General principles of cartilage repair therapies have not changed in the last years. Recommendations for cartilage repair include symptomatic ICRS grade 3 and 4 classified cartilage defects. However, what has changed in the last years is a better understanding of underlying or concomitant pathologies. Since a more precise analysis and stringent therapy of concomitant pathologies has been performed, an increase in success rates especially in formerly difficult entities could be observed. The most important concomitant pathologies in cartilage therapies of the hip-, knee- and ankle joint are axis deviations, instabilities, meniscus pathologies or prearthrotic deformities like hip dysplasia and femuroacetabular impingement syndrome. To increase the efficiency of cartilage repair procedures these pathologies should be corrected either prior to, or at latest concomitant to any cartilage repair surgery. Therefore, this article is intended to give an overview of the most important concomitant pathologies in cartilage repair of the lower extremities and their possibilities of correction.

Intraligamentous injuries to the anterior cruciate ligament (ACL) and meniscus injuries are rare in children and adolescents and often occur as a result of sports injuries. Clinically, they usually present as a hemarthrosis. The diagnosis of choice is the MRI examination. Surgical treatment of intraligamentary ACL injuries using the transphyseal technique is now also the gold standard treatment for children and adolescents, leg axis and length checks are necessary after surgery until growth is complete. Meniscus injuries are also addressed surgically. Postoperative follow-up treatment and rehabilitation are particularly important in order to prevent reinjury. The disc meniscus is a special entity and is also treated surgically if it is symptomatic. Isolated collateral ligament and posterior cruciate ligament ruptures are rarities., (© 2024.

Background: Knee joint injuries are a regular and serious injury in football, often resulting in a long period of absence for players and are, therefore, a significant disadvantage for clubs. The various structures of the knee joint, such as ligaments, meniscus or cartilage, are exposed to the risk of injury due to different sport-specific situations in football and require different and specific therapeutic approaches for their adequate healing., Treatment: Both surgical and conservative treatment measures have been well investigated scientifically, especially for knee joint injuries in football, so that a successful and sustainable return to play on field is highly possible. Only in professional football is there a deviation from the usual standard of treatment in special situations in order to meet the demands and goals of professional footballers. In order to do address different subpopulations in football in the various injury types, both in treatment and in the return to play decision and, thus, sustainable secondary prevention, in addition to knowledge of scientific evidence on knee joint injuries, basic experience in the sport in which the patients with knee joint injuries are active is also useful., (© 2024.

Objective: Reduction of increased reclination of the tibial plateau (posterior slope) to improve the anterior stability of the knee joint., Indications: Increased posterior reclination of the tibial plateau greater than 12° in combination with recurrent instability after anterior cruciate ligament (ACL) reconstruction., Contraindications: Hyperextension of more than 15° (relative)., Surgical Technique: Anterior skin incision approximately 8-10 cm above the tibial tuberosity. Insertion of two converging guidewires directly below the patellar tendon ending obliquely in the area of the posterior cruciate ligament (PCL) insertion. Control of the wire position with the image intensifier core. Oscillating saw osteotomy. Removal of the wedge and closure of the osteotomy. Osteosynthesis with interfragmentary screw and medial angle-stable plate., Postoperative Management: Partial load with 10-20 kg for 2 weeks, then step by step increase in load. Mobility: free., Results: To date we have operated on 36 patients with recurrent instability after ACL reconstruction (20 men, 16 women, average age 34.4 years) in the manner described in this article. In 25 cases, enlarged bone tunnels were filled with allogeneic bone at the same time. The posterior slope of the tibial plateau could be reduced from an average of 14.5° to 8.8°. In 28 cases another ACL reconstruction was performed after an interval of 4-12 months. The Lysholm score significantly increased from 76.3 points to 89.2 points., (© 2024.

Background: Partial knee replacement has proven to be an effective therapy for advanced unicompartmental arthrosis of the knee. Despite continuous advancements in implants and surgical techniques over the past decades, the global preference for total knee arthroplasty still persists for historical reasons., Objectives: This report aims to illuminate advantages and disadvantages of partial knee replacement considering long-term results, the evolution of indication criteria over recent decades and new aspects in patient selection with potential improvements through emerging technologies., Material and Methods: The analysis involves the examination of long-term results from clinical studies and registry data, highlighting the risk factors for potential failures and their influence on the development of indication criteria., Results: Present-day long-term results demonstrate excellent prosthetic survival, aligning with outcomes from total knee arthroplasty. New perspectives for expanding indication criteria are discussed, including the possible application of partial knee replacement in cases of severe varus deformity > 15°, anterior cruciate ligament insufficiency, young active patients, anterior knee pain, and/or patellofemoral arthritis, as well as mild radiographic arthritis with degenerative medial meniscus root tear and meniscal extrusion., Discussion: Indication criteria have consistently expanded in recent years, taking into account modern insights, and the application of advanced technologies can enhance precision and minimize surgical errors. Furthermore, this report emphasizes that revision rates are not the sole criterion for success and underscores the necessity for a comprehensive examination of clinical results., (© 2024.

Anterior cruciate ligament (ACL) ruptures are the second most common sports injury after ankle injuries and most commonly lead to surgical treatment compared to all sports injuries. Rupture of the ACL is accompanied by increased anteromedial rotational translation of the lower leg relative to the upper leg. The consequence is a subjective sense of instability as well as an objective instability in clinical testing. The ACL reconstruction procedure has become the gold standard of surgical treatment. Despite the substantial literature available, there is controversy regarding the timing of the operation, techniques of surgical treatment, choice of suitable graft and fixation. Based on the current literature, this article aims to demonstrate the evidence of these points and to provide guidance on the optimal treatment of each individual patient considering the individual context factors. [ABSTRACT FROM AUTHOR]

In recent years biomechanical and clinical studies have shown that the three-dimensional bony alignment of the lower extremities has a relevant influence on the ligamentous structures of the knee and consequently on the stability of the knee joint. Therefore, in the case of pathological ligamentous damage of the knee joint, a possible malalignment must always be thoroughly evaluated and if necessary, included in the treatment planning. Varus malalignment plays an important role especially with respect to the cruciate ligaments as well as the posterolateral ligamentous structures and has been identified as a significant risk factor for failure after surgical reconstruction of these ligamentous structures. Similar data have also been published for valgus malalignment particularly with respect to its negative influence on the anterior cruciate ligament and the medial capsuloligamentous complex. Alignment deviations in the sagittal plane, especially the inclination of the tibial articular surface (slope), have been extensively investigated in several recent studies. It has been demonstrated that the tibial slope has a relevant influence on the anteroposterior stability of the knee joint and hence on the cruciate ligaments. First clinical studies on the surgical correction of the axis in selected patients showed very promising results with the potential of protecting ligament reconstructions against repeated failure; however, further data especially regarding the importance and the exact indications for an additional alignment correction are necessary., (© 2023.

Introduction: The purpose of this study was to investigate the intertester reliability and validity of the Lever Sign Test. Intertester reliability has received little attention in previous studies. In order to make comparisons with other studies, the intertester reliability and validity of the Lachman and Anterior Drawer Tests were also calculated., Patients/material and Methods: Patients between 18 and 50 years of age with suspected ligament and/or meniscus injuries were included. Exclusion criteria were suspected malignant, systemic, or central neurologic disease, acute cartilage injury, suspected fracture, or knowledge of the participant's knee findings. Testing was randomized and blinded by an experienced orthopaedic surgeon and a physical therapist. Cohen's kappa was calculated for intertester reliability. Sensitivity and specificity, positive and negative predictive value, and positive and negative likelihood ratio were calculated. MRI findings were used as the gold standard., Results: Thirty-six patients were enrolled in the study, 27 male (75%) and 9 female (25%). The prevalence of anterior cruciate ligament lesions was 44.4%. Cohen's kappa (κ) was κ=0.6 (CI 95% [0.29, 0.91]) for the Lever Sign Test, κ=0.64 (CI 95% [0.35, 0.93]) for the Lachman test, and κ=0.63 (CI 95% [0.3, 0.95]) for the Anterior Drawer Test. The sensitivity of the Lever Sign Test was 0.53 and 0.40 for the orthopaedic surgeon and physical therapist, respectively, specificity was 0.89 and 0.79, the positive predictive value was 0.80 and 0.60, the negative predictive value was 0.70 and 0.62, the positive likelihood ratio was 4.80 and 1.90, respectively, and the negative likelihood ratio was 0.76 and 0.53., Conclusion: The estimated intertester reliability of the Lever Sign Test was good. The Lever Sign Test is suitable as a complement to the Lachman Test, which is considered the most valid test in the literature. The weaknesses and ambiguities of the operating mechanism of the Lever Sign Test should not be ignored and should be further explored., Competing Interests: Die Autorinnen/Autoren geben an, dass kein Interessenkonflikt besteht., (Thieme.

Background: Knee dislocation (KD) is a rare but severe injury of the knee joint, with a high rate of concomitant neurovascular injuries. The severity of the ligamentous injury, which is classified according to the Schenck classification, the mechanism of injury, concomitant injuries and individual factors determine the treatment strategy in KD., Treatment Strategy: Furthermore, a clear differentiation between high-velocity (HV) and low-velocity (LV) injuries is necessary. Generally, surgical treatment within 7-10 days should be aspired. Herein, the one-stage hybrid treatment using augmented ligament sutures (ligament bracing) in combination with primary ligament reconstruction (posterolateral and ACL) leads to very good functional results in the mid-term. Ultra-low-velocity (ULV) dislocations and those with concomitant peroneal lesions require a modified approach, due to a limited prognosis. During rehabilitation, the individual progress must be closely monitored and follow an early functional approach. In approximately 20% of all cases, early arthroscopic arthrolysis shows a high success rate., (© 2023.

Zusammenfassung Die vordere Kreuzband (VKB)-Ruptur ist eine der schwerwiegendsten Verletzungen im Judo. Präventionsprogramme scheinen sinnvoll. Die Indikation operativer Therapie sollte großzügig gestellt werden. Das Risiko für vorzeitigen Gelenkverschleiß und Reduktion der sportlichen Leistungsfähigkeit ist hoch. Für erwachsene Judoka im Hochleistungsbereich kann unter bestimmten Umständen eine konservative Therapie infrage kommen. Beispiele von Spitzenathleten zeigen, dass teilweise trotz Kniegelenksinstabilität Höchstleistungen erbracht werden können. Das therapeutische Vorgehen und die zu erwartenden Konsequenzen sollten in diesen Fällen eng abgestimmt werden. Es existieren Hinweise, dass Hamstings als Transplantat für Judoka nachteilig sein können. Summary The anterior cruciate ligament (ACL) rupture is one of the most serious injuries in judo. The development of prevention programs seems reasonable. The indication for surgical therapy should be generous. The risk of post-traumatic degenerative joint changes, and reduction of athletic performance is high. For judo athletes on the highest performance level, a conservative therapy may be considered under certain circumstances. Recent examples of top athletes show that in some cases, high performance can be delivered despite knee joint instability. In these cases the therapeutic approach and the expected consequences should be closely coordinated. Hamstring tendon grafts could be detrimental for judoka. [ABSTRACT FROM AUTHOR]

Zusammenfassung Für die Entwicklung der posttraumatischen Gonarthrose nach VKB-Ruptur spielen primäre und sekundäre Meniskusschäden eine wichtige Rolle. Eine persistierende, chronische Instabilität nach vorderer Kreuzbandruptur kann mittel- bis langfristig zu sekundären Meniskus- und Knorpelschäden führen. Eine VKB-Plastik schützt vor sekundären Meniskusschäden. Außerdem liegt wissenschaftliche Evidenz vor, dass eine VKB-Plastik langfristig auch die Entstehung einer posttraumatischen Gonarthrose verhindern kann. Das gilt besonders für Kniegelenke, bei denen es schon zu einem Meniskusschaden gekommen ist. Summary For the development of post-traumatic osteoarthritis after ACL rupture, primary and secondary meniscal damages play an important role. Chronic instability after anterior cruciate ligament rupture leads to secondary meniscus and cartilage damage in the long term. An ACL reconstruction protects the knee against secondary meniscal damage. In addition, there is scientific evidence that ACL reconstruction can also prevent the development of post-traumatic osteoarthritis in the long term. This is especially true for knee joints, which have already suffered meniscal damage. [ABSTRACT FROM AUTHOR]
