UKA is a viable option for treating unicompartmental knee osteoarthritis. With the proper indications and an accurate technique UKA may be indicated also in very elderly patients with reduced complications and morbidity, and excellent survivorship.

The purpose of this study was to report early complications for anatomic total shoulder arthroplasty (aTSA) performed for instability arthropathy after a prior coracoid transfer procedure and compare them with those of a control group of patients following aTSA for primary osteoarthritis. A retrospective review was performed of 14 patients after aTSA with a prior coracoid transfer procedure. A control group of 42 patients with an aTSA for primary osteoarthritis were matched 3:1 according to age, sex, body mass index, comorbidities, and dominant shoulder. Chart reviews identified any complications within 1 year, in addition to blood loss and operative time in both groups. Preoperative computed tomography scans were used to determine Walch glenoid classification and Goutallier classification of the subscapularis. The mean operative time was not significantly different between the coracoid transfer cohort and the control group, and the mean estimated blood loss was only 6.9 mL greater in the coracoid transfer group. The coracoid transfer group had 2 (14.3%) patients with complications, with 1 early revision for an acute deep infection. The control group had 4 (9.5%) complications in 3 (7.1%) patients, with no early revisions. There was no statistical difference in complications between the groups ( P =.618). Anatomic TSA for instability arthropathy after coracoid transfer had similar operative time, blood loss, and 1-year complication rates as those of the control group. These results provide some evidence to support the continued use of aTSA in select patients with instability arthropathy after prior coracoid transfer procedure.

ObjectivesBursitis of the olecranon and the patella are not rare disorders, and conservative management is successful in most cases. However, when patients do not respond to conservative treatment, open excisional surgery or, recently, endoscopic bursectomy, can be used. The aim of this study was to evaluate the results of open and endoscopic treatments of olecranon and prepatellar bursitis.Patients and methodsForty-nine patients (37 male and 12 female), who were treated with endoscopic bursectomy (25 patients) or open bursectomy (24 patients) were included in this study. Thirty patients had olecranon bursitis, while 19 patients had prepatellar bursitis. The patients’ average age was 61.1 ± 12.3 (range 33-81) years. All of the patients’ hospitalization and surgery times were recorded.The satisfaction of the patients was evaluated with a satisfaction scoring system, as well as by evaluating residual pain, the range of joint movement, and the cosmetic results of the procedure.ResultsThe average follow-up time was 16 ± 9 months (range 12–27). The median operation time was 23.2 ± 3.5 minutes for the endoscopic bursectomy group and 26.4 ± 6.8 minutes for the open bursectomy group. The median hospitalization time was 0.56 ± 0.5 days (range 0-1 day) for the endoscopic group and 1 ± 0 days for the open bursectomy group (P<0.01).According to the patient satisfaction questionnaire, the endoscopic bursectomy group’s score was 8.5 ± 1.3 (range 5-10), and the open bursectomy group’s score was 5.29 ± 1.8 (range 1-9) (P<0.01).ConclusionEndoscopic bursectomy is a time-saving and efficient surgical treatment option for patients with prepatellar and olecranon bursitis.

The main finding of the present in vivo study was the possibility to determine significant effects on post-operative static laxity level of different surgical variables of ACL reconstruction. In particular, the present study defined the conditions that minimize the different aspects of post-operative laxity at time-zero after surgery.

Aim: The aim of this study was to derive a pure, unbiased, reliable and accurate objective relationship between the local knee axis measurements through a short knee anteroposterior roentgenogram and the lower limb axis measurement through an orthoroentgenogram. Patients and Methods: Radiographs of 114 patients (114 knees) were evaluated by two independent raters for measurement of lower limb axis on an orthoroentgenogram and the local knee axis on short knee anteroposterior X-ray, which was derived by cropping the orthoroentgenogram by a blinded radiology assistant. The raters measured at two different time-points separated by an interval of 30-day period. Intra-rater and inter-rater reliabilities were calculated by intra-class correlation coefficients and three models were built to establish the relationships of X-ray anatomical axis with orthoroentgenogram anatomical axis, orthoroentgenogram anatomical axis with orthoroentgenogram mechanical axis and X-ray anatomical axis with orthoroentgenogram mechanical axis. Results: For three different measurements, intra-class correlation coefficients of Rater 2 were higher than 0.90 which shows perfect reliability, while that for Rater 1 was low. Furthermore, first measurements were more consistent than the second measurement. There was a strong positive correlation in all the three models except for varus cases in the last. Conclusion: The standardized correlation derived between the two different techniques for measuring knee alignment is fairly comparable with the studies in the past and would serve as a reliable template for future studies concerning relationships between the two, in addition to helping knee surgeons make more reliable and accurate interpretations through local knee axis measurements.
