Surgery resection of chondroma in Orthopedic Clinic Freiburg

About the department

The Department of Adult and Pediatric Orthopedics, Foot Surgery and Hand Surgery at the Orthopedic Clinic Freiburg provides the full range of medical services in the areas of its specialization. The focus of the team of doctors at the medical facility is on patients with pathologies of large joints, including the knee, hip, shoulder, elbow, ankle, and wrist joints. The department's special offer is autologous cartilage transplantation, which is performed by a very limited number of medical centers in Europe. This innovative surgical technique allows doctors to cure knee, hip, ankle, and shoulder arthrosis. With more than 700 interventions of this kind annually, the department's specialists are deservedly proud of their successful results and professional skills in this field. The department also treats foot and hand diseases, including hallux valgus, hallux rigidus, flat feet, hollow feet, Morton's neuroma, rhizarthrosis, Dupuytren's contracture, trigger fingers, and other pathologies. Surgical interventions for musculoskeletal diseases in adults and children are performed in two high-tech operating rooms that were opened in May 2020. In most cases, the department's doctors manage to perform low-traumatic operations, after which patients recover quickly and leave the hospital as soon as possible. The department performs more than 2,500 interventions annually. The department's team strives to provide patients with top-class medical services in a pleasant and friendly environment. The Head Physician of the department is Prof. Dr. med. Sven Ostermeier.

The priority focus of the department's doctors is autologous cartilage transplantation (the procedure is also called autologous chondrocyte transplantation). The essence of this therapeutic technique is as follows: doctors take a small amount of cartilage tissue, grow the necessary amount of this biological material in the laboratory, and then inject it back into the patient's joint using minimally invasive techniques. The final treatment outcomes can be assessed after 3 months, and after a year, the transplanted cartilage is no different from the patient's own cartilage tissue. The department is a pioneer in the field of autologous cartilage transplantation, so it has tremendous experience in the use of this technique for treating knee, hip, shoulder, and ankle arthrosis. Autologous chondrocyte transplantation is most often indicated for patients with knee arthrosis (gonarthrosis). The treatment technique is a real breakthrough in modern orthopedics since it allows patients to get rid of arthrosis, which causes mobility restrictions and severe pain, without any joint replacement surgery (a surgical procedure to replace the joint with a prosthesis). Autologous cartilage transplantation is not suitable for all patients since it does not give the desired result in the advanced stages of arthrosis. As a rule, ideal candidates for this treatment are patients between the ages of 15 and 55 with intact or partially preserved menisci, without cruciate ligament injuries of the knee, without axial joint disorders, and with a minimum of 2.5 cm2 of cartilage preserved. However, the decision to perform autologous chondrocyte transplantation is made individually, based on the patient's clinical data and general health condition. The department's orthopedists have successfully performed the procedure more than once on patients under the age of 65 who lead an active lifestyle. The key advantages of the method are the restoration of mobility and the elimination of pain, thanks to which patients return to an active lifestyle. In addition, long-term clinical follow-up monitoring of patients after autologous cartilage transplantation confirms the absence of any complications or health problems after surgical treatment.

The department also treats other knee joint diseases, such as meniscus tears, knee ligament tears, patellar dislocation and fracture, dissecting knee osteochondritis, etc. A patellar fracture treatment can be either conservative or surgical, but surgery is usually required. Depending on the severity of the injury, special screws or implants can be placed during the operation, and, in the most complex cases, fragments or even the entire patella have to be removed. A surgical intervention is always followed by a course of rehabilitation aimed at the maximum restoration of the patient's mobility. The department's patients with torn ligaments are also offered conservative and surgical treatment methods. In this case, conservative therapy is most often carried out as a preparation for surgery. As for surgical treatment options, the department's orthopedists successfully perform cruciate ligament plastic surgery, cruciate ligament replacement surgery using the hamstring as an autologous graft, or cruciate ligament suturing. Knee joint operations are almost always performed using low-traumatic surgical techniques that allow patients to recover as soon as possible and return to their normal lives. In addition, when performing knee replacement surgery and other interventions, doctors use the innovative NAVIO navigation system manufactured by the American company Smith & Nephew, which was installed in the operating room in 2020.

The department's specialists treat the full range of hip joint diseases, including arthrosis, intra-articular loose bodies in the hip joint, coxitis, hip impingement, avascular necrosis of the femoral head, and femoral neck fractures. Doctors also treat young patients with hip joint pathologies, the most common of which are Perthes disease and slipped capital femoral epiphysis. The majority of hip joint interventions are arthroscopic manipulations and joint replacement surgery. In addition, the department's specialists successfully deal with articular cartilage repair (for example, in the case of minor cartilage lesions caused by injuries) using the advanced technique of autologous cartilage transplantation or microfracturing. In most cases, hip surgery is performed through a minimally invasive approach using miniature skin incisions or punctures. Patients thus do not experience a severe pain syndrome, blood loss is significantly reduced, and there are practically no surgical risks.

Foot surgery is also an important field of the department's clinical practice. In this area, special attention is paid to the surgical repair of foot deformities, such as hallux valgus, hallux rigidus, hollow foot, clubfoot, flat feet, and hammer and claw toe deformities. The department's doctors also successfully repair foot deformities in children, including flat feet and tarsal coalitions. The department's orthopedists have excellent professional skills in the repair of hallux rigidus (arthrosis of the first metatarsophalangeal joint of the foot). Depending on the severity of the deformity and the patient's general health condition, such surgical techniques as arthrodesis, cheilectomy, hemiprosthesis placement, and CARTIVA partial replacement may be used. For hallux valgus (the formation of a bone "bump" in the area of the big toe) repair, a chevron osteotomy is most often performed. Of particular interest is the treatment of flat feet in children. Conservative therapy is preferred whenever possible, which includes physical exercises (for example, tiptoe standing, circular dynamic exercises for the legs), body weight normalization, wearing orthopedic insoles, etc. In severe cases of flat feet, a surgical intervention may be performed. The department's specialists offer minimally invasive implant surgery, arthrolysis, or the Evans osteotomy for young patients. The optimal type of surgical intervention is determined on an individual basis.

In the field of hand surgery, the department provides patients with effective treatment for finger arthrosis, rhizarthrosis, carpal tunnel syndrome, trigger fingers, and Dupuytren's contracture. In many cases, hand diseases can be treated with conservative methods, but surgery may sometimes be required. Surgical procedures on the hand are performed using microsurgical techniques, which is a great advantage for patients.
