjects with an associated spondyloarthopathy (SpA) and in juvenile idiopathic arthritis (JIA)-associated AAU.

Review
Surgical reconstruction in anterior cruciate ligament (ACL) ruptures has proven to be a highly effective technique that usually provides satisfactory results. However, despite the majority of patients recovering their function after this procedure, ACL reconstruction (ACLR) is still imperfect. To improve these results, various biological augmentation (BA) techniques have been employed mostly in animal models. They include: (1) growth factors (bone morphogenetic protein, epidermal growth factor, granulocyte colony-stimulating factor, basic fibroblast growth factor, transforming growth factor-β, hepatocyte growth factor, vascular endothelial growth factor, and platelet concentrates such as platelet-rich plasma, fibrin clot, and autologous conditioned serum), (2) mesenchymal stem cells, (3) autologous tissue, (4) various pharmaceuticals (matrix metalloproteinase-inhibitor alpha-2-macroglobulin bisphosphonates), (5) biophysical/environmental methods (hyperbaric oxygen, low-intensity pulsed ultrasound, extracorporeal shockwave therapy), (6) biomaterials (fixation methods, biological coatings, biosynthetic bone substitutes, osteoconductive materials), and (7) gene therapy. All of them have shown good results in experimental studies; however, the clinical studies on BA published so far are highly heterogeneous and have a low degree of evidence. The most widely used technique to date is platelet-rich plasma. My position is that orthopedic surgeons must be very cautious when considering using PRP or other BA methods in ACLR.

Differential diagnosis of viral anterior uveitis (AU) based on the typical clinical findings (anterior chamber inflammation, morphology of the keratic precipitates, severity of IOP increase in relapse) is often straightforward. When differential diagnosis is difficult clinically, analysis of aqueous humour by PCR and/or antibody testing (Goldmann-Witmer coefficient) may be helpful. While both modalities are highly specific, they lack absolute sensitivity. Patients with HSV, VZV and CMV associated uveitis require both antiviral as well as antiinflammatory medication and often additional antiglaucomatous therapy, depending on IOP. In contrast, specific antiviral treatment is not possible in rubella associated AU and steroids should be administered with extreme caution due to their adverse effects. With all subtypes of virus associated AU, recurrent episodes put the patients at risk of developing secondary glaucoma, which often requires surgical treatment.

Review
Cytomegalovirus anterior uveitis is the most common ocular inflammatory disease caused by cytomegalovirus infection. It mainly occurs in middle-aged males with competent immunologic function, and the incidence is higher in Asia. The clinical manifestations vary from Posner-Schlossman syndrome and corneal endotheliitis to Fuchs uveitis syndrome, and are often accompanied by intraocular hypertension. Secondary glaucoma is a potentially blinding ocular complication with a pathogenesis that includes complicated immunological factors, intraocular inflammation, different types of angle abnormalities, and the administration of steroids, which may result in physical discomfort and visual impairment. Diagnostic tests, such as the polymerase chain reaction, optical coherence tomography, ocular microscopy, and confocal microscopy, might help in identifying anterior uveitis caused by other viruses. Combinations of antiviral medications and anti-inflammatory agents are effective treatments. If pharmacological therapy cannot reduce intraocular pressure or slow the progression of glaucomatous optic neuropathy, surgical intervention is required as a last resort.

PURPOSE
Oleander is a poisonous plant with extensively documented systemic side effects; however, oleander's ophthalmic side effects have not been detailed in the literature. We report a case of oleander-associated keratitis with subsequent corneal edema and anterior uveitis.
METHODS
This is a case report and review of relevant literature.
RESULTS
A 58-year-old woman presented with large corneal epithelial defect after being struck in the eye with an oleander leaf. Despite treatment with topical moxifloxacin, she developed severe corneal edema and anterior uveitis. A diagnosis of oleander-associated ocular inflammation with secondary corneal edema was made, given the temporal relationship, and treatment was initiated with topical prednisolone and cyclopentolate. However, the corneal edema and inflammation continued to progress until oral prednisone and topical difluprednate were initiated. Visual acuity, anterior uveitis, and corneal edema significantly improved with aggressive immunomodulation. Follow-up at 1 month confirmed complete recovery of symptoms, corneal edema and anterior uveitis.
CONCLUSIONS
Severe corneal edema and anterior uveitis can be associated with oleander exposure. Aggressive treatment with oral and topical steroids may be required without persistent sequelae at the 5-month follow-up. Ophthalmologists should consider this inflammatory reaction if patients experience ocular exposure to oleander.
