[Medium- and long-term effectiveness of hip revision with SL-PLUS MIA stem in patients with Paprosky type - femoral bone defect].

Objective: To investigate the medium- and long-term effectiveness of hip revision with SL-PLUS MIA stem in patients with Paprosky typeⅠ-Ⅲ femoral bone defect.

Methods: Between June 2012 and December 2018, 44 patients with Paprosky typeⅠ-Ⅲ femoral bone defect received hip revision using SL-PLUS MIA stem. There were 28 males and 16 females, with an average age of 57.

Conservative femoral revision using short cementless stems with a tapered rectangular shape for selected Paprosky II-IV bone defects: an average seven-year follow-up.

Background: The use of long stems for severe femoral bone defects is suggested by many scholars, but it is associated with further bone loss, intraoperative fracture, increased surgical trauma, and complications. With better bone retention, simple and quick surgical procedures, and minimal complications, the short cementless stems with a tapered rectangular shape may be an alternative for femoral revision. This study aimed to evaluate the results of this type of stem in treating selected Paprosky II-IV bone defects.

One-stage revision using intra-articular carbapenem infusion effectively treats chronic periprosthetic joint infection caused by Gram-negative organisms.

Gram-negative periprosthetic joint infection (PJI) has been poorly studied despite its rapidly increasing incidence. Treatment with one-stage revision using intra-articular (IA) infusion of antibiotics may offer a reasonable alternative with a distinct advantage of providing a means of delivering the drug in high concentrations. Carbapenems are regarded as the last line of defense against severe Gram-negative or polymicrobial infection.

Effects of Adding Morphine to Periarticular Infiltration Analgesia Combined with Single Dose Epidural Morphine in Total Knee Arthroplasty: A Randomized Controlled Study.

Objective: Morphine plays an important role in postoperative analgesia after total knee arthroplasty (TKA). However, there are limited data that investigate the administration ways of morphine. To evaluate the efficacy and safety of adding morphine to periarticular infiltration analgesia (PIA) combined with single-dose epidural morphine for the patients undergoing TKA.

[One-stage revision using intra-articular vancomycin infusion effectively treats chronic prosthetic joint infection caused by ].

To investigate the clinical effects of one-stage revision combined with intra-articular infusion of vancomycin in the treatment of chronic prosthetic joint infection (PJI) caused by . From May 2013 to June 2020,the clinical data of 9 patients (2 males and 7 females) with chronic PJI treated with one-stage revision using intra-articular infusion of vancomycin at Department of Orthopaedics,First Affiliated Hospital of Xinjiang Medical University were retrospectively analyzed,including 8 hips and 1 knee.A total of 9 patients with age of (63.

[Effectiveness of structural bone graft in total hip arthroplasty for Hartofilakidis type developmental dysplasia of the hip].

Objective: To summarize the effectiveness of acetabulum reconstruction with autologous femoral head structural bone graft in total hip arthroplasty (THA) for Hartofilakidis type Ⅱ developmental dysplasia of the hip (DDH).

Methods: A clinical data of 24 patients (27 hips) with Hartofilakidis type Ⅱ DDH, who underwent acetabulum reconstruction with autologous femoral head structural bone graft in primary THA between October 2012 and October 2020, was retrospectively analyzed. There were 3 males and 21 females, with an average age of 40 years (range, 20-58 years).

[Short-term effectiveness of Mako robot-assisted total hip arthroplasty via posterolateral approach].

Objective: To explore the short-term effectiveness of Mako robot-assisted total hip arthroplasty (THA) via posterolateral approach.

Methods: The clinical data of 64 patients (74 hips) treated with Mako robot-assisted THA via posterolateral approach (robot group) between May 2020 and March 2021 were retrospectively analyzed and compared with the clinical data of 52 patients (55 hips) treated with traditional THA via posterolateral approach (control group) in the same period. There was no significant difference in general data such as gender, age, side, body mass index, disease type, and preoperative Harris score between the two groups ( >0.

Effective Treatment of Single-Stage Revision Using Intra-Articular Antibiotic Infusion for Polymicrobial Periprosthetic Joint Infection.

Background: The treatment of polymicrobial periprosthetic joint infection (PJI) confronted distinct challenges. No reports have assessed the efficacy of local antibiotic delivery combined with 1-stage exchange in polymicrobial PJI.

Methods: Between January 2013 and December 2018, we retrospectively analyzed the data of 126 patients, including 19 polymicrobial PJIs and 107 monomicrobial PJIs, who underwent single-stage revision using intra-articular antibiotic infusion.

Total knee arthroplasty with the least-constrained implant possible for type II valgus knee > 20°: a 3-14 years' follow-up.

Objective: To estimate the midterm outcome of primary total knee arthroplasty for severe valgus deformity using selective release of tight lateral structures and the least-constrained implant.

Methods: We performed total knee arthroplasty on 65 consecutive type II knees with valgus deformity> 20°. Surgery was done via a medial parapatellar approach.
