Computer-assisted total knee arthroplasty (CAS) remains controversial. Some authors defend that its improvement in knee alignment and positioning positively impacts arthroplasty survival rates, while others have stated that there is minimal or no difference compared to the conventional technique (cTKA). This paper features a retrospective, single-center, single-surgeon study, evaluating CAS surgery vs. regular cTKA in patients who consecutively underwent surgery between 2015 and 2017 (60 CAS patients vs. 59 cTKA). Data collection includes surgery duration, length of stay, blood loss and both preoperative and postoperative clinical outcome evaluation using WOMAC, SF-12, Forgotten Joint Score and VAS. Radiograph evaluation includes the tibiofemoral angle, posterior condylar offset and its ratio, and notching frequency and measurement. A total of 119 patients were included: 60 in the CAS group and 59 in the cTKA. Mean follow-up was 5.61 years (Max 7.83–Min 5.02 years). No clinically relevant preoperative differences were observed between the groups. Postoperatively, both groups showed similar functional results (WOMAC, SF-12, FJS, KSS, and VAS) with similar complication rates. The CAS group had an increased surgery time by a mean of 12 min (107.02 ± 15.22 vs. 95.32 + 13.87; p = 0.00) as well as a higher notching frequency and size (40% vs. 13.60%; p = 0.013; 1.239 mm ± 1.7604 vs. 0.501 mm ± 1.4179; p = 0.031). CAS obtained similar functional, radiological, and complication rates to cTKA at the expense of increasing surgery time and notching frequency and size.

Although acromioclavicular joint (ACJ) dislocation is a common injury following trauma involving the shoulder, it is rare in the absence of trauma. In this manuscript, we describe a case of ACJ in a 15-year-old girl who presented a painful dislocation with spontaneous shortening of the right acromioclavicular joint that forced her to temporarily abandon her sports career. After failure of conservative physiotherapy treatment, surgical intervention was proposed by performing an arthroscopic-assisted button slide combined with augmented hamstring allograft reconstruction. After the intervention and the subsequent recovery period, the athlete was able to return to her semi-professional training. The follow-up of the patient is 5.5 years post-surgery. The result obtained could help in planning the treatment of future cases.
