Current treatments are targeted at reducing symptoms of the inflammatory reaction that occurs after destruction of essential joint cartilage. However, these treatments do not prevent significant pain and activity restriction. We reviewed the literature to address claims that fish oil supplementation can prevent or decrease severity of OA. Our extensive search of databases covered all relevant terms related to omega-3-containing supplements and their effects on OA. We hypothesized there would be insufficient clinical studies to justify recommending supplementation to patients.Laboratory studies have shown that eicosapentaenoic acid and docosahexaenoic acid reduce proinflammatory mediators and increase joint lubrication in vitro. In addition, canine trials have shown clinically significant reductions in various symptom parameters. Result...

We report a case of failure of the stem-condyle junction of a modular femoral component of a revision total knee implant, despite appearing well fixed on preoperative radiographs. Intraoperatively, there was dissociation of the condylar component from the well-fixed, cemented stem, creating motion at the stem-condyle junction. To our knowledge, this failure mode has not been reported in the literature.

This patient population is generally intolerant of intra-articular screw fixation and can develop significant post-traumatic arthritis with potentially career ending complications. Flexible fixation with suture-button devices provides potential restoration of physiologic motion at the joint, with appropriate support for healing that may facilitate return to en pointe activities for dancers. We hypothesized that the suture-button device would restore motion at the Lisfranc joint and allow for return to activities in this particular population without the limitations and complications of rigid fixation. We operated on seven dancers and high-level athletes with diagnosed Lisfranc injuries by installing a suture-button device. All patients had failed conservative management after late presentation. They were allowed to return to sport in 6 months, preoperative and postoperative American Orthopaedic Foot and Ankle Score (AOFAS) foot scores were obtained, and patients were followed for a minimum of 15 months. All seven returned to full activities in 6 months, with radiographic evidence of fixation and no complications to date. AOFAS foot scores improved from an average of 65 preoperatively to an average of 97 postoperatively at latest follow-up. It is concluded that flexible fixation with suture-button type device represents a viable alternative to screw fixation or fusion that may allow dancers and athletes to return to previous levels of activity after Lisfranc injury. This case series represents to our knowledge the first application of this device to a unique population that requires flexibility at the Lisfranc joint for performance.
