Women and arthritis sufferers have poorer short-term recovery from arthroscopic knee surgery.The factors associated with poor short-term recovery from knee surgery appear to be different than those found to mar long-term outcome from the same surgery.
We found that women showed poorer short-term recovery than men in the first year following arthroscopic meniscal tear removal surgery, and people with osteoarthritis also did not do as well as others, says principal investigator Peter Fabricant, BS, a medical student at Yale University School of Medicine in New Haven, Conn.
The factors associated with a poorer long-term outcome, such as larger tear size, greater amount of tissue removed, advanced patient age, and higher Body Mass Index, are not the same as those we can associate with short-term surgical recovery.
The meniscus is the shock-absorbing tissue that cushions the knee joint preventing the bones from rubbing. Tears in this tissue can cause pain and loss of function.
In arthroscopic partial meniscectomy, the surgeon inserts small surgical instruments and a camera through tiny incisions in the knee to remove torn tissue. An estimated 636,000 arthroscopic knee procedures are performed annually, according to the American Academy of Orthopaedic Surgeons.
Fabricant and colleagues at Yale University studied 126 patients who underwent arthroscopic partial meniscectomy to assess the impact of obesity, age, gender, amount of tissue removed, and degenerative joint changes on short-term recovery.
They found that being female and the extent of osteoarthritis were associated with a less-than-optimal first-year recovery. Other studies have shown that advanced age, obesity, and the amount of meniscal tissue removed all negatively affect long-term outcome from arthroscopic meniscal repair.
In our study these variables did not affect short-term recovery. Conversely, gender and o
