ABSTRACT
Fungal infections have only rarely been reported to occur in patients having undergone total knee arthroplasty. This case report documents the first known case of Aspergillus fumigatus as the offending organism. Its initial presentation as a popliteal cyst further reinforces the known association of popliteal cysts and intra-articular knee pathology.

The incidence of heterotopic ossification after total hip replacement using the direct lateral approach is compared to the incidence using the transtrochanteric approach. All the initial ectopic ossification occurred by six months following the implant with noncemented fixation. The direct lateral approach adds slightly to the incidence of ectopic ossification as compared to the transtrochanteric approach. Heterotopic ossification of minimal grade did not interfere with any of the planar motions of the hip, whereas severe ectopic ossification disabled the hip in several planes of motion and restricted it significantly in the others. The more severe form of ectopic bone was more common after the transtrochanteric approach to the hip, while the lighter form developed more often following the direct lateral approach.

A 45-year-old man was treated for peroneal nerve compression secondary to an osteophyte in the posterior compartment of the knee. Surgical excision led to complete resolution of symptoms.
ABSTRACT
Intra-articular tumors of the knee joint causing intermittent locking are extremely rare. A 39-year-old woman with the complaint of joint locking had a pedunculated intra-articular mass and nodular synovitis.

Hypopigmentation at a site of application of a tourniquet has not to our knowledge been reported in the literature. We are reporting such a case. We have conjectured that this hypopigmentation may be due to temporary anoxia suffered by melanocytes.
