Randomized Controlled Trial
[Postoperative analgesia after total knee arthroplasty: Continuous intra-articular catheter vs. continuous femoral nerve block].
Postoperative pain management after total knee arthroplasty (TKA) remains a great challenge even today. In the context of new fast-track concepts, the importance of multimodal therapies for the effective treatment of pain and the reduction of side effects, as well as for the rapid ambulation of patients is increasing. Therefore, new continuous intra-articular catheter-systems (IAC) are under investigation. ⋯ The perioperative treatment with an IAC system is an easy technique, which ensures a markedly faster ambulation following TKA compared to the treatment with continuous FNB. Hence, its usage, especially in fast-track concepts can be recommended. In this study, a comparison of pain intensity, the additional requirement of opioids and early range of motion (ROM) offers no benefits compared to FNB. Due to time savings cost reduction can be achieved.

Transfemoral amputations with more proximal amputation levels have the problem of secondary development into flexion and abduction contractures. This is induced by muscle imbalance, especially the loss of adductor muscle insertions when abductor muscle insertions are preserved. This causes considerable problems when fitting prosthetics. Myodesis with insertion of the distally detached adductor magnus muscle to the lateral femoral cortex, introduced here, results in a stronger stump with good muscle balance, and prosthetics fitting is significantly improved.

Increasing rates of periprosthetic joint infections (PJI) will present orthopedic surgeons and the health care system with challenges in the next few years. New concepts in diagnostic and surgical pathways allow specialized centers to offer differentiated therapy of PJI. ⋯ PJI represents a significant challenge for the orthopedic surgeon. Evidence-based and standardized clinical pathways are necessary for accurate and rapid diagnosis as well as patient-specific treatment concepts.
