MCL & LCL Ligament Surgery
Collateral ligament injuries graded properly. Most MCL tears heal in a hinged brace; outer-side LCL and posterolateral corner injuries are time-sensitive.
The collateral ligaments run down either side of the knee: the MCL on the inner side, the LCL on the outer side as part of the posterolateral corner. They control side-to-side stability, and they are injured constantly — a blow to the outside of the knee in football, a foot caught while turning, a fall from a two-wheeler with the leg trapped.
The good news is that most MCL injuries heal well without surgery. The problem is the ones that do not fit that rule: LCL and posterolateral corner injuries, which behave quite differently, and collateral injuries that come as part of a multiligament knee. Dr. Nitin N Sunku grades these properly on examination and imaging, treats the majority in a hinged brace with a staged rehabilitation programme, and operates on the minority that genuinely need it.
Conditions We Treat
MCL Sprain (Grade I–II)
Pain and tenderness along the inner side of the knee after a valgus force, with mild to moderate opening on stress testing but a firm end point. Swelling is usually localised rather than a tense joint effusion. These heal reliably with bracing and rehabilitation.
Complete MCL Tear (Grade III)
Marked opening on valgus stress with no firm end point. Often part of a larger injury — the classic combination is an MCL tear with an ACL tear, sometimes with a medial meniscus injury. The MCL portion still frequently heals in a brace; the accompanying injuries are what drive the surgical plan.
LCL and Posterolateral Corner Injury
Injury to the outer side of the knee, often from a blow to the inside of the knee or a hyperextension-varus force. Far less forgiving than the MCL. Patients may describe the knee snapping into hyperextension, difficulty on uneven ground, and sometimes foot drop or numbness if the common peroneal nerve has been stretched. These are assessed urgently.
Multiligament Knee Injury and Chronic Instability
Collateral injury combined with cruciate injury, or an old collateral injury that has healed lax, leaving a knee that opens up on side-to-side loading. High-energy injuries — road traffic accidents in particular — need a vascular and nerve assessment before anything else is planned.
The single most useful distinction is inner versus outer. An isolated inner-side (MCL) injury usually heals in a brace. An outer-side (LCL and posterolateral corner) injury has a much poorer record with non-surgical treatment and should be assessed early.
Treatment Approach / Procedures Offered
Non-Surgical Management (Most MCL Injuries)
The MCL has a good blood supply and heals well when protected. Treatment is a hinged knee brace allowing controlled movement while blocking side-to-side stress, early range of motion to prevent stiffness, and a progressive strengthening programme. Immobilising the knee rigidly is a mistake — stiffness after an MCL injury is more disabling than mild residual laxity. Grade I injuries often settle in three to four weeks, grade II in six to eight.
Early Repair for Acute LCL and Posterolateral Corner Injuries
Where the outer-side structures are completely torn, repair or reconstruction within the first two to three weeks gives materially better results than a delayed procedure, because the tissue planes are still identifiable. This is one of the genuine time-critical decisions in knee ligament surgery, and it is the reason an outer-side injury should not be watched for six weeks to see how it goes.
Collateral Ligament Reconstruction
For chronic instability, or where a healed-lax ligament leaves the knee opening under load, the ligament is reconstructed with a graft rather than repaired. In the posterolateral corner this may involve reconstructing more than one structure. Alignment is assessed first: a varus knee with a lax outer side may need the alignment corrected, because reconstructing soft tissue under a bow-legged load is a recognised route to failure.
Staged Treatment in Combined Injuries
Where the MCL is torn alongside the ACL, the usual approach is to brace and let the MCL heal first, then reconstruct the ACL on a knee that has regained full movement. Operating on a stiff, acutely inflamed knee increases the risk of arthrofibrosis. The sequencing is explained clearly, because it means two phases rather than one.
Why Choose Our Clinic
Collateral ligament injuries get two opposite errors: outer-side injuries treated too casually, and inner-side injuries operated on unnecessarily. Dr. Sunku’s fellowship training in arthroscopy and sports medicine, and his experience with professional athletes, is directed at getting that call right — grading the injury properly, recognising a posterolateral corner injury early enough for repair to be an option, and being straightforward when a brace and a rehabilitation programme will do the job better than surgery.
Recovery and Rehabilitation Overview
Week 0–2
Hinged brace, controlled range of motion, swelling management, and quadriceps activation. Weight-bearing as tolerated for isolated MCL injuries; protected for outer-side and combined injuries.
Week 2–6
Range of motion progressed to full, brace range opened up, closed-chain strengthening and hip control work. Most isolated grade I–II MCL injuries are walking normally well within this window.
Week 6–12
Brace weaned, strength work loaded properly, and straight-line running introduced for isolated injuries once side-to-side testing is comfortable and strength is adequate.
Month 3–6
Agility, cutting and sport-specific drills for non-surgical injuries. After reconstruction, this phase is where strengthening and controlled loading are the focus rather than return to sport.
Month 6–9
Return to contact sport after reconstruction, following strength testing and clearance. Isolated grade I–II MCL injuries typically return far sooner — often within one to two months.
These ranges assume an isolated ligament injury. A collateral injury combined with an ACL or PCL reconstruction follows the cruciate timeline, which is longer. Stiffness is the complication to watch for after collateral injuries, so early controlled movement matters more than rest.

Orthopedic and sports medicine care in Bengaluru
Dr. Nitin N Sunku is a consultant orthopedic surgeon and sports medicine specialist. His day-to-day work spans knee and shoulder arthroscopy, ACL and other ligament injuries, meniscus tears, cartilage-friendly repair options when suitable, hip and knee arthritis assessment, joint replacement when quality of life is clearly limited, fracture and trauma review, and spine symptom evaluation with a staged plan. Care is built around a clear history, a focused examination, imaging only when it changes management, and honest discussion of non-operative versus operative paths.
Where appointments take place
The practice is anchored at Raghava Multispeciality Hospital, Attibele, on Sarjapura–Attibele Road, for many patients travelling from Attibele, Anekal, Chandapura, Jigani, Bommasandra, Electronic City, Sarjapura, and nearby towns who want a South Bengaluru base close to home or work. Health Nest Hospital, HSR Layout (24th Main Road, Sector 2) supports selected consultations and follow-up for people who live closer to HSR, Koramangala, BTM Layout, Bellandur, or Whitefield-side commutes. Both sites link into imaging and physiotherapy networks when referrals are needed.
Conditions and procedures people commonly ask about
Typical questions cover ACL tears and post-injury instability, meniscus repair versus partial trimming, recurrent shoulder dislocation, rotator cuff tears and frozen shoulder, shoulder arthroscopy for impingement, tennis or golfer's elbow flare-ups, runner's knee and shin splints, Achilles and other tendon overuse problems, early to advanced hip and knee arthritis, partial and total knee replacement timing, hip replacement for arthritis and selected fractures, acute collarbone and ankle fractures, workplace and road traffic injuries, and back pain with or without leg symptoms when urgent red flags have been excluded. Sports medicine visits often blend training-load advice with targeted rehabilitation goals rather than rushing to surgery.
Before you attend
Bring photo ID, insurance cards if applicable, a concise list of medicines and allergies, old MRI or X-ray reports on phone or paper, and footwear or clothing that lets the knee or shoulder be examined. Write down three goals—for example, "sleep without waking from knee pain," "jog five kilometres without swelling," or "lift my child safely." Those goals help prioritise whether bracing, injections, structured physiotherapy, arthroscopy, or joint replacement is discussed first.
Using this website responsibly
Articles under the blog section explain common symptoms and treatment concepts in plain language. They are educational, may simplify complex decisions, and should always be confirmed in clinic after examination and, when needed, imaging. If you have severe deformity after injury, numbness or weakness in a limb, high fever with a hot swollen joint, chest pain, shortness of breath, or new bladder or bowel dysfunction with back pain, seek emergency care immediately rather than waiting for an outpatient slot.
