Unicompartmental knee replacement provides excellent results at 15 years .
OrthoEvidence Journal (OE Journal) - ACE Report
OE Journal. 2013;1(4):6 J Bone Joint Surg Br. 2009 Jan;91(1):52-7To compare the two surgical procedures, 102 knees requiring knee replacement were randomized to receive either unicompartmental knee replacement (UKR) or total knee replacement (TKR). A previous assessment established that UKR had superior results at 5 year follow-up. The continued 15 year follow-up demonstrated that results were maintained with 71.4% of patients having excellent outcomes in terms of Bristol knee score and prosthesis survivorship.
Was the allocation sequence adequately generated?
Was allocation adequately concealed?
Blinding Treatment Providers: Was knowledge of the allocated interventions adequately prevented?
Blinding Outcome Assessors: Was knowledge of the allocated interventions adequately prevented?
Blinding Patients: Was knowledge of the allocated interventions adequately prevented?
Was loss to follow-up (missing outcome data) infrequent?
Are reports of the study free of suggestion of selective outcome reporting?
Were outcomes objective, patient-important and assessed in a manner to limit bias (ie. duplicate assessors, Independent assessors)?
Was the sample size sufficiently large to assure a balance of prognosis and sufficiently large number of outcome events?
Was investigator expertise/experience with both treatment and control techniques likely the same (ie.were criteria for surgeon participation/expertise provided)?

O Índice de Fragilidade é uma ferramenta que auxilia na interpretação de achados significativos, fornecendo uma medida de força para um resultado. O Índice de Fragilidade representa o número de eventos consecutivos que precisam de ser adicionados a um resultado dicotómico para que o resultado deixe de ser significativo. Um número pequeno representa um resultado mais fraco e um número grande representa um resultado mais forte.
Porque é que este estudo era necessário agora?
Unicompartmental knee replacement (UKR) has increased in popularity over the last few years; however, there is still an existent belief that a TKR is preferable for patients over the age of 60, as is regarded to have a better success rate. The data in this study has previously established the superiority of UKR with a follow up of 5 years. For a longer term follow up of 15 years, this study was conducted to validate the findings.
Qual era a principal questão de investigação?
Does the use of the St Georg Sled unicompartmental knee replacement provide superior outcomes when compared to total knee replacement at 15 years?
- Surgeries in 4 patients in the UKR group were unsuccessful (either revision surgery or a Bristol knee score < 60), whereas in 6 patients in the TKR group were considered unsuccessful (p=0.51) .
- 71.4% of patients had an excellent outcome in the UKR group compared to 52.6 % in the TKR.
- Average Bristol knee scores were 92 and 87.5 in the UKR and TKR groups, respectively (p=0.99), with the median pain scores being 40 and 35 (15-90), respectively.
- The survivorship of the implant (either revision surgery or a Bristol knee score < 60) was 89.8% (95% CI 74.3 to 100) in the UKR group and 78.7% (95% Ci 56.2 to 100) in the TKR group. There was no difference in survival between the two groups (p=0.51).
- 78% patients in the UKR group had > 120° of flexion compared to 38% in the TKR group (p=0.08).
De que é que me devo lembrar mais?
Unicompartmental knee replacement maintained the excellent early results at 15 years, demonstrating excellent Bristol knee scores and implant survivorship.
Como é que isto afectará o tratamento dos meus doentes?
The use of UKR can provide excellent results for elderly patients requiring knee replacement. Further research is needed with larger simple sizes.
