Arthroscopic release of the deep medial collateral ligament to assist in exposure of the medial tibiofemoral compartment.

ABSTRACT: Arthroscopy of the knee is a widely used surgical procedure for addressing intra-articular pathology. In assessing the intra-articular structures, visualization is of paramount importance. The medial tibiofemoral compartment is often difficult to fully visualize in tight knees in which limited access can compromise surgical efficacy. Poor visualization can increase the possibility of a residual meniscal tear after attempted partial meniscectomy, as well as the possibility of iatrogenic chondral injury from arthroscopic instruments. We describe a technique that allows improved medial tibiofemoral visualization with release of the deep medial collateral ligament. We use standard arthroscopic portals, without the need for further incisions or stab holes and with minimal additional patient morbidity. This procedure allows easier exposure of the medial knee chondral surfaces and meniscus and easier use of arthroscopic instrumentation in the medial compartment.

Project description:PurposeTo quantify intraoperative joint space widening afforded by the outside-in, percutaneous release of the medial collateral ligament (MCL) and to evaluate its impact on medial compartment width and functional outcomes at 6-week follow-up for patients undergoing a partial medial meniscectomy without postoperative bracing.MethodsPatients with posteromedial meniscus tears and no evidence of ipsilateral knee pathology, undergoing partial medial meniscectomy, were enrolled. Intraoperatively, medial compartment width was quantified with fluoroscopy before and after the percutaneous MCL release with an 18-gauge spinal needle proximal to the joint line. At 6-week follow-up, valgus stress radiographs re-evaluated medial compartment width. International Knee Documentation Committee (IKDC) and Patient-Reported Outcomes Measurement Information System (PROMIS) scores were completed preoperatively and at 6-week follow-up to evaluate functional outcomes. A paired sample t test performed at a 95% confidence interval (CI) was used to compare these variables.ResultsForty-two patients, mean (± standard deviation) age 55.3 ± 10.7 years, were available for analysis of intraoperative medial compartment widening. Medial compartment width increased from 5.95 ± 1.32 to 11.09 ± 1.74 mm intraoperatively after MCL release. At 6-week follow-up, radiographic assessment demonstrated a mean medial compartment width of 5.85 ± .99 mm, which represented an insignificant change compared with the preoperative value (CI -0.68 to .33, P = .474). PROMIS and IKDC scores significantly improved from baseline, with increases of 6.9 ± 12.4 (CI 2.0 to 11.8, P = .008) and 11.7 ± 17.8 (CI 4.7 to 18.8, P = .002), respectively.ConclusionsPercutaneous MCL release during knee arthroscopy improves visualization and facilitates instrumentation by providing an almost 2× wider working space within the medial tibiofemoral joint. In this study, the performance of percutaneous MCL release did not result in any complications. Radiographic and clinical resolution of iatrogenic laxity was demonstrated by 6-weeks postoperatively, without the use of postoperative bracing.Level of evidenceIV, therapeutic case series.
