Bipolar Fresh Osteochondral Allograft Transplantation of the Tibiotalar Joint: A Concise Mid-Term Follow-up of a Previous Report★.

Despite advances in managing degenerative arthritis of the ankle joint, there are few optimal treatment options for young patients with symptomatic, end-stage degenerative disease. Popular surgical options consist of traditional arthrodesis and, more recently, arthroplasty. Additional techniques, including arthroscopic debridement and joint distraction, have gained little traction.

Evaluation of polyethylene glycol based hydrogel for tissue sealing after laparoscopic partial nephrectomy in a porcine model.

Purpose: Polyethylene glycol (PEG) based hydrogel is available as a tissue sealant and hemostatic aid. We determined the long-term safety and efficacy of its use as a tissue sealant for laparoscopic partial nephrectomy in a porcine model.

Materials And Methods: A total of 16 swine were cycled to 1 control group and 3 treatment groups, which underwent laparoscopic partial nephrectomy with hemostasis achieved only with application of a biodegradable PEG based hydrogel.
