[Early incision, decompression and screw fixation for the treatment of Lisfranc injuries with foot osteofascial compartment syndrome].

Objective: To explore clinical effect of early incision and decompression combined with screw fixation in treating Lisfranc injury and foot osteofascial compartment syndrome.

Methods: Clinical data of 5 patients with Lisfranc injury and foot osteofascial compartment syndrome were retrospective analysized from January 2017 to December 2018, including 4 males and 1 female, aged from 19 to 62 years old. All patients were suffered from closed injuries.

Surgical or nonsurgical treatment for nontraumatic rotator cuff tears: Study protocol clinical trial.

Background: The optimal treatment for symptomatic, nontraumatic rotator cuff tear is unknown. The primary aim of this randomized controlled trial is to compare functional improvement after surgical and conservative treatment of nontraumatic rotator cuff tears.

Methods: This is a single-centre, randomized clinical trial with a follow-up of 12 months.

[Preparation and biocompatibility of a novel strontium-containing calcium sulfate].

Objective: To prepare a novel strontium-containing calcium sulfate and assess its and biocompatibility.

Methods: A novel strontium-containing α-calcium sulfate hemihydrate (Sr-caS) bone substitute as prepared with hydrothermal reaction and examined for X-ray diffraction (XRD), Fourier transform infrared (FTIR) and thermogravimetric differential scanning calorimetric (TG-DSC) patterns. The biocompatibility of the material was evaluated by in vitro cytotoxicity test in L-929 cells, hemolysis test of blood, and in vivo implantation test in SD rats.

Operative vs. nonoperative treatment for comminuted proximal humeral fractures in elderly patients: a current meta-analysis.

Objective: The aim of this study was to compare the effect of operative vs. nonoperative treatment for comminuted proximal humeral fractures in elderly patients regarding clinical results, complications, and additional surgeries.

Methods: Six electronic databases (Medline, Embase, Clinical, Ovid, Biosos, and Cochrane Central Register of Controlled Trials) were systematically searched to identify randomized controlled trials (RCTs).

A novel resorbable strontium-containing α-calcium sulfate hemihydrate bone substitute: a preparation and preliminary study.

Distraction osteogenesis after aggrieved bone segment resections is promising in the treatment of bone tumors and osteomyelitis. However, there is ambiguity with regard to the optimal choice of bone substitute, with biodegradability and excellent bone repair performance constituting key requirements. The purpose of this study was to develop a novel resorbable strontium-containing α-calcium sulfate hemihydrate (Sr-CaS) bone substitute to provide an alternative option for surgeons that better meets these requirements.

Are platelet concentrates an ideal biomaterial for arthroscopic rotator cuff repair? A meta-analysis of randomized controlled trials.

Purpose: The present study aims to conduct a meta-analysis of Level I evidence studies to investigate the efficacy of concomitant platelet concentrate (PC) used in arthroscopic rotator cuff repair.

Methods: We systematically searched electronic databases to identify randomized controlled trials (RCTs) evaluating the role of PC augmentation in arthroscopic rotator cuff repairs for patients with full-thickness tears. The search strategy followed the requirements in the Cochrane Library Handbook.

Efficacy and safety of single-dose local infiltration of analgesia in total knee arthroplasty: a meta-analysis of randomized controlled trials.

Purpose: To examine the efficacy and safety of single-dose local infiltration of analgesia (LIA) for post-operative pain relief in total knee arthroplasty (TKA) patients.

Methods: A systematic electronic literature search (up to Aug 2013) was conducted to identify the RCTs that address the efficacy and safety of single-dose LIA in the pain management after TKA. Subgroup analysis was conducted to determine changes of visual analog score (VAS) values at six different postoperative time points.

Effect of treadmill exercise timing on repair of full-thickness defects of articular cartilage by bone-derived mesenchymal stem cells: an experimental investigation in rats.

Objective: Current medical practice for the treatment of articular cartilage lesions remains a clinical challenge due to the limited self-repair ability of articular cartilage. Both experimental and clinical researches show that moderate exercise can improve articular cartilage repair process. However, optimal timing of moderate exercise is unclear.

Mini-incision versus standard incision total hip arthroplasty regarding surgical outcomes: a systematic review and meta-analysis of randomized controlled trials.

Purpose: It remains controversial whether mini-incision (MI) benefits patients in total hip arthroplasty (THA). We performed a meta-analysis of randomized controlled trials (RCTs) to assess the effects of MI on surgical and functional outcomes in THA patients.

Methods: A systematic electronic literature search (up to May 2013) was conducted to identify RCTs comparing MI with standard incision (SI) THA.

Single-bundle versus double-bundle anterior cruciate ligament reconstruction: an up-to-date meta-analysis.

Purpose: The aim of this meta-analysis was to compare the results of arthroscopic single-bundle and double-bundle anterior cruciate ligament (ACL) reconstruction.

Methods: We systematically searched electronic databases to identify randomised controlled trials (RCTs) in which arthroscopic single-bundle was compared with double-bundle for ACL reconstruction. The search strategy followed the requirements of the Cochrane Library Handbook.
