THA) Or Knee Arthroplasty Research Articles

Timing of arthroplasty, what is the influence of nocturnal pain and pain at rest on the outcome?

The purpose of this study was to investigate whether nocturnal pain and pain at rest preoperatively influence the satisfaction in patients after joint arthroplasty. The second research question is whether subjective outcome (VAS/WOMAC) after hip (THA) or knee arthroplasty (TKA) differs in patients with or without nocturnal pain and pain at rest preoperatively compared to those who do not. A consecutive group of 189 TKAs and 189 THAs was evaluated. The influence of pain at rest and nocturnal pain preoperatively on the outcome was evaluated by means of a one-way ANOVA. Outcome measurements used were WOMAC, VAS pain and VAS Satisfaction. The results show that satisfaction at follow up was not influenced by the presence of nocturnal pain or pain at rest preoperatively. The presence of nocturnal pain and pain at rest preoperatively did result in a poorer WOMAC pain score WOMAC physical impairment score and a higher VAS pain at rest and activity after surgery for both THA and TKA. The results show that the presence of pain at night and pain at rest in symptomatic osteoarthritic patients results in worse VAS and WOMAC scores, but with similar amounts of satisfaction at follow up.

Controlling pain after total hip and knee arthroplasty using a multimodal protocol with local periarticular injections

In this prospective randomized study, patients undergoing total hip (THA) or knee arthroplasty (TKA) were randomized to either a study group receiving periarticular injections or a control group receiving patient-controlled analgesia with or without femoral nerve block (TKA patients). All patients received a comprehensive multimodal perioperative protocol. Pain, recovery of functional milestones, and overall satisfaction were assessed. The THA study group demonstrated significantly lower average pain scores and higher overall satisfaction than the control group. There was no significant difference in pain scores between the study and control groups in the TKA cohort. Both study groups demonstrated lower narcotic usage and side effects as well as improved early functional recovery. Periarticular injection with a multimodal protocol was shown to safely provide excellent pain control and functional recovery and can be substituted for conventional pain control modalities.
