Patient function continues to improve over the first five years following tibial plateau fracture managed by open reduction and internal fixation

A newly designed anatomical plate for the therapy of posterolateral tibial plateau fracture via a supra-fibular-head approach: a retrospective study

The posterolateral tibial plateau fracture is a special type of intra-articular fracture, for which there is no simple, safe, and effective standardized procedure. In this paper, we evaluate the clinical efficacy and the advantages of the treatment of posterolateral tibial plateau fracture by using our designed proximal lateral tibial rim plate for the posterolateral condyle of the tibial plateau via the space above the fibula head. Thirty-eight patients with posterolateral tibial plateau fractures from June 2018 to June 2021 were retrospectively analyzed. CT scans were used to classify the degree of injury in the included patients. All of them were fixed with reduction using an approach above the fibula head combined with a homemade anatomical plate. The regular postoperative review was performed to instruct functional knee exercises. Postoperative complications were observed and follow-up visits were performed to assess the functional outcome. A total of 38 patients with posterolateral tibial plateau fractures, 13 males and 25 females were included in the study. All patients were followed up for 13-26 months, with a mean of 15.3 months. There were no postoperative complications such as numbness of the limb, knee joint instability, etc. X-ray review showed that the fractures were all healed, and the healing time was 10-16 weeks, with an average of 12.1 weeks; none of the internal fixation loosening and loss of articular surface occurred during the follow-up period. At the last follow-up, according to the HSS knee function score criteria, the scores were 79-98, with an average of 91.3. The HSS score presented excellent in 34 cases (89%) and good in 4 cases (11%). The Rasmussen score was graded as excellent in 29 cases (76%) and good in 9 cases (24%). In conclusion, The treatment of posterolateral tibial plateau fractures by an approach above the fibula head has the advantages of simplicity and safety, small trauma, and no risk of vascular and nerve injuries, and the anatomical proximal lateral tibial rim plate can play a direct and effective supporting role for the bone fragments of the posterolateral condyle, and the combination of both of them has obvious advantages in the treatment of posterolateral condylar fracture of the tibial plateau, and it is a method worth borrowing and popularizing.

Deep Surgical Site Infection after Fracture Has a Profound Effect on Functional Outcomes

Background

Fracture-related infection is one of the most challenging complications in orthopaedic trauma surgery. However, the effect of infection on functional and pain-related outcomes has not been well established. The aims of this study were to evaluate functional recovery for patients with fracture and a deep surgical site infection compared with patients with fracture without infection and to evaluate whether pain severity, social support, and preinjury mental health have a moderating effect on the magnitude and direction of the relationship between deep surgical site infection and functional recovery.

Methods

This is a secondary retrospective cohort study using prospectively collected data from the VANCO trial (Local Antibiotic Therapy to Reduce Infection After Operative Treatment of Fractures at High Risk of Infection) and the OXYGEN (Supplemental Perioperative Oxygen to Reduce Surgical Site Infection After High Energy Fracture Surgery) trial. In this study, 2,116 patients with tibial plateau, pilon, or calcaneal fractures at high risk for infection were included. Patients were divided into cohorts of patients who experienced a deep surgical site infection and those who did not. The primary outcome measure was the functional outcome using the Veterans RAND 12-Item Health Survey (VR-12).

Results

After controlling for covariates, deep surgical site infection was independently associated with functional outcome, with a 3.3-point reduction in the VR-12 Physical Component Score, and pain severity was independently associated with functional outcome, with a 2.5-point reduction in the VR-12 Physical Component Score. Furthermore, the Brief Pain Inventory pain severity demonstrated an important moderating effect on the relationship between infection and functional outcome. In patients with lower pain scores, infection had a large negative impact on functional outcome, whereas, in patients with higher pain scores, infection had no significant impact on functional outcome. Furthermore, the functional outcome in the entire cohort remains at only 61% of baseline.

Conclusions

This study documents the negative impact of postoperative infection on functional recovery after injury, as well as the novel finding of pain severity as an important moderating factor. This study emphasizes not only the importance of developing effective interventions designed to reduce postoperative infection, but also the role that factors that moderate pain severity plays in limiting recovery of physical function.

Risk for total knee arthroplasty after tibial plateau fractures: a systematic review

PURPOSE

Tibial plateau fractures (TPFs) may lead to posttraumatic osteoarthritis and increase the risk for total knee arthroplasty (TKA). The aim of this systematic review was to analyse the conversion rate to TKA after TPF treatment.

METHODS

A systematic search for studies reviewing the conversion rate to TKA after TPF treatment was conducted. The studies were screened and assessed by two independent observers. The conversion rate was analysed overall and for selected subgroups, including different follow-up times, treatment methods, and study sizes.

RESULTS

A total of forty-two eligible studies including 52,577 patients were included in this systematic review. The overall conversion rate of treated TPF to TKA in all studies was 5.1%. Thirty-eight of the forty-two included studies indicated a conversion rate under 10%. Four studies reported a higher percentage, namely, 10.8%, 10.9%, 15.5%, and 21.9%. Risk factors for TKA following TPF treatment were female sex, age, and low surgeon and hospital volume. The conversion rate to TKA is particularly high in the first 5 years after fracture.

CONCLUSION

Based on the studies, it can be assumed that the conversion rate to TKA is approximately 5%. The risk for TKA is manageable in clinical practice.

Radiographic Evidence of Early Posttraumatic Osteoarthritis following Tibial Plateau Fracture Is Associated with Poorer Function

To determine if radiographic evidence of posttraumatic osteoarthritis (PTOA) following tibial plateau fracture correlates with poorer clinical and functional outcomes, patients with tibial plateau fractures were followed at 3, 6, and 12 months. All patients had baseline radiographs and computed tomography scan. Radiographs obtained at each follow-up were reviewed for healing, articular incongruence, hardware positional changes, and the development of postinjury arthritic change. Cohorts were determined based on the presence (PTOA) or absence (NPTOA) of radiographic evidence of PTOA. Demographics, fracture classification, complications, additional procedures, and functional status were compared between cohorts. Sixty patients had radiographic evidence of PTOA on follow-up radiographs at a mean final follow-up of 24.2 months. The NPTOA cohort was composed of 210 patients who were matched to the PTOA cohort based on age and Charlson comorbidity index. Mean time to fracture union for the overall cohort was 4.86 months. Cohorts did not differ in Schatzker classification, time to healing, injury mechanism, or baseline Short Musculoskeletal Function Assessment (SMFA). Patients with PTOA had a greater degree of initial depression and postoperative step-off, higher incidence of initial external fixator usage, higher rates of reoperation for any reason, and higher rates of wound complications. Associated soft tissue injury and meniscal repair did not coincide with the development of PTOA. Range of motion and SMFA scores were significantly worse at all time points in patients with PTOA. Although fracture patterns are similar, patients who required an initial external fixator, had a greater degree of initial depression or residual articular incongruity, underwent more procedures, and developed an infection were found to have increased incidence of PTOA. Radiographic evidence of osteoarthritis correlated with worse functional status in patients. The goal of surgery should be restoration of articular congruity and stability to mitigate the risk of PTOA, although this alone may not prevent degenerative changes. Patients with early loss of range of motion should be aggressively treated as this may precede the development of PTOA.

Five-year outcomes for patients with a displaced fracture of the distal tibia

Aims

To report the outcomes of patients with a fracture of the distal tibia who were treated with intramedullary nail versus locking plate in the five years after participating in the Fixation of Distal Tibia fracture (FixDT) trial.

Methods

The FixDT trial reported the results for 321 patients randomized to nail or locking plate fixation in the first 12 months after their injury. In this follow-up study, we report the results of 170 of the original participants who agreed to be followed up until five years. Participants reported their Disability Rating Index (DRI) and health-related quality of life (EuroQol five-dimension three-level questionnaire) annually by self-reported questionnaire. Further surgical interventions related to the fracture were also recorded.

Results

There was no evidence of a difference in patient-reported disability, health-related quality of life, or the need for further surgery between participants treated with either type of fixation at five years. Considering the combined results for all participants, there was no significant change in DRI scores after the first 12 months of follow-up (difference between 12 and 24 months, 3.3 (95% confidence interval -1.8 to 8.5); p = 0.203), with patients reporting around 20% disability at five years.

Conclusion

This study shows that the moderate levels of disability and reduced quality of life reported by participants 12 months after a fracture of the distal tibia persist in the medium term, with little evidence of improvement after the first year.

Recovery Curve for Patients With Pilon Fractures Using Patient-Reported Outcome Measurement Information System

BACKGROUND

The time frame in which patients can expect functional improvement after open reduction internal fixation (ORIF) of pilon fractures is unclear. The purpose of this study was to determine the trajectory and rate at which patients' physical function improves up to 2 years postinjury.

METHODS

The patients studied sustained a unilateral, isolated pilon fractures (AO/OTA 43B/C) and followed at a level 1 trauma center over a 5-year period (2015-2020). Patient-Reported Outcomes Measurement Information Systems (PROMIS) Physical Function (PF) scores from these patients at defined follow-up times of immediately, 6 weeks, 3 months, 6 months, 1 year, and 2 years after surgery defined the cohorts and were retrospectively studied.

RESULTS

There were 160 patients with PROMIS scores immediately postoperatively, 143 patients at 6 weeks, 146 patients at 12 weeks, 97 at 24 weeks, 84 at 1 year, and 45 at 2 years postoperatively. The average PROMIS PF score was 28 immediately postoperatively, 30 at 6 weeks, 36 at 3 months, 40 at 6 months, 41 at 1 year, and 39 at 2 years. There was a significant difference between PROMIS PF scores between 6 weeks and 3 months (P < .001), and between 3 and 6 months (P < .001). Otherwise, no significant differences were detected between consecutive time points.

CONCLUSION

Patients with isolated pilon fractures demonstrate the majority of their improvement in terms of physical function between 6 weeks and 6 months postoperatively. No significant difference was detected in PF scores after 6 months postoperatively up to 2 years. Furthermore, the mean PROMIS PF score of patients 2 years after recovery was approximately 1 SD below the population average. This information is helpful in counseling patients and setting expectations for recovery after pilon fractures.

Tibial plateau fractures in the elderly have clinical outcomes similar to those in younger patients

BACKGROUND

The purpose of this study was to compare outcomes following surgical treatment of tibial plateau fractures in an elderly (≥ 65y) and non-elderly (< 65) population.

METHODS

Patients with tibial plateau fractures were prospectively followed. Patients were included if they were operatively treated, had an Injury Severity Score of < 16, and had follow-up through 12 months. Clinical, radiographic, and functional outcomes were evaluated at the 3, 6, and 12-month follow-up points.

RESULTS

Mean time to radiographic fracture union was by 4.68 and 5.26 months in young and elderly patients, respectively (p = 0.25). There was no difference in self-reported baseline SMFA (p = 0.617). SMFA scores were better in younger patients at 3 months (p = 0.031), however this did not hold when multivariate modeling controlled for other factors. There was no difference at 6 and 12 months (p = 0.475, 0.392). There was no difference in range of knee motion at 3 months. At 6 and 12 months, young patients had statistically but not clinically better range of knee motion (p = 0.045, 0.007). There were no differences in overall reoperation rates, conversion arthroplasty, post-traumatic osteoarthritis or wound complications.

CONCLUSIONS

Age greater than 65 does not appear to portend poorer outcomes after surgical repair of a tibial plateau fracture. The complication profiles are similar. Elderly and younger patients had similar function at 12 months compared to their baseline. These data suggest that age should not be a disqualifying factor when considering whether a patient with a tibial plateau fracture should be treated operatively.

Treatment of tibial plateau fractures: A comparison of two different operation strategies with medium-term follow up

Background

The objective of this study was to compare the clinical and radiological outcomes of two surgical methods for tibial plateau fractures (TPFs): minimally invasive surgery (MIS) using a double reverse traction repositor and traditional open reduction internal fixation (ORIF).

Methods

From our prospectively collated database, 187 consecutive adult patients with 189 operatively treated TPFs in our level I trauma center were included from January 2015 to March 2018 who had a minimum of three years’ follow-up. All cases were performed by the senior surgeon using either MIS (group 1, 84 patients with 84 TPFs) or ORIF (group 2, 103 patients with 105 TPFs). Details of the demographics, injury mechanism, pre- and postoperative follow-up imaging, operative procedures and complications were collected. The final results from the 36-Item Short-Form Health Survey (SF-36), Western Ontario and McMaster Universities Osteoarthritis index (WOMAC) and Hospital for Special Surgery (HSS) were obtained at the final follow-up.

Results

Clinically, significant differences were observed in the WOMAC (pain, P ​= ​0.001; stiffness, P ​< ​0.001), HSS (P ​= ​0.003) and SF-36 (P ​= ​0.001). Radiologically, significant intergroup differences were observed in the loss of immediate postoperative reduction rates, secondary loss of reduction rates and signs of osteoarthritis (Kellgren–Lawrence). Two and ten superficial infections in group 1 (2.4%) and group 2 (9.5%), respectively, and 6 lateral popliteal nerve palsy cases occurred (0 MIS, 6 ORIF), with significant intergroup differences.

Conclusion

Our study shows that the MIS using a double reverse traction repositor is promising and safe technique for the TPFs when used for the correct indications.

The translational potential of this article

The current status of using a minimally invasive surgery for the treatment of TPFs have been analyzed and a new method of using a double reverse traction repositor for the treatment of TPFs have been proposed in this study, which updated treatment concept of TPFs.

Risk Factors for Wound Complications Following Conversion TKA after Tibial Plateau Fracture

INTRODUCTION

The purpose is to investigate the incidence of wound complications for total knee arthroplasty (TKA) following tibial plateau open reduction and internal fixation (ORIF).

MATERIALS AND METHODS

A prospective arthroplasty registry was queried for patients with CPT codes for primary TKA, tibial plateau ORIF, removal of hardware (ROH), and diagnosis of post-traumatic arthritis. Patients were included if they had undergone tibial plateau ORIF and subsequent TKA. Chart review was performed to obtain demographic, clinical and post-operative information.

RESULTS

Twenty-one patients were identified, with average age of 56.23 ± 13.2 years at time of tibial plateau ORIF and 62.91 ± 10.8 years at time of TKA. Seven (33.3%) patients had a tibial plateau fracture-related infection (FRI). Eight (38.1%) patients underwent ROH prior to TKA. Seven (33.3%) patients' TKA incision incorporated the prior plateau incisions. Eight (36.4%) patients developed wound complications following TKA and 5 (23.8%) developed an acute periprosthetic joint infection (PJI) following TKA and had the plateau incision incorporated into the TKA incision. FRI history did not increase the rate of wound complications but did increase the rate of ROH prior to TKA.

CONCLUSIONS

Previous FRI involving tibial plateau repair surgery doesn't correlate with PJI after conversion TKA for post traumatic OA. Surgeon-controlled factors such as staged ROH and incision placement can help reduce the rate of wound complications following TKA performed after tibial plateau ORIF.

[Open reduction and internal fixation with plate via posteromedial approach of retaining pes anserinus tendon in the treatment of tibial plateau fracture]

OBJECTIVE

To compare the effects of cutting and retaining the pes anserinus tendon on effectiveness following tibial plateau fracture.

METHODS

A clinical data of 40 patients with tibial plateau fracture treated with open reduction and internal fixation with plate via posteromedial approach between January 2015 and January 2020 was retrospectively analyzed, including 18 patients retained the pes anserinus tendon (study group) and 22 patients cut the pes anserinus tendon (control group) during operation. There was no significant difference in gender, age, side of affected knee, cause of injury, Schatzker classification, time from injury to operation, and associated ligament injury between the two groups ( P>0.05). The operation time, intraoperative blood loss, hospital stay, anatomic reduction rate, incidence of complications, fracture healing time, knee flexion and extension range of motion at 2 weeks and 12 months, and knee extension range of motion at 3 months after operation were recorded and compared between the two groups. The visual analogue scale (VAS) score was used to evaluate the early postoperative pain improvement at 1, 3, and 14 days after operation and hospital for special surgery (HSS) score was used to evaluate the improvement of knee function at 3, 6, and 12 months after operation.

RESULTS

The patients in both groups were followed up 12-15 months with an average of 12.8 months. There was no significant difference in operation time, intraoperative blood loss, and fracture healing time between the two groups ( P>0.05). The hospital stay in the control group was significantly longer than that in the study group ( t=8.339, P=0.000). There was no significant difference in the anatomic reduction rate (90.9% vs. 83.3%) between the control group and the study group ( χ ²=0.058, P=0.810). There were 1 case of proximal tibial osteomyelitis, 3 cases of skin necrosis, 3 cases of traumatic arthritis, and 2 cases of lower deep venous thrombosis after operation in the control group, and 1 case of metaphyseal nonunion, 2 cases of traumatic arthritis, and 1 case of lower deep venous thrombosis in the study group, showing no significant difference in the incidence of complications (40.9% vs. 22.2%) between the two groups ( χ ²=1.576, P=0.209). In the study group, knee flexion and extension range of motion at 2 weeks and 12 months and knee extension range of motion at 3 months after operation were significantly better than those of the control group ( P<0.05). VAS scores and HSS scores in both groups improved with time after operation ( P<0.05), in addition, the HSS score and VAS score of the study group were significantly better than those of the control group ( P<0.05).

CONCLUSION

Compared with traditional pes anserinus tendon cutting group, pes anserinus tendon retaining group can significantly reduce postoperative short-term pain, improve postoperative knee range of motion and knee function within 1 year after operation.

Major depressive disorder, when under treatment, may not affect functional outcomes in patients with tibial plateau fractures

BACKGROUND

The purpose of this study is to determine if treated psychological depression is associated with poorer functional outcomes in patients who sustain tibial plateau fractures.

METHODS

Patients with a tibia plateau fracture were prospectively followed. Functional status was assessed using the Short Musculoskeletal Function Assessment (SMFA) at baseline (pre-injury), 3 months, 6 months, and 1 year post injury. Clinical outcomes were recorded at each follow up visit and radiographic outcomes were obtained from follow up radiographs. Records were reviewed to identify patients who were being treated for major depressive disorder (MDD). SMFA scores and clinical outcomes were compared between the depression and no depression cohorts.

RESULTS

420 patients were treated for a tibial plateau fracture and the mean age was 50.83 ± 15.60 years. Forty-two (10%) patients with 42 fractures were being treated for MDD at the time of their fracture. Patients with MDD were older (p = 0.05) and were more likely female (p < 0.01). At baseline, the clinical depression cohort had worse Total SMFA scores compared to the non-depressed cohort (5.90 ± 14.41 vs. 2.69 ± 8.35, p < 0.01). There were no differences in total SMFA score or any SMFA subscores at 3, 6, and 12 months. The incidence of wound complications, reoperations, and radiographic outcomes also did not differ between the cohorts.

CONCLUSION

Despite patients with MDD reporting higher SMFA (poorer) scores at baseline, MDD was not associated with worse injuries, diminished clinical or poorer functional outcomes following tibial plateau fractures.

Anti-gravity treadmill rehabilitation improves gait and muscle atrophy in patients with surgically treated ankle and tibial plateau fractures after one year: A randomised clinical trial

OBJECTIVE

To compare the one-year postoperative outcomes of anti-gravity treadmill rehabilitation with those of standard rehabilitation in patients with ankle or tibial plateau fractures.

DESIGN

An open-label prospective randomised study.

SETTING

Three trauma centres.

SUBJECTS

Patients were randomised into the intervention (anti-gravity treadmill) or control (standard protocol) rehabilitation group.

MAIN MEASURES

The primary endpoint was changes in the Foot and Ankle Outcome Score for ankle fractures and Knee Injury and Osteoarthritis Outcome Score for tibial plateau fractures from baseline to 12 months after operation. Secondary endpoints were the subscores of these scores, muscle atrophy (leg circumference at 20 cm above and 10 cm below the knee joint) and the Dynamic Gait Index.

RESULTS

Initially, 73 patients (37 vs 36) underwent randomisation. After 12 months, 29 patients in the intervention group and 24 patients in the control group could be analysed. No significant difference was noted in the Foot and Ankle Outcome Score (80.8 ± 18.4 and 78.4 ± 21.1) and Knee Injury and Osteoarthritis Outcome Score (84.8 ± 15.2 and 81.7 ± 17.0). The change in the Dynamic Gait Index from 12 weeks to 12 months differed significantly between the groups (P = 0.04). Patients with tibial plateau fractures had a 3 cm wider thigh circumference in the intervention group than those in the control group (95% confidence interval: -0.2 to 6.3 cm, P = 0.08).

CONCLUSION

One year after surgery, patients who had undergone anti-gravity treadmill rehabilitation showed better gait than patients in the control group, and those with tibial plateau fractures had less muscle atrophy.
