Chondrolysis of the glenohumeral joint
A study in the Journal of Bone & Joint Surgery—American (JBJS-A) (April 6) examines factors that might be associated with glenohumeral chondrolysis after arthroscopic shoulder surgery. The retrospective cohort study of 375 intra-articular shoulder arthroscopic surgical procedures performed by a single orthopaedic surgeon found a correlation between the occurrence of chondrolysis and the intra-articular infusion of a local anesthetic—either bupivacaine or lidocaine—after surgery. The risk of chondrolysis was greater for patients with one or more suture anchors placed in the glenoid, for younger patients, and for those who had the surgery near the end of the 10-year study period.

Outcomes similar for ACDF or CDA
An analysis of three randomized, prospective trials comparing cervical disk arthroplasty (CDA) with anterior cervical diskectomy and fusion (ACDF) finds that both methods produce good results at 2-year follow-up, but CDA was associated with lower rates of repeat surgery. The three trials covered 1,213 total patients and three different CDA products. Overall, 621 patients received CDA and 592 patients underwent ACDF.
