Randomized Controlled Trial
Subsartorial adductor canal vs femoral nerve block for analgesia after total knee replacement.
Providing effective analgesia for total knee arthroplasty (TKA) patients remains challenging. Femoral nerve block (FNB) offers targeted pain control; however, its effect on motor function, related fall risk and impact on rehabilitation has been the source of controversy. Adductor canal block (ACB) potentially spares motor fibres of the femoral nerve, but the comparative effect of the two approaches has not yet been well defined due to considerable variability in pain perception. Our study compares both single-shot FNB and ACB, side to side, in the same patients undergoing bilateral TKA. ⋯ Although we could not confirm a benefit in motor function between ACB and FNB, given the equivalent analgesic potency combined with its potentially lower overall impact if neuropraxia should occur, ACB may represent an attractive alternative to FNB.

Randomized Controlled Trial Multicenter Study Comparative Study
A prospective, randomised, controlled multicentre study comparing cervical disc replacement with anterior cervical decompression and fusion.
Total cervical artificial disc replacement (TDR) simulates normal disc structure, thus avoiding the drawbacks of anterior cervical decompression and fusion (ACDF). This prospective, randomized, controlled and multicentre study aimed to evaluate clinical and radiographic outcomes by comparing cervical disc replacement using Mobi-C disc prostheses with ACDF. ⋯ Although ACDF may increase the risk of additional surgery, clinical outcomes indicated that both Mobi-C artificial cervical disc replacement and ACDF were reliable. Radiographic data showed that ROM of the cervical spine, FSU angle and treated and adjacent segments were relatively better reconstructed and maintained in the Mobi-C group compared with those in the ACDF group.

Randomized Controlled Trial
Prospective randomized trial comparing open reduction and internal fixation with minimally invasive reduction and percutaneous fixation in managing displaced intra-articular calcaneal fractures.
Managing displaced intra-articular calcaneal fractures remains controversial. A prospective randomised trial was undertaken to compare open reduction and internal fixation (ORIF) with minimally invasive reduction and percutaneous fixation (MIRPF). ⋯ MIRPF is associated with fewer wound-healing problems, better functional outcome and earlier return to work compared with ORIF.

Randomized Controlled Trial Comparative Study
Management of distal third tibial fractures: comparison of combined internal and external fixation with minimally invasive percutaneous plate osteosynthesis.
The objective of this study was to compare combined internal and external fixation (CIEF) with minimally invasive percutaneous plate osteosynthesis (MIPPO) in the treatment of distal third tibial fractures, and explore the benefits and defects of these two techniques. ⋯ Our results indicated that both CIEF and MIPPO were all efficient methods for treating distal third tibial fractures. However, CIEF had the advantages of a shorter operating and radiation time, less wound complication and ankle pain, less secondary operations for implant removal and easier removal of the implants.

Randomized Controlled Trial Comparative Study
Treatment of distal tibial shaft fractures by three different surgical methods: a randomized, prospective study.
A few studies focused on the methods of treatment for displaced distal tibial shaft fractures have been published, all of which compared two different methods. In this randomized, prospective study, we aimed to compare minimally invasive plate osteosynthesis, locking intramedullary nail stabilization and external fixation combined with limited open reduction and absorbable internal fixation for distal tibial shaft fractures by assessing complications and secondary procedures. ⋯ We consider that the minimally invasive plate osteosynthesis, locking intramedullary nail stabilization and external fixation combined with limited open reduction and absorbable internal fixation techniques are all efficient methods for treating distal tibia fractures. With its wide indications, external fixation combined with limited open reduction and absorbable internal fixation leads to minimal soft tissue complication, good functional result and no local soft tissue irritation or implant removal.
