Background: Arthroscopic knee surgeries are commonly performed orthopaedic procedures, which can be done under unilateral spinal anaesthesia (USA) or ultrasound-guided combined sciatic and femoral nerve block (USFB). However, not many studies have compared both these techniques. Hence this study was undertaken to compare USA and USFB in arthroscopic knee surgeries in terms of time to readiness for discharge (TRD).
Methods: Eighty patients were randomised into the USA ( = 40) and USFB groups ( = 40). They were administered either USA or USFB on the affected side. The TRD values were compared. Patients were considered fit for discharge after voiding urine, ambulation and obtaining a visual analogue scale (VAS) score of <3. The maximum time required for any of the three parameters was taken as the TRD for that particular patient.
Results: The mean TRD was 595.41 ± 195.69 min in the USA group and 351.86 ± 129.51 min in the USFB group ( < 0.001). The median VAS scores for postoperative pain assessment were lower in the USFB group at 2, 4, 12 and 24 h ( < 0.05). The number of patients requiring rescue analgesia was lower in the USFB group at 6 and 12 h after surgery ( < 0.05).
Conclusion: Patients undergoing arthroscopic knee surgeries under USFB have an advantage when it comes to TRD as these patients have comparatively better postoperative analgesia, less requirement of rescue analgesia, early voiding of urine and early ambulation.

Department of Orthopedics, Division of Sports Medicine and Shoulder Surgery, University of Colorado School of Medicine, Aurora, Colorado, U.S.A.
Purpose: To identify arthroscopic rotator cuff repair study groups and evaluate if study design or other study characteristics correlate with a repeat ipsilateral shoulder surgery.
Methods: A systematic search of the PubMed, Embase, and Cochrane Library databases was conducted on March 20, 2021, and April 2, 2021. The following search terms were used by 2 different researchers: ((Rotator cuff repair[Title/Abstract]) AND (Revision[Title/Abstract]) NOT (Systematic Review[Title/Abstract]) NOT (arthroplasty[Title/Abstract]).
Comparison of Synovialization and Clinical Outcomes between Anterior Cruciate Ligament Anteromedial Bundle Augmentation and Double-Bundle Anterior Cruciate Ligament Reconstruction.

Department of Orthopaedic Surgery, Pohang St. Mary's Hospital, Nam-gu, Pohang-si, Gyeongsangbuk-do, Republic of Korea.
This study aimed to compare clinical outcomes and second-look arthroscopic findings between double-bundle anterior cruciate ligament (ACL) reconstruction for complete ACL rupture and anteromedial (AM) bundle augmentation with preservation of the posterolateral (PL) bundle in isolated AM bundle rupture. Between 2014 and 2021, we retrospectively analyzed 95 ACL reconstructions with at least 2 years of follow-up. Patients undergoing primary ACL reconstruction from January 2014 to June 2021 were included in the study.

Objective To compare the five-year subjective functional outcomes of single-bundle anterior cruciate ligament reconstruction (ACLR) with three different femoral tunnel positions under arthroscopic guidance. Methods A retrospective study was conducted on the clinical data of 165 patients who underwent ACLR at the Department of Sports Traumatology,Sports Hospital,National Institute of Sports Medicine,General Administration of Sport of China from January 2012 to December 2017.According to femoral tunnel positions,the patients were assigned into three groups of low centre (LC)section (=53),high centre (HC) section (=45),and high anterior medial (HAM) section (=67).

Background: Treatment of stable osteochondritis dissecans (OCD) lesions of the knee in young patients poses the challenge of abstaining from competitive sports for months. Outcomes relevant to this patient population additionally include successful return to sport (RTS), return to the same level of sport, and the time needed to achieve both.
Purpose: To evaluate the adolescent population for RTS outcomes after treatment of stable OCD lesions of the knee and to compare RTS outcomes between patients treated nonoperatively and those who required surgery.
Background: Contamination of sterilized surgical instruments is not a typically suspected source of increased infection rate, especially if no abnormalities in the sterilization process are detected.
Purpose/hypothesis: The purpose of this study was to report increased infection rates after knee ligament reconstructions due to undetectable sterilization process errors leading to residual moisture, not limited to a specific surgical tool. It was hypothesized that (1) residual moisture on surgical tools due to autoclave overloading would not be detected by autoclave self-diagnostics, chemical and biological tests, or organoleptic assessment and (2) this kind of contamination may elevate infection rates, especially in knee intra-articular reconstruction procedures.
