Stemless anatomic TSA result ed in similar functional outcomes and complication rates to stemmed TSA with decreased operative time and lower blood loss .
BACKGROUND Stemless anatomic total shoulder arthroplasty ( TSA ) is used in the treatment of osteoarthritis of the shoulder joint and other degenerative shoulder diseases .
It has several proposed advantages over stemmed TSA including increased bone preservation , decreased operative time , and easier removal at revision .
Higher preoperative sensitivity to pain and pain at rest are associated with worse functional outcome after stemless total shoulder arthroplasty: A PROSPECTIVE COHORT STUDY
Aims The aims of this study were to investigate any possible relationship between a preoperative sensitivity to pain and the degree of pain at rest and on exertion with postoperative function in patients who underwent stemless total shoulder arthroplasty ( TSA ) . Patients and Methods In this prospect i ve study , we included 63 patients who underwent stemless TSA and were available for evaluation one year postoperatively . There were 31 women and 32 men ; their mean age was 71 years ( 53 to 89 ) . The pain threshold , which was measured using a Pain Matcher ( PM ) unit , the  degree of pain ( visual analogue scale at rest and on exertion , and function using the short version of the Disabilities of the Arm , Shoulder and H and question naire ( QuickDASH ) , were recorded preoperatively , as well as three and 12 months postoperatively . Results We found an inverse relationship between both the preoperative PM threshold and pain ( VAS ) at rest and the 12‐month postoperative QuickDASH score ( Pearson correlation coefficient ( r ) ≥ 0.4 , p < 0.05 ) . A linear regression analysis showed that the preoperative PM threshold on the affected side and preoperative pain ( VAS ) at rest were the only factors associated with the QuickDASH score at 12 months . Conclusion These findings indicate the importance of central sensitization in the restoration of function after TSA . Further studies are required to investigate whether extra analgesia and rehabilitation could influence the outcome in at risk patients
