Several factors influence clinical outcome after autologous chondrocyte implantation (ACI) for the treatment of cartilage defects of the knee joint. ⋯ Cell quality seems to be one of many factors that influences clinical outcome after ACI in patients with cartilage defects of the knee joint. It constitutes one aspect among various others affecting clinical outcome.

Clinical Trial
Effectiveness of the women's lacrosse protective eyewear mandate in the reduction of eye injuries.
In an effort to minimize the risk of catastrophic eye injury, US Lacrosse initiated mandatory use of protective eyewear in women's lacrosse in the 2004-2005 season. ⋯ The use of protective eyewear in women's lacrosse was associated with a reduction in the number of eye injuries. The number of head/face injuries decreased in this study group after introduction of protective eyewear, and there was no change in overall injury rates. The reason for the increase in concussion rate cannot be determined conclusively based on this study, but the authors speculate that this increase resulted largely from increased recognition and diagnosis because overall injury rates do not indicate rougher play with introduction of protective equipment.

Comparative Study
Jones fracture fixation: a biomechanical comparison of partially threaded screws versus tapered variable pitch screws.
Stabilization of fifth metatarsal Jones fractures with intramedullary screw fixation is the most common method for surgical fixation when operative treatment is indicated. Conventional partially threaded screws of various diameters are routinely used for Jones fracture fixation. Recently, the use of tapered variable pitch screws has become popular, but information regarding their performance in Jones fracture fixation is limited. No previous studies have compared conventional and tapered variable pitch screws in Jones fracture fixation under physiologic cyclic loading conditions. ⋯ While the use of tapered variable pitch screws is a potential alternative for fixation of fifth metatarsal Jones fractures, conventional partially threaded screws may provide better biomechanical stability, the effect of which on fracture healing is unknown.

Clinical Trial
Ultrasound-guided sclerosis of neovessels in patellar tendinopathy: a prospective study of 101 patients.
A randomized controlled study has shown promising clinical results after treatment with sclerosing injections in a group of patients with patellar tendinopathy, but no study has investigated medium- or long-term outcome in a large and unselected group of patients. ⋯ Sclerosing treatment with polidocanol resulted in a moderate improvement in knee function and reduced pain in a heterogeneous group of patients with patellar tendinopathy. Nevertheless, few of the patients were cured, and the majority still had reduced function and substantial pain after 24 months of follow-up.

There is a lack of prospective studies comparing the long-term outcome of endoscopic anterior cruciate ligament (ACL) reconstruction with either a patellar tendon or hamstring tendon autograft. ⋯ Anterior cruciate ligament reconstruction using ipsilateral autograft continues to show excellent results in terms of patient satisfaction, symptoms, function, activity level, and stability. The use of HT autograft does, however, show better outcomes than the PT autograft in all of these outcome measures. Additionally, at 15 years, the HT graft-reconstructed ACLs have shown a lower rate of radiological osteoarthritis.
