Anterior Cruciate Ligament Repair Using a Re-tensionable All-Suture Construct.

Anterior cruciate ligament (ACL) tears are among the most common injuries to the knee. With recent improvements in imaging that allow for more precise identification of ACL tear patterns, improved techniques for repair, and advancements in biological augmentation, there has been a re-emerging interest in primary ACL repair, especially for acute proximal ACL tears. This article aims to describe a surgical technique for primary ACL repair using a re-tensionable all-suture-based construct.

Rehabilitation Protocols for Superior Capsular Reconstruction Are Variable: A Systematic Review.

PURPOSE: To screen manuscripts that discuss rehabilitation protocols for patients who underwent superior capsular reconstruction (SCR) to elucidate whether a standard rehabilitation algorithm exists for SCR. METHODS: A systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta Analyses (i.e., PRISMA) guidelines. PubMed (MEDLINE) and Embase were searched using pertinent Boolean operation terms "superior capsular reconstruction" and "rotator cuff repair rehabilitation," and articles that included rehabilitation protocols following superior capsular reconstruction surgery were reviewed. Two independent reviewers performed the search and quality assessment. RESULTS: A total of 549 articles were yielded after our database search. Fourteen studies fulfilled our inclusion criteria and were included in the review. Study designs included 9 editorials, 3 case series, and 2 case reports. Each study included in this review used a unique rehabilitation algorithm that posed significant variability between the protocols. Four phases were identified to summarize each protocol and were used as a basis of discussion-sling versus brace time (3-6 weeks for comfort/removal vs complete immobilization), passive range of motion (immediately after surgery to initiation at 6 weeks), active range of motion (4-8 weeks), and strengthening/return to full activity (12-52 weeks). Initiation of rehabilitation, length of time spent in each phase, types of exercises, and overarching goals for return to function were significantly variable and were decided upon by the surgeon based on current massive rotator cuff repair protocols. Presently, there is no standard rehabilitation protocol for SCR. CONCLUSIONS: SCR is a relatively new procedure that is gaining rapid popularity with promising outcomes. Based on our review, there is no standard rehabilitation protocol in place; thus, it is not possible to recommend an evidence-based rehabilitation protocol following SCR at this time. LEVEL OF EVIDENCE: Level V, systematic review of Level IV and V studies.

Peroneal Tendinosis and Subluxation.

Peroneal tendinosis and subluxation are lifestyle-limiting conditions that can worsen if not properly diagnosed and treated. Adequate knowledge of ankle anatomy and detailed history and comprehensive physical examination is essential for diagnosis. Peroneal tendinopathy is likely to result from overuse, whereas subluxation often precipitates from forceful contraction of peroneals during sudden dorsiflexion while landing or abruptly stopping. In athletes, conservative measures remain first-line treatment of tendinopathy, but surgery is often immediately indicated in cases of recurrent symptomatic subluxation or dislocation. Surgical technique varies on the type, mechanism, and severity of injury, but most procedures have a high success rate.

Diagnosis of Traumatic Ankle Arthrotomies Using Saline Load Tests, Methylene Blue, and Radiopaque Tracer: A Cadaveric Study.

BACKGROUND: The objective of this study was to define the volume (mLs) needed for a positive saline load challenge test in anterolateral (AL), anteromedial (AM), posterolateral (PL), or posteromedial (PM) ankle arthrotomy wounds using normal saline (NS) and methylene blue (MB). Another objective was to evaluate the use of fluoroscopy and iodinated contrast in the diagnosis of ankle arthrotomies. METHODS: Four cadaveric ankle specimens underwent standardized arthrotomy creation in either the AL, AM, PL, or PM portion of each specimen. An 18-gauge needle was used to inject fluid into each ankle, and the volumes needed for positive fluid challenges were recorded. All 4 ankles were tested 10 times (n = 40) with NS and 10 times using MB (n = 40). A fifth cadaveric ankle was injected with radiopaque contrast solution, and an arthrotomy was simulated and imaged with fluoroscopy.Statistical analyses compared the volumes of NS and MB needed for a positive test. In addition, the 25th, 50th, 75th, 90th, and 95th percentiles of volumes needed for a positive test was calculated. RESULTS: The volume of fluid necessary to detect 25%, 50%, 75%, 90%, and 95% of ankle arthrotomies from any site was 2.0 mL, 4.5 mL, 9.0 mL, 10 mL, and 10 mL, respectively. Anterior arthrotomies required less fluid (2.1 mL ± 0.5) than posterior arthrotomies (9.0 mL ± 1.2) for a positive test (P < .0001). There was no difference between the amount of NS (5.5 mL ± 3.6) vs MB (5.6 mL ± 3.7) needed for a positive challenge test (P = .739). CONCLUSION: Ninety-five percent of ankle arthrotomies could be diagnosed with 10 mL of injected fluid; there was no difference between the volume of NS vs MB needed. Fluoroscopy assisted with needle placement and can be combined with radiopaque contrast solution to diagnose ankle arthrotomies. CLINICAL RELEVANCE: The findings of this study may improve sensitivity and efficiency in the diagnosis of traumatic ankle arthrotomies, for which there is currently a paucity of literature.
