Pyoderma gangrenosum following trauma of the knee: a case of pathergy and review of orthopaedic cases.

Pyoderma gangrenosum (PG) is a rare noninfectious neutrophilic dermatosis. Its course can be mild or malignant, chronic or relapsing with remarkable morbidity. We describe a case of PG, which presented with severe wound breakdown following a closed tibial plateau fracture of the left knee.

Complete slippage of capital femoral epiphysis: total hip arthroplasty with custom-made stem.

Slipped capital femoral epiphysis occurs in adolescents, most often shortly after the onset of puberty. In patients suffering form renal osteodystrophy, the incidence is higher and the condition usually occurs at a younger age. Metabolic changes induce weakening of the bone, which makes the hip joint vulnerable.

Ochronosis, arthroscopy of a black knee: a case report and review of the literature.

Ochronotic arthropathy is a rare condition found in patients with alkaptonuria. Due to the accumulation of homogentisic acid, cartilages get a dark discoloration and become brittle and more vulnerable to mechanical stress (Centinus et al. Rheumatol Int 3:127-131, 2004; Hamdi et al.

Arthroscopic meniscus repair in the ACL-deficient knee.

Between 1985 and 1995, 45 patients underwent closed meniscus repair. There were 30 men and 15 women with a mean age of 32.5 years.

Magnetic reasonance imaging of the surgically repaired meniscus: a 13-year follow-up study of 13 knees.

Background: This study was initiated to evaluate the long-term outcome of meniscal sutures and to correlate clinical findings with MRI findings. We were interested to see if a clinically healed meniscus also showed as such on MRI and if degenerative changes were present

Patients And Methods: We studied prospectively 13 patients (7 men) aged between 29 and 50 years, who had undergone closed meniscus repair between 1985 and 1988 using an inside-out technique, clinically and with MRI, with a mean follow-up time of 13 years.

Results: Meniscal suture gave good clinical long-term results: all patients got a Hospital for Special Surgery score of more than 75%.
