Material and Methods: Professional sports persons aged between 16-50 years operated for ACL tear using BPTB, free STG and STGPI grafts with minimum follow-up of two years were identified from hospital records. Patients with associated knee injuries were excluded. Patients, divided in three groups according to graft used, were compared in terms of mechanical stability (arthrometric examination KT-1000 score), functional outcome (Lysholm Score), return to sports activity (Tegner score and difference in thigh circumference) and degenerative changes (KL grading).
Results: BPTB graft group was found to be better than free STG and STGPI graft groups in terms of KT-1000 score. There was no statistically significant difference among the groups in terms of Lysholm score, Tegner score, difference in thigh circumference and KL grading.
Conclusion: BPTB graft is better than free STG and STGPI grafts in terms of knee stability. When compared for patient reported outcome, return to sports activity, osteoarthritic changes and graft failure there is no significant difference among the three types of grafts.
Materials and Methods: A double-blind, randomized controlled trial was conducted with 100 patients who wanted single-rooted teeth to be extracted (which failed endodontically). The participants have been randomized into two equal groups named as - (i) a periotome group (ii) and a piezotome group. Duration of the surgery, postoperative pain within 7 days, complications (if any) associated with the extraction process were performed as a part of clinical assessment. Bone loss has been analyzed 6 months after the surgery radiographically. The data have been recorded and analyzed using the version 22.0 of the SPSS software package.
Results: All parameters in the periotome category (P < 0.05) were statistically significant except for bone loss and gingival laceration in comparison to piezotome group. In the piezotome group, a longer time was observed for surgery and delayed pain control was achieved. In our study, we found statistically significant more marginal bone loss in piezotome group in comparison with periotome group.
Conclusion: The findings of this study indicate that for intraoperative and postoperative comfort periotome could be used as a safer and cheaper option for atraumatic extractions but piezosurgery may prove as a better choice soon for surgeries in the maxillofacial region to maintain soft-tissue integrity.
