The use of 3D printing has become increasingly popular and has been widely used in orthopaedic surgery. There has been a trend towards an increasing number of publications in this field, but existing literature incorporates limited high-quality studies, and there is a lack of reports on outcomes. The aim of this study was to perform a scoping review with Level I evidence on the application and effectiveness of 3D printing. A literature search was performed in PubMed, Embase, and Web of Science databases. The keywords used for the search criteria were ((3d print*) OR (rapid prototyp*) OR (additive manufactur*)) AND (orthopaedic). The inclusion criteria were: 1) use of 3D printing in orthopaedics, 2) randomized controlled trials, and 3) studies with participants/patients. Risk of bias was assessed with Cochrane Collaboration Tool and PEDro Score. Pooled analysis was performed.Aims

Aims. Arthroscopically controlled fracture reduction in combination
with percutaneous screw fixation may be an alternative approach
to open surgery to treat talar neck fractures. The purpose of this
study was thus to present preliminary results on arthroscopically
reduced talar neck fractures. Patients and Methods. A total of seven consecutive patients (four women and three men,
mean age 39 years (19 to 61)) underwent attempted surgical treatment
of a closed Hawkins type II talar neck fracture using arthroscopically
assisted reduction and percutaneous screw fixation. Functional and
radiological outcome were assessed using plain radiographs, as well
as weight-bearing and non-weight-bearing CT scans as tolerated.
Patient satisfaction and pain sensation were also recorded. Results. Primary reduction was obtained arthroscopically in all but one
patient, for whom an interposed fracture fragment had to be removed
through a small arthrotomy to permit anatomical reduction. The quality
of arthroscopic reduction and restoration of the talar geometry
was excellent in the remaining six patients. There were no signs
of talar avascular necrosis or subtalar degeneration in any of the
patients. In the whole series, the
Aims. The objective of this study was to compare early postoperative
functional outcomes and time to hospital discharge between conventional
jig-based total knee arthroplasty (TKA) and robotic-arm assisted
TKA. Patients and Methods. This prospective cohort study included 40 consecutive patients
undergoing conventional jig-based TKA followed by 40 consecutive
patients receiving robotic-arm assisted TKA. All surgical procedures
were performed by a single surgeon using the medial parapatellar
approach with identical implant designs and standardized postoperative inpatient
rehabilitation. Inpatient
Aims. This study investigated the influence of body mass index (BMI)
on patients’ function and quality of life ten years after total
knee arthroplasty (TKA). Patients and Methods. A total of 126 patients who underwent unilateral TKA in 2006
were prospectively included in this retrospective study. They were
categorized into two groups based on BMI: < 30 kg/m. 2. (control)
and ≥ 30 kg/m. 2. (obese).
Aims. The present study aimed to investigate the long-term functional
results of scapulothoracic fusion using multifilament cables in
patients with facioscapulohumeral dystrophy (FSHD) to identify if
the early improvement from this intervention is maintained. Patients and Methods. We retrospectively investigated the long-term outcomes of 13
patients with FSHD (18 shoulders) in whom scapulothoracic fusion
using multifilament cables was performed between 2004 and 2007.
These patients have previously been reported at a mean of 35.5 months
(24 to 87). There were eight men and five women with a mean age
of 26 years. Their mean length of follow-up of our current study
was 128 months (94 to 185). To evaluate long-term functional results,
the range of shoulder flexion and abduction, Quick Disabilities
of the Arm, Shoulder and Hand (QuickDASH) scores were analyzed with
a comparison of preoperatively, interim and at the final outcomes. The
fusion was examined radiographically in all. Results. The complication rate was 33% (six of 18 scapulothoracic fusions)
in 13 patients, which comprised failure of fusion in four shoulders
(four patients) all occurring within the first year postoperatively.
In two shoulders (one patient) wound problems arose due to attribution
from the cables which required shortening but the fusion developed satisfactorily.
At the final examination, the mean QuickDASH score and range of
movement significantly improved in all but one patient (p < 0.001,
p < 0.001 and p < 0.001). In the comparison of 13 patients’
mid- and long-term results, the mean QuickDASH score decreased from
9.8 (. sd. 6.7; 3 to 26) in the third year to 9.1 (. sd. 5.6;
3 to 22) in the tenth year (p = 0.7); the mean range of shoulder
flexion and abduction decreased from 129° (. sd. 22°; 90°
to 160°) and 124° (. sd. 12; 100° to 150°) at the mid-term
to 103° (. sd. 12°; 80° to 120°) and 101° (. sd. 8°;
80° to 120°) at the long-term, respectively (p = 0.78 and p = 0.65). Conclusion. Scapulothoracic fusion using a multiple cabling method can confer
a considerable improvement in clinical and
Studies on long-term patient-reported outcomes after open surgery for triangular fibrocartilage complex (TFCC) are scarce. Surgeons and patients would benefit from self-reported outcome data on pain, function, complications, and satisfaction after this surgery to enhance shared decision-making. The aim of this study is to determine the long-term outcome of adults who had open surgery for the TFCC. A prospective cohort study that included patients with open surgery for the TFCC between December 2011 and September 2015. In September 2020, we sent these patients an additional follow-up questionnaire, including the Patient-Rated Wrist Evaluation (PRWE), to score satisfaction, complications, pain, and function.Aims

After failed acetabular fractures, total hip arthroplasty (THA) is a challenging procedure and considered the gold standard treatment. The complexity of the procedure depends on the fracture pattern and the initial fracture management. This study’s primary aim was to evaluate patient-reported outcome measures (PROMs) for patients who underwent delayed uncemented acetabular THA after acetabular fractures. The secondary aims were to assess the radiological outcome and the incidence of the associated complications in those patients. A total of 40 patients underwent cementless acetabular THA following failed treatment of acetabular fractures. The postoperative clinical and radiological outcomes were evaluated for all the cohort.Aims

There is conflicting evidence about the functional
outcome and rate of satisfaction of super-elderly patients (≥ 80 years
of age) after carpal tunnel decompression. We compiled outcome data for 756 patients who underwent a carpal
tunnel decompression over an eight-year study period, 97 of whom
were super-elderly, and 659 patients who formed a younger control
group (<
80 years old). There was no significant difference between
the super-elderly patients and the younger control group in terms

Objectives. The surgical challenge with severe hindfoot injuries is one of technical feasibility, and whether the limb can be salvaged. There is an additional question of whether these injuries should be managed with limb salvage, or whether patients would achieve a greater quality of life with a transtibial amputation.

Bone marrow-derived mesenchymal stem cells obtained from bone marrow aspirate concentrate (BMAC) with platelet-rich plasma (PRP), has been used as an adjuvant to hip decompression. Early results have shown promise for hip preservation in patients with osteonecrosis (ON) of the femoral head. The purpose of the current study is to examine the mid-term outcome of this treatment in patients with precollapse corticosteroid-induced ON of the femoral head. In all, 22 patients (35 hips; 11 males and 11 females) with precollapse corticosteroid-induced ON of the femoral head underwent hip decompression combined with BMAC and PRP. Mean age and BMI were 43 years (SD 12) and 31 kg/m² (SD 6), respectively, at the time of surgery. Survivorship free from femoral head collapse and total hip arthroplasty (THA) and risk factors for progression were evaluated at minimum five-years of clinical follow-up with a mean follow-up of seven years (5 to 8).Aims

Long-term outcomes following the use of human dermal allografts in the treatment of symptomatic irreparable rotator cuff tears are not known. The aim of this study was to evaluate these outcomes, and to investigate whether this would be a good form of treatment in young patients in whom a reverse shoulder arthroplasty should ideally be avoided. This prospective study included 47 shoulders in 45 patients who underwent an open reconstruction of the rotator cuff using an interposition GraftJacket allograft to bridge irreparable cuff tears, between January 2007 and November 2011. The Oxford Shoulder Score (OSS), pain score, and range of motion (ROM) were recorded preoperatively and at one year and a mean of 9.1 years (7.0 to 12.5) postoperatively.Aims

One-stage exchange for periprosthetic joint infection (PJI) in total hip arthroplasty (THA) is gaining popularity. The outcome for a repeat one-stage revision THA after a failed one-stage exchange for infection remains unknown. The aim of this study was to report the infection-free and all-cause revision-free survival of repeat one-stage exchange, and to investigate the association between the Musculoskeletal Infection Society (MSIS) staging system and further infection-related failure. We retrospectively reviewed all repeat one-stage revision THAs performed after failed one-stage exchange THA for infection between January 2008 and December 2016. The final cohort included 32 patients. The mean follow-up after repeat one-stage exchange was 5.3 years (1.2 to 13.0). The patients with a further infection-related failure and/or all-cause revision were reported, and Kaplan-Meier survival for these endpoints determined. Patients were categorized according to the MSIS system, and its association with further infection was analyzed.Aims
