When we look around the literature for treatment of plantar plate injuries, in that location is a large corporeality of work with regarding the surgical management plantar plate injuries, withal very little with regards to the Conservative management. Currently, there are just two papers published, both were unmarried case studies.
Commencement we had Ojofeitimi, Bronner, & Becica (2016) looking at treatment of a professional dancer with a iind MPTJ plantar plate injury, with 6 and 12 month follow-up and at 12 months the dancer was still competing at their elite level on 16 weeks and 37 physical therapy sessions. The authors described 3 phases to the rehabilitation process.
Phase ane: protection – lasting approximately 2 weeks
This was focusing on reducing the hurting and protecting the iind MTPJ, no foot exercises, with the focus on more than proximal control work. There was no dancing or benefit walking and the patient was in a post-operative boot.
Phase 2: restricted duty – lasting approximately two weeks
Some human foot doming and towel gyre exercises were introduced along with increasingly proximal control work. The simply activeness was barre work, along with the weaning out of the post-operative kick into trainers. To help protect the toe strapping was used.
Phase 3: – modified duty/return to performance
Resistance ring toe flexion exercises were added in this phase alongside increasing the proximal control work and reducing the padding and strapping over time. A return to all dance activeness was achieved past the cease of sixteen weeks.

The 2nd instance written report by (Jordan, Thomas, & Fischer, 2017) involved offloading in a surgical boot, with series MRIs over a ane year catamenia. They reported, "total clinical restoration of function and radiologic prove of healing".
As nosotros tin see there is limited literature around bourgeois direction, however, I exercise believe that conservative direction of plantar plate injuries can be effective in dispensary. The majority of plantar plate injuries nosotros tend to see in dispensary are related to runners and dancers.
We are currently in the process of auditing our own data in clinic to run into how effective our conservative plantar plate treatment regime is. Having a quick look at this data, the time for return back to play/activeness if you just have it isolated plantar plate injury is 10 – 14 weeks, even so, if you have a pre-existing lower limb pathology, ranging from osteoarthritis, hallux valgus, tendinopathy the render to play/activity timescale ranges from 12 weeks upwards to 49 weeks. We exercise programme to publish, we are however collecting data and then we tin can effort and take a wait a case series, over a range of sports and activities, too with follow-upward, to check activity levels afterward treatment.
I am at present going to speak almost the protocol that we employ in dispensary to help try to manage plantar plate injuries. I will mention the use of foot orthoses, however, if yous want a more in-depth web log around the use of foot orthoses for managing and helping plantar plate injuries, delight run into my previous commodity. Also if yous want an overview of plantar plate injuries meet the first blog in this series.
It is also worth noting not all of the plantar plate injuries that I see in clinic are diagnosed using ultrasound or MRI, and I do not transport all of my patients for imaging, every bit research (Klien et al 2013) has shown that pain, positive digital Lachmans (anterior draw) test and small swelling, has been shown to place 95% of plantar plate injuries. The majority of plantar plate injuries that we see in dispensary are chronic injuries, rather than acute tears.
To assist with our own audit information, nosotros were using the digital buy toe force test, to help assess weight-bearing plantar flexion strength of the toes. However, more recently in clinic we are trying to quantify forcefulness using a handheld dynamometer and are currently testing different means to assess this.
Like with all rehabilitation plan I explain to our patients that there are iii – 4 stages. Firstly we need to help reduce the hurting, and then increase strength then assist return dorsum to their sport/activeness. If in that location has been an acute tear, we also try a period of immobilisation. However nosotros'll know that it is not blackness-and-white during the rehabilitation stages but for the purpose of the blog, every bit I know both patients and clinicians read this I volition explain my 3 stages as pain reduction, increment strength and return to play.
Stage i – Pain reduction
Every bit part of the offloading process, I do have strict communication of no barefoot walking for around 4 – 6 weeks, depending on symptoms. I used to use a lot of carbon lining with a forefoot rocker, to help sagittal plane function and reduce flexion of the lesser MTPJs during propulsion, as this is commonly the phase of the gait cycle that aggravates most plantar plate injuries.
Hoka take released their Carbon 10 trainer, which I accept found gives really good results, with it helping to reduce pain and go people dorsum to walking earlier. Information technology is also worth noting that new remainder take just released their Fuel Cell TC shoe, nevertheless, the rocker doesn't look equally much as the Carbon X. During writing this we are in the middle of the COVID-19 lockdown in the UK and I have not been able to get hold of a pair withal, I am aware that Nike have their 4% and Zoom fly trainer just I institute the midsole of these trainers to be too narrow.
I as well recommend patients to tape their toe in a plantar flexed position, changing the record on a daily basis.
Also, as mentioned in the previous plantar plate blogs, this is the phase where I will event foot orthoses if required.
From an exercise perspective, I get patients to starting time working on increasing pes intrinsic muscle strength by doing standing foot shortening exercises, or every bit I telephone call them toe push-ups.
I often start bottom toe flexion exercises with a low resistance band, nevertheless if also painful, I will start with no band.
I also use this fourth dimension to start working on whatsoever proximal strength requirements.
Stage ii – Increase Strength
Equally already mentioned yous can see that there is no clear delineation between phase I and stage Two. Equally if nosotros offset to increment force we are still going to have possibly a couple of weeks of taping or no barefoot walking remaining.
As we first to at present focus on increasing the force, nosotros start to increase the resistance on the band loops, for me information technology is important that the RPE (rate of perceived discussion) is kept vii/10. One time someone can do 15 toe flexion exercises comfortably nosotros move to a tougher resistance band progress them upwards to the highest level of resistance available.
One time the patient is able to utilize the highest resistance ring on the toe flexion exercises I start testing my patients ability to do dogie raises. I start double legs in shoes, either the Hoka Carbon 10 or with the carbon lining, only to assistance with confidence. This can be quite a fearful practice for patients to do every bit they know previously that this has hurt. Then equally symptoms and forcefulness improve we progress to double leg barefoot and so to single leg barefoot. This is the one exercise that I find we can get a flareup of hurting then I'm quite cautious in the introduction of this, even so I do believe information technology's extremely important that our patients are doing this, as the motion of going up onto your toes is involved in walking and the majority of sports, in particular running.
I keep my patients doing the toe push-upwards exercises, they tend to do around 3 – 500 in total per day, broken into batches of 20-thirty, I let my patients do them with shoes on and integrate them into their day.
I too introduce balance work using a wobble question, I did used to attempt and start this earlier, nonetheless I was finding that this was flaring upward the pain.
Stage iii – Return to play / activeness
By this time my patients have usually stopped taping the toe completely, and we have weaned them off the carbon lining if we are using one.
I view this stage as actually trying to build the chapters up to allow the patient to return dorsum to their activity and sport. From an exercise viewpoint nosotros are still focusing on the toe flexion exercises with the band loops and quite often by this stage I'1000 getting some patients to double bands upwardly to increase the strength even farther. We may first to add together some plyometric exercises and progress to barefoot single leg calf raises on the edge of a step with some additional weight.
And then, like any rehabilitation programme we advise on a graded render back to their activity. I do usually keep the patient in their orthoses whilst they are getting back to their activity in sport, however nosotros are finding that patients who were using the Hoka Carbon Ten, we can expect to wean off the human foot orthoses once they are back to their full level of activity in sport, or just apply the orthoses for intense training periods. This is actually individual and we accept not establish a item blueprint, then on removing the foot orthoses I'm really guided by my patient'due south feedback. We practise have some patients who do require the foot orthoses longer-term, from my feel these would tend to be the patients that have a ist MTPJs pathology, as this would have played a large part in why the plantar plate would have been injured in the outset place.
Nosotros also then repeat our strength testing and every time nosotros have establish a increase in strength through the plantar flexors. I do believe this helps to really empower the patient to show they have made progress, they are stronger and they are back to their activeness.
Finally, and probably nigh importantly is discussing a maintenance programme. We know information technology is extremely of import that the patients still continue with exercises to maintain their new levels strength and to help possible endeavor reduce the hazard of further injury. I still advise the patient to keep some tape and the carbon linings, which they can employ if they have a flareup, however with everyone going through the process they report that they experience empowered to manage this themselves going forward.
Equally y'all tin see there are no definitive timelines as to when to motility on from each phase. The process that we run in our clinic is that, on boilerplate, patients are seen for five sessions over a menstruation of 3 – 4 months, with the length between each appointment gradually increasing.
Taking a quick glance at my data in the patients with plantar plate injuries we accept managed in this way, the majority of them are however doing the aforementioned level of activity if not more half-dozen months down the line and have not reinjured.
Every bit I mentioned at the beginning of the blog we practise intend to try and publish our data, however we are hoping to go more long-term data first. And then we can try to paint a moving-picture show and suggest a possible conservative direction protocol for managing plantar plate injuries conservatively, as there is very little evidence to guide usa currently.
Summary
I do recollect there is place for conservative management of plantar plate injuries and I recollect it tin exist quite successful. For me the primal points are in the early stages to offload using a carbon lining or shoe such as Hoka carbon X which have proven to be very benign to my patients.
We actually practise need to focus the rehabilitation side of things on working on the intrinsic muscles and toe flexors and then most importantly towards the middle and cease of the plan ensuring that people tin exercise dogie raises and plyometrics. From experience if in that location is going to be a flareup it is unremarkably when we get-go introducing the calf enhance piece of work, so e'er endeavour and start shod so progress guide past patient response.
