Comparison Patellar Resurfacing Versus Patelloplasty for Treatment of Patellofemoral Joint Osteoarthritis in Total Knee Replacement: A Randomized Controlled Trial

Background: Total knee arthroplasty (TKA) is the recom-mended treatment to correct deformity, relieve pain, and re-store normal biomechanics in osteoarthritis of the knee joint. We aimed to compare between patellar resurfacing versus pa-telloplasty for treatment of patellofemoral joint osteoarthritis in total knee replacement. Patients and Methods: This randomized clinical study was carried out on 60 orthopaedic patient’s clinic suffering from advanced osteoarthritis knee joint, both gender, and aged from 35 to 65 years old, presented at the orthopedic clinic. We were randomly allocated into two groups preoperatively for treat-ment with either (group I) or (group II). Group (A) was man-aged with patellar resurfacing and Group (B) was managed with Patelloplasty. Results: Regarding the postoperative KSS, there was a significant difference between both groups regarding pain, alignment (p<0.05), ROM was significantly higher in group (I) compared to group (II) (p=0.036). Lateral patellar place-ment was significantly higher in group B compared to group A (p=0.036). Patellar thickness was significantly higher in group B compared to group A (p<0.001). Conclusions: Total knee prosthesis, patellar resurfacing is a better option compared with patelloplasty for patellofemo-ral osteoarthritis treatment regarding post operative different clinical scores specially anterior knee pain and ROM and func-tional knee score walking distance, stairs climbing, walking aids used.
