Introduction: Variety of techniques has been introduced to improve the outcomes of total knee arthroplasty (TKA). Choosing the best technique has always been a challenge for Orthopaedic surgeons, as each technique has its own advantages and disadvantages. The aim of this study is to compare the efficacy of patient specific guides with manual instrumentations regard with, retaining the neutral alignments.
Materials and methods: Patients have been allocated into two groups. Each group has been operated with different technique, one using the patient-specific guides (PSG) and the other group with the manual instrumentations (MI). Coronal and sagittal alignments have been evaluated in all the patients. A comparison in duration of the surgery and tourniquet time were also been performed.
Results: 289 knees were evaluated, 250 operated with MIs and 29 knees with PSGs. The duration of the surgery and tourniquet time were significantly longer using manual instrumentations. The results regarding retaining the neutral alignments in coronal and sagittal planes had no difference.
Conclusion: The efficacy of TKA in retaining the neutral alignment in sagittal and coronal plane has no significant difference using either technique in hands of an experienced surgeon. But the surgery and tourniquet times have significantly decreased using PSGs.
