Tibial tubercle osteotomy (TTO) with medial patellofemoral ligament reconstruction (MPFLr) has not been well described for this indication. This paper describes a surgical technique to address the unique challenges faced when performing TTO and MPFLr in the prosthetic knee. Technique: This technique and video describe a TTO and MPFLr via an extensile incision and medial sub-vastus approach. A 6 cm long TTO is performed, if indicated, to medialise the extensor mechanism up to 1 cm and fixed with ×2 4.5 mm cortical screws. For the MPFLr, a quadriceps tendon autograft is utilized, with the natural insertion to the superior pole of the patella being left undisturbed. The graft is first attached with an interference screw and then reinforced with an endobutton to provide crucial cortical fixation to overcome the problem of low bone mineral density encountered in this area of the femur following TKA. Results: Five patients underwent MPFLr using the described technique. No failures or recurrence of instability occurred at the last follow-up. Pre-operative mean patella tilt and shift were 44° and 3.5 cm, respectively. Post-operatively, mean tilt and shift were 4.1° and 0.4 cm, respectively. There was one wound dehiscence requiring surgical debridement and closure. Conclusion: This paper describes a surgical technique to perform a TTO and MPFLr for patella instability post-TKA. The described method highlights key adaptations to address the unique challenges in this patient population.","PeriodicalId":46378,"journal":{"name":"SICOT-J","volume":" ","pages":""},"PeriodicalIF":1.6,"publicationDate":"2022-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43457473","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: Thirty-seven patients underwent hip arthroplasty for femoral neck fractures between April 2020 and February 2021.

Acetabular cartilage abnormalities were classified as either overall degeneration or partial damage according to the cartilage damage classification system. Results: Acetabular cartilage abnormalities, including overall degeneration or partial damage, were found in all hips (100%). Out of the 33 hips, overall degeneration, partial damage, and labral abnormalities were detected in 32 (96.9%), 16 (48.4%), and 9 (27.2%) hips, respectively.

Patients usually recover, but the possibility of not reobtaining a full range of motion exists. Thus, early shoulder exercises are necessary to achieve their full range of motion. This study aims to understand the effects of suprascapular nerve block (SSNB) augmentation at the spinoglenoid notch in hydrodilatation to treat frozen shoulder to facilitate early shoulder exercises. Methods: The current study retrospectively observed 31 patients, including 40–60-year-old patients diagnosed and treated with primary frozen shoulder. The participants were divided into groups A (hydrodilatation) and B (hydrodilatation and the augmentation of an SSNB). Shoulder function and pain scores were assessed before, during, and after the intervention (at months 1 and 6). Results: The result of this study shows that suprascapular nerve block plays a role in decreasing pain in intraintervention (0.69 vs. 5.73; p < 0.05), month 1 of follow-up (3.44 vs. 6.40; p < 0.05), but not significant on month 6 of group A and B after intervention (5.88 vs. 7.20; p > 0.05). Better delta functional scores were noted in the therapy group during month 1 of the follow-up (delta American shoulder and elbow surgeons [ASES]: 19.29 vs. 34.40, p < 0.05; delta disabilities of the arm, shoulder, and hand [DASH]: 17.88 vs. 38.15, p < 0.05). The difference in functional score on month 6 between both groups was not significantly different (delta ASES: 31.97 vs. 30.31, p > 0.05; delta DASH: 36.63 vs. 38.92, p > 0.05). Discussion: One rationale for using an SSNB augmentation at spinoglenoid notch in hydrodilatation for treating frozen shoulder was to obtain pain relief immediately to facilitate early manual exercise.

Electromechanical delay (EMD) is an integral part of the peroneal motor response and, therefore, substantial in preventing ankle sprains. This study aimed to investigate the effect of laterality on EMD times before and after fatigue. Methods: Fifteen healthy male volunteers participated in the study. Measurements were taken with the ankle in a neutral (0°) position, and all subjects followed an isokinetic fatigue protocol. Repeated ANOVA was used for statistical analysis, and the α level was set a priori at p ≤ 0.05. Results: No significant difference was noted in EMD times between the dominant and non-dominant legs of the volunteers (p = 0.940). Fatigue caused a significant increase in EMD by 10–15 ms (p = 0.003), while the leg × fatigue interaction was not significant (p = 0.893). Conclusions: In a non-injured athlete, both ankles seem to be under the same protection of the reactive response of the peroneal muscles. Therefore, athletes should be aware that both their extremities are equally exposed to the danger of an ankle injury. Also, fatigued ankles demonstrate longer EMD times, implying that improving resistance to fatigue may add another layer of protection that has the potential to prevent ankle sprain recurrence.","PeriodicalId":46378,"journal":{"name":"SICOT-J","volume":" ","pages":""},"PeriodicalIF":1.6,"publicationDate":"2022-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41832087","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
