The Use of Viscosupplementation for the Treatment of Patients With Persistent Non-mechanical Pain Status-post Partial Menisectomy
The investigators' objective is to analyze a group of patients who have had a partial
meniscectomy but continue to have knee pain after surgery with a double-blind, randomized
prospective study comparing the use of Hylan G-F 20(single injection of a
viscosupplementation) versus placebo injection. The investigators would expect patients who
receive the treatment (Hylan G-F 20) to have lower pain compared to the patients who were in
the placebo group (had the needle injected into the knee but no medication or substance
injected) since Hylan G-F 20 has been shown to decrease pain in arthritic patients.
A great majority of patients who have a partial menisectomy for mechanical symptoms do well
with full return of function without pain. There is a sub-group of patients who are found
to have Grade II- III chondromalacia lesions (deemed arthritic) at the time of surgery that
have persistent generalized "arthritic-type" pain despite relief of their mechanical
symptoms. To date, there are no published studies analyzing if this treatment is better
than no treatment in this group of patients. We would expect patients who receive the
treatment (Hylan G-F 20) to have lower pain compared to the patients who were in the placebo
group (had the needle injected into the knee but no medication or substance injected) since
Hylan G-F 20 has been shown to decrease pain in arthritic patients.
