Multicenter Study10-year follow-up of the Columbus knee prostheses system in a prospective multicenter study.
As endpoint of a prospective multicenter 10-year documentation using the Columbus system, this evaluation carried out results of clinical scores (Knee Society Score and Oxford Knee Score), an evaluation of radiological imaging, survival rates and a collection of complication statistics. ⋯ The endpoint analysis after an observation period of 10 years provided good clinical and radiographic results. In particular, an excellent survival rate of 96.6% after 10 years was demonstrated. The data published in this study are the first to be available in a prospective multicenter study on this system, which leads to a high level of clinical significance.

Multicenter Study Observational StudyReverse total shoulder arthroplasty in massive rotator cuff tears: does the Hamada classification predict clinical outcomes?
Reverse total shoulder arthroplasty (RTSA) is a widely recognized treatment to reduce pain and improve shoulder function for patients in various disease stages of cuff tear arthropathy (CTA). However, it remains unclear whether outcomes after RTSA depend on the preoperative stage of CTA. Therefore, this study evaluated whether the Hamada classification influences midterm clinical outcomes after RTSA. ⋯ Inverted bearing RTSA was found to be an effective treatment with similarly good midterm clinical outcomes, similar revision rates, and high implant survival rates in every stage of massive rotator cuff tears. Overall, the preoperative Hamada classification did not influence clinical outcomes or complications after RTSA.

Multicenter StudyComparison of joint awareness after medial unicompartmental knee arthroplasty and high tibial osteotomy: a retrospective multicenter study.
Unicompartmental knee arthroplasty (UKA) and high tibial osteotomy (HTO) are established treatments for medial compartment osteoarthritis (OA) or osteonecrosis (ON) of the knee joint, and the predominance of either procedure is inconclusive. We compared the awareness of the knee after UKA and HTO using the Forgotten joint score-12 (FJS). ⋯ There was no significant difference in FJS between patients who underwent UKA and HTO. Lower BMI, the diagnosis of OA KL grade ≥ 3, and ON were significant predictors of better FJS.

Multicenter StudyIntraoperative damage to surgical gloves during various operations on the musculoskeletal system: a multicenter study.
Various orthopedic surgical procedures cause mechanical stress for gloves. In some cases, sharp-edged objects impact on the glove surfaces. The systematic description of lesions is still missing. ⋯ All investigated interventions led to glove lesions. With increasing mechanical stress, the number of glove defects increased. EN 455 does not account for the intraoperative tear risk. Stricter requirements for gloves should be introduced. Glove change intervals should be defined and implemented, and new materials should be developed.

Multicenter StudyImpact of intra-operative predictive ligament balance on post-operative balance and patient outcome in TKA: a prospective multicenter study.
New technologies exist which may assist surgeons to better predict final intra-operative joint balance. Our objectives were to compare the impact of (1) a predictive digital joint tensioning tool on intra-operative joint balance; and (2) joint balance and flexion joint laxity on patient-reported outcomes. ⋯ Use of a predictive joint tensioning tool improved the final balance in TKA. Improved outcomes were found in balanced knees; however, this improvement did not achieve the MCID, suggesting further studies may be required to define optimal balance targets. Limiting medial and lateral flexion laxity resulted in an increased likelihood of achieving the Patient Acceptable Symptom State for KOOS Pain.
