Comparison of clinical outcomes between knotted and knotless double-row arthroscopic rotator cuff repairs: a meta-analysis.

Background: The ideal rotator cuff repair technique should allow for a quick and simple arthroscopic application which provides both adequate biomechanical stability and an appropriate biological state with the intention of promoting eventual healing of tendon to bone. While the biomechanical superiority of double-row repairs including higher repair strength, reduced gap formation, and wider footprint restoration have been proven, controversy remains regarding the clinical benefits of knotless compared with knot tying techniques. Our study aims to review the available evidence in the literature comparing the clinical outcomes between knotted and knotless transosseous double-row rotator cuff repair techniques.

Rotator Cuff Repairs With and Without Acromioplasties Yield Similar Clinical Outcomes: A Meta-analysis and Systematic Review.

Purpose: This meta-analysis reviews the current literature comparing the patient-reported outcome measures of patients who underwent rotator cuff repairs with and without acromioplasties.

Method: A comprehensive literature search was performed using PubMed, EMBASE, and Scopus databases, obtaining 1,456 studies for the review. After the filtering process, 8 studies remained for our meta-analysis, of which 7 were prospective trials.

Autologous collagen-induced chondrogenesis versus microfracture for chondral defects of the knee: Surgical technique and 2-year comparison outcome study.

Objective: Osteochondral lesions of the knee affect patients from all age groups with arthroscopic microfracture being the current gold standard of treatment of such lesions. Autologous collagen-induced chondrogenesis (ACIC) is a novel procedure that has recently been gaining popularity. This study aims to compare the 6 and 24 month post-operative outcomes between patients undergoing microfracture only and microfracture with ACIC.

Predictive value of common serum glycaemic markers on periprosthetic joint infection following Total Joint Arthroplasty: A review of the literature.

It is well established that diabetes mellitus and osteoarthritis commonly exist together and among various treatment modalities for osteoarthritis, Total Joint Arthroplasty (TJA) has been effective. Prosthetic Joint Infection (PJI) is a serious complication of TJA with high costs and morbidity associated with it. The aim of this study is to provide background information and relevance of diabetes on PJI, and to conduct a review on existing literature, to find out if common serum glycaemic markers in diabetes could be used as predictors for PJI after TJA.

The rule of twos: Technical note on consistent anatomical landmarks for hamstring graft harvesting.

We describe a novel hamstring harvesting technique using the "Rule of Twos" as an aide-memoire to dissect the conjoint tendon in an Asian population undergoing anterior cruciate ligament reconstruction. In a prospective study performed on 17 patients to validate this technique, a 2cm incision is placed 2cm distal and medial to the tip of the tibial tubercle. The surgeon then measured the following variables and calculated their means: 1) Distance from the tip of the tibial tuberosity to the proximal edge of the conjoint tendon (19.

Patterns of Weight Change and Their Effects on Clinical Outcomes Following Total Knee Arthroplasty in an Asian Population.

Background: This prospective cohort study was designed to evaluate weight change patterns and their effects on clinical outcomes following total knee arthroplasty (TKA) in the Asian population. We hypothesized that Asian patients will have a different pattern of weight change following TKA compared to Western patients and that weight loss following TKA will be associated with better clinical outcomes.

Methods: A cohort of consecutive patients who underwent TKA from 2004 to 2015 was included.

Which Patients Require a Contralateral Total Knee Arthroplasty Within 5 Years of Index Surgery?

Osteoarthritis (OA) of the knee often presents bilaterally. However, not all patients with severe bilateral knee OA require bilateral total knee arthroplasty (TKA). This study aims to identify predictive factors for contralateral TKA in patients presenting with severe bilateral knee OA undergoing unilateral TKA.

Achieving Minimum Clinically Important Difference in Oxford Knee Score and Short Form-36 Physical Component Summary Is Less Likely with Single-Radius Compared with Multiradius Total Knee Arthroplasty in Asians.

Single-radius (SR) and multiradius (MR) total knee arthroplasties (TKAs) have produced similar outcomes, albeit most studies originate from Western nations. There are known knee kinematic differences between Western and Asian patients after TKA. The aim of this study is to compare the short-term patient-reported outcome measures (PROMs) of SR-TKA versus MR-TKA in Asians.

Obesity is associated with poorer range of motion and Tegner scores following hamstring autograft anterior cruciate ligament reconstruction in Asians.

Background: Current literature reporting on the impact of BMI on outcomes of orthopaedic surgical procedures is varied and inconsistent. The purpose of our study was to evaluate if body mass index (BMI) affects outcomes of primary anterior cruciate ligament reconstruction (ACLR) in an Asian population.

Methods: We retrospectively reviewed prospectively collected data of 141 consecutive patients who underwent primary ACLR by a single surgeon, the senior author of this study.

Prevalence of Venous Thromboembolic Events Is Low in Asians After Total Knee Arthroplasty Without Chemoprophylaxis.

Background: This retrospective cohort study was designed to establish the prevalence of clinically significant venous thromboembolic events (VTE) in our patients undergoing total knee arthroplasty (TKA) without chemoprophylaxis.

Methods: A single-surgeon cohort of patients who underwent TKA from 2006 to 2014 were included. All patients had a pneumatic tourniquet applied and a drain inserted postoperatively.

Injury patterns in patients presenting with a recurrent anterior cruciate ligament tear following primary reconstruction.

Background: An anterior cruciate ligament (ACL) graft rupture or a primary ACL injury in the contralateral knee is one of the greatest concerns of patients following primary anterior cruciate ligament reconstruction (ACLR). Our study describes the epidemiology and presence of concomitant meniscal injuries of patients with a graft rupture following primary ACLR or a primary rupture of the contralateral ACL following primary ACLR of the ipsilateral knee.

Methods: We reviewed the medical records of 42 patients who underwent a second ACLR.

Routine pre-operative group cross-matching in total knee arthroplasty: A review of this practice in an Asian population.

Background: Routine pre-operative group cross-match (GXM) and post-operative haemoglobin level measurements are performed for all total knee arthroplasty (TKA) patients in many institutions. We aimed to determine whether this practice is justified, and to identify predictors for post-operative transfusion.

Materials And Methods: A retrospective review was performed on 226 TKA procedures performed between Jan.

Diagnosis of ligamentous and meniscal pathologies in patients with anterior cruciate ligament injury: comparison of magnetic resonance imaging and arthroscopic findings.

Background: Magnetic resonance imaging (MRI) is routinely used to diagnose or support clinical diagnoses for meniscal or ligamentous injuries prior to offering patients arthroscopic treatment. However, the sensitivity of MRI for the detection of meniscal injury is not yet 100%. Sportsmen have occasionally returned to play with undiagnosed meniscal lesions on the basis of a normal MRI examination.

Outcomes are favorable in Asian patients undergoing deltoid-on open rotator cuff repair without acromioplasty.

Background: To evaluate if rotator cuff repair without acromioplasty would result in improvement in outcomes without the risks associated with acromioplasty in Asian patients.

Methods: 38 primary repairs of tears of the rotator cuff were performed through a deltoid-on approach. The Simple Shoulder Test (SST) and UCLA shoulder rating scale were measured preoperatively and at 2 years post-operatively.

Irreducible dislocation of the great toe interphalangeal joint secondary to an incarcerated sesamoid.

Irreducible dorsal dislocation of the interphalangeal (IP) joint of the great toe is rare. We report a case of a 29-year-old gentleman who presented to the Orthopaedic Surgery Specialist Outpatient Clinic with an irreducible IP joint of the great toe that had been untreated for 4 weeks. The mechanism of injury is believed to be a combination of axial loading with a hyperdorsiflexion force when the patient fell foot first into a drain.

Postoperative range of motion does not correlate with patient reported outcome scores in Asians after total knee arthroplasty.

Activities in Asian cultures require greater knee flexion. However, this study hypothesized that post-operative range of motion (ROM) does not correlate with patient reported outcome scores at 2years. 292 TKAs were evaluated at a public hospital in Singapore from January 2006 to May 2009.

Total knee arthroplasty in Asian subjects: preoperative range of motion determines postoperative range of motion?

Objective: To evaluate whether preoperative range of motion is a key determinant of postoperative range of motion in Asian patients undergoing conventional total knee arthroplasty.

Methods: A retrospective review of 302 patients who underwent primary total knee arthroplasty performed by a single surgeon was conducted. Patients who had a fixed flexion deformity of ≥15° were excluded.

The use of pneumatic tourniquets is safe in Asians undergoing total knee arthroplasty without anticoagulation.

Background: There has always been controversy surrounding the use of pneumatic tourniquets in total knee arthroplasty (TKA) as they have been implicated in venous thromboembolic events (VTE). We aimed to evaluate the incidence of clinically significant VTE in Asians who underwent conventional TKA under tourniquet throughout the duration of surgery, without post-operative chemical VTE prophylaxis, but using post-operative pneumatic compression devices.

Methods: Five hundred and thirty-one patients of a single surgeon who underwent elective total knee arthroplasty were retrospectively reviewed.
