Osteochondral Allograft Transplantation Surgery for Osteochondral Lesions of the Talus in Athletes.

Osteochondral lesions of the talus (OLTs) continue to be a challenge for the treating surgeon, especially when lesions are refractory to marrow stimulation techniques. The purpose of this study is to evaluate the outcomes of lesions treated with osteochondral allograft transplantation. A review was performed of 30 athletes with 31 OLTs that were refractory to marrow stimulation or predicted to be refractory based on size and location of the lesion. Results were evaluated in terms of occupational outcomes and numeric pain scales. Lesions treated had a mean area of 1.37 (range 0.36 to 3.3) cm2. Overall excellent outcomes were achieved in 11 (35%) ankles. Nineteen (61%) ankles achieved good or excellent occupational outcomes, and 12 (39%) ankles demonstrated poor occupational outcomes and the patients were unable to continue their previous active occupations. Patients were found to have a mean pain scale score of 3 (range 0 to 7) of 10 at a mean of 21 (range 10 to 24) months after operative management. Osteochondral allograft transplantation is an option for the treatment of selected athletes with large OLTs, as well as lesions that are refractory to marrow stimulation techniques. The results of this study may help active young patients and their surgeons to better understand outcomes and options in their shared decision-making process.

Septic arthritis following anterior cruciate ligament reconstruction: a comprehensive review of the literature.

Septic arthritis following anterior cruciate ligament (ACL) reconstruction is an uncommon but potentially serious complication. The incidence of infection is approximately 0.44%. Staphylococcus and streptococcus strains are the most common infectious pathogens. Infection is typically via direct inoculation. Articular cartilage damage is primarily the result of the unregulated host inflammatory response. The timing of presentation is typically <2 months following surgery. Presenting symptoms commonly mirror normal postoperative findings, making diagnosis difficult. Although laboratory inflammatory markers are often elevated, knee arthrocentesis is the gold standard for diagnosis. Treatment involves serial arthroscopic or open irrigation and debridement procedures and antibiotic management. Graft retention is often possible, although fixation implants may require removal or exchange. Successful results have been reported following infection eradication in both graft retention and early revision ACL reconstruction scenarios.
