Background: Total shoulder arthroplasty (TSA) is commonly performed for arthritic conditions of the shoulder. The outcome after TSA is generally good, but there are several modes of failure, with one of the more common reasons being glenoid loosening. One possible cause for glenoid loosening is inadequate cementation technique. The purpose of this study was to evaluate the incidence of lucent lines on the first postoperative radiograph using 2 different cementation techniques.
Materials And Methods: One hundred consecutive patients had a pegged glenoid placed with 1 of 2 different cementation techniques. In 26 consecutive patients, the pegged glenoid component was cemented with a traditional minimal manual pressurization technique, whereas 74 underwent a contemporary 3-step pressurization cementation technique before implant insertion. The first postoperative radiograph was evaluated using the system of Lazarus et al, looking at the frequency of lucent lines. The radiographs were deidentified and were randomized and evaluated by 2 independent observers on 3 separate occasions.
Results: The Kruskal-Wallis test showed significant differences between grades of radiolucent lines for pressurized versus unpressurized cementation techniques. There were significantly (P < .05) fewer lucent lines identified in the group that underwent contemporary 3-step pressurization as opposed to the group that underwent minimal manual pressurization. Intraobserver reliability and interobserver reliability with Cronbach α coefficients were good.
Conclusion: The 3-step pressurized cementation technique resulted in a low incidence of radiolucent lines around the glenoid implant in patients undergoing TSA.

Mid-term outcomes after primary total hip arthroplasty with a cemented short stem in an elderly patient cohort.
Arch Orthop Trauma Surg
December 2024
Department of Orthopedics and Trauma Surgery, Ospedale Civile Maggiore Di Borgo Trento, University of Verona, Piazzale Aristide Stefani, 1, 37126, Verona, VR, Italy.
Purpose: The main objective of this prospective study was to assess clinical, radiographic and safety mid-term outcomes after THA with a short cemented stem in an elderly patient cohort. Moreover, the study aimed at investigating the mid-term survivorship of the implant and the incidence of complications.
Methods: 96 consecutive patients (100 cases) underwent THA with a short cemented stem.
Mid-term radiographic evaluation of a monoblock trabecular metal tibia following total knee arthroplasty in obese and morbidly obese patients.

Henry Community Health, 2200 Forest Ridge Parkway, New Castle, IN47362, USA.
Background: Indications for primary total knee arthroplasty (TKA) have become more inclusive of morbidly obese patients, however, higher rates of complications and lower implant survival have also been reported in this population. The purpose of this study was to investigate the mid-term survival, clinical, and radiographic outcomes of a cementless trabecular metal monoblock tibial component in severely obese patients.
Methods: This was a retrospective study of class II and III obese (BMI > 35) patients who received a cementless primary TKA.
Survivorship and Functional Outcomes After Complex Primary Total Knee Arthroplasty With Contemporary Rotating-Hinge Implants.
HSS J
September 2024
Department of Orthopedic Surgery, Hospital for Special Surgery, New York, NY, USA.
Article Synopsis
- Initial hinge designs for total knee arthroplasty had issues with loosening, but this study focuses on contemporary rotating-hinge implants.
- A retrospective review of 54 surgeries from 2014 to 2018 showed promising outcomes, with a patient demographic mostly of older women dealing with severe knee instability.
- Results indicated a 95% reoperation-free survival rate at 2 and 5 years, significant improvements in patient-reported quality of life, and no signs of aseptic loosening on follow-up imaging.
Uncemented reverse total shoulder arthroplasty: is it a safe option for elderly patients with proximal humerus fractures?
Int Orthop
January 2025
Department of Orthopaedic Surgery and Traumatology, Cantonal Hospital Thurgau, Pfaffenholzstrasse 4, 8501, Frauenfeld, Switzerland.
Purpose: Reverse shoulder arthroplasty (RSA) is a common surgical procedure for elderly patients with proximal humerus fractures. Cement fixation of the humeral stem is considered the gold standard for this procedure. Due to the high prevalence of osteoporosis in this patient population, the risk of intraoperative fractures is increased when uncemented stems are used.

Article Synopsis
- A study was conducted on ceramic-on-metal hip replacements originally performed from 2007 to 2009 to assess their long-term outcomes after 5.8 and 10.1 years.
- The revision rates increased from 3.1% at six years to 8.8% at ten years, with a notable rise in pain scores and decline in overall hip function during that time.
- The findings revealed significant issues like increased radiolucent lines in X-rays and higher metal ion levels, indicating that the survival rate for these implants dropped to 91.2%, below the recommended threshold, raising concerns for future implant designs.
