Study on Personalized Total Knee Arthroplasty (TKA) Rehabilitation Using Telemedicine and Psychoeducation

The aim of this clinical study is to evaluate the effectiveness of a telemedicine approach in improving treatment adherence and functional outcomes in patients recently underwent total knee replacement for primary osteoarthritis. The study focuses on patients aged between 50 and 75 years, with a BMI below 35, and without known oncological or neurological conditions. Participants will receive a personalized rehabilitation program, including initial assessment, psychomotivational framing, and rehabilitation interventions based on telemedicine. The goal is to provide a framework for adopting more detailed and personalized rehabilitative strategies.The main research questions are:• Primary: pain reduction (VAS), physical function (WOMAC, KOOS).• Secondary: activities of daily living (Barthel index, mRS); psychobehavioral assessments (CEQ, PAM13, CG-PAM, COP-NIV); attitude towards technology (TAM); use of analgesics and walking aids.Sample size is estimated at 40 patients (20 per group), accounting for a 20% dropout rate, divided into:• Control group: standard outpatient rehabilitation with a personalized exercise program.• Study group: standard outpatient rehabilitation with a personalized exercise program plus telemonitoring via video calls. Procedures:• Recruitment and signing of informed consent; • Initial assessment (demographic data, baseline tests) and start of post-acute rehabilitation during hospitalization at T0;• Outpatient rehabilitation interventions with/without tele-rehabilitation support (twice weekly) at discharge, with follow-up assessments at T1 (1.5 months) and T2 (3 months);• Weekly recording of analgesic consumption through a dedicated diary;• Recording the date of discontinuation of walking aids.

The Importance of Different Modularity of the Polyethylene Insert for Tibial Component Migration and Adaptive Bone Remodeling After Uncemented Total Knee Arthroplasty Using Trabecular Metal Technology (TMT) Zimmer NexGen®, (Monoblock vs. Modular Design)

In a prospective randomised study two uncemented tibial components with different polyethylene modularities (Trabecular Metal Technology (TMT) Zimmer NexGen® monobloc and TMT Zimmer NexGen® modular) used for total knee arthroplasty (TKA) is evaluated. Both tibial component coatings are designed to provide excellent condition for bone ingrowth. The differences between the two tibial components are evaluated by measurements of migration of the tibial component assessed by Radiostereometric analysis (RSA) and measurements of the adaptive bone remodeling of the proximal tibial assessed by dual energy X-ray absorptiometry (DEXA).
