We report on two patients with neuropathic knee pain following lesions of the infrapatellar branch of the femoral nerve due to knee joint replacement. In one patient, the neuropathic pain syndrome was complicated by the development of complex regional pain syndrome (CPRS II, causalgia). ⋯ This nerve is a branch of the femoral nerve medial to the fascia lata and is responsible for the skin sensation of the anterior and medial part of the knee. Clinical features, anatomy, diagnostic methods and therapeutic options are reviewed.

Randomized Controlled Trial Comparative Study
[Comparison of the peripheral and central effects of opiates after iliac crest transplants. Reconstruction of severely atrophied maxilla].
Severe pain is one of the main problems after harvesting iliac crest transplants. In this randomized double-blind study differences in the peripheral and central effects of opiates for pain treatment in the iliac crest region after augmentation of the severely resorbed maxilla were examined. ⋯ The effect of centrally given opiates is more effective in the early postoperative period. In the early rehabilitation period the effect of intraoperatively local peripherally placed opiates is superior to intraoperatively centrally administered opiates.

Randomized Controlled Trial Comparative Study
[Pain therapy using stimulating catheters after total knee arthroplasty].
Epidural analgesia and continuous femoral nerve blocks are often used for pain therapy after total knee arthroplasty. The additional use of a continuous sciatic nerve block is controversially discussed. To avoid the problem of inaccurate placement a stimulating catheter may be useful. The aim of this study was to compare the effectiveness of a continuous femoral nerve block with an additional continuous sciatic nerve block for improved functional recovery and pain relief. ⋯ Using stimulating catheters for pain therapy the three methods are largely comparable and other parameters should be used for individual selection.

Comparative Study
[Intensity of limb pain and fatigue in fibromyalgia syndrome, depressive disorders and chronic back pain. A criterion for differentiation].
A symptom-based diagnosis of fibromyalgia syndrome (FMS) without tender point examination is needed for primary care. We tested if a symptom-based diagnosis of FMS can be founded on the intensity of the symptoms musculoskeletal pain and fatigue. ⋯ High levels of the intensity of chronic widespread musculoskeletal pain and chronic fatigue may form the basis of a symptom-based diagnosis of FMS.

Comparative Study
[Correlation between quantitative sensory testing and questionnaires on neuropathic pain for chronic ischemic pain in peripheral arterial disease].
A neuropathic component to chronic ischemic pain in peripheral arterial disease (PAD) has recently been shown using quantitative sensory testing (QST) and pain questionnaires. The aim of this study was to examine correlations between QST and pain questionnaires in patients with chronic ischemic pain. ⋯ The results suggest that there might be correlations between psychophysical tests (QST) and pain questionnaires. Subjective perceptions of pain might be represented by a certain pattern in the QST. These connections could contribute to further clarify the pathophysiologic mechanisms leading to the perception of pain.
