Case ReportsSeptic arthritis of the knee associated with calf abscess.
Septic arthritis associated with extra-articular abscess is rare. We report on 2 non-rheumatic patients with septic arthritis of the knee associated with calf abscess. Magnetic resonance imaging showed a distinct leakage pathway from the knee joint in each patient. ⋯ Another was a pathologic popliteus hiatus (posterolateral). These patients underwent open drainage of the calf abscess via a small incision, followed by arthroscopic debridement of the knee. Careful palpation of the lower leg, followed by magnetic resonance imaging and needle aspiration, is important to exclude a possible extra-articular abscess regardless of the presence of a popliteal cyst.

Case ReportsMating of a PROSTALAC spacer with an intramedullary nail for reconstruction of an infected interprosthetic femoral shaft fracture: a case report.
Reconstruction for concurrent infection of an ipsilateral total hip arthroplasty (THA) and total knee arthroplasty (TKA) is a challenge. We report a 2-stage reconstruction of a THA for chronic infection of both the THA and TKA with severe femoral bone loss secondary to interprosthetic fractures. The reconstruction involved using a custom-made, temporary, antibiotic-impregnated PROSTALAC spacer mated with an intramedullary nail. ⋯ A customised abduction brace was fitted, and partial weight bearing was allowed. Sufficient leg length, soft-tissue tension, and range of hip motion were restored, and a total femur and constrained liner was re-implanted 4 months later. Mating of an intramedullary nail with a PROSTALAC spacer is a viable reconstructive option.
