Comparative StudyExpectation, satisfaction and clinical outcome of patients after total knee arthroplasty.
There is a well-known difference between patients expectation, satisfaction and the measured clinical outcome in total knee arthroplasty (TKA). It has been hypothesized that higher expectation prior to surgery and higher satisfaction will show better clinical outcome according to well-established scoring systems, frequently used for assessment after TKA. ⋯ This study has shown that patient satisfaction correlates well with the clinical outcome according to the KSS, WOMAC and SF-36. The indication for TKA should consider the general health, emotional role and knee function of the patients as well in order to predict patient's outcome.

Comparative StudyTreatment of periprosthetic femoral fractures of the knee.
We report a continuous series of periprosthetic femoral fractures after knee arthroplasty treated with a locking plate. We hypothesize that minimally invasive surgery and immediate weight-bearing improve functional recovery. ⋯ Osteosynthesis with a minimally invasive bridge-plating technique is effective in the treatment of periprosthetic, distal femoral fractures without component loosening. Immediate full weight-bearing is possible if certain rules are respected. The surgical management presented herein is beneficial for these challenging fractures, and it may help reduce the complication rate and improve functional outcome.

Comparative StudyThe effect of femoral component rotation on the kinematics of the tibiofemoral and patellofemoral joints after total knee arthroplasty.
Complications after total knee arthroplasty (TKA) often involve the patellofemoral joint, and problems with patellar maltracking or lateral instability have sometimes been addressed by external rotation of the femoral component. This work sought to measure the changes of knee kinematics caused by TKA and then to optimise the restoration of both the patellofemoral and tibiofemoral joint kinematics, by variation of femoral component internal-external rotation. ⋯ It was concluded that femoral rotation alone could not restore all aspects of both patellar and tibial kinematics to normal with this specific implant. The clinical relevance of this is that it appears to be inadvisable to reposition the femoral component, in an attempt to improve patellar tracking, if that repositioning may then cause abnormal tibiofemoral kinematics. Further, the pattern of patellar tracking, with the type of TKA used in this study, could not be adjusted to normal by femoral component rotation.

Comparative StudyAnterior knee pain after total knee arthroplasty: does it correlate with patellar blood flow?
Total knee arthroplasty (TKA) disturbs patellar blood flow, an unintended accompaniment to TKA that may be a cause of postoperative anterior knee pain. We examine whether disrupted patellar blood flow correlates with anterior knee pain following TKA. ⋯ Medial arthrotomy had no direct significant effect on patellar blood flow, and the diminished blood flow did not correlate with postoperative anterior knee pain. However, a significant correlation was revealed between patellar blood flow and the degree of flexion: in almost a quarter of patients, blood flow dropped to zero at flexions of 100° and above.

Comparative StudyPrevalence of joint-related pain in the extremities and spine in five groups of top athletes.
Joint-related pain conditions from the spine and extremities are common among top athletes. The frequency of back pain has, however, been studied in more detail, and the frequency of low-back pain in top athletes in different high-load sports has been reported to be as high as 85%. Sport-related pain from different joints in the extremities is, however, infrequently reported on in the literature. ⋯ There was no statistically significant difference in prevalence of pain in the neck, spine and joints between top athletes in different sports or between athletes and non-athletes. However, pain in one spinal region was correlated to reported pain in other regions of the spine. Moreover, pain in the spine was also correlated to pain in the shoulders, hips and knees.
