The posterior cruciate ligament is the strongest ligament in the knee, and it has a peculiar clinical problem: it is routinely missed.

A typical story runs like this. A road accident, or a fall onto a bent knee. X-rays in casualty show no fracture, so the patient is reassured and sent home with a soft-tissue injury diagnosis. Weeks pass. The knee aches after activity and feels unreliable going down stairs. Only much later does an MRI reveal a ligament that nobody examined for.

Dr. Sunil Choudhary, FRCS (Trauma & Orthopaedics), a UK-trained knee surgeon. This page explains PCL injury treatment in Faridabad — how the PCL tears, why it is missed, and when it genuinely needs surgery.

What the PCL does

The posterior cruciate ligament runs from the back of the shin bone to the front of the thigh bone, through the centre of the knee. Its job is to stop the shin bone sliding backwards relative to the thigh. It is around twice as strong as the ACL, which is one reason it tears less often — and also one reason a significant tear can produce surprisingly modest symptoms.

How PCL injuries happen

Dashboard injury — the classic mechanism

In a road traffic accident with the knee bent, the shin is driven backwards against the dashboard. The force passes directly through the PCL. In India, where two-wheeler and car accidents are a common cause of knee injury, this remains the single most frequent mechanism.

Hyperflexion — the sports mechanism

Landing on a fully bent knee with the foot pointed downwards drives the shin backwards. Seen in falls from height, gymnastics and awkward landings.

Hyperextension — high-energy injury

Forced hyperextension loads the PCL severely and frequently produces multi-ligament injury — PCL with ACL, or PCL with the posterolateral corner. These are serious injuries requiring specialist assessment.

Grading a PCL injury

  • Grade I — partial tear, 0 to 5 mm of backward translation. Usually managed without surgery
  • Grade II — partial tear, 5 to 10 mm. Usually managed without surgery
  • Grade III — complete tear, more than 10 mm. Surgical reconstruction considered, particularly in combined injuries

How we diagnose PCL injury

Examination is the key, and it is the step most often omitted. As a PCL injury doctor in Faridabad, the tests I rely on are:

  • Posterior drawer test — with the knee bent to 90 degrees, pushing the shin backwards and comparing displacement with the uninjured side. The most important single test
  • Posterior sag sign — with both knees bent, the shin on the injured side visibly drops back
  • Quadriceps active test — contracting the quadriceps pulls the sagged shin forward, confirming PCL disruption
  • Dial test at 30 and 90 degrees — assessing whether the posterolateral corner is also injured, which completely changes management
  • Varus and valgus stress testing for collateral ligament integrity

There is an important trap here. If the examiner performs an anterior drawer test starting from an already-sagged position, pulling the shin back to neutral feels like forward laxity — and the injury gets misdiagnosed as an ACL tear. How this differs from an ACL tear.

MRI confirms the tear and identifies the associated injuries: posterolateral corner structures, meniscus tears, cartilage damage, and the characteristic bone bruising on the front of the shin that matches a dashboard mechanism.

Non-surgical treatment — which works well for most PCL injuries

Unlike the ACL, the PCL has a reasonable blood supply and genuine healing potential. The majority of isolated Grade I and II tears — and some Grade III tears in lower-demand patients — do well without surgery, provided the rehabilitation is done correctly.

One principle governs the whole programme: the hamstrings pull the shin backwards, which is exactly the direction a healing PCL cannot tolerate. Open-chain hamstring exercises are therefore avoided in the early phase, and quadriceps strengthening is emphasised instead. This is the detail most generic physiotherapy programmes get wrong.

  • Weeks 0–4 — hinged brace locked in full extension to prevent the shin sagging backwards. Quadriceps sets and straight-leg raises. Swelling control
  • Weeks 4–8 — progressive range of movement. Closed-chain quadriceps work: mini-squats, leg press. No open-chain hamstring curls
  • Weeks 8–16 — progressive resistance training, proprioception and balance work. Return to light activity
  • Months 4–6 — sport-specific training. Return to sport based on functional testing rather than dates

When PCL reconstruction is needed

Surgery is recommended for complete Grade III tears in patients wanting competitive sport, for PCL injury combined with posterolateral corner injury — which rarely settles with rehabilitation alone — for bicruciate injuries involving both PCL and ACL, and where PCL laxity is causing progressive medial compartment arthritis.

What the reconstruction involves

A graft is used to rebuild the ligament. Appropriate graft choices are hamstring tendon, quadriceps tendon, or an allograft such as Achilles or tibialis. The technical challenge unique to PCL surgery is the so-called “killer turn” — the sharp angle the graft makes as it exits the tibial tunnel, which concentrates stress at that bend. This is managed either with careful tunnel positioning or with a tibial inlay technique that avoids the turn altogether.

Recovery is slower than ACL surgery: brace for around six weeks, partial weight-bearing for four to six weeks, running at around four to five months, and return to sport at nine to twelve months.

Why PCL injuries are missed — and what to do about it

Three reasons. X-rays are normal, so soft-tissue injury is assumed to be minor. Symptoms are less dramatic than an ACL tear — often no pop, often no immediate massive swelling. And the specific examination tests are not routinely performed outside specialist practice.

If you have had a dashboard injury, a fall onto a bent knee, or a hyperflexion injury in sport, and you notice instability going downstairs or aching after activity — ask specifically for a PCL examination and consider an MRI rather than relying on a normal X-ray.

Frequently asked questions

Can a PCL tear heal on its own?

Partially, yes — more so than an ACL. Many Grade I and II tears heal to a functionally stable knee with correct rehabilitation. Complete tears usually leave some residual laxity, which may or may not matter depending on your activity.

How is PCL injury different from ACL injury?

The ACL stops the shin sliding forwards; the PCL stops it sliding backwards. ACL tears cause giving way on turning and pivoting. PCL tears cause difficulty going down stairs and down slopes, and aching after activity. The ACL rarely heals; the PCL often does.

Do I need surgery for a PCL tear?

Most isolated PCL tears do not. Surgery is for complete tears in athletes, combined ligament injuries, and knees where instability is causing ongoing damage.

Where is PCL treatment available in Faridabad?
