Pain control after arthroplasty has been a key concern for orthopedic surgeons. After total knee arthroplasty (TKA), a small group of patients developed a painful joint with suboptimal range of motion. Manipulation under anesthesia increases flexion and extension while decreasing pain in most cases. ⋯ Group A had an incidence of manipulation of 4.75% (37/778). Of 357 patients, 8 required manipulation in group B, which is an incidence of 2.24%. We recommend that orthopedic surgeons consider using a multimodal pain management protocol for TKA.

Total joint arthroplasty is a safe and successful procedure. However, numerous complications may present after elective arthroplasty. This study prospectively collected data on systemic and local in hospital complications after 15383 joint arthroplasties, which included 8230 total hip arthroplasties and 7153 total knee arthroplasties. ⋯ There were 109 major local complications, including 16 vascular injuries, 29 peripheral nerve injuries, 25 periprosthetic fractures, and 18 dislocations. Total joint arthroplasty, despite its success, can be associated with rare serious and life-threatening complications. This study provides a baseline of complications that can occur after elective joint arthroplasty.

Randomized Controlled Trial
Multimodal analgesia without parenteral narcotics for total knee arthroplasty.
Use of parenteral narcotics after total knee arthroplasty is considered by most orthopedic surgeons to be the standard of care. This study tested the hypothesis that a multimodal oral pain medication protocol could control pain and minimize complications of parenteral narcotics. ⋯ The average daily pain score was less than 4 out of 10, nausea occurred in 15 patients (21%), emesis in 1 patient (1.4%), and there were no severe complications. This study proved the hypothesis that pain after total knee arthroplasty could be effectively managed without routine use of parenteral opioids.

Case Reports
Involvement of the lateral femoral cutaneous nerve as source of persistent pain after total hip arthroplasty.
This report describes a situation in which the lateral femoral cutaneous (LFC) nerve was the source of incisional pain in a patient after a total hip arthroplasty. The painful scar was denervated by an approach that resected just the posterior branch of the LFC nerve. ⋯ One of the 3 patients reported here had a coexisting meralgia paresthetica that was treated by the same operative approach. The orthopedic surgeon should include the LFC nerve as an origin of persistent pain after total hip arthroplasty.

Our purpose was to estimate the incidence of unicompartmental knee arthroplasty in the United States. Three major implant manufacturers provided data over an 8-year period from 1998 to 2005. ⋯ Unicompartmental knee arthroplasty increased at an average rate of 32.5% during the study period compared with a 9.4% average increase in rate of total knee arthroplasty over the same period. Although unicompartmental arthroplasty is growing at triple the rate of total knee arthroplasty in the United States, the data suggest that unicompartmental implants currently account for less than 8% of all knee arthroplasty procedures.
