The clinical and radiological results of revision of low friction arthroplasty in the elderly.

We assessed 130 patients (138 hips) who were more than 70 years old at the time of revision arthroplasty and had a minimum follow-up of 4 years. The average follow-up was for 7 years 3 months. The clinical results were excellent or satisfactory in 95.6% of the cases. Systemic complications developed postoperatively in 47 patients (34.1%). Radiographically, 95.6% had a well-fixed, stable stem while 91.3% had a stable socket. Seven hips (5.1%) required re-revision. Analysis revealed a 96.5% survival of the arthroplasty at 8 years.

One-stage revision of total hip arthroplasty for deep infection. Long-term followup.

One hundred eighty-three total hip arthroplasties were revised for deep infection in a 1-stage procedure using antibiotic containing acrylic cement and systemic perioperative antibiotics. At an average followup of 7 years 9 months, 154 (84.2%) patients were free of infection. The remaining 29 (15.8%) patients had evidence of persistent infection. The quality of pain relief immediately after a revision for deep infection often is a good predictor of success.

Multiple revision for failed Charnley low-friction arthroplasty.

We reviewed 54 patients at a mean follow-up of 4 years 4 months after rerevisions for failure of Charnley low-friction arthroplasty. Rerevision for aseptic loosening in 26 hips was satisfactory; there were no clinical failures and at the latest radiological assessment only one stem and three sockets showed signs of loosening. By contrast, nine of 20 multiple revisions for recurrent dislocation failed, as did five of eight multiple revisions for deep infection. There was radiological evidence of loosening in one stem and nine sockets in the former group and in three stems and five sockets in the latter.

Cemented revision for aseptic acetabular loosening. A review of 387 hips.

We reviewed the records and radiographs of 387 cemented revisions of aseptic loose sockets after total hip replacement at a mean follow-up of 5.5 years. The clinical results were satisfactory, but at the last radiological assessment 38 sockets (9.8%) had a continuous zone of demarcation greater than 1 mm thick and another 35 (9%) showed migration. Poor acetabular bone stock had a profound influence on the outcome of revision surgery, but the results of cemented revision were comparable to those reported for cementless revision at similar mean follow-up.

Cemented Charnley revision arthroplasty for severe femoral osteolysis.

We reviewed prospectively cemented stem revision in 106 patients with severe femoral endosteal bone lysis without infection. Bone grafts were not used in any of the patients. The minimum follow-up was three years (mean 6 years 4 months). At the last review 76.4% of the patients were free of pain and 17.9% had only mild or occasional discomfort; radiographs showed well-fixed stable stems in 101 (95.3%). An intramedullary cement plug was used at revision to improve stability in 97.7%. There was new endosteal osteolysis after revision in 17 patients; only two had severe changes. Seven hips (6.6%) required a second revision; only four of these (3.8%) were for stem loosening. Survivorship of the revised stem, using radiological evidence of stem loosening as the end point, was 95.8% at seven years. The results of stem revision arthroplasty using cement in the presence of massive endosteal cavitation are satisfactory.

Revision for aseptic stem loosening using the cemented Charnley prosthesis. A review of 351 hips.

We reviewed 351 cemented revisions of femoral stems performed for aseptic loosening. At a mean of six years after the revision operation 72.1% of the patients were pain-free and 21.4% had only mild or occasional discomfort. The latest radiographs showed definite stem loosening in 10 (2.8%) and 20 hips (5.7%) had required rerevision, only nine (2.6%) of which were for mechanical failure of the stem. Survivorship analysis, taking the end point as rerevision of the stem, gave 97.0% survival at eight years and 91.6% at 11 years. Excellent results both clinically and radiologically can be achieved by cemented revision of the femoral stem for aseptic loosening.

Bulk autograft for a deficient acetabulum in Charnley low-friction arthroplasty. A 2-9-year follow-up study.

The authors assessed 40 hips in 36 patients where a bulk femoral head autograft was used to supplement deficient acetabulum while performing Charnley low-friction arthroplasty. The majority of the hips were congenitally dysplastic or dislocated with secondary arthritis. The average age at surgery was 47.5 years and the average follow-up period was 4 years. The graft provided a cover between 10 and 42% (mean, 23%) of the socket hemisphere. Union of the graft was evident on the radiograph in 35 hips. There was no graft resorption in 28 hips. Mild graft resorption was seen in 11 cases, and moderate graft resorption was seen in 1 case. In 24 cases, there was no demarcation at the bone-cement interface of the socket. Asymptomatic demarcation of 1 mm thickness or less was seen in 16 hips, of which only 2 showed demarcation at the cement-graft interface. All 40 cases were clinically asymptomatic and successful thus far, with the mean d'Aubigne and Postel score improving from 3.1, 2.8, and 2.9 before surgery to 5.9, 5.4, and 4.9 after surgery for pain, function, and movement, respectively.

Cemented revision Charnley low-friction arthroplasty in patients with rheumatoid arthritis.

We assessed 41 patients with rheumatoid arthritis (47 hips) who had had revision hip arthroplasty, at an average follow-up of 7 years 4 months (2 to 19). The clinical results were excellent or satisfactory in 43 hips. Radiologically, 45 stems were secure. Fifteen sockets (36.6%) were radiologically loose. Three hips required rerevision. Socket failure is the predominant problem in rheumatoid patients after cemented revision arthroplasty.

One-stage revision of infected total hip replacements with discharging sinuses.

We report a prospective study of 57 one-stage cemented revisions of total hip replacement for deep infection with an actively discharging sinus. The average follow-up was 7 years 4 months. Seven patients had required rerevisions, but at latest follow-up, infection was under control in 49 (86%). A discharging sinus is not, in itself, a contraindication to one-stage revision of a hip replacement.

Long-term results of cemented Charnley revision arthroplasty for fractured stem.

A prospective study of 125 cemented revisions for fractured stem, with a minimum follow-up time of one year nine months and a mean follow-up time of eight years, was performed. All arthroplasties were revised using Charnley components. At the most recent follow-up evaluation, 67.2% of patients were pain free and 22.4% had only mild or occasional discomfort. Radiographically, 107 stems (85.6%) were well fixed, six (4.8%) were definitely loose, and 12 (9.6%) were possibly loose. Thirteen hips (10.4%) required a further revision. Survivorship of the stem at the end of 11 years was 90.4%. Long-term results of cemented revision for fractured stem are very satisfactory.

Revision hip arthroplasty. Can the octogenarian take it?

Fifty-six patients over the age of 80 undergoing revision hip arthroplasty in 57 hips were reviewed. The average age of the patients at the time of surgery was 81 years 6 months and the mean follow-up period was 2 years 6 months. No complications were seen in 21 patients. The complication encountered in the others were medical in 35 and procedure-related in 15. The preoperative risk factor rating (American Society of Anesthesiologists classification) correlated very well with the incidence and grading of medical complications. This correlation was significant, emphasizing the importance of strict preoperative medical and anesthetic assessment in this group of patients. The mean d'Aubigne and Postel hip score improved from 2.8, 2.2, and 3.4 to 5.6, 4.8, and 4.9 after revision surgery.

Reduction of postoperative blood loss after press-fit condylar knee arthroplasty with use of a femoral intramedullary plug.

In a prospective study of eighty press-fit condylar knee arthroplasties performed with cement, we compared the postoperative blood loss in forty patients in whom the defect left by the femoral intramedullary alignment rod had been left open with the blood loss in forty patients in whom the defect had been closed with a plug of cement. The patients in the open-defect group had significantly more blood loss (mean, 1002 milliliters) in the first twenty-four hours after the operation than the closed-defect group (mean, 752 milliliters) (p < or = 0.01). The total postoperative blood loss was also significantly greater in the open-defect group (mean, 1536 milliliters) than in the closed-defect group (mean, 1215 milliliters) (p = 0.02).
