Titanium niobium nitride knee implants are not inferior to chrome cobalt components for primary total knee arthroplasty.
Metal allergy in total knee arthroplasty (TKA) is still a controversial topic. Oxinium, ceramic or titanium niobium nitride (TiNbN) coated implants are available for some knee systems. The hypothesis of this study was that the use of TiNbN-coated components would not lead to inferior results compared to conventional implants and that none of the allergic patients receiving TiNbN-coated implants would require revision for metal allergy. ⋯ The use of titanium niobium nitride-coated implants for primary knee osteoarthritis shows similar clinical and radiological outcomes as conventional TKA without revision for loosening at short- to medium-term follow-up. Level of evidence Level IV study.

Platelet-rich plasma for chronic lateral epicondylitis: Is one injection sufficient?
Chronic lateral epicondylitis is generally treated using nonsurgical methods including physiotherapy and infiltrations of cortisone or platelet-rich plasma (PRP). The latter is known for its simple application as well as associated low risk of adverse events, which lend to its widespread use in treating various musculoskeletal conditions. There is limited evidence on the effectiveness of PRP injections to optimally treat chronic lateral epicondylitis. This study explored the effectiveness of single or repeated injections for patients with symptoms that spanned 6 months or more and were unresponsive to alternate conservative measures. ⋯ Patients with chronic lateral epicondylitis reported significant pain relief and gain in function as well as quality of life 6 months after localized PRP treatment. A single PRP injection may be sufficient.

Multicenter StudyGraft tensioning practices in anterior cruciate ligament reconstruction amongst orthopaedic surgeons in Australia: a national survey.
The application of graft tension during anterior cruciate ligament reconstruction is considered an important feature of ACLR. However, wide variation exists in relation to graft tensioning practice limiting the ability to determine the best approach. Thus, the primary aim of this study was to describe current clinical practice amongst Australian orthopaedic surgeons with respect to graft tensioning and explore influencing factors. ⋯ Tensioning practices appear to consist of three main approaches, (1) manual tension using a sustained maximum one-handed pull, with tension estimated as 41-60 N, applied near full extension, (2) tensioning device, mean tension of 81.85 N, at 30° knee flexion, (3) individual approach based on size and viscoelastic properties of the graft, patient anthropometry, contralateral comparison to the other knee and age of the patient.

Simple shoulder test and Oxford Shoulder Score: Persian translation and cross-cultural validation.
To translate, culturally adapt, and validate the simple shoulder test (SST) and Oxford Shoulder Score (OSS) into Persian language using a cross-sectional and prospective cohort design. ⋯ The PSST and POSS are valid and reliable outcome measures for assessing functional limitations in Persian-speaking patients with shoulder disorders.

Intrarater reliability of goniometry and hand-held dynamometry for shoulder and elbow examinations in female team handball athletes and asymptomatic volunteers.
To evaluate the intrarater reliability for examining active range of motion (ROM) and isometric strength of the shoulder and elbow among asymptomatic female team handball athletes and a control group using a manual goniometer and hand-held dynamometry (HHD). ⋯ It is important to be able to reliably reproduce active ROM and isometric strength evaluations. Using a standardized testing position, goniometry and HHD are reliable instruments in the assessment of shoulder and elbow joint performance testing. We showed good-to-excellent reproducible results for male and female control subjects and female handball athletes, although the single parameters in ROM and strength were different for each group and between the shoulders and elbows.
