- Abstract
Background: The triangular fibrocartilage complex (TFCC) widens the radiocarpal joint and takes part in load transmission from the carpus to the forearm. It is thereby prone to degenerative changes. The painful situation that can accompany degeneration is called ulnar impaction., Diagnosis: Clinical examination helps differentiate between various causes of ulnar-sided wrist pain. Standard X‑rays are needed to determine ulnar variance and stress radiographs can depict narrowing of the ulnocarpal joint space under load. MRI may prove degeneration of the TFCC itself or may indirectly confirm ulnar impaction in the presence of bone marrow edema in the ulnar head or at the proximal ulnar aspect of the lunate., Treatment: If conservative treatment fails to alleviate symptoms, arthroscopy may be indicated. On the one hand, this completes the diagnostic cascade, and, on the other hand, allows decompression of the ulnocarpal joint space by resection of the TFCC with partial resection of the ulnar head (wafer resection). In the case of ongoing pain, ulnar shortening sufficiently alleviates ulnar-sided wrist pain. Thereby, modern standardized operation techniques are safe enough to ensure bone healing at the osteotomy site. The aim of alleviating ulnar-sided wrist pain is mostly achieved if the correct treatment option is chosen.

- Abstract
The number of patients with meniscal injuries is increasing constantly, but the treatment algorithms are undergoing continuous change. The effects of meniscal surgery, as well as the indications for the procedure, are currently a matter of heated debate. Various German speaking associations addressing topics related to the knee have joined forces to develop guidelines for the diagnosis, evaluation and therapy of meniscal lesions. The hope is that this first of two publications will shed light on some of the ongoing issues and offer guidance to health care professionals treating these patients., (Georg Thieme Verlag KG Stuttgart · New York.)

- Abstract
Excellent morphological imaging of cartilage is now possible and allows the detection of subtle cartilage pathologies. Besides the standard 2D sequences, a multitude of 3D sequences are available for high-resolution cartilage imaging. The first part therefore deals with modern possibilities of morphological imaging. The second part deals with functional cartilage imaging with which it is possible to detect changes in cartilage composition and thus early osteoarthritis as well as to monitor biochemical changes after therapeutic interventions. Validated techniques such as delayed gadolinium-enhanced magnetic resonance imaging of cartilage (dGEMRIC) and T2 mapping as well the latest techniques, such as the glycosaminoglycan chemical exchange-dependent saturation transfer (gagCEST) technique will be discussed.

- Abstract
Aim: The aim of this study was to evaluate the progression of osteoarthritis (end-stage disease with a requirement for arthroplasty) in patients with focal cartilage defects of the medial knee compartment., Material and Methods: Patients (n = 115) with focal cartilage lesions of the medial knee compartment underwent arthroscopy. The follow-up was performed 10 years after the operation to determine the rate of arthroplasty conversion and to evaluate associated factors., Results: In a total of 35 cases an arthroplasty was needed (30.4 %). The mean survival to arthroplasty was 93.2 (95 % CI 85.4-109.0) months. Cartilage defects within the femur and cartilage lesions within the patella and the lateral did not influence the OA progression. Among the significant risk factors for OA progression were higher patient age, female gender, overweight or obesity and severity of meniscal damage. The most important risk factor was the occurrence and the extent of tibial cartilage defects., Conclusions: In the natural course, about 30 % of patients with focal cartilage defects of the medial knee compartment undergo rapid OA progression (arthroplasty as end-stage of the disease). There are general risk factors (age, female gender and obesity) but also local risk factors. Furthermore, tibial defects and the extent of meniscus loss influence the outcome significantly. These general and local factors should be more carefully estimated or addressed in future clinical and scientific work., (Georg Thieme Verlag KG Stuttgart · New York.)

- Abstract
Objective: The aim of our study was to implement and test an imaging protocol for the detection and evaluation of standardised cartilage defects using high-field magnetic resonance imaging (MRI) and to determine its limitations., Material and Method: A total of 84 cartilage defects were created in the femoral condyles of euthanized dogs with a minimum body mass of 25 kg. The cartilage defects had a depth of 0.3 to 1.0 mm and a diameter of 1 to 5 mm. T1-FLASH-3D-WE-sequences with an isotropic voxel size of 0.5 x 0.5 x 0.5 mm and an anisotropic voxel size of 0.3 x 0.3 x 0.8 mm were used. In addition to quantitative evaluation of the cartilage defects, the sig- nal intensities, signal-to-noise ratios and contrast-to-noise ratios of the cartilage were determined. Of special interest were the limita- tions in identifying and delineating the standardised cartilage defects., Results: With the anisotropic voxel size, more cartilage defects were detectable. Our results demonstrated that cartilage defects as small as 3.0 mm in diameter and 0.4 mm in depth were reliably detected using anisotropic settings. Cartilage defects below this size were not reliably detected., Conclusion and Clinical Relevance: We found that for optimal delineation of the joint cartilage and associated defects, a higher in-plane resolution with a larger slice thickness should be used, corresponding to the anisotropic settings employed in this study. For the delineation of larger cartilage defects, both the anisotropic and isotropic imaging methods can be used.

- Abstract
Damage to hyaline cartilage is the most important pathophysiological tool in the development of osteoarthritis. Cartilage lesions are the most frequent pathological findings during arthroscopic operations. Arthroscopies as well as magnetic resonance tomography are gold standards for detection of cartilage lesions. But the arthroscopic evaluation of cartilage lesions is descriptive and subjective only. The surgeon is able to differentiate between intact cartilage surface, softening, superficial or deep fissure or flake and finally a complete defect. In routine arthroscopy the grading mostly is made by use of different scores [e.g. ICRS (International Cartilage Repair Society), Outerbridge, Insall, Jäger-Wirth or others]. Because the arthroscopic evaluation is subjective the reliability of this method is poor. Spectroscopic methods are established for evaluation of different tissue diseases in different indications. NIRS (near infrared spectroscopy) has become an important method for medical diagnostics in the last years. NIR is very energy-rich and suitable for glass fibre transport without relevant reduction. Insofar this technology may be ideal for endoscopic procedures. Our systematic literature review reveals that NIRS is a sufficient method for an objective diagnosis of cartilage lesions. In the current work we demonstrate an NIRS-based device for intraoperative, real-time cartilage evaluation. Furthermore, we discuss the possible clinical consequences from such measurements., (Georg Thieme Verlag KG Stuttgart · New York.)

- Abstract
The article on chondrodermatitis nodularis chronica helicis summarizes various clinical pictures and differential diagnoses of this entity. This lesion is usually characterized by a solid or cystic nodule but ulcerations or crusts may also occur. The most common differential diagnoses include benign or malignant tumours, which are often confused with chondrodermatitis nodularis chronica helicis. The characteristic pain associated with this condition may serve as an important diagnostic clue in order to rule out other differential diagnoses. The therapy of chondrodermatitis nodularis chronica helices encompasses several conservative as well as surgical treatment options., (© The Authors • Journal compilation © Blackwell Verlag GmbH, Berlin.)

- Abstract
Background: Chondrodermatitis nodularis chronica helicis is a rather common condition which substantially affects quality of life causing pain and sleeping disturbances. Surgical treatment is connected with a tendency to recurrence. Mechanical pressure is probably the main etiological factor., Patients and Methods: A prospective study was performed with 18 patients that were offered a non-surgical treatment using a self-made bandage of foam plastic which they applied during the night. Of these, 12 performed the treatment including follow-up; 6 patients initially also consented, but they did not return after the initial visit., Results: 11 patients reported substantial reduction of pain within the first month; after an average of 1.75 months they were free of pain. All 8 patients with initial sleeping problems caused by pain reported undisturbed sleep after only one month. In 11 patients the lesions receded satisfactorily, in 9 patients completely, in 2 patients leaving small asymptomatic residual lesions. Recurrences appeared in 3 patients with 2 of them having been surgically pretreated at the same location., Conclusions: We recommend conservative treatment using protective padding as first line treatment for chondrodermatitis nodularis chronica helicis. The successful outcome achieved only by relief of pressure supports pressure as the main etiological factor in the development of the disease., (© The Authors • Journal compilation © Blackwell Verlag GmbH, Berlin.)

- Abstract
Chondral or osteochondral lesions are typical injuries in orthopaedics and traumatology. Since there is no regeneration of damaged articular cartilage, these lesions can lead to premature osteoarthritis. Therefore, an adequate therapy for these injuries is an important goal. Nowadays, common methods in cartilage therapy are procedures for the recruitment of mesenchymal stem cells: autologous osteochondral transplantation and autologous chondrocyte transplantation. Currently, autologous osteochondral transplantation is the only procedure that allows the replacement of the defect with hyaline cartilage. However, this procedure has the problem of donor-site morbidity and limited availability of transplants. Stem cell recruiting procedures and autologous chondrocyte transplantation normally achieve a regeneration of the defect with only fibrocartilage tissue, but both can achieve good medium-term clinical results. Each of these therapeutic principles has certain major indications. In order to select an adequate therapy, the classification of chondral or osteochondral lesion is needed. From a multiplicity of classification systems, those of the ICRS are of particular clinical relevance.

- Abstract
Background: The study was aimed to evaluate the validity of clinical, radiological and MRI examination for cartilage defects of the knee compared with arthroscopic finding., Methods: Seven-hundred seventy-two patients who were suffering from knee pain over more than 3 months were evaluated clinical (grinding-sign) and with radiography and magnetic resonance imaging (MRI) and subsequent arthroscopy., Results: The grinding sign had a sensitivity of 0.39. The association of a positive grinding test with high grade cartilage defects was significant (p<0.000). In 97.4% an intact chondral surface correlated with a normal radiological finding. Subchondral sclerosis, exophytes and a joint space narrowing was significantly associated with high grade cartilage defects (p<0.000). The accuracy of MRI was 59.5%. The MRI resulted in an overestimation in 36.6% and an underestimation in 3.9%. False-positive results were significant more often assessed in low-grade cartilage defects (p<0.000)., Conclusions: Clinical signs, x-ray imaging and MRI correlate with arthroscopic findings in cases of deep cartilage lesions. In intact or low-grade degenerated cartilage often results an overestimating of these findings.

- Abstract
The motivation for cartilage repair is the preservation of adequate joint motion. Repairing joint surface congruity and providing balanced load bearing are crucial for this. MRI can contribute to this goal by describing number, depth, size, and distribution of cartilage lesions throughout the different joint compartments. Essential to such a contribution are adequate spatial resolution at a reasonable SNR together with good contrast between both cartilage and the subchondral bone as well as the joint space. For TSE sequences, this is achieved using TEs between 30 and 50 ms. Diagnostic accuracy is optimal when a lesion is depicted in more than one plane. Short TE, high bandwidth, and the appropriate orientation of the frequency encoding direction contribute to minimizing metal artifacts. Besides internal alterations of the cartilage's matrix, moderately T2-weighted TSE sequences sensitively depict bone marrow edema such as signal alterations and joint effusion, both contributing to highlight even subtle cartilage lesions. T1-weighted FS/WE 3D GE sequences profit from their high spatial resolution to appreciate gradual erosion of the cartilage. In OD the interface to the surrounding bone, the integrity of the overlying cartilage, and associated cysts are used to determine stability. The presence of two or more findings increases diagnostic accuracy. Prognosis is associated with the size of the affected area.

- Abstract
Aim: Matrix-guided autologous chondrocyte implantation (MACI) was compared with microfracture (MFX) to demonstrate the reconstitution of cartilage over a two-year period using the morphological capabilities of MRI., Patients and Methods: 27 patients (9 females and 18 males, mean age 33 years) underwent MACI on the knee joint. The defects originated from trauma (15 cases), osteochondritis dissecans (8 cases) and chronic repetitive trauma (4 cases) and were localized at the condyles (24 cases) or patella (3 cases). All patients were examined postoperatively after 1, 3, 6, 12 and 24 months with a 1,5 T unit (Gyroscan, Philips) using proton- and T2w spinecho and T1w fatsuppressed 3D gradientecho sequences. We measured the signal intensities of the implant and neighbouring cartilage to calculate the contrast-to-noise ratio (CNR), and the thickness of cartilage and implant layers to define the defect filling rate. Finally, partial and complete remission was defined on MRI and compared with clinical data and morphology on MRI. Additionally, 7 patients were treated with MFX and, subsequently examined on MRI with the same protocol., Results: After MACI, MRI showed a partial but no complete equilibration of signal intensities of implant and adjacent cartilage over the 1 and 2 year follow-up periods which was shown by reduction of CNR from 21 to 10 on 3D-GE and from 26 to 9 on T2w SE sequences. Continuous growth of the implants resulted in an increased filling of the defects starting at 40% after 0.5 year to 85% after 1 or 2 years. Complete remission was found on MRI in 17/27 cases, and remission rate was influenced by etiology of cartilage defect but not by age and gender of patients or size and location of defects. The Lysholm-Gillquist score improved from 49.7 to 97.3. After MFX equilibration of signal intensities and growth of the regenerating fibrous cartilage was less pronounced and complete remission was found in only 2/7 cases. In addition, the clinical score improved from 45.5 to 74.2., Conclusion: Direct imaging of cartilage with MRI and assessment of clinical scores allowed improved documentation of the outcome after MACI and MFX. MRI showed that MACI is superior to MFX concerning rate of complete remissions and filling of the defect with regenerating tissue. Clinical examinations showed better scores for MACI than for MFX.

- Abstract
Over the past decade a number of surgical interventions for durable cartilage repair have been developed. For the long-term follow-up of this procedures clinical scores and the morphological and biochemical evaluation of biopsies taken during arthroscopy are used.Magnetic resonance imaging is a useful noninvasive tool for the evaluation of the morphologic status of the cartilage repair tissue throughout the postoperative period. The MR imaging appearance of the most important cartilage transplantation techniques, such as autologous osteochondral transplantation, autologous chondrocyte implantation and matrix-based autologous chondrocyte implantation are described and possible complications of each technique are mentioned. The importance of new MR techniques such as high-resolution morphologic imaging and possible visualization of biochemical information of cartilage repair tissue is discussed.

- Abstract
Lesions of the TFCC are currently a diagnostic and therapeutic challenge. Disc-injuries are often not identified and, therefore, acute ruptures are unfortunately not always immediately repaired. Moreover, therapeutic measures are still sparse and informative trial results are lacking. An anatomical, pathological, diagnostic and therapeutic comparison with the meniscus of the knee is possible.

- Abstract
Aim of the Study: We point out multiple applications of a gait laboratory in solving different problems in the children's orthopaedic field. With typical examples we show how biometrical data of the gait laboratory can be helpful to solve problems in orthopaedic examinations., Material and Method: The range of questions to be solved in the gait laboratory differs from individual diagnostic examinations of a patient up to the control of devices in the functional use at the patient. As a typical example for the individual examination we show the gait analysis in a 14-year-old girl with idiopathic chondrolysis of the hip joint. The functional use of orthopaedic devices will be shown in youths with neuroorthopaedic diseases. As a very special question to the gait lab we describe the supply of children and youths with optimal sport shoes for running., Results: The biometrical measurement techniques generate exact data to solve individual diagnostic and therapeutic questions. Orthopaedic devices can be tested in their functional efficiency and quality. Special questions can be answered very flexible., Conclusion: Diagnosis and therapy in orthopaedics and children's orthopaedics rely on exact data. However, details of the dynamics during movement are neither visible to the most experienced orthopaedic surgeon nor can they be documented by conventional diagnostic imaging procedures. The present technical potential of biometric assessment methods allow to precise and correct some empirical knowledge, they open a wide field of new applications in diagnostic and therapeutic examinations.

- Abstract
Purpose: Evaluation of TSE- and T 1 -3D-GRE-sequences for focal cartilage lesions in vitro in comparison to ultrahigh resolution multi-slice CT., Materials and Methods: Forty artificial cartilage lesions in ten bovine patellae were immersed in a solution of iodinated contrast medium and assessed with ultrahigh resolution multi-slice CT. Fat-suppressed TSE images with intermediate- and T 2 -weighting at a slice thickness of 2, 3 and 4 mm as well as fat-suppressed T 1 -weighted 3D-FLASH images with an effective slice thickness of 1, 2 and 3 mm were acquired at 1.5 T. After adding Gd-DTPA to the saline solution containing the patellae, the T 1 -weighted 3D-FLASH imaging was repeated., Results: All cartilage lesions were visualised and graded with ultrahigh resolution multi-slice CT. The TSE images had a higher sensitivity and a higher inter- and intraobserver kappa compared to the FLASH-sequences (TSE: 70 - 95 %; 0.82 - 0.83; 0.85 - 0.9; FLASH: 57.5 - 85 %; 0.53 - 0.72; 0.73 - 0.82, respectively). An increase in slice thickness decreased the sensitivity, whereby deep lesions were even reliably depicted on TSE images at a slice thickness of 3 and 4 mm. Adding Gd-DTPA to the saline solution increased the sensitivity by 10 % with no detectable advantage over the T 2 -weighted TSE images., Conclusion: TSE sequences and application of Gd-DTPA seemed to be superior to T 1 -weighted 3D-FLASH sequences without Gd-DTPA in the detection of focal cartilage lesions. The ultrahigh resolution multi-slice CT can serve as in vitro reference standard for focal cartilage lesions.

- Abstract
MR imaging has evolved to the best non-invasive method for the evaluation of articular cartilage. MR imaging helps to understand the structure and physiology of cartilage, and to diagnose cartilage lesions. Numerous studies have shown high accuracy and reliability concerning detection of cartilage lesions and early changes in both structure and biochemistry. High contrast-to-noise ratio and high spatial resolution are essential for analysis of articular cartilage. Fat-suppressed 3D-T1 weighted gradient echo and T2-weighted fast spin echo sequences with or without fat suppression are recommended for clinical routine. In this article the anatomy and pathology of hyaline articular cartilage and the complex imaging characteristics of hyaline cartilage will be discussed.

Included was an infant with hand changes 8 months after unwitnessed rat bites., Results: Each condition revealed findings consistent with the hypothesis of localized damage to sites of enchondral ossification, including at acrophyses--the growth plates that are not between epiphysis and metaphysis, but instead lie at the margins of growth centers, including carpal and tarsal bones, and the non-epiphyseal ends of small tubular bones., Discussion: The patterns observed support a final common pathway of damage in frostbite due to cold injury, Kashin-Beck disease (endemic in China) of unknown etiology, and damage from toxins associated, for example, with rat bite. In frostbite, the distribution is acral because of the site of exposure, while the distribution in Kashin-Beck is more diffuse and often less contiguous. In each condition, arthrotic sequelae may be expected in the natural course of follow-up. MRI may play a role in acute diagnosis that might modify the course of each disease.

- Abstract
Tibial torsion defects are usually not clinically evident and, hence, are often overlooked. Clinical examination and CT scan have proved to be the best ways of measuring static tibial torsion, whereas dynamic measurements are usually performed in the clinic and the "gait laboratory." Only few studies have determined there to be a connection between a torsion defect in the lower leg and expected pathological conditions of the knee and ankle joints. However, patellofemoral instability, Osgood-Schlatter disease, osteochondrosis dissecans are increasingly being found in cases of increased external tibial torsion and arthrosis in reduced torsion. Although spontaneous correction may occur in certain cases, in others the only way to correct the condition is by employing physiologic torsion. Conservative treatment methods such as bandages or orthosis have been shown to not have any effect on torsion; thus, surgical treatment is the only successful way to correct a pathologic angle of rotation of the tibia. For this, supramalleolar osteotomy with fixation using Kirscher wires and plaster or an external fixator are the most common treatments.

- Abstract
The human cartilage and bone is characterized by a remodeling during the life, well balanced by neosynthesis and degradation of matrix components. In different joint diseases, it becomes imbalanced and the destruction of the cartilage supersedes the repair. In tissue processes in disease and in normal turnover of the matrix, these molecules are fragmented and released into surrounding fluids, in the synovial fluid, and then in the blood and the urine, where they can be detected. The quantitative measurement in the synovial fluid is more specific than in the other body fluids. The research process in recent years has suggested that these molecular markers of cartilage and bone matrix metabolism can be used to determine diagnosis, the disease severity rather than its presence or absence, the prognosis, and the response to therapy. They should help to identify the disease mechanism in different joint diseases not only on the tissue but also on the molecular level. The specific cartilage matrix markers promise to become useful tools in the future in clinical use. The research in this area is still in the early stages, with most results dated from the end of the 1980s and the 1990s.

- Abstract
Lesions of human articular cartilage most often are the result of a pathogenetically unclear disease process eventually leading to primary osteoarthrosis. The increasing incidence of traumatic injuries during sport activities, leading to lesions of cartilage and bone, is also worth noting. In addition, osteochondrosis dissecans and hereditary dysplasias of the skeletal system may lead to osseous and cartilaginous lesions. Adult articular cartilage has only very limited repair capacity in response to acute and chronic insults. Even now, diagnostic tools and methods of diagnosing cartilaginous lesions are still far from accurate. Lesions seen by conventional imaging technology chiefly represent late and irreversible damage of joint cartilage structures. The present review first summarizes current basic knowledge of joint anatomy and physiology, to enable the reader to understand better the unique nature of cartilaginous lesions and the difficulties and controversies involved in old and novel experimental methodologies in cartilage repair. It then critically evaluates developments in orthopedic therapy for repair of articular cartilage lesions.

- Abstract
Purpose: An experimental study was performed on joint specimens of the knee to assess the advantages and disadvantages of 14 generally available sequences in cartilage imaging., Methods: Each of the 50 surgically exposed cadaveric joints of the knee was examined by the following sequences: T1, proton- and T2 weighted spin echo(SE) sequences, proton- and T2 weighted Turbo-SE, T1 weighted SE with fat suppression, MTC combined with T1-weighted SE and T2 weighted FLASH-2 D, STIR, FISP-3 D, FLASH-3 D (with fat suppression), and MR arthrography. We assessed the image quality by a scale, signal to noise-ratio of cartilage and joint fluid, and the accuracy in detection of cartilage lesions. Pathology and arthroscopy were reference methods to MRI, and demonstrated grade 1-4 lesions on 186 of 300 joint facettes., Results: Advanced stages of cartilage lesions (65 grade 3 and 4 lesions) were detected by standard SE sequences in 67-94%. Application of volume techniques (FISP-3 D, FLASH-3 D), high definition matrix (512 pixel), MTC with FLASH-2 D and MR-arthrography improved the sensitivity up to 82-100%. Superficial lesions (65 grade 2 lesions) were demonstrated in 3-38%, and on MR arthrography in 45%. Structural changes (56 Grade 1 lesions) were recorded on MR) in only 10%., Conclusions: With regard to standard SE sequences, the detectability of cartilage lesions can be improved by techniques that use 512 matrices, selective cartilage imaging, and volume acquisition.

- Abstract
Background: Relapsing polychondritis is a rare recurring inflammatory disorder with variable clinical course. Its etiopathogenesis is unknown, but autoimmune mechanisms are likely to be involved., Patient: We present a case report of a 42-year-old woman with polychondritis manifested in very slowly progressing destruction of the nasal cartilage, additional subglottic tracheal stenosis, and increasing cochlear dysfunction., Result: We describe and document by a series of photographs the very protracted course of the disease in this patient from early youth until now. Clinical signs and differential diagnosis in polychondritis are discussed., Conclusion: An early diagnosis in slowly progressing cases like this has to be established in order to permit adequate use of glucocorticoids and/or immunosuppressive drugs, to check the progress of the disease and prevent potentially lethal complications.

- Abstract
Standard radiographs still represent the standard imaging method in knee abnormalities. Major advantages include high spatial resolution, low cost, high availability and standardized imaging technique. Because there is an increasing pressure on the cost of health care, additional imaging should only be employed based on a working hypothesis. In most cases MR imaging is most suitable for further diagnosis. In internal knee derangements MR imaging has been shown to have a high negative predictive value, thus obviating unnecessary surgery. MR imaging also is the imaging method of choice in the detection and follow-up of arthritis, in the detection, staging and follow-up of malignant neoplasms, and in the detection of occult fractures. Ultrasonography is useful in the characterization of superficial soft-tissue abnormalities, but has not gained high acceptance in searching for internal derangements of the knee. Scintigraphy is competing with MR imaging in the early detection of bone abnormalities and for follow-up. However, it is less expensive and can be employed for the evaluation of multilocular processes. CT has a limited role in the evaluation of complex fractures mainly of the tibial plateau.

- Abstract
In a consecutive series of 166 wrist arthroscopies, a lesion of the meniscus was found in 16 patients. All of them complained of ulnar wrist pain evoked by axial load in extension. 14 patients had previous wrist trauma. The preoperative physical examination showed marked ulnodorsal tenderness on palpation and the examiner could feel crepitation by passive motion in the radial-ulnar direction. The meniscus represents a part of the triangular fibrocartilage complex (TFCC). At this time it is not possible by magnetic resonance imaging (MRI) to differentiate between articular disc and meniscus lesion. In contrast the two structures are clearly identifiable by arthroscopy especially if there is a radial tear through the meniscus or even a complete avulsion from its insertion on the palmar aspect of the triquetrum. The avulsed part of the meniscus can prolapse into the ulnocarpal joint, causing an impingement phenomenon.

- Abstract
The value of MR imaging for the detection of hyaline cartilage lesions using 2-D spin-echo and 3-D gradient-echo imaging was evaluated in an animal experiment in 10 dogs and in a clinical study in 30 patients. MR imaging findings were compared with histopathological and arthroscopy findings, respectively. Using MRI neither grade I nor grade II hyaline cartilage lesions were detectable. In the animal experiments 77% of grade III lesions and all the grade IV lesions were seen. However, in the clinical study only about the half of grade III and IV lesions were detected. 3-D gradient-echo MR imaging was superior to 2-D spin-echo imaging (p < 0.001), while 3-D FLASH and 3-D FISP did not differ significantly in the detection rate (p < 0.34). 3-D gradient-echo MR imaging seems to be the best method for the delineation of high grade cartilage lesions. However, early stages of cartilage degeneration are invisible even with this imaging modality.

- Abstract
The present study proposes a new MRI-specific staging of chondromalacia patellae (CMP) which is based on cartilage thickness decrease and signal intensity behaviour under compression as well as cartilage morphology in the plain image. The investigation was performed in 30 patients with varying knee complaints who underwent arthroscopy after MR imaging. It was demonstrated that three CMP stages can already be differentiated by MRI under compression in arthroscopically healthy cartilage. This proves a marked improvement in the early diagnosis of CMP.

- Abstract
A 49-year-old patient with relapsing polychondritis, who presented in the first instance to an eye department, is described. The patient had episcleritis, papilloedema and posterior scleritis. Both auricles were red, swollen and tender under pressure. The patient responded well to systemic steroid therapy for two weeks. Relapsing polychondritis is a rare connective tissue disorder. Early diagnosis is important, as progressive disease may cause lesions of vital organs (lung, heart).

- Abstract
The aim of this study was to improve the MRI diagnosis of CMP, with special reference to the early stages and accurate staging. For this purpose, the retropatellar cartilage was examined by MRI while compression was carried out, using 21 patients and five normal controls. The compression was applied by means of a specially constructed device. Changes in cartilage thickness and signal intensity were evaluated quantitatively during FLASH and FISP sequences. In all patients the results of arthroscopies were available and in 12 patients, cartilage biopsies had been obtained. CMP stage I could be distinguished from normal cartilage by reduction in cartilage thickness and signal increase from the oedematous cartilage during compression. In CMP stages II/III, abnormal protein deposition of collagen type I could be demonstrated by its compressibility. In stages III and IV, the method does not add any significant additional information.

- Abstract
Magnetic resonance imaging (MRI) provides an excellent soft tissue contrast with high spatial resolution. Using spin echo and fast gradient echo sequences all relevant joint structures such as the hyaline cartilage, the meniscus, the ligaments, the tendons, the capsulae, and their adjacent muscles and their pathology are visualized. Diagnosis of osteonecrosis, meniscal and cruciate ligament lesions, as well as tumors, represents the major current indication for MRI. Due to its high cost MRI should be employed for the diagnosis of joint disease only to clarify equivocal findings of conventional radiographic, nuclear and tomographic methods. Prior clinical examination and laboratory tests are mandatory. As a component of a stepwise diagnostic approach, MRI often provides reliable differential diagnostic information.

In the course of a review of the literature the definition, etiology, diagnosis and treatment of the disease entities chondropathy and patellar chondromalacia are compared. Without exception, the descriptions found are inconsistent and inaccurate. A new classification--chondromalacia, patellar and peripatellar syndrome--is proposed. Possible causes of these diseases in the subchrondral vascular system are mentioned explicitly ("patellar migraine", "patellar claudication").

- Abstract
In a retrospective study of 47 cases of chondromalacia proved by operation, a correct diagnosis had been made by arthrography in three cases. In 44 patients a false negative finding had been obtained. A prospective study was carried out comparing single and double contrast arthrography as well as double contrast arthrotomography and scintigraphy in ten patients with typical chondropathia. It was confirmed by arthroscopy in nine cases. Only two patients with severe chondromalacia showed abnormal findings by arthrography or scintigraphy. Our investigation has led to the conclusion that arthrography is not a suitable method for demonstrating idiopathic chondropathia of the patella.

- Abstract
Observations of nerve root lesions in spontaneous peripatellar pain led to new aspects concerning the etiology of periarticular pain and chondromalacia patellae. We regard the spontaneous peripatellar pain as an enthesiopathia resulting from an innervation disorder. We believe that also chondromalacia can be caused by nerve root lesions. As a consequence, a change in conservative and operative management is necessary. The aim is a balanced gliding and rotational stability of the patella. This means a muscular compensation of the weakened muscle part and stabilisation of the lumbar and hip region. Surgical techniques should only be applied to normalize the gliding of the patella. There is no indication for ventralisation of tuberositas tibiae.
