Comparative StudyFracture characteristics and functional outcomes for Schatzker V/VI bicondylar tibial plateau fractures with a separate tubercle fragment: a comparative study.
A separate tibial tubercle fragment (TF) is found in up to half of all bicondylar tibial plateau (BTP) fractures. Adequate healing of the TF is required to reconstitute the extensor mechanism of the knee. The purpose of this study was to compare outcomes after surgical fixation of BTP fractures with and without a TF. ⋯ In this comparative study, the presence of a TF did not portend a worse functional outcome for patients with a healed fracture. Rates of open fracture and high energy mechanism of injury were significantly higher in the TF group.. Surgeons should be aware that a separate TF may indicate a more severe injury. More studies are needed to determine whether the presence of a TF is associated with higher complication rates.

Introducing the forearm fracture index to define the diametaphyseal junction zone through clinical evaluation in a cohort of 366 diametaphyseal radius fractures.
Unstable diametaphyseal radius fractures (DMRFs) can be prone to complications, and treatment strategies are heterogeneous. Studies are difficult to interpret as definitions of the diametaphyseal junction zone (DMJZ) are impractical for clinical use, imprecise, or prone to error. ⋯ Study of Diagnostic Test, Level II.

Robotic-assistance is associated with better joint outcomes compared to conventional techniques in surgically routine total hip arthroplasty: a propensity-matched large database study of 3948 patients.
The outcomes of total hip arthroplasty (THA) are highly dependent upon the restoration of native hip biomechanics and optimal component positioning. Robotic technologies for THA have rapidly improved the accuracy of component positioning and maintaining the planned center of rotation. While robotic-assisted THA (RA-THA) has primarily been employed in surgically intricate cases, its potential benefits in scenarios of diminished surgical complexity remain less explored. Therefore, the purpose of this study was to assess the odds of developing systemic and joint complications following RA-THA in cases of reduced surgical complexity. ⋯ These findings suggest that RA-THA has comparable systemic and less joint complication risks at 30-day to 5-year timepoints between RA-THA and C-THA. Future studies with large sample sizes and long-term follow-up are needed to understand the patient-reported outcomes and functional outcomes of RA-THA for cases with reduced surgical complexity.

A modified suture technique using polydioxanone (PDS II) for capsule closure in total knee arthroplasty: a prospective randomized study compared with traditional suture technique.
To describe and evaluate the modified suture technique using PDS II for capsule closure in Total knee arthroplasty. ⋯ The modified suture technique using PDS II appears to be a promising option for the capsule closure in TKA because it was associated with shorter surgical time, better water tightness, fewer wound see-page, shorter of hospitalization and relatively fewer complications.

Stair climbing ability and postoperative activity in patient-reported outcomes after CR-TKA are more related to handgrip strength than sagittal knee stability.
Stair ascent and descent are physically demanding tasks requiring higher functional ability of the lower extremity muscles and joint range of motion than level walking, and are associated with patient satisfaction after total knee arthroplasty (TKA). This study aimed to investigate stair ascent and descent ability after cruciate-retaining (CR)-TKA using the patient-reported outcomes, and to examine the role of knee sagittal stability and handgrip strength in postoperative stair ascent and descent ability. ⋯ Handgrip strength was associated with stair ascent and descent ability and postoperative activity in the patient-reported outcomes, rather than CR-TKA knee sagittal stability.
