The results of the study suggest that patients do well with or without patellar resurfacing. In both groups there was a significant reduction in pain after surgery. Overall knee pain decreased from moderate or severe preoperatively to mild or none postoperatively in both groups, and there was no difference between groups. In both groups, postoperative ROM was increased at 1 year postoperatively. Overall the HSS score improved dramatically in both groups from a preoperative level of poor to one of excellent at 1 and 2 years.
Patients show increased satisfaction, improved mobility and generally better quality of life.
The complication rate was similar in the 2 groups. The rate represented the overall problems experienced by the patients and not just patella-specific complications. Overall, we found no difference between patients who underwent patellar replacement and those who did not, suggesting that the indications for patellar replacement be should be critically reviewed. The literature suggests that patellar resurfacing should be considered in patients with rheumatoid arthritis, patients with preoperative patellofemoral pain, elderly, low-demand patients, and intraoperatively demonstrated advanced changes to the patella. 10 Picetti and colleagues 8 also added that patient height more than 160 cm and weight more than 60 kg be considered a relative indication to resurface the patella.
