ABSTRACT
Ever since the first Total Knee Arthroplasty was made to our present times, a point that still generates controversy is, if the accomplishment of patellar resurfacing will take to a higher global rate of complications. It was the final objective of our work to analyze clinically and radiologically, in addition to satisfaction degree and quality of life surveys, the patellar resurfacing in a sample of total knee arthroplasty made in our center. We can conclude that in our experience, the patellar resurfacing has a low incidence of complications, which do not affect in a significant way the quality of life of the patients carrying on a total knee arthroplasty, which justifies this procedure absolutely.
Desde que se realizan las Artroplastías Totales de Rodilla hasta la fecha, un punto que genera controversia, es, si la realización de un componente protésico patelar llevará a una mayor tasa global de complicaciones. Es por eso que el objetivo de nuestro trabajo fue analizar clínica y radiológicamente, además de encuestas del grado de satisfacción, el componente de recubrimiento patelar en una muestra de las artroplastías totales de rodilla realizadas en nuestro centro. Se concluye que en nuestra experiencia, el uso de recubrimiento patelar tiene una baja incidencia de complicaciones, las cuales no afectan de manera significativa la calidad de vida de los pacientes con artroplastía total de rodilla, lo que justifica plenamente su utilización.

Background: Bone marrow edema syndrome (BMES) is a rare clinical condition. Its etiology is unknown and it can be seen in different locations. In the case of the hip, avascular necrosis is the main differential diagnosis. Aim: To present our experience of BMES of the hip and a review of the literature. Patients and methods: Retrospective analysis of clinical records of patients with hip pain that met clinical, radiological, and magnetic resonance imaging criteria for BMES. Clinical outcome and clinical and radiological follow up are presented. Results: Two men and two women (one of them pregnant) aged 42, 48, 36 and 26 years old, fulfilled criteria. Treatment included limited weight bearing, non steroidal antiinflammatory drugs, intranasal calcitonin and physical therapy. Complete remission of symptoms was observed within five to seven months. At an average follow up of 36 months, all patients presented complete function of the hip, returning to their previous activity levels, with no new episodes of BMES. Conclusions: It is important to be aware of this condition as part of the differential diagnosis of hip pain to avoid aggressive and unnecessary diagnostic and therapeutic procedures (Rev Méd Chile 2004; 132: 947-54).

Background: Approximately 90 percent of patients with rheumatoid arthritis (RA) will have one or both knees involved during the course of the disease. Total knee arthroplasty (TKA) allows restoring function and relieving pain satisfactorily, but these patients perform in a different way than those with primary knee osteoarthritis. Aim: To evaluate the clinical and radiographic results of TKA in patients with RA. Patients and methods: We analyzed retrospectively the data of 25 posterior stabilized total knee prostheses in 19 patients, available to an average follow-up of 6 years. The scores of Hospital for Special Surgery and of the Knee Society were used for clinical assessment. Results: The mean Hospital for Special Surgery score increased from 44 points (range 27-58) preoperatively to 80 points (range 58-91) at the final follow-up examination. Two prostheses required revision and removal of the implants because of deep infection, and two had clinical failure as defined by the Knee Society score. There were no cases of implant loosening. Discussion: Even though it is not free of complications, TKA is a good choice in patients with RA in the medium term follow up, with 80 percent of excellent and good results in our series (Rev MÚd Chile 2004; 132: 337-45).

La condromatosis sonovial es un proceso beningo infrecuente que afecta las articulacione y otras estructuras que contienen tejido sinovial. Se presenta el caso de una mujer de 46 años con condromatosis sinovial sintomática de cadera derecha, en etapa inicial, localizada en la fosa acetabular. El tratamiento fue la resección abierta de la lesión mediante luxación quirúrgica de la cadera. No hubo complicaciones intra o postoperatorias y la osteotomía consolidó adecuadamente. Al último seguimiento, la paciente no tiene dolor y realiza una vida normal.
