Hemiepiphyseal Stapling for Ankle Valgus in Multiple Hereditary Exostoses
Arthritis in Other Joints Worsens Outcomes of Knee Replacement Surgery*
SAN DIEGO – It’s not unusual for total knee replacement patients to have arthritis in other joints, and it negatively impacts surgery outcomes, Toronto researchers have found.
In their study, 420 of 494 knee replacement patients (85%) reported problems in at least one other joint. Those with foot or ankle arthritis had a significantly reduced chance of achieving an MCID (Minimally Clinically Important Difference) on postoperative WOMAC (Western Ontario and McMaster Universities Osteoarthritis Index) pain and function scores (odds ratio pain 0.32, 95% confidence interval 0.185-0.544; OR function 0.53, 95% CI 0.303, 0.940).
Patients who reported neck problems also had reduced odds of achieving an MCID on physical function WOMAC scores (OR 0.37, 95% CI 0.183, 0.726).
"It’s not surprising that ankles and feet [were] significant. [They] impact activities for which lower-extremity joints are involved. How the upper extremities are associated here, in particular the neck, is unclear," said lead investigator Anthony Perruccio, Ph.D., an epidemiologist and research scientist at the Toronto Western Research Institute.
Because patients with neck problems also saw less improvement in fatigue, anxiety, depression, and pain, there may also be a mental health component, he said.
Whatever the case, the lesson is to treat the whole patient, not just the knee. Referrals to other types of providers are appropriate, including physiotherapists and mental health counselors as needed, said Dr. Perruccio.
"There’s more than just the one joint that’s involved here. Outcomes could be improved if a more holistic approach to osteoarthritis management were considered," he said.
All 494 patients had primary, unilateral knee replacements secondary to osteoarthritis. Their mean age was 65, 65% were women, and almost half were obese.
The patients filled out several surveys before their operations, including WOMAC and other pain and function scales plus the Profile of Mood States (POMS) fatigue scale, the Knee injury and Osteoarthritis Outcome Score (KOOS) sports and recreation scale, and the Hospital Anxiety and Depression Scale (HADS). They also pointed out on a homunculus diagram which joints were causing trouble.
Almost half (46%) reported pain on most days in four or more joints in addition to their operative knee. The nonoperative knee was a problem for 57%, elbows/wrists/hands were problematic for 49%, ankles/feet for 36%, the back for 31%, shoulders for 29%, hips for 25%, and neck for 22%. Just 15% said only their operative knee was symptomatic.
A year after their operation, patients took the surveys again. Those with back problems tended to see less improvement in fatigue at 1 year. Those with ankle or foot arthritis – in addition to diminished returns on pain and function – also saw less improvement than others in depression and sports and recreation scores.
The congress was sponsored by the Osteoarthritis Research Society International. Dr. Perruccio said he had no relevant financial disclosures. The work was funded by the Canadian Institutes of Health Research.

Gastric Bypass May Increase Long-Term Fracture Risk
Major Finding: The fracture risk for gastric bypass surgery patients was 2.3-fold greater than that for the general population.
Data Source: A retrospective study of 258 patients who underwent bariatric surgery between 1985 and 2004.
Disclosures: Dr. Kennel reported that he and his coinvestigators have no significant financial relationships to report.
BOSTON – Gastric bypass surgery appears to be linked to increased long-term fracture risk, based on a retrospective study of 258 bariatric surgery patients.
“Bariatric surgery results in an increased risk of fractures. We think the important take-home point here is that we need to start looking at the skeleton as one of those key areas for long-term follow-up,” Dr. Kurt Kennel said at the meeting.
The fracture risk for bariatric surgery patients in this study was 2.3 times greater than that for individuals who did not have bariatric surgery, reported Dr. Kennel of the endocrinology department at the Mayo Clinic in Rochester, Minn.
“We have questions about what this means in the long term,” said Dr. Kennel. In this study, the mean time to first fracture was 6 years, with a mean follow-up of 9 years. However, in much of the current literature on bariatric surgery, patients are followed only 1–2 years and the only issues addressed are related to surgery or weight.
“Some issues – like bone, for example – may not show the manifestations of these effects for many years and therefore we may be missing some of those effects,” said Dr. Kennel.
The researchers used data from the Rochester Epidemiology Project to conduct a retrospective study of fracture incidence. REP connects medical records from the Mayo Clinic, local hospitals, and local private practices. The study included data from 258 patients, who underwent a first bariatric surgery between 1985 and 2004 at the Mayo Clinic.
Fractures were expressed in standardized incidence ratios that compare the number of observed fractures to the number of expected fractures by skeletal site.
Expected fracture data were derived by applying age- and sex-specific incidence rates from the local population to the age- and sex-specific person-years of follow-up.
The average age of the bariatric surgery patients was 44 years and most (83%) were female. Following bariatric surgery, 79 patients experienced 132 fractures.
Bariatric surgery patients had an increased risk of fracture at nearly all of the skeletal sites studied, not just in weight-bearing bones.
Also of note, 94% of these patients had undergone gastric bypass procedures. Dr. Kennel attributed this to the time frame used in the study.
Other bariatric surgical procedures – such as adjustable gastric banding and sleeve gastrectomy – are more recent developments. Dr. Kennel acknowledged that different bariatric procedures might yield different fracture risks.
The increased rate of fractures “suggests that structural and biochemical changes in bone that are observed after bariatric surgery are clinically important.
Clinicians should discuss bone health with patients who have undergone or are considering bariatric surgery.”

WHO Data Shows Worldwide Uptick in Osteoarthritis
Updated World Health Organization estimates are showing a downward trend in the incidence of gout in North America among 65-year-olds, but men in that age group on the continent are far more likely to suffer from gout than are men in Africa.
That’s a sampling of the updated data on a host of musculoskeletal disorders worldwide, including rheumatoid arthritis, said Dr. Lyn March at the Annual European Congress of Rheumatology.
She presented a preliminary report from the Musculoskeletal Expert Group that’s part of the new Global Burden of Diseases, Injuries, and Risk Factors Study, which began in the spring of 2007. This is the first major effort since the original Global Burden of Disease in 1990 study to carry out a complete systematic assessment of the data on all diseases and injuries, and to produce comprehensive and comparable estimates of the burden of diseases, injuries, and risk factors for two time periods (1990 and 2005), according to the WHO. The project is due to produce final estimates in the spring, said Dr. March of the Royal North Shore Hospital in Sydney.
Dr. March said the specific aims for the Musculoskeletal Expert Group are to include more population-based self-report data; to develop health-state descriptions for different levels of severity of osteoarthritis, rheumatoid arthritis, back pain, neck pain, gout, and other musculoskeletal disorders; and to update systematic literature reviews of incidence, prevalence, and mortality risk for these conditions. The group will also evaluate bone mineral density (g/cm2) as a risk factor for disability-adjusted life-year (DALY) burden, "which will put the [degenerative] bone condition on the map for policy making," she said.
"The methodology employed in the systematic review, development of lay health state descriptions, and generation of data estimates for calculating [DALYs] will be revealed," Dr. March said.
In 2000, the beginning of what the WHO declared "the Bone and Joint Decade," results from the previous Global Burden of Disease (GBD) study reported that rheumatoid arthritis accounted for 0.3% of global DALYs (a time-based measure that combined years of life lost to premature mortality and years of life lost to time lived in health states of less-than-ideal health). "These data enable, in part, an evaluation of the impact of the Bone and Joint Decade and the setting of the research agenda for the next decade," Dr. March said.
The GBD study investigated the incidence of 109 diseases and injuries and 10 risk factors across eight World Bank regions. In 2000, the WHO reported that osteoarthritis accounted for 1.1% of global DALYs, ranking 19th among all diseases and disorders, and rheumatoid arthritis accounted for 0.3% of DALYs. All musculoskeletal disorders combined had a prevalence of 2.1% of the worldwide population and ranked 12th in DALYs among all disorders, according to Dr. March. Preliminary data from the 2005 study show trends toward increases in the prevalence of osteoarthritis of the knee and hip, rheumatoid arthritis, and other musculoskeletal disease, and slight decreases in low-back pain and gout, she said, noting that the findings will likely have policy implications.
A 2005 update reported that musculoskeletal disorders are more common in developed countries.
Dr. March had no disclosures to report. The study received funding from the Bill and Melinda Gates Foundation and the Australian Commonwealth Government’s Department of Health and Aging.
