RESUMO
Background: Although several studies have noted that patients are routinely overprescribed opioids, few have reported usage after arthroscopic surgery. Purpose: To determine opioid consumption and allocation for unused opioids after common arthroscopic surgeries. Study Design: Case series; Level of evidence, 4. Methods: Patients between the ages of 15 and 40 years who were scheduled to undergo anterior cruciate ligament reconstruction (ACLR), labral repair of the hip or shoulder, meniscectomy, or meniscal repair were prospectively enrolled. Patients were prescribed either 5 mg hydrocodone-325 mg acetaminophen or 5 mg oxycodone-325 mg acetaminophen based on surgeon preference. Patients completed a daily opioid usage survey during the 2-week postoperative period. In addition, patients completed a survey on postoperative day 21 inquiring about continued opioid use and medication disposal, if applicable. Opioid medication consumption was converted to morphine milligram equivalents (MMEs). Results: Of the 200 patients who were enrolled in the study, 176 patients had sufficient follow-up after undergoing 85 (48%) ACLR, 26 (14.8%) hip labral repair, 34 (19.3%) shoulder labral repair, 18 (10.2%) meniscectomy, and 13 (7.4%) meniscal repair procedures. Mean age was 26.1 years (SD, 7.38); surgeons prescribed a mean of 26.6 pills whereas patients reported consuming a mean of 15.5 pills. The mean MME consumption in the 14 days after each procedure was calculated: ACLR (95.7; 44% of prescription), hip labral repair (84.8; 37%), shoulder labral repair (57.2; 35%), meniscectomy (18.4; 27%), and meniscal repair (32.1; 42%). This corresponded to approximately 39% of the total opioid prescription being utilized across all procedures. Mean MME consumption was greatest on postoperative day 1 in hip, shoulder, and meniscal procedures and on postoperative day 2 in ACLR. Only 7.04% of patients reported continued opioid use in the third postoperative week. Patients had a mean of 11 unused pills or 77.7 MMEs remaining. Of the patients with remaining medication, 24.7% intended to keep their medication for future use. Conclusion: The results of our study indicate that patients who undergo the aforementioned arthroscopic procedures consume <75 MMEs in the 2-week postoperative period, translating into a mean of 10 to 15 pills consumed. Approximately 60% of total opioids prescribed went unused, and one-fourth of patients intended to keep their remaining medication for future usage. We have provided general prescribing guidelines and recommend that surgeons carefully consider customizing their opioid prescriptions on the basis of procedure site to balance optimal postoperative analgesia with avoidance of dissemination of excess opioids.
RESUMO
Purpose: The purpose of this study was to determine whether a preoperative Caton-Deschamps index (CDI) ≥ 1.30, as measured by magnetic resonance imaging, is associated with rates of postoperative instability, revision knee surgery, and patient-reported outcomes in patients undergoing isolated medial patellofemoral ligament (MPFL) reconstruction. Methods: Patients who underwent primary medial patellofemoral ligament reconstruction (MPFLR) between 2015 and 2019 at a single institution were assessed. Only those with at least 2 year follow up were included. Patients who had undergone a previous ipsilateral knee surgery, concomitant tibial tubercle osteotomy and/or ligamentous repair/reconstruction at the time of MPFL reconstruction were excluded from the study. CDIs were evaluated by three investigators based on magnetic resonance imaging measurement. Patients with a CDI ≥ 1.30 were included in the patella alta group, while those with a CDI between 0.70 and 1.29 served as controls. A retrospective review of clinical notes was used to evaluate the number of postoperative instability episodes and revisions. Functional outcomes were measured by the International Knee Documentation Committee (IKDC) and 12-Item Short Form Health Survey (SF-12) physical and mental scores. Results: Overall, 49 patients (50 knees, 29 males, 59.2%) underwent isolated MPFLR. Nineteen (38.8%) patients had a CDI ≥ 1.30 (mean: 1.41, range: 1.30-1.66). The patella alta group was significantly more likely to experience a postoperative instability episode (36.8% vs 10.0%; P = .023) and was more likely to return to the operating room for any reason (26.3% vs 3.0%; P = .022) compared to those with normal patellar height. Despite this, the patella alta group had significantly greater postoperative IKDC (86.5 vs 72.4; P = .035) and SF-12 physical (54.2 vs 46.5; P = .006) scores. Pearson's correlation showed a significant association between CDI and postoperative IKDC (R 2 = 0.157; P = .022) and SF-12P (R 2 = .246; P = .002) scores. There was no difference in postoperative Lysholm (87.9 vs 85.1; P = .531). and SF-12M (48.9 vs 52.5; P = .425) scores between the groups. Conclusion: Patients with preoperative patella alta, as measured by CDI had higher rates of postoperative instability and return to the OR with isolated MPFL reconstruction for patellar instability. Despite this, higher preoperative CDI was associated with greater postoperative IKDC scores and SF-12 physical scores in these patients. Level of Evidence: Retrospective cohort study, Level IV.
RESUMO
Background: Several studies have reported excellent results after surgical repair of proximal hamstring avulsions. However, the effect on these patients of receiving workers' compensation has not yet been explored. Hypothesis: Workers' compensation patients undergoing proximal hamstring repair of complete tears will have similar outcomes when compared with a matched control group of non-workers' compensation patients. Study Design: Cohort study; Level of evidence, 3. Methods: Workers' compensation patients who underwent complete proximal hamstring avulsion open repair between 2010 and 2019 were identified (WC group). A control group was matched by age (±3 years), sex, and body mass index (BMI; ±3). Demographics and patient-reported outcome measures were compared, including standard and custom Marx activity rating scale (MARS), standard and custom lower extremity functional scale (LEFS), and visual analog scale (VAS) for pain. Rate and time to return to work were recorded. Results: The WC group was composed of 20 patients (8 men, 12 women) with a mean age of 52.3 years and BMI of 32.4. The 20 matched controls (8 men, 12 women) who underwent repair had a mean age of 50.6 years and a mean BMI of 31.2. There was no difference between the groups regarding age (P = .924), sex (P > .999), or BMI (P = .330). The WC group reported similar mean MARS (3.3 vs 5.4; P = .174), custom MARS (87.5 vs 97.0; P = .215), and VAS pain (3.3 vs 3.8; P = .698) scores compared with controls. However, the WC group had significantly lower standard LEFS (69.1 vs 94.1; P < .001) and custom LEFS (62.3 vs 87.9; P < .001) scores, returned to work at a lower rate (70.0% vs 94.1%; P = .039), and required more time to return to work after repair (4.3 vs 3.5 months; P = .029) compared with controls. Conclusion: Workers' compensation patients who underwent open proximal hamstring repair for complete avulsions experienced inferior patient-reported outcomes, required more time to return to work, and returned to work at a lower rate than a matched control group.
RESUMO
Purpose: To compare functional outcomes, complications, and revision rates between allograft reconstruction and graftless fixation techniques for the treatment of Rockwood grades III-V acute acromioclavicular (AC) joint separation. Methods: Patients who underwent graftless or allograft surgery acutely (≤6 weeks from injury) for Rockwood type III-V AC joint separations from 2012 to 2018 were retrospectively reviewed. Clinic notes and operative reports were identified to confirm the surgical technique and presence of complications including revision, infection, and fracture. In addition, postoperative radiographs were assessed to determine any instances of loss of adequate reduction, and several patient-reported outcomes were collected. Results: In total, 115 patients (52 allograft, 63 graftless) were included in this study with a mean follow-up of 3.8 ± 2.5 years. There were no differences between allograft and graftless patients regarding rates of loss of reduction >5 mm (11.1% graftless vs 21.2% allograft), revision (3.2% vs 1.9%), infection (1.6% vs 3.9%), fracture (3.2% vs 7.7%), or total complication (7.9% vs 9.6%) rates (all P > .05). Patient-reported outcome measures also did not significantly differ between groups. Multivariate analysis found that increased time from injury to repair and increased Rockwood injury grade (grades IV and V) were associated with increased CC distance at postoperative follow-up (P = .008, .050, and .047, respectively). Conclusion: Multivariate analysis found that patients who underwent acute AC joint fixation without allograft augmentation had similar functional outcomes, complications, and revision rates compared with patients who underwent AC joint reconstruction with allograft. Level of Evidence: Level III, retrospective comparative study.
RESUMO
Purpose: To retrospectively investigate the clinical and functional outcomes of patients who underwent knotted medial-row rotator cuff repair (KT-RCR) compared with patients who underwent knotless medial-row rotator cuff repair (KL-RCR). Methods: A retrospective chart review of patients who underwent double-row transosseous-equivalent rotator cuff repair in 2016 was performed at a single institution with 2-year follow-up. Information regarding demographic characteristics, preoperative tear size (magnetic resonance imaging), surgical variables (including method of suture stabilization), preoperative and postoperative American Shoulder and Elbow Surgeons (ASES) scores, and all complications (e.g., cuff failure, adhesive capsulitis, and persistent pain) was compiled. Results: A total of 189 patients met the inclusion criteria: 72 in the KL-RCR group and 117 in the KT-RCR group. No significant difference in preoperative ASES scores was found between the KL-RCR and KT-RCR groups (48.3 vs 45.4, P = .327). Postoperative ASES scores did not differ between the groups (82.4 for KL-RCR vs 78.8 for KT-RCR, P = .579). We found no significant difference in cuff failure rates after 2 years, determined by magnetic resonance imaging (5.6% for KL-RCR vs 6.1% for KT-RCR, P > .999), or complication rates (11.1% for KL-RCR vs 8.6% for KT-RCR, P = .743). Conclusions: The knotted approach and knotless approach to double-row rotator cuff repair showed similar outcome scores, cuff failure rates, and complication rates at minimum 2-year follow-up. Level of Evidence: Level III, retrospective therapeutic comparative trial.
RESUMO
Purpose: To provide an updated review of multimodal pain management in arthroscopic surgery by evaluating pain and opioid consumption after shoulder, knee, and hip arthroscopy. Methods: A comprehensive literature search was performed to identify randomized controlled trials (RCTs) investigating multimodal pain management after shoulder, knee, and hip arthroscopy. Articles were identified from January 2011 through December 2020 using various databases. As the primary outcome variables of this study, differences in postoperative pain and opioid consumption volumes were summarized from all reported postoperative time points. Results: 37 shoulder, 28 knee, and 8 hip arthroscopy RCTs were included in the study. The most frequent bias present in the included RCTs was incomplete outcome data (58%), while group allocation concealment was the least frequent bias (15%). Qualitative analysis of rotator cuff repair (n = 12), anterior cruciate ligament reconstruction (n = 11), meniscectomy (n = 5), femoroacetabular impingement (n = 2), oral medications (n = 8), postoperative interventions (n = 10), and nonpharmacological interventions (n = 6) was performed. Conclusions: Many multimodal pain management protocols offer improved pain control and decreased opioid consumption after arthroscopic surgery. On the basis of the current literature, the evidence supports an interscalene nerve block with a dexamethasone-dexmedetomidine combination for rotator cuff repair, a proximal continuous adductor canal block for anterior cruciate ligament reconstruction, and local infiltration analgesia (e.g., periacetabular injection with 20 mL of .5% bupivacaine) for hip arthroscopy. When evaluating oral medication, the evidence supports 150 mg Pregabalin for shoulder arthroscopy, 400 mg Celecoxib for knee arthroscopy, and 200 mg Celecoxib for hip arthroscopy, all taken preoperatively. There is promising evidence for the use of various nonpharmacological modalities, specifically preoperative opioid education for rotator cuff repair patients; however, more clinical trials that evaluate nonpharmacological interventions should be performed. Level of Evidence: Level II, systematic review of Level I and II studies.
RESUMO
PURPOSE: Osteochondral allograft (OCA) transplantation is a restorative technique for addressing articular cartilage defects by transferring mature viable chondrocytes with subchondral bone into size-matched lesions. The purpose of this study was to compare differences in clinical and functional outcomes in patients treated with OCA for osteochondral defects compared with isolated chondral pathology. METHODS: A retrospective review identified patients who underwent OCA transplantation and grouped them into osteochondral or isolated chondral pathology. Demographic data, surgical history, lesion characteristics, complications, and rate of subsequent surgery were reviewed. The review included 86 patients (24 osteochondral, 62 chondral) with a mean follow-up of 5.4 ± 1.4 years. Outcome measures included the Knee Injury and Osteoarthritis Outcome Score for Joint Replacement (KOOS, JR.), International Knee Documentation Committee (IKDC), and Short Form Health Survey (SF-12) physical scores. Failure was defined to include revision OCA, graft removal, conversion to ACI, or conversion to arthroplasty. RESULTS: The average age at surgery was 32.3 and 37.3 years for the osteochondral and chondral groups, respectively (P = 0.056). The medial femoral condyle was the most common defect location in both groups. P < 0.05 was considered statistically significant. Patients with osteochondral pathology had significantly greater KOOS JR., IKDC, and SF-12 scores (P < 0.05), and fewer failures were reported in the osteochondral group (8.3% versus 32.3%, P = 0.045). When controlling for age, sex, laterality, BMI, and presence of a concomitant procedure, patients with osteochondral pathology were found to have better KOOS and IKDC scores, but there was no difference in SF12 scores or rates of failure between groups. CONCLUSION: The findings of this study indicate that patients undergoing OCA for osteochondral defects may have greater functional outcomes and similar failure rates compared with OCA transplantation for isolated chondral pathology.
RESUMO
BACKGROUND: The use of telemedicine for postoperative visits is increasing, especially in rural areas. Few studies have investigated its use for arthroscopic shoulder patients. This study aims to evaluate patient satisfaction with telemedicine for postoperative clinic visits following arthroscopic shoulder procedures in a rural setting. METHODS: Patients were prospectively enrolled using the following exclusion criteria: <18 years, open procedures, and non-compliance follow-up at 6 weeks postoperatively. All patients completed a 13-question satisfaction survey, while telemedicine patients completed an additional, separate seven-question survey. Patients who switched groups completed a four-question prompt to determine the reasons for switching. Differences between groups were evaluated by either Student t-test or Mann-Whitney U-test. RESULTS: The study enrolled 32 patients, with five patients following up by telemedicine and 27 in person. Age and distance from clinic were similar between patients who were assigned to the telemedicine group, completed the telemedicine visit, and opted for in-person visits (all p>0.05). Patient satisfaction did not vary significantly based on care by the surgeon, concerns being addressed, thoroughness of visit, overall clinical assessment at a prior visit, and improvements in pain and physical function (all p>0.05). Among patients who opted out of telemedicine visits, the most common reason was a preference to meet in-person but these patients agreed that telemedicine visits are a good idea. CONCLUSIONS: Regardless of type of follow-up, individuals reported similar levels of satisfaction with treatment during the visit and improvements in pain and physical function.
RESUMO
Background: The ability to return to school after orthopaedic surgery is an important consideration for young patients, as there is substantial literature indicating that school attendance is correlated strongly with academic performance. Purpose: To evaluate the time to return to school, the barriers that students encounter when returning to school, and the academic effect of anterior cruciate ligament reconstruction (ACLR) in high school (HS) and college students. Study Design: Cohort study; Level of evidence, 2. Methods: Full-time HS and college/graduate school (C/GS) students who underwent ACLR during the 2017 to 2018 and 2018 to 2019 academic periods were included in the study. Patients were contacted 2 weeks postoperatively to complete a questionnaire that assessed their time to return to school and barriers that interfered with their ability to return, and they completed a second questionnaire at 6 weeks postoperatively that assessed academic performance and challenges faced upon returning to school. Results: Included were 36 (52.2%) full-time HS students and 33 (47.8%) full-time C/GS students. HS students reported a longer time to return to school compared with C/GS students (8.51 vs 5.89 days; P = .008). In addition, HS students missed more scheduled school days than C/GS students (5.39 vs 2.90 days; P < .001). The majority of HS (73.5%) and C/GS (65.5%) students cited pain as a barrier to return, and more than half of HS (70.6%) and C/GS (55.2%) students also cited restricted mobility as a barrier to return. HS students were more likely to miss an examination in the early postoperative period compared with their C/GS counterparts (65.7% vs 39.3%; P = .037). Many students in both cohorts received a grade less than expected in the early postoperative period; this was not significantly different between the 2 groups (HS, 50.0%; C/GS, 42.9%; P = .489). Conclusion: ACLR can have a negative effect on school attendance and academic performance among HS and C/GS students. Orthopaedic surgeons should counsel all students and their families adequately about the potential academic effect of orthopaedic surgery in order to maximize clinical results, academic performance, and satisfaction in their patients.
RESUMO
BACKGROUND: Articular cartilage pathology can result from a spectrum of origins, including trauma, osteochondritis dissecans, avascular necrosis, or degenerative joint disease. PURPOSE: To compare the differences in clinical and patient-reported outcomes after autologous chondrocyte implantation (ACI) versus osteochondral allograft transplantation (OCA) in patients with focal articular cartilage defects without underlying bone loss. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: A retrospective review identified patients who underwent ACI or OCA between 2008 and 2016 for isolated grades 3 and 4 articular cartilage defects without underlying bone loss. Outcome measures included the Knee injury and Osteoarthritis Outcome Score for Joint Replacement (KOOS JR), International Knee Documentation Committee (IKDC) evaluation, and 12-Item Short Form Health Survey-Physical Component (SF-12-P) scores. Defect location, size, complications, and rate of subsequent surgery were determined. RESULTS: Overall, 148 patients were included: 82 (55%) underwent ACI and 66 (45%) underwent OCA. The mean age at the time of surgery was 31.2 years within the ACI cohort and 37.7 years within the OCA cohort (P < .001); the mean follow-up for both cohorts was 6.7 years (P = .902). Within the ACI group, 28 (34%) patients had multifocal defects, 21 (26%) had defects confined to the femoral condyles, and 33 (40%) had defects in the patellofemoral region. Within the OCA group, 23 (35%) patients had multifocal defects, 30 (46%) had confined femoral condyle lesions, and 13 (20%) had patellofemoral defects. When comparing by lesion location, there were no significant differences in KOOS JR, and IKDC scores between the ACI and OCA cohorts (P < .05). There was, however, a significant difference for SF-12-P scores for FDD trochlear lesions. In both cohorts, traumatic patellofemoral pathology demonstrated lower patient-reported outcomes and higher failure rates than degenerative lesions. The overall rate of failure, defined as graft failure with revision surgery and/or conversion to arthroplasty, was significantly greater in the OCA group (21% vs 4%; P = .002). CONCLUSION: Study results indicated that ACI provides similar outcomes to OCA with or without concomitant procedures for the treatment of symptomatic articular cartilage defects in all lesion locations and may have a lower revision rate for multifocal and condylar lesions.
RESUMO
Diabetes increases the risk of developing postoperative complications such as superficial and deep infection, wound dehiscence, and revisional surgery. Prolonged non-weightbearing and/or augmented fixation may reduce postoperative complications in complicated diabetic ankle fractures. This study's purpose was to compare the development of postoperative infection, wound dehiscence, and revisional surgery in complicated diabetic ankle fractures with respect to weightbearing status. We hypothesized that fewer complications would occur in patients with prolonged non-weightbearing. Medical records of 90 surgically treated complicated diabetic ankle fractures were retrospectively reviewed for postoperative radiographs, weightbearing status, and complications. Complicated diabetes was defined as HbA1c ≥ 8% within 1 year of surgery. Twenty-four out of 90 patients had prolonged non-weightbearing status, which was defined as ≥ 8 weeks of non-weightbearing postoperatively. Twelve out of 90 patients had augmented fixation, which was defined as standard open reduction and internal fixation plus ≥ 2 tetra-cortical or > 2 tri-cortical syndesmotic screws with medial plate, external fixation, or other combination. Thirty-three out of 90 patients (36.7%) patients developed complications postoperatively. Patients with prolonged non-weightbearing had less complications (29.2% vs 39.4%, p = .37) and larger HbA1c values compared with early weightbearing patients (10.0 vs 9.3, p = .04). A one-unit increase in creatinine value (mg/dL) revealed a 3.15-fold increase in development of complications (95% confidence interval 1.29-7.65, p = .01). Although not statistically significant, complicated diabetic ankle fractures treated with prolonged non-weightbearing had less complications postoperatively except for ankle Charcot. Creatinine can be utilized as an independent risk factor for postoperative complications in this population.

BACKGROUND: The distinction between race and ethnicity should be carefully understood and described for demographic data collection. Racial healthcare differences have been observed across many orthopaedic subspecialties. However, the frequency of reporting and analyzing race and ethnicity in orthopaedic clinical trials has not been determined. Therefore, the primary purpose of this systematic review was to determine how frequently race and ethnicity are reported and analyzed in orthopaedic clinical trials. METHODS: The top 10 journals by impact factor in the field of orthopaedics were manually screened from 2015 to 2019. All randomized controlled trials related to orthopaedics and assessing clinical outcomes were included. Eligible studies were evaluated for bias using the Cochrane risk-of-bias tool and for whether the trial reported and analyzed several demographics, including age, sex, height, weight, race, and ethnicity. The frequency of reporting and analyzing by each demographic was accessed. In addition, comparisons of reporting and analyzing race/ethnicity were made based on orthopaedic subspecialty and journal of publication. RESULTS: A total of 15,488 publications were screened and 482 met inclusion criteria. Of these 482 trials, 460 (95.4%) reported age and 456 (94.6%) reported sex, whereas 35 (7.3%) reported race and 15 (3.1%) reported ethnicity for the randomized groups; 79 studies (16.4%) analyzed age and 72 studies (14.9%) analyzed sex, whereas 6 studies (1.2%) analyzed race and 1 study (0.2%) analyzed ethnicity. The orthopaedic subspecialty of spine was found to report race (23.5%) and ethnicity (17.6%) more frequently than all the other subspecialties, whereas sports medicine reported race and/or ethnicity in only 3 of 150 trials (2.0%). CONCLUSIONS: Race and ethnicity are not frequently reported or analyzed in orthopaedic randomized controlled trials. Social context, personal challenges, and economic challenges should be considered while analyzing the effect of race and ethnicity on outcomes.

PURPOSE: To compare the measurements of the Caton-Deschamps index on preoperative magnetic resonance imaging and radiographs of patients undergoing operative management of patellar instability. METHODS: Patients who underwent primary medial patellofemoral ligament reconstruction and/or tibial tubercle osteotomy between January 2015 and November 2019 were assessed. Caton-Deschamps indices were measured by 3 independent reviewers on both radiographs and magnetic resonance imaging. Intra- and interclass correlation coefficients and a Bland-Altman analysis were calculated to assess inter-rater reliability and measurement agreement between radiographic and magnetic resonance imaging. RESULTS: Seventy-two patients (73 knees) were identified. The average Caton-Deschamps index was 1.23 ± 0.18 on radiograph and 1.26 ± 0.18 on magnetic resonance imaging. Strong inter-rater reliability was observed between reviewers for both radiographic and magnetic resonance imaging Caton-Deschamps indices (intraclass correlation coefficients 0.700 and 0.715, respectively). Pooled observer measurements revealed a moderate agreement between radiographic and magnetic resonance imaging for patella to tibia distance, weak agreement for patellar articular cartilage distance, and strong agreement for the Caton-Deschamps index (intraclass correlation coefficients 0.687, 0.485, and 0.749, respectively). Bland-Altman analysis demonstrated a mean difference in Caton-Deschamps index of -0.03 ± 0.15 (95% limits of agreement: -0.29 to 0.23) between radiographic and magnetic resonance imaging, meaning that Caton-Deschamps indices were on average 0.03 lower on radiographic than on magnetic resonance imaging. CONCLUSIONS: The Caton-Deschamps index has strong agreement between radiographic and magnetic resonance imaging in patients undergoing patellar stabilization surgery. Either modality can be reliably used to preoperatively assess patellar height. LEVEL OF EVIDENCE: Level IV, diagnostic case series.
RESUMO
BACKGROUND: Several cadaveric imaging studies have demonstrated that the articular cartilage thickness on the tibial plateau varies depending on coverage by native meniscal tissue. These differences are thought to partially contribute to the rates of cartilage degeneration and development of osteoarthritis after meniscectomy. Because there is greater tibial plateau coverage with meniscal tissue in the setting of a discoid meniscus, these findings may also have implications for the long-term health of the knee after saucerization of a torn discoid meniscus. PURPOSE: To evaluate the relationship between lateral compartment articular cartilage thickness and the presence or absence of a discoid meniscus. STUDY DESIGN: Cross-sectional study; Level of evidence, 3. METHODS: Included in the study were 25 patients younger than 40 years of age who had undergone a 1.5-T or 3-T knee magnetic resonance imaging (MRI) between 2010 and 2016 at a single institution and had an intact, lateral discoid meniscus. Only patients with an otherwise asymptomatic lateral compartment were included. The authors then identified 35 age-matched controls with a nondiscoid, intact lateral meniscus who underwent knee MRI at the same institution and during the same period. The articular cartilage thicknesses in 6 zones of the lateral femoral condyle (LFC) and lateral tibial plateau (LTP) were measured for each patient by 2 musculoskeletal radiologists, and the mean thicknesses were compared between the study and control groups. RESULTS: The average age at MRI was 22.63 years (range, 8.30-35.90 years) for the discoid group and 20.93 years (range, 8.43-34.99 years) for the nondiscoid group. The nondiscoid group had significantly greater mean articular cartilage thickness in all 6 zones of the LTP (P < .05 for all). When comparing the zones of the LFC, there was no significant difference in the mean thickness in any zone between the 2 groups. CONCLUSION: Patients with discoid menisci had thinner baseline articular cartilage thickness in the LTP compared with those patients without discoid menisci.
