Extraarticular infection 9 years after anterior cruciate ligament reconstruction. Case report.

Extraarticular infection after anterior cruciate ligament reconstruction (ACLr) is a rare condition with challenging diagnosis because the symptoms are milder and more insidious when compared to septic arthritis. When late (>2 months after surgery), it tends to be associated with osteomyelitis, requiring more extensive surgical debridement and hardware removal. We report a case of extraarticular infection after ACLr, in the acute phase affecting the tibial site and 9 years after index surgery affecting around the femur site.

Early tibial component loosening of medial UKA after severe medial plateau SONK-report of three cases.

Spontaneous osteonecrosis or subchondral bone insufficiency fracture of the knee is a frequent injury in elderly female patients. The medial femoral condyle followed by the medial plateau is the most prevalent sites. When its evolution after conservative treatment is not favorable, medial unicompartimental arthroplasty is a surgical option with good results.

Leucocyte-poor-platelet-rich plasma intra-operative injection in chondral knee injuries improve patients outcomes. A prospective randomized trial.

Purpose: Evaluate the effects of intra-operative leucocyte-poor-platelet-rich plasma (PRP) (type P3-Bβ with endogenous activation) injection in International Cartilage Repair Society (ICRS) grade III knee chondral injuries treated by chondroplasties, to increase and ameliorate the repair tissue.

Methods: Patients were divided into two groups. Group A (control) consisted of 31 patients and Group B (PRP) 33 patients, totaling 64 patients analyzed.
