Osteoarthritis (OA) is a chronic, irreversible degenerative disease of the joint, predominantly affecting the knee, for which the only affective treatment to control the symptomatology is joint replacement surgery. Total knee arthroplasty (TKA) is the most common procedure performed in orthopaedic surgery and increasing effort is being placed in perfectionating the prothesis designs and surgical techniques. The purpose of this study was to compare two medial pivot, ultra-congruent TKA designs, Medacta GMK-Sphere and Zimmer-Biomet Persona Medial Congruent (MC) prothesis, implanted in 36 patients operated in the IRCCS Policlinico San Matteo – Pavia (Italy), between the year 2018 and 2023, from a patient’s perspective. The comparison was performed through Patient Report Outcome Measurements (PROMS), which allowed to assess the level of pain, difficulty and awareness of the artificial joint during everyday life activities. According to the results obtained in this study, both implants have achieved great overall result for patient satisfaction and it was not possible to determine the superiority of one design over the other.

L'osteoartrite è una malattia cronica, degenerativa ed irreversibile delle articolazioni, che colpisce prevalentemente il ginocchio, per la quale l’unico trattamento efficace per controllare la sintomatologia è l’impianto di una protesi articolare. L’artroplastica del ginocchio è la procedura più comunemente eseguita nella chirurgia ortopedica per la quale si è sempre alla ricerca di perfezionamento nel design delle protesi e nelle tecniche chirurgiche. Lo scopo di questo studio è stato quello di confrontare due protesi ultra congruenti, a pivot mediale, Medacta GMK-Sphere e Zimmer-Biomet Persona Medial Congruent (MC), impiantate in 36 pazienti operati presso il IRCCS Policlinico San Matteo – Pavia (Italy), tra 2018 e il 2023, dal punto di vista dei pazienti. Il confronto è stato effettuato attraverso i Patient Report Outcome Measurements (PROMS), che hanno permesso di valutare il livello di dolore, difficoltà e consapevolezza dell’articolazione artificiale durante le attività della vita quotidiana. Secondo i risultati ottenuti da questo studio, entrambe le protesi hanno ottenuto ottimi risultati complessivi, e pertanto non è stato possibile determinare la superiorità di un design rispetto all’altro. Nonostante i risultati soddisfacenti, lo studio evidenza difetti in entrambi gli impianti, il che suggerisce la necessità di ulteriori studi per migliorare la funzionalità dell’arto nel post-operatorio.

Abstract
Osteoarthritis (OA) is a chronic, irreversible degenerative disease of the joint, predominantly affecting the knee, for which the only affective treatment to control the symptomatology is joint replacement surgery. Total knee arthroplasty (TKA) is the most common procedure performed in orthopaedic surgery and increasing effort is being placed in perfectionating the prothesis designs and surgical techniques. The purpose of this study was to compare two medial pivot, ultra-congruent TKA designs, Medacta GMK-Sphere and Zimmer-Biomet Persona Medial Congruent (MC) prothesis, implanted in 36 patients operated in the IRCCS Policlinico San Matteo – Pavia (Italy), between the year 2018 and 2023, from a patient’s perspective. The comparison was performed through Patient Report Outcome Measurements (PROMS), which allowed to assess the level of pain, difficulty and awareness of the artificial joint during everyday life activities. According to the results obtained in this study, both implants have achieved great overall result for patient satisfaction and it was not possible to determine the superiority of one design over the other. Despite these satisfactory results, the study evidences flaws in both prothesis designs, which indicates the need of further studies to improve prothesis’s performance.È consentito all'utente scaricare e condividere i documenti disponibili a testo pieno in UNITESI UNIPV nel rispetto della licenza Creative Commons del tipo CC BY NC ND.
