Randomized Controlled Trial[Postoperative autologous transfusion from blood drainage after total hip joint arthroplasty--how much value is really there?].
Are autologous blood transfusions sufficient or do we need the transfusion of unwashed or washed wound drainage blood in total hip arthroplasty? ⋯ We do not recommend the transfusion of wound drainage.

Randomized Controlled Trial Clinical Trial[Influence of local anesthesia and energy level on the clinical outcome of extracorporeal shock wave-treatment of chronic plantar fasciitis].
The efficacy of low energy extracorporeal shock wave treatment (ESWT) for chronic plantar fasciitis is discussed controversially. It is unclear whether the simultaneous application of local anesthesia (LA) interferes with clinical outcome. ⋯ At 6 weeks success rates after low-energy ESWT with local anesthesia were significantly lower than after identical low-energy ESWT without local anesthesia. Higher energy levels could not balance the disadvantage of this effect. LA significantly influenced the clinical results after low energy ESWT in a negative way. Blinding patients by LA in ESWT studies must therefore be considered a systematic error in study design.

Randomized Controlled Trial Comparative Study Clinical Trial[First results of anterior versus posterior instrumentation-fusion in the treatment of spondylodiscitis].
The present study on spondylodiscitis patients was carried out to compare prospectively and randomized the results of clinical and radiological outcomes of anterior versus posterior instrumentation after debridement and grafting. We aimed to make a recommendation concerning the optimum treatment of spondylodiscitis. ⋯ We found advantages with anterior instrumentation in comparison to posterior stabilization in patients with spondylodiscitis. Advantages of ventral stabilization cause early mobilization postoperatively without any increase in complication rates. Except for operation time and intraoperative blood loss, no statistical difference were was seen. Important is the individual indication for each method depending on anatomical and clinical signs. Ventral instrumentation should be restricted to cases with sufficient bone stock.

Randomized Controlled Trial Comparative Study Clinical Trial[Cemented versus cementless revision femoral stems using morselized allograft--a prospective, randomized study with 5 years follow-up].
There are only few studies on hip revision using the impaction grafting technique. Furthermore, data on cementless femoral stems as compared to cemented and polished femoral stems are lacking. We wanted to determine whether cementless femoral stems were equally good in preserving bone mineral density around the femoral stem and in functional outcome. ⋯ Cemented technique in hip revisions using morselized bone allograft is as good as uncemented technique in preserving BMD measured by the DEXA method and restoring function in a 5 years follow-up.

Randomized Controlled Trial Clinical Trial[Patella resurfacing in patients without substantial retropatellar knee pain symptoms?].
The aim is of this prospective randomised study was to investigate the necessity of resurfacing the patella in combination with total knee arthroplasty in patients without or mild anterior knee pain before undergoing total knee replacement. ⋯ The presented study demonstrated after one year follow-up a better functional result, a higher degree of contentment and fewer complications after total knee replacement with patella resurfacing in patients without or mild preoperative anterior knee pain.
