In Total Knee Arthroplasty, Patellar Plasty With Clinical Comparative Study Of Patella Replacement

Objective: Compared to patients with osteoarthritis of knee arthroplasty patellar laminoplasty with clinical effect after patellar replacement.Methods: In our hospital from 2007 to 2013, 186 cases of knee osteoarthritis knee showed that replacement of patients with postoperative follow-up. According to the treatment of patella in different ways can be divided into: patella replacement with patellar plasty group, including 67 cases of patellar replacement(including double knee replacement in 11);Line of patella plasty of 65 patients(including 8 cases of knees),Two sets of minimum follow-up of 2 years, compared to two groups the knee society score(KSS), HSS score, Bristol patellar scores, knee joint activity, in time, patient satisfaction, cost of treatment, postoperative cases of patellar line issue revision procedures and analysis the incidence of postoperative knee pain, and review the X line piece of implants. At the same time, the score between two groups(KSS/HSS), Mr.Feller patellar scores, knee joint activity, in time, patient satisfaction, cost of treatment,postoperative undergo revision procedures for patellar problem cases and analysis of incidence of postoperative knee pain before there was no significant difference, but in patellar substitution groups appear in the case of patients with your knees in front of the right knee pain caused by poor patellar position, after the renovation of patella replacement.Results: 132 cases(186 knees) with complete follow-up data. 67 cases of patellar keratoplasty, 65 cases of patellar replacement, 31 months ~ 24 months of follow-up time,average(27 + /- 2.7) months.In patients with patellar substitution groups on postoperative satisfaction 41.2% patients choose very satisfied and patellar plasty groups only 30.6% of the patients choose very satisfied, but very satisfied and happy with two percentage addition no statistical differences in the two groups.Conclusions: Handling of the patella in total knee arthroplasty patella replacement and forming these two ways of postoperative effect.After patellar replacement for patellar for patellar problems caused by knee pain provides a very good treatment.
