Arthroscopic osteocapsular arthroplasty for advanced-stage primary osteoarthritis of the elbow using a computed tomography –based classification

Arthroscopic osteocapsular arthroplasty for stage III osteoarthritis (advanced stage) shows worse clinical and radiologic outcomes compared with stage I or II according to computed tomography (CT) –based classification.

Computed tomography (CT) has been the gold standard for measuring glenoid version in patients with glenohumeral osteoarthritis or instability. However, few studies have compared measurements of glenoid version on magnetic resonance imaging (MRI) versus CT. Clinicians should feel confident in assessing glenoid version on MRI in the absence of CT imaging. In fact, MRI could be comparable to CT even in cases where the entire scapula is not visible on MRI. A 5 ° difference in glenoid version between imaging modalities represents a clinically significant difference.

Abstract Femoroacetabular impingement is a cause of hip pain in young adults as a result of premature dynamic contact between the femur and acetabulum that occurs within the physiological range of hip motion. Diagnosis is made by patient history, clinical examination and radiographic findings. Cross-sectional imaging with computed tomography and magnetic resonance arthrography may be necessary in selected patients. Femoroacetabular impingement can be treated non-operatively with physiotherapist-led conservative care including analgesia and intra-articular steroid injections.

ConclusionsAnatomic ACL reconstruction could restore not only the normal anterior knee laxity, but also the normal tibiofemoral relationship even under an anterior tibial load.

This article outlines the basic science behind the mechanical and inflammatory model of development of PTOA of the ankle. The purpose of this article is to review the state of literature and understanding of ankle PTOA and serve as a foundation for future research aimed at reducing severity and progression of PTOA. Level of Evidence: Diagnostic Level V. See Instructions for Authors for a complete description of levels of evidence.

ConclusionThe ATL was on average 4.3 ° (SD 3.3°) internally rotated relative to the sTEA and 2.1° (SD 3.0°) internally rotated relative to the PCL. The ATL is more externally orientated in varus knees and more internally rotated in valgus knees. The trochlear groove is lateralised by only 2.2 mm when the femoral component is exter nally rotated.Level of evidenceIII.

ConclusionType I lateral hinge fractures encroached either the anterior or posterior cortex of the proximal tibia, but not both. In addition, posterior tibial slope increased over time following surgery in knees with Type I lateral hinge fracture and posterior cortex breakage, suggesting that caution should be exercised when deciding the starting time for weight bearing in such patients.Level of evidenceCase series, Level IV.

AbstractPurposeIt was hypothesized that malrotation of femoral component in total knee arthroplasty (TKA) will significantly impact clinical outcome.MethodsEighty-eight consecutive patients with primary osteoarthritis of the knee were prospectively evaluated. They received a cemented posterior stabilized TKA (NexGen, Zimmer/Biomet® Inc., Warsaw, IN, USA). The femoral component was placed in 3 ° of external rotation referenced to the posterior condylar line. Postoperatively, a CT scan was performed to evaluate rotation of femoral component in the transverse plane. SF-36, KSS, and WOMAC, as well as their range of mot...

ConclusionsAn all-arthroscopic technique for the treatment of combined anterior and posterior glenoid bone loss as a cause of shoulder instability can provide fair to good clinical outcomes, with a low incidence of intra-operative complications. The rate of failure in our series remains higher than that seen in primary stabilization procedures. As such we consider this largely as a salvage procedure for cases in which alternative treatments have failed or are unlikely to succeed.Level of evidenceIV.

Publication date: Available online 25 September 2017 Source:Arthroscopy Techniques Author(s): Graham Tytherleigh-Strong, Lee Van Rensburg Osteoarthritis changes at the sternoclavicular joint (SCJ) have been shown to be present on computed tomography in more than 90% of people over the age of 60 years. Although usually asymptomatic, when symptoms do occur, they can be very debilitating. Most patients respond favorably to conservative treatment, but there is a small cohort of patients who continue to be symptomatic despite adequate conservative treatment. Surgical management with an open SCJ excision has been shown to ...
