Randomized Controlled Trial Comparative StudyNo difference in early functional outcomes for mini-midvastus and limited medial parapatellar approaches in navigation-assisted total knee arthroplasty: a prospective randomized clinical trial.
Patients desire less pain and faster recovery of range of knee motion after total knee arthroplasty (TKA). While minimal invasive surgery (MIS) TKA appears to meet these needs, concerns exist regarding component malpositioning. Navigation systems can reduce the incidence of component misalignment. ⋯ There were also no differences between groups in terms of total blood loss, approach preferred by patients, and radiographic component positioning. The present study found that navigation-assisted MMV and navigation-assisted LMPP resulted in similar outcomes in terms of pain, ROM, HSS score, and radiologic outcomes over the first six postoperative months. We recommend the LMPP approach over the MMV approach in navigation-assisted MIS TKA because it is more familiar to surgeons and is easier to convert to the conventional approach where necessary.

Randomized Controlled TrialEffects of periarticular steroid injection on knee function and the inflammatory response following Unicondylar Knee Arthroplasty.
There is little information on the values of CRP and ESR as markers for inflammation in Unicondylar Knee Arthroplasty. The effect of periarticular steroid injection in post-operative pain relief and clinical recovery has not been well studied. Eighty-three consecutive patients undergoing primary UKAs were randomized to receive either an intra-operative periarticular injection with a local anaesthetic and adrenaline or with the addition of triamcinolone acetonide. ⋯ Patients were assessed daily till discharge and up to 6 months post-operatively. Plasma CRP and ESR fluctuate after a UKA, with normalizing values indicating uneventful recovery. Periarticular steroid injections reduce post-operative pain and inflammation, and are clinically relevant as they improve short-term functional recovery and clinical parameters, resulting in better outcomes for patients without having major complications.
