Abstract
To evaluate the functional outcome of a partial lateral facetectomy in patellar-retaining
total knee arthroplasty (TKA), we retrospectively analyzed 63 knees of 59 patients
who underwent TKA for primary knee osteoarthritis with (32 knees of 30 patients, group
1) or without (31 knees of 29 patients, group 2) patellar facetectomy from September
2005 to July 2007. All cases were followed up for a minimum of 36 months. Although
there was no significant differences between the 2 groups in preoperative patellar
score, Western Ontario and McMaster Universities score, knee and function scores,
postoperatively, group 1 showed more significant improvements in the scores and fewer
lateral patellar osteophytes in radiographs than group 2. A partial lateral facetectomy
is an effective way to improve the function of patellar-retaining TKA in patients
with primary osteoarthritis.
